W78E58B 8-BIT MICROCONTROLLER 1. GENERAL DESCRIPTION The W78E58B is an 8-bit microcontroller which has an in-system programmable Flash EPROM for firmware updating. The instruction set of the W78E58B is fully compatible with the standard 8052. The W78E58B contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary ROM; 512 bytes of on-chip RAM; four 8-bit bi-directional and bit-addressable I/O ports; an additional 4bit port P4; three 16-bit timer/counters; a serial port. These peripherals are supported by a eight sources two-level interrupt capability.
