WT5041
8-bit µ C with Heart Rate Detect Circuits
Version 1.01
DESCRIPTION
The WT5041 is a high-performance, low-cost, CMOS 8-bit single-chip micro controller
with on-chip OP Amp (OPA) for heart rate detect and 128 segments LCD driver. 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 8-bit single chip micro controller with 8Kbytes ROM and 256 Bytes SRAM
u Wide voltage operating range from 2.4 V to 5.5 V
u Built-in 32.768KHz OSC circuits.
