AT91SAM7S256-AU

The AT91SAM7S256-AU is one member of the AT91SAM7S256 family which is designed as the low pincount Flash microcontroller that includes a reset controller capable of managing the power-on sequence of the microcontroller and the complete system. And this device can be programmed in-system via the JTAG-ICE interface or via a parallel interface on a production programmer prior to mounting.

Features of the AT91SAM7S256-AU are:(1)Thirty-two or twenty-one Programmable I/O Lines Multiplexed with up to Two Peripheral I/Os;(2)Input Change Interrupt Capability on Each I/O Line;(3)Individually Programmable Open-drain, Pull-up resistor and Synchronous Output;(4)On-chip Transceiver, 328-byte Configurable Integrated FIFOs;(5)Independent Clock and Frame Sync Signals for Each Receiver and Transmitter;(6)High-speed Continuous Data Stream Capabilities with 32-bit Data Transfer;(7)Support for ISO7816 T0/T1 Smart Card, Hardware Handshaking, RS485 Support;(8)Manchester Encoder/Decoder;(9)Full Modem Line Support on USART1;(10)IEEE 1149.1 JTAG Boundary Scan on All Digital Pins.
