DrawingsSectionTOP VIEW3.7mm x4.0mm x 1.5mmBOTTOM VIEWTO-921 2 31-Wire is a registered trademark of Dallas Semiconductor.TSOC PACKAGEDESCRIPTIONThe DS2401 enhanced Silicon Serial Number is a low-cost, electronic registration number that provides an absolutely unique identity which can be determined with a minimal electronic interface (typically, a single port pin of a microcontroller). The DS2401 consists of a factory-lasered, 64-bit ROM that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (01h). Data is transferred serially via the 1-Wire protocol that requires only a single data lead and a ground return. Power for reading and writing the device is derived from the data line itself with no need for an external power source. The DS2401 is an upgrade to the DS2400. The DS2401 is fully reverse-compatible with the DS2400 but provides the additional multi-rop capability that enables many devices to reside on a single data line. The familiar TO-92, SOT-223 or TSOC package provides a compact enclosure that allows standard assembly equipment to handle the device easily.OPERATIONThe DS2401’s internal ROM is accessed via a single data line. The 48-bit serial number, 8-bit family code and 8-bit CRC are retrieved using the Dallas 1-Wire protocol. This protocol defines bus transactions in terms of the bus state during specified time slots that are initiated on the falling edge of sync pulses from the bus master. All data is read and written least significant bit first.1-WIRE BUS SYSTEMThe 1-Wire bus is a system which has a single bus master system and one or more slaves. In all instances, the DS2401 is a slave device. The bus master is typically a microcontroller. The discussion of this bus system is broken down into three topics: hardware configuration, transaction sequence, and 1-Wire signaling (signal type and timing). For a more detailed protocol description, refer to Chapter 4 of the Book of DS19xx iButton® Standards.Hardware ConfigurationThe 1-Wire bus has only a single line by definition; it is important that each device on the bus be able to drive it at the appropriate time. To facilitate this, each device attached to the 1-Wire bus must have an open-drain connection or 3-state outputs. The DS2401 is an open-drain part with an internal circuit equivalent to that shown in Figure 2. The bus master can be the same equivalent circuit. If a bidirectional pin is not available, separate output and input pins can be tied together. The bus master requires a pullup resistor at the master end of the bus, with the bus master circuit equivalent to the one shown in Figure 3. The value of the pullup resistor should be approximately 5k W for short line lengths. A multidrop bus consists of a 1-Wire bus with multiple slaves attached. The 1-Wire bus has a maximum data rate of 16.3kbits per second.The idle state for the 1-Wire bus is high. If, for any reason, a transaction needs to be suspended, the bus MUST be left in the idle state if the transaction is to resume. If this does not occur and the bus is left low for more than 120m s, one or more of the devices on the bus may be reset.DS2401 MEMORY MAP Figure 18-Bit CRC Code48-Bit Serial Number8-Bit Family Code (01h) MSB LSB MSB LSB MSB LSBiButton is a registered trademark of Dallas Semiconductor.DS2401 EQUIVALENT CIRCUIT Figure 2BUS MASTER CIRCUIT Figure 3A) Open DrainSee noteTo data connectionof DS2401B) Standard TTLSee noteTo data connectionof DS2401Note:Depending on the 1-Wire communication speed and the bus load characteristics, the optimal pullup resistor (R PU) value will be in the 1.5k W to 5k W range.TRANSACTION SEQUENCEThe sequence for accessing the DS2401 via the 1-Wire port is as follows:§Initialization§ROM Function Command§Read DataINITIALIZATIONAll transactions on the 1-Wire bus begin with an initialization sequence. The initialization sequence consists of a reset pulse transmitted by the bus master followed by a Presence Pulse(s) transmitted by the slave(s).The Presence Pulse lets the bus master know that the DS2401 is on the bus and is ready to operate. For more details, see the 1-Wire Signaling section.ROM FUNCTION COMMANDSOnce the bus master has detected a presence, it can issue one of the four ROM function commands. All ROM function commands are 8 bits long. A list of these commands follows (refer to flowchart in Figure 4):Read ROM [33h] or [0Fh]This command allows the bus master to read the DS2401’s 8-bit family code, unique 48-bit serial number, and 8-bit CRC. This command can only be used if there is a single DS2401 on the bus. If more than one slave is present on the bus, a data collision will occur when all slaves try to transmit at the same time (open drain will produce a wired-AND result). The DS2401 Read ROM function will occur with a command byte of either 33h or 0Fh in order to ensure compatibility with the DS2400, which will only respond to a 0Fh command word with its 64-bit ROM data.Match ROM [55h] / Skip ROM [CCh]The complete 1-Wire protocol for all Dallas Semiconductor iButtons contains a Match ROM and a Skip ROM command. (See the Book of DS19xx iButton Standards.) Since the DS2401 contains only the 64-bit ROM with no additional data fields, the Match ROM and Skip ROM are not applicable and will cause no further activity on the 1-Wire bus if executed. The DS2401 does not interfere with other 1-Wire parts on