W78E58 GENERAL DESCRIPTION 8-BIT MICROCONTROLLER The W78E58 is an 8-bit microcontroller that is functionally compatible with the W78C58, except that the mask ROM is replaced by a flash EEPROM with a size of 32 KB. To facilitate programming and verification, the flash EEPROM inside the W78E58 allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security. The W78E58 microcontroller supplies a wider frequency range than most 8-bit microcontrollers on the market. It is functionally compatible with the industry-standard 80C52 microcontroller series, except that one extra 4-bit bit-addressable I/O port(Port 4) and two additional external interrupts (INT2 , INT3 ).
