AT97SC3205-U3A15-10

Application Specific Microcontrollers Overview

The AT97SC3205-U3A15-10 is a Trusted Platform Module (TPM) security IC compliant with TCG TPM Version 1.2 and TIS Version 1.3 specifications. It integrates an Atmel AVR RISC microprocessor, hardware asymmetric crypto engine, and internal EEPROM for RSA key storage. The device supports the Serial Peripheral Interface (SPI) protocol at frequencies up to 45MHz. It includes a FIPS-140-2 certified Random Number Generator (RNG), HMAC, AES, SHA, and RSA engines, along with 2066 bytes of non-volatile user-defined data storage. Operating on a 3.3V supply, it is available in commercial and industrial temperature ranges.

Application Specific Microcontrollers Procurement Notes

Verify the specific package type required for the design, as the AT97SC3205 family is offered in both 28-lead thin TSSOP and 32-pad QFN packages. Confirm that the selected variant meets the necessary operating temperature range for the target application environment before finalizing procurement.

Application Specific Microcontrollers Selection Notes

Select the appropriate package based on board space constraints; the 28X1 denotes a 28-lead thin TSSOP while the 32M3 indicates a 32-pad very thin QFN. Ensure the system operates within the specified voltage range and that SPI clock speeds remain within the typical PC operating range of 24MHz to 33MHz for optimal performance.

Application Specific Microcontrollers Part Context

The AT97SC3205 series serves as a single-chip turnkey solution for implementing Trusted Platform Modules. Originally developed by Atmel Corporation, these devices provide integrated firmware and hardware security features designed for seamless integration into personal computer architectures and other embedded systems requiring trusted computing capabilities.

Application Specific Microcontrollers Replacement Considerations

Consult Microchip Technology for current equivalent components or updated series replacements, as Atmel has been acquired by Microchip. Verify pin compatibility and firmware support when transitioning from legacy Atmel-sourced parts to ensure continued compliance with TCG specifications.
