Product Summary

The W78E54-24 is an 8-bit microcontroller that is functionally compatible with the W78C54, except that the mask ROM is replaced by a flash EEPROM with a size of 16 KB. To facilitate programming and verification, the flash EEPROM inside the W78E54-24 allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security. The W78E54-24 microcontroller supplies a wider frequency range than most 8-bit microcontrollers on the market. The W78E54-24 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 ).
