The AT32UC3A364S flash microcontroller is designed for exceptionally high data throughput with Hi-Speed USB OTG, SD/ SDIO card, Multi-Level-Cell (MLC) NAND flash with ECC and SDRAM interfaces. Designed with the multi-layered AVR32 databus, 128 KB on-chip SRAM with triple high speed interfaces, and multi-channel Peripheral and memory to memory DMA controller, the AT32UC3A364S offers outstanding data throughput. The device also features a Hi-Fi stereo Audio DAC, and a full duplex multi-channel I2S audio interface.
The AT32UC3A364S features an AES crypto module, capable of 128 to 256-bit AES encryption at speeds of up to 22.8 MBytes/s. Note that export restrictions apply to this variant.
The AT32UC3A3 is a complete System-On-Chip microcontroller based on the AVR32 UC RISC processor running at frequencies up to 66MHz. AVR32 UC is a high-performance 32-bit RISC microprocessor core, designed for cost-sensitive embedded applications, with particular emphasis on low power consumption, high code density and high performance. The processor implements a Memory Protection Unit (MPU) and a fast and flexible interrupt controller for supporting modern operating systems and real-time operating systems. Higher computation capabilities are achievable using a rich set of DSP instructions.
The AT32UC3A3 incorporates on-chip Flash and SRAM memories for secure and fast access. The Peripheral Direct Memory Access Controller (PDCA) enables data transfers between peripherals and memories without processor involvement. The PDCA drastically reduces processing overhead when transferring continuous and large data streams. The Direct Memory Access controller (DMACA) allows high bandwidth data flows between high speed peripherals (USB, External Memories, MMC, SDIO, ...) and through high speed internal features (AES, internal memories). The Power Manager improves design flexibility and security: the on-chip Brown-Out Detector monitors the power supply, the CPU runs from the on-chip RC oscillator or from one of external oscillator sources, a Real-Time Clock and its associated timer keeps track of the time. The Device includes two sets of three identical 16-bit Timer/Counter (TC) channels. Each channel can be independently programmed to perform frequency measurement, event counting, interval measurement, pulse generation, delay timing and pulse width modulation. 16-bit channels are combined to operate as 32-bit channels.
The AT32UC3A3 also features many communication interfaces for communication intensive applications like UART, SPI or TWI. Additionally, a flexible Synchronous Serial Controller (SSC) and an USB are available. The SSC provides easy access to serial communication protocols and audio standards like I2S. The High-Speed (480MBit/s) USB 2.0 Device interface supports several USB Classes at the same time thanks to the rich Endpoint configuration. The On-The-Go (OTG) Host interface allows device like a USB Flash disk or a USB printer to be directly connected to the processor.
AT32UC3A3 integrates a class 2+ Nexus 2.0 On-Chip Debug (OCD) System, with non-intrusive real-time trace, full-speed read/write memory access in addition to basic runtime control.
