Preliminary W78LE58 8-BIT MICROCONTROLLER GENERAL DESCRIPTION The W78LE58 is an 8-bit microcontroller which has an in-system programmable FLASH-ROM for firmware updating. The instruction set of the W78LE58 is fully compatible with the standard 8052. The W78LE58 contains a 32K bytes of main FLASH-ROM and a 4K bytes of auxiliary FLASH-ROM which allows the contents of the 32KB main FLASH-ROM to be updated by the loader program located at the 4KB auxiliary FLASH-ROM; 512 bytes of on-chip RAM; four 8-bit bi-directional and bit-addressable I/O ports; an additional 4-bit port P4; three 16-bit timer/counters; a serial port. These peripherals are supported by a eight sources two-level interrupt capability.
