IS3XCS8977 触控按键评估板应用用户指南说明书
IS3XCS8977 Touch Key Application User GuideRev. A2022-04-12GENERAL DESCRIPTIONCS8977 is a general-purpose MCU with 64KB Code e-Flash memory with ECC and 2KB SRAM with ECC. The embedded flash for code storage has built-in ECC that corrects one-bit errors and detects two-bit errors. CPU accesses the e-Flash through program address read and through Flash Controller which can perform software read/write operations of e-Flash.CS8977 has a 1-T 8051 with enhanced multiplication and division accelerator. There are three clock sources for system. One is a 16MHz/32MHz IOSC (manufacturer calibration+/- 2%), one is XCLK, and the other one is SOSC32KHz (typical 32KHz) which is divided from slow oscillator. ALL clock sources have a clock programmable divider for scaling down the frequency to save power dissipations. The clock selections are combined with flexible power management schemes, including NORMAL, STOP, and SLEEP modes to balance speed and power consumption.There are T0/T1/T2/T3/T4/T5 timers coupled with CPU and three WDTs where WDT1 is clocked by SYSCLK, and WDT2/WDT3 are clocked by a non-stop SOSC32KHz. An 8-bit/16-bit checksum and 16-bit CRC accelerator is included. There are EUART/LIN controllers, I2C master/Slave controllers and SPI master/slave controller. The interfaces of these controllers are multiplexed with GPIO pins. Other useful peripherals include a buzzer control, six 8/10/12-bit PWMs, one channel of 16-bit timer/capture, and one 16-bit quadrature decoder. There are also 16 channels 8-bit PWM for LED control.Analog peripherals include a 12-bit ADC with internal temperature sensor, an 8-bit voltage output DAC, and four analog comparators with programmable threshold. A touch key controller with up to 20-bit resolution is included. The touch key controller has shield output capability for moisture immunity and allows auto-detection wakeup from sleep mode (under 20uA). The maximum number of key inputs can be scanned is 27. The touch key controller can also be used for proximity sensing.CS8977 provides a flexible means of flash programming that supports ISP and IAP. The protection of data loss is implemented in hardware by access restriction of critical storage segments. The code security is reinforced with sophisticated writer commands and ISP commands. The on-chip break point processor also allows easy debugging which can be integrated with ISP. Reliable power-on-reset circuit and low supply voltage detection allow reliable operations under harsh environments.FEATURESCPU and Memory♦Up to 32MHz 1-Cycle 8051 CPU core♦16-bit Timers T0/T1/T2/T3/T4 and 24-bit Timer T5 ♦Checksum and CRC accelerator♦WDT1 by SYSCLK, WDT2/WDT3 bySOSC32KHz♦Clock fault monitoring♦Up to 6 external interrupts shared with GPIO pins ♦Power saving modes – Normal, STOP, and SLEEP modes♦256B IRAM and 1792B XRAM with ECC check♦64KB Code e-Flash with ECC and two 128x16 Information Block▪Code security and data loss protection▪100K endurance and 10 years retention Clock Sources♦Internal oscillator at 16MHz/32MHz(+/- 2%) ▪Spread Spectrum option♦Internal low power oscillator 128KHz/256KHz♦External clock option and clock outDigital Peripherals♦ 6 CH 8/10/12-bit center-aligned PWM controller ▪Trigger interrupt and ADC conversion♦16 CH 8-bit PWM left/right aligned♦One 16-bit Timer/Capture and One 16-bit quadrature decoder♦Buzzer/Melody generator♦One I2C Master♦One I2C Slave – also for ISP and debug♦One SPI Master/ Slave Controller♦One EUART1 and one EUART2/LINAnalog Peripherals♦Capacitance sense touch-key controller - scan up to 27 key▪Shield output for moisture immunity▪Low power sleep mode wakeup (<20uA).▪Active Proximity sensing front-end♦12-Bit SAR ADC with GPIO analog input▪Track and hold▪Temperature sensor and supply measurement ♦8-Bit DAC and four analog comparators♦Power on reset and Low voltage detect (2.2V-4.5V)Miscellaneous♦Up to 28 GPIO pins with multi-function options ▪Configurable IO structure and noise filters♦ 2.3V to 5.5V single supply♦Active current < 150uA/MHz in Normal mode♦Low power standby (1uA) in SLEEP mode♦Operating temperature -40°C t0 85°C♦TSSOP20/24/28, QFN-32 and LQFP32 package (RoHS compliant)ORDERING INFORMATIONTable 1: Ordering InformationFor pricing, delivery, and ordering information, please contact LUMISSIL’s marketing and sales team at https:///company/office-locations or (408) 969-6600.Copyright © 2021~2022 Lumissil Microsystems.

