The AT32UC3A0128 is a 32-bit AVR RISC-based microcontroller designed for high-performance, low-power applications. It operates at frequencies up to 66 MHz, achieving up to 91 Dhrystone MIPS (DMIPS) while consuming only 40 mA at 3.3V. The device features 128KB of flash memory and 32KB of SRAM, with a Peripheral Direct Memory Access (PDCA) controller that facilitates efficient data transfers between peripherals and memory without processor intervention. This microcontroller includes a 10/100 Mbps Ethernet MAC, a full-speed USB 2.0 interface with embedded host capability, and supports various communication protocols including I2S. The AT32UC3A0128AU variant is specifically tailored for audio applications, allowing the execution of Microchip licensed audio firmware IPs. It is available in an LQFP144 package suitable for industrial temperature ranges from -40¬8C to +85¬8C. The combination of features makes it suitable for cost-sensitive embedded applications requiring robust performance and low power consumption.
The high-performance, low-power 32-bit AVR RISC-based microcontroller combines 128KB flash, 32KB SRAM, 10/100 ethernet MAC, full-speed (12 Mbps) USB 2.0 with embedded host capability, I2S, and a built-in audio D/A converter.
This device features SRAM/SDRAM external bus interface and achieves 91 Dhrystone MIPS (DMIPS) at 66MHz while consuming only 40mA 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.
