AT32UC3A3256S-CTUT

The Microchip Technology AT32UC3A3256S-CTUT is a high-performance, low-power 32-bit AVR microcontroller. It features a compact single-cycle RISC instruction set with DSP capabilities, capable of performing up to 1.51 DMIPS/MHz. This device includes 256KB of internal high-speed Flash memory with 100,000 write cycles and 15-year data retention, alongside 128KB of internal high-speed SRAM.

Key features include a Memory Protection Unit, a multi-layer bus system for high-performance data transfers, and multiple DMA channels to improve peripheral communication speed. The microcontroller supports external memories such as SDRAM, SRAM, and NandFlash, and external storage devices like MMC and SD cards. It also integrates an Advanced Encryption System (AES) and a High-Speed USB 2.0 interface.

Designed for surface mounting, the AT32UC3A3256S-CTUT comes in a 144-TFBGA package. It operates within a temperature range of -40°C to 85°C and utilizes an internal oscillator type. Its extensive peripheral set includes an 8-channel 10-bit ADC, multiple Timer/Counters, and Universal Synchronous/Asynchronous Receiver/Transmitters (USARTs), making it suitable for a wide range of embedded applications.
