Design a Custom BoardAbout This Component
Microchip CryptoAuthentication IC providing hardware-based cryptographic security with 256-bit key storage for up to 16 keys. Features SHA-256 hashing, HMAC, and UART/I2C interfaces with 4.5KB EEPROM for secure key storage. Designed for anti-cloning, secure boot, ecosystem control, and message authentication in embedded systems.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
