W79E8213 W79E8213RASG -- 80C51 LPC Microcontroller
The W79E8213 series are an 8-bit 4T-8051 microcontroller which has Flash EPROM which is programmable by ICP (In Circuit Program) or by hardware writer. The instruction set of the W79E8213 series are fully compatible with the standard 8052. The W79E8213 series contain a 4K bytes of main Flash EPROM; a 128 bytes of RAM; two 16-bit timer/counters; 4-channel 10-bit PWM; 3 edge detector inputs; 8-channel multiplexed 10-bit A/D convert. The W79E8213 series supports 128 bytes NVM Data Flash EPROM. These peripherals are supported by 10 sources four-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside the W79E8213 series allow the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security.
