This chip can be used dedicate for applications where heart rate and LCD display are required, for example sports bicycle meter, heart rate meter and heart rate watch. This chip has 8-bit CPU, RAM, ROM, I/Os, one 16-bit timer/counters, dual 8-bit timer, interrupt controller, three 8-bit PWM D/A output, resister to frequency converter (RFC), heart rate detect circuits, and a LCD driver. To be suitable for portable battery-powered applications, a power saving function is included. FEATURES u u u u 8-bit single chip micro controller with 8Kbytes ROM and 256 Bytes SRAM Wide voltage operating range from 2.4 V to 5.5 V Built-in 32.768KHz OSC circuits. 14 interrupt sources, 14 halt mode release sources (warm start), 8 off mode wake up sources (cold start); all sources have independent latches each and multi-control is available. u I/O port (32 pins) u I/O port0 u I/O port1 u I/O port1 u I/O port1 u I/O port2 u I/O port3 u I/O port3 8 pins (shared with SEG25~SEG32) 1 pin (shared with OP Amp 1 pins) 3 pins (shared with PWM0~2 output) 4 pins (shared with RFC 4 pins) 8 pins (shared with key detect & event counter inputs) 6 pins (shared with OP Amp 6 pins) 2 pins (shared with BUZ/BUZB output) u u u u u Providing standby mode Key wake up function Build-in heart rate detect circuits and one 16-bit counter Build-in RFC circuit and one 16-bit counter for thermistor and humidity sensor use Dual 8-bit timer & one 16-bit timer/counters Weltrend Semiconductor Inc. 2F, No. 24, Industry East 9th Road, Science-Based Industrial Park, Hsin-chu, TAIWAN TEL: 886-3-5780241 FAX: 886-3-5770419 2 www..com eltrend WT5041 8-bit C with Heart Rate Detect Circuits Version 1.01 u 3 Channel 8-bit PWM output u LCD driver u LCD direct drive (max. 16-digit display at 1/4 duty) u 1/4, 1/3, 1/2 duties and 1/2, 1/3 biases can be selected by software programming u 1/4, 1/3, 1/2 duties and 1/2, 1/3 biases can be selected by software programming u LCD segments SEG25~32 can be used as 8 I/O pins by software programming u Real-time emulator u Package: Die form Weltrend Semiconductor Inc. 2F, No. 24, Industry East 9th Road, Science-Based Industrial Park, Hsin-chu, TAIWAN TEL: 886-3-5780241 FAX: 886-3-5770419 3 www..com eltrend WT5041 8-bit C with Heart Rate Detect Circuits Version 1.01 PIN FUNCTION Name COM1 COM2 COM3 COM4 SEG1 SEG2 SEG3 SEG4 SEG5 SEG6 SEG7 SEG8 SEG9 SEG10 SEG11 SEG12 SEG13 SEG14 SEG15 SEG16 SEG17 SEG18 SEG19 SEG20 SEG21 SEG22 SEG23 SEG24 P00/SEG25 P01/SEG26 P02/SEG27 P03/SEG28 P04/SEG29 P05/SEG30 P06/SEG31 P07/SEG32 P30/IN1 P31/IN2 P32/IN3 P33/O1 No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 I/O O O O O O O O O O O O O O O O O O O O O O O O O O O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O I/O Description LCD common 1.
