DescriptionThe AT32UC3A464S is designed as one kind of complete system-on-chip microcontroller device that 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. And AT32UC3A464S also features many communication interfaces for communication intensive applications like UART, SPI or TWI. Additionally, a flexible Synchronous Serial Controller (SSC) is available.
Features of the AT32UC3A464S are:(1)Four Universal Synchronous / Asynchronous Receiver / Transmitters (USART);(2)Two Three-Channel 16-bit Timer/Counter (TC);(3)One 8-channel 10-bit Analog-To-Digital Converter, multiplexed with Digital IOs;(4)On-Chip Transceivers Including Pull-Ups;(5)Flexible End-Point Configuration and Management with Dedicated DMA Channels;(6)256KBytes, 128KBytes, 64KBytes versions;(7)Single-Cycle Flash Access up to 36MHz;(8)4 ms Page Programming Time and 8ms Full-Chip Erase Time;(9)100,000 Write Cycles, 15-year Data Retention Capability;(10)Autovectored Low Latency Interrupt Service with Programmable Priority.etc.
The absolute maximum ratings of the AT32UC3A464S can be summarized as:(1)Operating Temperature: -40°C to +85°C;(2)Storage Temperature: -60°C to +150°C;(3)Voltage on Input Pin with respect to Ground: -0.3V to 3.6V;(4)Maximum Operating Voltage (VDDCORE): 1.95 V;(5)Maximum Operating Voltage (VDDIO): 3.6V;(6)Total DC Output Current on all I/O Pin: 370 mA.
The electrical characteristics of AT32UC3A464S can be summarized as:(1)VDDCORE rise rate to ensure poweron-reset: 0.01 V/ms;(2)VDDCORE fall rate to ensure poweron-reset: 0.01 to 400 V/ms;(3)Rising threshold voltage: voltage up to which device is kept under reset by POR on rising VDDCORE: 1.35 to 1.6 V;(4)Falling threshold voltage: voltage when POR resets device on falling VDDCORE: 1.25 to 1.4 V;(5)Time for reset signal to be propagated to system: 200 to 400 s.
