Design a Custom BoardAbout This Component
1T 8051-compatible 8-bit microcontroller with 16KB flash memory in 20-pin TSSOP package. Part of Nuvoton's NuMicro MS51 Series, featuring integrated clock system, flash memory control with IAP capability, and standard 8051 instruction set architecture. Suitable for embedded control applications requiring compact form factor and moderate code storage.
Package: TSSOP-20 (4.4×6.5mm) · 20 pins
Why does this need a breakout?
Hand-soldering 0.65mm pitch leads is tedious and error-prone; a breakout board with standard 0.1" headers lets you prototype I/O expanders and logic gates on breadboards without a reflow oven. The compact SSOP package also becomes DIP-friendly, eliminating jumper spaghetti and reducing assembly mistakes during development cycles.
