Product introduction

The BJ8M601A is a single chip 8-bit MCU based on RISC architecture with built-in 2K×16-bit MTP program memory. It is manufactured using an advanced CMOS process withlow power consumption characteristics and low operating voltage capability. The chip integrates a multi-channel 12-bit A/D converter, as well as two timer modules that provide timing, counting and PWM functions. Internal watchdog, low voltage reset, low voltage detection functions ensure the reliable operation of the system. At the same time, it provides a rich clock options, including internal fast clock, internal slow clock, external crystal clock and external input clock, so that users can use flexibly. In addition, the MCU includes rich IO resources and can be widely used in various products.
