描述 Description

The WT5053 is a high-performance, low-cost, CMOS 8-bit single-chip microcontroller with 4Kbytes on-chip ROM, an 8-channel 12-bit analog to digital converter. This chip is suitable for variable applications, especially where analog signal (sensor output) to digital signal conversion is 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, and an 8-channel 12-bit A/D converter. To be suitable for portable battery-powered applications, a power saving function is included.
