AT91SC512384-8M Datasheet, PDF (2/3 Pages) ATMEL Corporation – 32-bit Secure Microcontrollers

Description
The AT91SC512384-8M is a dual chip solution, binding the AT91SC512384RCT device to the
AT45DB642D Data Flash memory.
The AT91SC512384RCT is a Secure Microcontroller, low-power, high-performance, 32-bit RISC
microcontroller with ROM program memory, internal EEPROM data memory, and cryptographic
accelerator, based on the ARM SC100 advanced secure processor. This general-purpose 32-bit
processor offers high performance, very low power consumption, and additional features to help
combat fraud.
The AT45DB642D is a Flexible, Low-Cost Serial Flash solution. It features 8M Bytes of Flash memory
and 2 x 1056 Bytes SRAM buffers.
The AT91SC512384-8M is delivered in an ISO7816-2 micro module package with necessary drivers to
manage all its peripherals.

Overview
The AT91SC512384RCT secure microprocessor is attached to the AT45DB642D device thru an
interface providing:
• Power supply to the Flash memory, whatever external Vcc delivered
• Serial Peripheral Interface Bus for data transfer between the two devices and control on
Flash memory
SPI features are Industry standard bus, Full Duplex communication and reduced physical connections.
SPI master is the AT91SC512384RCT device and slave is the AT45DB642D device.
