WT50F5
8-bit µ C with 8KB Flash Memory, an 8-CH 12-bit A/D Converter and 16x4 LCD Driver
DESCRIPTION
The WT50F5 is a high-performance, low-cost, CMOS 8-bit single-chip microcontroller with 8Kbytes on-chip flash memory, 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, LCD display and short development cycle are required, including industrial control, consumer, communications, and security products. This chip has 8-bit CPU, RAM, flash memory, 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 batterypowered applications, a power saving function is included.
