GENERAL DESCRIPTION

The W79E804 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) or by hardware writer.

The instruction set of the W79E804 series are fully compatible with the standard 8052. The W79E804

series contain a 8K/4K/2K bytes of main Flash EPROM; a 256 bytes of RAM; 256 bytes NVM Data

Flash EPROM; two 8-bit bi-directional, one 2-bit bi-directional and bit-addressable I/O ports; two 16-bit

timer/counters; 4-channel 10-bit PWM; two serial ports that include a I2C and an enhanced full duplex

serial port. These peripherals are supported by 12 sources four-level interrupt capability. To facilitate

programming and verification, the Flash EPROM inside the W79E804 series allow the program

memory to be programmed and read electronically. Once the code is confirmed, the user can protect

the code for security.
