Introduction
The W79E4051/2051 series are an 8-bit Turbo 51 microcontroller which has an in-system programmable Flash EPROM which Flash EPROM can program by ICP (In Circuit Program) Writer. The instruction set of the W79E4051/2051 series are fully compatible with the standard 8052. The W79E4051/2051 series contain a 4K/2K bytes of program Flash EPROM; a 256 bytes of RAM; 128 bytes data Flash EPROM for customer data storage; two 8-bit bi-directional and bit-addressable I/O ports; two 16-bit timer/counters; an enhanced full duplex serial port; 1 channel PWM by 10-bit counter, Brownout voltage detection/reset, Power on reset detection and one analog comparator. These peripherals are supported by 9 sources of four-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside the W79E4051/2051 series allow the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security.
