Product details

Overview

SC-KTPM-RASPIZA9 from STMicroelectronics is an evaluation board designed to interface the ST33KTPM2I3WBZA9 industrial-grade Trusted Platform Module (TPM 2.0) with Raspberry Pi® and STM32MPx-DK development platforms. It supports configurable I²C or SPI communication, features a dedicated TPM reset button, includes a 26-pin female header for Raspberry Pi®/STM32MPx-DK connection, and provides on-board signal marking and power consumption measurement capability via R4 (10 Ω).

For engineers reviewing the SC-KTPM-RASPIZA9 datasheet, SC-KTPM-RASPIZA9 pinout, SC-KTPM-RASPIZA9 application, or SC-KTPM-RASPIZA9 equivalent, this board enables rapid validation of TPM integration in Linux-based embedded systems - especially where industrial temperature range (-40°C to +85°C), firmware version 10.257, and TCG TPM 2.0 specification 1.59 compliance are required.

Technical Context

The SC-KTPM-RASPIZA9 implements a hardware-validated bridge between STSAFE-TPM devices and host platforms, supporting dual-bus selection (I²C/SPI) through GPIO15 (GPI_I2C_SELECT) and configurable chip select (CS0/CS1) for multi-slave SPI environments. It routes all critical TPM signals - including RST (active-low), PP (physical presence), PIRQ (interrupt), SDA/SCL, and MOSI/MISO/SCLK - with PCB-level labeling for probing and debug.

It integrates a pre-soldered ST33KTPM2I3WBZA9 QFN32 TPM device, compliant with industrial temperature grade and certified to TCG TPM 2.0 spec 1.59. The board supports Linux® kernel TPM drivers (TCG-TPM-I2C-DRV) across versions 5.4–6.1+, and is validated with X-LINUX-TPM Yocto layer for STM32MP1xx platforms.

Key Specifications

Parameter	Value and Actual Design Meaning
Supported TPM Device	ST33KTPM2I3WBZA9 - industrial-grade TPM 2.0 module with firmware v10.257 and -40°C to +85°C operation.
Host Interface Options	I²C (SDA/SCL) or SPI (MOSI/MISO/SCLK/CS0/CS1) - selected via jumper or optional slide switch on GPI_I2C_SELECT (GPIO15).
Physical Connectors	26-pin female header (Raspberry Pi®/STM32MPx-DK compatible) + 26-pin male header for probing or stacking extension boards.
TPM Reset Function	Dedicated mechanical push-button that asserts active-low RST without platform reboot - triggers TPM_Init per PTP standard.

FAQ

Does SC-KTPM-RASPIZA9 support both Raspberry Pi® and STM32MPx-DK platforms?

Yes - it connects directly to the 40-pin GPIO header of Raspberry Pi® 3/4/5 and STM32MP135F-DK / STM32MP157F-DK2 via its 26-pin female header. Mechanical design accommodates all three platforms without interference, and signal routing matches their respective GPIO definitions for I²C and SPI interfaces.

How is bus interface selection implemented on SC-KTPM-RASPIZA9?

Bus selection is controlled by GPI_I2C_SELECT (GPIO15): pulled low for I²C mode (SDA/SCL), pulled high for SPI mode (MOSI/MISO/SCLK/CS). A solderable jumper or optional slide switch configures this signal. Default configuration uses a jumper; the slide switch is an alternative for frequent switching during development.

What Linux® kernel versions and drivers are supported for TPM activation?

SC-KTPM-RASPIZA9 supports Linux® kernels 5.4 through 6.1+ using the upstream TCG-TPM-I2C-DRV driver. For STM32MP1xx platforms, X-LINUX-TPM Yocto layer provides full integration, including TPM2_Startup, TPM2_SelfTest, and attestation workflows documented in AN5714.

Is the ST33KTPM2I3WBZA9 TPM device pre-soldered on SC-KTPM-RASPIZA9?

Yes - each SC-KTPM-RASPIZA9 board ships with the ST33KTPM2I3WBZA9 industrial-grade TPM device already soldered in QFN32 package. This device implements TCG TPM 2.0 specification 1.59, firmware version 10.257, and operates across -40°C to +85°C ambient temperature.
