The high-performance, low-power 32-bit AVR RISC-based microcontroller combines 128KB flash memory, 32KB SRAM, full-speed (12 Mbps) USB Mini-host + device, and I2S. The MCU achieves 83 Dhrystone MIPS (DMIPS) at 60MHz and consumes only 23mA at 3.3 volts.
The microcontroller's Memory Protection Unit (MPU) and fast, flexible interrupt controller support the latest real-time operating systems. The Peripheral Direct Memory Access (PDMA) controller transfers data between peripherals and memories without processor involvement, drastically reducing processing overhead with large continuous data streams between MCU modules.
The power manager improves design flexibility and security: the on-chip brown-out detector monitors the power supply, the CPU is run by the on-chip RC oscillator or one of external oscillator sources, and the Real-Time Clock (RTC) and its associated timer track time.
The AT32UC3B0128AU is the Audio version of the AT32UC3B0128. It allows the execution of Atmel licensed Audio firmware IPs.
Two versions are available:
BuildingAutomation: 舒适性与控制
HomeEntertainment: 音频
MobileElectronics: 便携式音频播放器, 移动电话和移动互联网设备
PCPeripherals: 音频 I/O 设备
