The W78E858 is an 8-bit microcontroller which has an in-system programmable Flash EPROM for firmware updating. The instruction set of the W78E858 is fully compatible with the standard 8052. The W78E858 contains a 32K bytes of main Flash EPROM and a 4K bytes of auxiliary Flash EPROM which allows the contents of the 32KB main Flash EPROM to be updated by the loader program located at the 4KB auxiliary Flash EPROM ROM; 768 bytes of on-chip RAM; 128 bytes of EEPROM, 8 extra power down wake-up through INT2 to INT9; 4 channel 8-bit PWM; four 8-bit bi-directional and bit-addressable I/O ports; an additional 4-bit port P4; three 16-bit timer/counters where the TIMER2 with programmable clock output and 17-bit watchdog timer are built in this device; a serial port. These peripherals are supported by a eight sources two-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside the W78E858 allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security.
