AT97SC3205T-G3M4C-00

Application Specific Microcontrollers Overview

The AT97SC3205T-G3M4C-00 is a Trusted Platform Module (TPM) compliant with the TCG TPM Version 1.2 specification. It integrates an Atmel AVR RISC microprocessor, hardware asymmetric crypto engine, and internal EEPROM for RSA keys. The device operates at 3.3V via I2C interface supporting 400kHz Fast Mode or 100kHz Standard Mode. It includes FIPS-140-2 certified modules for RNG, HMAC, AES, SHA, and RSA. The component provides 2066 bytes of NV storage for user-defined data and is available in 28-lead Thin TSSOP or 32-pad QFN packages.

Application Specific Microcontrollers Procurement Notes

Verify package type availability as the component is offered in both 28-lead Thin TSSOP and 32-pad QFN configurations. Confirm operational temperature range requirements against commercial (0°C to 70°C) and industrial (-40°C to 85°C) options before procurement.

Application Specific Microcontrollers Selection Notes

Select based on required package footprint; 28X1 denotes 28-pin Thin TSSOP while 32M3 indicates 32-pin Very Thin QFN. Ensure supply voltage matches the specified 3.3V requirement. Verify that the host system supports the necessary I2C pull-up values (e.g., 800Ω for SM_DAT, 1.5KΩ for SM_CLK) for stable 400kHz communication.

Application Specific Microcontrollers Part Context

This part belongs to the AT97SC3205T series of security ICs manufactured by Microchip Technology (formerly Atmel). It serves as a single-chip turnkey solution for implementing trusted platform functionalities within embedded systems without requiring external cryptographic components.

Application Specific Microcontrollers Replacement Considerations

Consult the AT97SC3205T Summary Part Number Selection Guide for alternative ordering codes. Consider package variations such as 28X1 (TSSOP) or 32M3 (QFN) if pin compatibility allows. Verify firmware command set compatibility when substituting with other TPM versions.
