W78E51B-24 - Brand New Winbond Electronics IC Chips
-
Description
The W78E51B-24 is an 8-bit microcontroller designed for various electronic applications. It offers a wider frequency range while consuming low power. This microcontroller is fully compatible with the standard 8051 instruction set. It features a 4K bytes MTP ROM (Multiple-Time Programmable ROM) for program storage and a 128 bytes RAM for data storage. Additionally, it includes four 8-bit bi-directional and bit-addressable I/O ports, an extra 4-bit I/O port, two 16-bit timer/counters, a hardware watchdog timer, and a serial port. The W78E51B-24 also supports seven sources two-level interrupt capability. For convenience and security, the program memory can be electronically programmed and read using the built-in MTPROM. Once the code is confirmed, it can be protected for security purposes.
