AT32UC3A1256-AUT Microcontrollers - MCU by Microchip Technology
| Status: | Active |
|---|---|
| Series: | AT32UC3A1256 |
| RoHS: | Compliant |
The MCU achieves 91 Dhrystone MIPS (DMIPS) at 66 MHz while consuming only 40 mA at 3.3V.
The Peripheral Direct Memory Access (PDCA) controller transfers data between peripherals and memories without processor involvement, drastically reducing processing with continuous large data streams within the MCU.
The AT32UC3A1256AU is the Audio version of the AT32UC3A1256. It allows the execution of Microchip licensed Audio firmware IPs.
One version is available:
- AT32UC3A1256AU-AUR: TQFP100, industrial (-40°C to +85°C), reel conditioning.
