AT97SC3205T-G3M4C-10

Application Specific Microcontrollers Overview

The AT97SC3205T-G3M4C-10 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 key storage. The device supports I2C communication at 100kHz Standard Mode and 400kHz Fast Mode. It operates on a 3.3V supply voltage and includes a FIPS-140-2 certified high-quality Random Number Generator (RNG). 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. Ensure decoupling capacitors are placed within 5mm of VCC pins using X5R or X7R dielectrics for reliable operation.

Application Specific Microcontrollers Selection Notes

Select the appropriate package based on board space constraints; the 32-pin QFN measures 4.00mm x 4.00mm while the 28-pin TSSOP measures 4.40mm x 9.70mm. Consider pull-up resistor values for I2C stability, specifically 800Ω on SM_DAT and 1.5KΩ on SM_CLK for 400kHz operation. Verify GPIO pin configurations if utilizing physical presence indicators or low-power sleep recovery features.

Application Specific Microcontrollers Part Context

This component belongs to the AT97SC3205T series of security ICs designed by Microchip Technology (formerly Atmel). It serves as a single-chip turnkey solution for implementing trusted computing standards in embedded environments. The device replaces discrete security components by integrating cryptographic engines, RNG, and non-volatile memory into one package.

Application Specific Microcontrollers Replacement Considerations

Check for updated revisions within the AT97SC3205T family that may offer different packaging or temperature ratings. Verify compatibility with existing firmware if migrating between package types due to pin configuration differences.
