AT97SC3205-G3M45-10

Overview

The AT97SC3205-G3M45-10 is a Trusted Platform Module (TPM) 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 with clock frequencies up to 45MHz. It includes a FIPS-140-2 certified high-quality Random Number Generator (RNG), HMAC, AES, SHA, and RSA engines. The component operates on a 3.3V supply voltage and provides 2066 bytes of non-volatile user-defined data storage.

Procurement Notes

Verify the specific ordering suffix against the official Atmel Ordering Code table in the datasheet addendum. Confirm package type availability, as the standard catalog lists 28X1 (TSSOP) and 32M3 (QFN). Ensure the selected variant matches the required operating temperature range for the target application environment.

Selection Notes

Select based on the required package format: 28-lead Thin TSSOP or 32-pad QFN. Verify that the system design accommodates the 3.3V supply voltage requirement. Ensure the host controller supports the SPI protocol and can handle the specified clock frequency limits. Check if the commercial or industrial temperature range meets the deployment conditions.

Part Context

The AT97SC3205 series serves as a single-chip turnkey solution for OEMs and ODMs integrating security features into PC clients and embedded devices. It combines firmware, drivers, and manufacturing support software to facilitate board assembly initialization and verification processes.

Replacement Considerations

Consult the AT97SC3205 Summary Part Number Selection Guide for verified substitutes. Ensure any replacement maintains compatibility with TCG TPM 1.2 specifications and the specific SPI pinout configuration.
