W79E804A/803A/802A
1. 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.
