Infineon Technologies SLB9665TT20FW560XUMA2

Overview

SLB9665TT20FW560XUMA2 from Infineon is a TPM 2.0 Trusted Platform Module compliant with TCG Main Specification v01.16 Level 00, featuring LPC interface, SHA-1/SHA-256 PCR support (24 PCRs), 7206 Byte NV memory, and low standby current (150 µA typ.) for secure boot and platform attestation in x86-based industrial PCs and embedded systems.

For engineers reviewing the SLB9665TT20FW560XUMA2 datasheet, SLB9665TT20FW560XUMA2 pinout, SLB9665TT20FW560XUMA2 application, or SLB9665TT20FW560XUMA2 equivalent, key selection criteria include LPC timing compliance, EK personalization capability, NIST SP800-90A RNG certification, temperature range (-20°C to +85°C), and TSSOP-28 mechanical compatibility with legacy SLB9660 designs.

Technical Context

The SLB9665TT20FW560XUMA2 implements a dedicated hardware root of trust using a hardened ARM SecurCore SC300 CPU with on-die flash and tamper-resistant logic. It supports only TPM-type LPC cycles-not standard IO-mapped accesses-and enforces locality-based register access control per TCG specifications.

Power management is fully autonomous: the device wakes on LPC transaction start and returns to 150 µA standby mode 50 ms after command completion, without requiring external LPCPD or CLKRUN signals. All cryptographic operations-including SHA-256 hashing, RSA key generation, and HMAC signing-are executed internally with no host-side software dependency.

Key Specifications

Pinout & Package

SLB9665TT20FW560XUMA2 uses the PG-TSSOP-28-2 package: 28-pin, 0.65 mm pitch, body size 9.7 mm × 4.4 mm, exposed thermal pad (non-electrical), JEDEC MO-153 compliant.

FAQ

Does SLB9665TT20FW560XUMA2 support SPI interface?

No. This part exclusively implements the Low Pin Count (LPC) interface as defined in the TCG specification. It does not support SPI, I²C, or UART communication modes. Host systems must provide an LPC bus controller compatible with TPM 2.0 locality protocol timing and register mapping.

Is the Endorsement Key (EK) pre-provisioned and certified?

Yes. Each SLB9665TT20FW560XUMA2 unit ships with a unique, factory-generated RSA-2048 Endorsement Key permanently fused into secure memory, accompanied by an X.509 certificate signed by Infineon's Certificate Authority-enabling immediate use in attestation workflows without host-side key generation.

What is the maximum supported LPC clock frequency?

The device operates at a fixed 33 MHz LPC clock with ±1% tolerance, as specified in Table 12 of the datasheet. Exceeding this frequency violates AC timing parameters and may cause command aborts or data corruption; no overclocking or frequency scaling is supported.

Can this TPM be used in systems without ACPI support?

Yes. While ACPI facilitates automatic enumeration in Windows/Linux, the SLB9665TT20FW560XUMA2 functions correctly in non-ACPI environments via direct LPC I/O port access (0x0CF8–0x0CFF) and polling-based status register reads-common in bare-metal firmware and RTOS implementations.
