General Description
The device is an 8-bit high performance RISC-like microcontroller designed for multiple I/O product applications. The device is particularly suitable for use in products such as remote controllers, fan/light controllers, washing machine controllers, scales, toys and various subsystem controllers. A halt feature is
included to reduce power consumption.
The program and option memories can be electrically programmed, making the microcontroller suitable for use in product development.
