ATTPM20P-G3MA1-10

Specialized ICS Overview

The ATTPM20P-G3MA1-10 is a Trusted Platform Module (TPM) 2.0 security cryptoprocessor from Microchip Technology, designed for integration into personal computers, embedded systems, and IoT platforms. It implements the TCG TPM Version 2.0 r116 specification via an SPI interface operating up to 36 MHz. The device features a hardware asymmetric crypto engine supporting HMAC, AES-128, SHA-1/SHA-256, ECC BN_P256/NIST_P256, and RSA 1024-2048 bit keys. It includes 16 KB of user-accessible nonvolatile memory and pre-generated endorsement keys. Packaged in an 8-pad UDFN (2x3 mm), it operates within a commercial temperature range of 0°C to +70°C with a 1.8V to 3.3V supply voltage.

Specialized ICS Procurement Notes

Verify that the ordering suffix G3 corresponds to the commercial temperature range (0°C to +70°C). Confirm the MA1 package code matches the required 8-pad UDFN footprint. Ensure the -10 suffix indicates the inclusion of pre-generated endorsement keys as specified in the Product Identification System documentation.

Specialized ICS Selection Notes

Select this component when a compact TPM 2.0 solution is required for commercial-grade applications. The G3 suffix designates the 0°C to +70°C operating range; use H3 for industrial temperatures (-40°C to +85°C). Verify system power supplies support the 1.8V to 3.3V input range and that the host controller supports the required SPI protocol.

Specialized ICS Part Context

The ATTPM20P series serves as a single-chip turnkey TPM 2.0 solution by Microchip Technology. It utilizes an ARM M0+ microprocessor and internal flash storage for keys. The device is designed to be FIPS-140-2 compliant and includes physical security measures such as voltage and temperature tamper detection.

Specialized ICS Replacement Considerations

For industrial temperature requirements (-40°C to +85°C), consider the ATTPM20P-H3MA1-10 variant which shares the same package and functionality but operates at 3.3V only.
