WT5058
8-bit µ C with 8KB ROM, an 8-CH
12-bit A/D Converter and 16x4 LCD Driver
DESCRIPTION
The WT5058 is a high-performance, low-cost, CMOS 8-bit single-chip microcontroller with
8Kbytes on-chip ROM, an 8-channel 12-bit analog to digital converter and 16x4 LCD driver. This
chip is suitable for variable applications, especially where analog signal (sensor output) to digital
signal conversion and LCD display are required, including industrial control, consumer,
communications, and security products.
This chip has 8-bit CPU, RAM, ROM, I/Os, dual 16-bit timer/counters, interrupt controller, 16x4
LCD driver and an 8-channel 12-bit A/D converter. To be suitable for portable battery-powered
applications, a power saving function is included.
FEATURES
u 8-bit single chip microcontroller with 8K bytes ROM and 384bytes SRAM
