SmartDV’s Single-Wire Interface (SWI) Controller IP is a silicon-proven, fully featured single-wire serial communication solution purpose-built for SoC designs requiring reliable, low-pin-count connectivity to Atmel/Microchip CryptoAuthentication devices such as the ATECC608 series across IoT, security, industrial, and embedded applications. Compatible with the Atmel/Microchip Single Wire Interface specification and designed for standard UART peripheral compatibility, it delivers complete SWI controller functionality over a single data line, enabling secure communication with CryptoAuthentication ICs for key storage, authentication, and cryptographic operations with minimal GPIO requirements.
Designed for the practical integration requirements of modern IoT and security-focused SoC designs, the IP provides a simple, reliable interface to the full range of Microchip CryptoAuthentication devices including the ATECC608 series for elliptic curve cryptography, ECDSA, ECDH, and AES operations. Its single-wire architecture minimizes GPIO consumption and connector pin count, making it ideal for space and pin-constrained IoT edge devices and embedded security modules where hardware-based cryptographic authentication is required.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its parameterized architecture and clean host interface enable fast integration and confident design bring-up across a wide range of process nodes and target applications.
