About this product
8-bit 8051-compatible microcontroller from Winbond in a 40-pin DIP package, suited for breadboard prototyping and existing 8051 designs. It follows the standard 8051 instruction set, so much 8051 code and tooling can be reused. Verify the supply voltage and clock limits in the Winbond datasheet before wiring it.

Frequently asked questions
Can I use it on a breadboard?
Yes, the DIP-40 package fits standard breadboards and sockets. Confirm the supply voltage and pinout in the datasheet before wiring.
Can I program it with standard 8051 tools?
It is 8051-compatible, so many 8051 toolchains are usable, but the programming method depends on the Winbond datasheet and the programmer you have.
