What are the key features of ST33GTPMII2C?
- TPM 2.0 compliant flash-based security controller with hardware-rooted root-of-trust, supporting RSA-2048 and ECC-256 cryptographic algorithms for industrial embedded systems
- I2C interface at up to 400 kHz (Fast Mode) enables simple 2-wire integration with microcontrollers and SoCs without additional bus infrastructure
- Ultra-compact WLCSP-11 package measuring approximately 1.7 x 2.0 mm allows TPM security in space-constrained industrial IoT and embedded computing designs
What is ST33GTPMII2C used for?
The ST33GTPMII2C is designed for industrial IoT gateways, embedded computing modules, and network appliances that require hardware-enforced TPM 2.0 security with a minimal footprint. It stores cryptographic keys, certificates, and platform integrity measurements in on-chip flash memory, protecting firmware from tampering in systems operating across -40°C to +85°C industrial temperature ranges. Its I2C interface and WLCSP-11 package make it straightforward to integrate into space-constrained designs alongside application processors running Linux or RTOS-based secure boot chains.

Frequently Asked Questions
What cryptographic algorithms does the ST33GTPMII2C support under TPM 2.0?
The ST33GTPMII2C supports RSA-2048, ECC-256 (NIST P-256), SHA-256, and AES-128 algorithms as part of its TPM 2.0 implementation. These provide hardware-accelerated signing, key generation, and symmetric encryption, delivering secure boot and remote attestation for industrial embedded designs operating from 1.8 V supply rails.
How does the I2C interface of the ST33GTPMII2C simplify integration compared to SPI-based TPM devices?
The I2C interface operates at up to 400 kHz in Fast Mode and requires only 2 signal wires (SDA and SCL), eliminating the need for dedicated chip-select or SPI bus arbitration logic. This reduces the pin count impact on the host microcontroller to just 2 GPIO pins, saving PCB routing space in designs where the SPI bus is already allocated to flash or display peripherals.
Which industrial temperature range and package does the ST33GTPMII2C support?
The ST33GTPMII2C is rated for an industrial temperature range of -40°C to +85°C and is housed in an 11-ball WLCSP package measuring approximately 1.7 x 2.0 mm with a 0.5 mm ball pitch, making it one of the smallest available hardware TPM solutions for industrial PCB designs.
When would an industrial IoT design choose the ST33GTPMII2C over a discrete secure element?
When a design requires standards-compliant TPM 2.0 attestation recognized by Windows, Linux, and industrial IEC 62443 frameworks, the ST33GTPMII2C is preferred over proprietary secure elements because it delivers full TPM 2.0 command sets including platform configuration registers (PCRs) and sealed storage for 2 KB of non-volatile data, without requiring a custom host-side security stack.
