This device integrates high‑performance analog signal processing with a secure, feature‑rich microcontroller in a compact, low‑power design. It includes a multichannel 12‑bit, 2 MSPS ADC supporting up to 16 external channels, multiple on‑chip voltage and temperature monitors, and 12‑bit DACs with high current drive and an integrated low‑drift voltage reference. A 32‑bit Arm Cortex‑M33 core with FPU, flexible clocking, large Flash and SRAM with ECC, and extensive on‑chip peripherals enable robust embedded control and connectivity.
The platform supports a wide range of serial interfaces, configurable GPIO voltage levels, timers, PWM, and programmable logic, along with advanced security features such as Arm TrustZone, secure boot, hardware cryptography accelerators, and true random number generation. Designed for reliability and low‑power operation, it supports multiple supply options, in‑circuit reprogramming, and operates across an extended industrial temperature range. Development is supported by low‑cost tools and broad third‑party ecosystem support.
APPLICATIONS
- Optical networking 400G/800G/1.6T and higher frequency modules
