Description
The AT91SAM7A3 is a member of a series of 32-bit ARM7
microcontrollers with an integrated
CAN controller. It features a 256-Kbyte high-speed Flash and 32-Kbyte SRAM, a large set of
peripherals, including two 2.0B full CAN controllers, and a complete set of system functions min-
imizing the number of external components. The device is an ideal migration path for 8-bit
microcontroller users looking for additional performance and extended memory.
The embedded Flash memory can be programmed in-system via the JTAG-ICE interface. Built-
in lock bits protect the firmware from accidental overwrite.
The AT91SAM7A3 integrates a complete set of features facilitating debug, including a JTAG
Embedded ICE interface, misalignment detector, interrupt driven debug communication channel
for user configurable trace on a console, and JTAG boundary scan for board level debug and
test.
By combining a high-performance 32-bit RISC processor with a high-density 16-bit instruction
set, Flash and SRAM memory, a wide range of peripherals including CAN controllers, 10-bit
ADC, Timers and serial communication channels, on a monolithic chip, the AT91SAM7A3 is
ideal for many compute-intensive embedded control applications.
