Description
The W78E51CP-40 is an 8-bit microcontroller that falls under the product category of IC Chips. It is known for its wide frequency range and low power consumption. The W78E51CP-40 has a fully compatible instruction set with the standard 8051 microcontroller. It comes equipped with a 4K bytes Flash EPROM, 128 bytes RAM, four 8-bit bi-directional and bit addressable I/O ports, an additional 4-bit I/O port P4, two 16-bit timer/counters, a hardware watchdog timer, and a serial port. These peripherals are supported by a two-level interrupt capability consisting of seven sources. The Flash EPROM inside the W78E51CP-40 allows for electronic programming and verification of the program memory. Additionally, once the code is confirmed, the user can protect the code for security.