a multidrop bus that do respond to a Match ROM or Skip ROM (for example, a DS2401 and DS1994 on the same bus).Search ROM [F0h]When a system is initially brought up, the bus master might not know the number of devices on the 1-Wire bus or their 64-bit ROM codes. The search ROM command allows the bus master to use a process of elimination to identify the 64-bit ROM codes of all slave devices on the bus. The ROM search process is the repetition of a simple 3-step routine: read a bit, read the complement of the bit, then write the desired value of that bit. The bus master performs this simple 3-step routine on each bit of the ROM. After one complete pass, the bus master knows the contents of the ROM in one device. The remaining number of devices and their ROM codes may be identified by additional passes. See Chapter 5 of the Book of DS19xx iButton Standards for a comprehensive discussion of a ROM search, including an actual example.1-WIRE SIGNALINGThe DS2401 requires a strict protocol to ensure data integrity. The protocol consists of four types of signaling on one line: reset sequence with Reset Pulse and Presence Pulse, write 0, write 1, and read data. All these signals except Presence Pulse are initiated by the bus master.The initialization sequence required to begin any communication with the DS2401 is shown in Figure 5.A reset pulse followed by a Presence Pulse indicates the DS2401 is ready to send or receive data given the correct ROM command.The bus master transmits (T X) a reset pulse (t RSTL, minimum 480m s). The bus master then releases the line and goes into receive mode (R X). The 1-Wire bus is pulled to a high state via the 5k W pullup resistor. After detecting the rising edge on the data pin, the DS2401 waits (t PDH, 15-60m s) and then transmits the Presence Pulse (t PDL, 60-240m s). The 1-Wire bus requires a pullup resistor range of 1.5k W to 5k W, depending on bus load characteristics.READ/WRITE TIME SLOTSThe definitions of write and read time slots are illustrated in Figure 6. All time slots are initiated by the master driving the data line low. The falling edge of the data line synchronizes the DS2401 to the master by triggering a delay circuit in the DS2401. During write time slots, the delay circuit determines when the DS2401 will sample the data line. For a read data time slot, if a “0” is to be transmitted, the delay circuit determines how long the DS2401 will hold the data line low overriding the “1” generated by the master. If the data bit is a 1, the DS2401 will leave the read data time slot unchanged.ROM FUNCTIONS FLOW CHART Figure 4INITIALIZATION PROCEDURE “RESET AND PRESENCE PULSES” Figure 5480m s £ t RSTL < ¥ *480m s £ t RSTH < ¥ (includes recovery time)15m s £ t PDH < 60m s 60m s £ t PDL < 240m s* In order not to mask interrupt signaling by other devices on the 1-Wire bus, t RSTL + t R should always be less than 960m s.READ/WRITE TIMING DIAGRAM Figure 6Write-One Time Slot60m s £ t SLOT < 120m s 1m s £ t LOW1 < 15m s 1m s £ t REC < ¥RESISTOR MASTERRESISTOR MASTER DS2401READ/WRITE TIMING DIAGRAM (cont’d) Figure 6Write-zero Time Slot60m s £ t LOW0 < t SLOT < 120m s 1m s £ t REC < ¥Read-data Time Slot60m s £ t SLOT < 120m s 1m s £ t LOWR < 15m s 0 £ t RELEASE < 45m s 1m s £ t REC < ¥ t RDV = 15m s t SU < 1m sCRC GENERATIONTo validate the data transmitted from the DS2401, the bus master may generate a CRC value from the data as it is received. This generated value is compared to the value stored in the last 8 bits of the DS2401. If the two CRC values match, the transmission is error-free.The equivalent polynomial function of this CRC is: CRC = x 8 + x 5 + x 4 + 1. For more details, see the Book of DS19xx iButton Standards .CUSTOM DS2401Customization of a portion of the unique 48-bit serial number by the customer is available. Dallas Semiconductor will register and assign a specific customer ID in the 12 most significant bits of the 48-bit field. The next most significant bits are selectable by the customer as a starting value, and the least significant bits are non-selectable and will be automatically incremented by one. Certain quantities and conditions apply for these custom parts.

If a 5k W resistor is used topullup the I/O line to V CC, 5m s after power has been applied the parasite capacitance will not affect normal communications.10)The reset low time (t RSTL) should be restricted to a maximum of 960m s, to allow interrupt signaling,otherwise it could mask or conceal interrupt pulses if this device is used in parallel with a DS2404 or DS1994.11)Under certain low voltage conditions, V ILMAX may have to be reduced to as much as 0.5V to alwaysguarantee a Presence Pulse.12)The optimal sampling point for the master is as close as possible to the end time of the t RDV periodwithout exceeding t RDV. For the case of a Read-One Time slot, this maximizes the amount of time for the pullup resistor to recover to a high level. For a Read-Zero Time slot, it ensures that a read will occur before the fastest 1-Wire device(s) releases the line.13)The duration of the low pulse sent by the master should be a minimum of 1µs with a maximum valueas short as possible to allow time for the pullup resistor to recover the line to a high level before the 1-Wire device samples in the case of a Write-One Time or before the master samples in the case of a Read-One Time.。