Please refer above Figure 12 for below descriptions.1.) Four layers of PCB is recommended to have betterperformance.2.) In case, two-layer PCB is a must. Put the IC,sensor-related components, and sensor traces on the bottom layer. It is highly recommended toprovide a whole ground plane upon the top layer over IC and sensor related-components to haveless emissions.3.) Rs and Cs should be placed as close as possibleto IC.4.) Choose qualified by-pass capacitors and placethem as close as possible to the IC VDDC andVCC pins to provide the best decoupling.5.) Cref should be placed as close as possible to IC.6.) Reduce the capacitance of a touch sensor. Thereshould be no copper-filled, grounding or signalrouting within the sensor area.7.) Reduce signals trace length. A long PCB tracelength can form a proximity sensor.8.) Sensor traces should not be close tocommunication lines like I2C, UART.9.) Sensor traces should not be close to control signallines like LED control lines, LED power lines, …, etc..10.) Place a guard ring on the perimeter of the PCBand connect the guard ring to the chassis ground.Mechanical design will also play an important role for better performance in addition to PCB layout.SCHEMATICS OF IS3XCS8977 TOUCH KEY EVALUATION BOARD - EBGUIFigure 13: IS3XCS8977 EBGUI Application Schematics - 1Figure 14: IS3XCS8977 EBGUI Application Schematics - 2Figure 15: IS3XCS8977 EBGUI Application Schematics - 3Figure 16: IS3XCS8977 EBGUI Component Placement - Top LayerFigure 17: IS3XCS8977 EBGUI PCB Layout - Top LayerFigure 18: IS3XCS8977 EBGUI Component Placement - Bottom LayerFigure 19: IS3XCS8977 EBGUI PCB Layout - Bottom LayerBILL OF MATERIALSTable 2: Bill of Materials For Bill of Materials, please refer above Figure 13, Figure 14 and Figure 15.REVISION HISTORYAPPENDIX I: IS3XCS8977 Test Code －GPIO toggle#include "CS8977_SFR.h"#include "CS8977_XFR.h"#include "CS8977_MCU.h"#include "CS8977_EUART2.h"#include "Global.h"#include <intrins.h>//=================================================================== /***Initial_REGTRM**REGTRM value for 1.5V**/void Initial_REGTRM(unsigned char regtrm){TB = 0xAA;TB = 0x55;REGTRM = regtrm;TB = 0x00;}//=================================================================== /***Initial_IOSC**IOSC ITRM value and IOSC VTRM value for 16MHz**/void Initial_IOSC(unsigned char ITRM, unsigned char VTRM){TB = 0xAA;TB = 0x55;IOSCITRM = ITRM;TB = 0x00;Delay10ms(1);TB = 0xAA;TB = 0x55;IOSCVTRM = VTRM;TB = 0x00;}//=================================================================== /***IFB_Read_1Byte**Read 1 byte from Information block IFB**/unsigned char IFB_Read_1Byte(unsigned char ADD){unsigned char IFB_DAT;TB = 0xAA;TB = 0x55;FLSHADH = 0x00;FLSHADL = ADD;FLSHCMD = 0x02;
