Product details
Overview
SLB9665TT20FW563XUMA3 from Infineon is a TPM 2.0 Trusted Platform Module compliant with TCG specification Level 00, Revision 01.16, featuring LPC interface, SHA-1/SHA-256 PCR support (24 PCRs), 7206 Byte NV memory, and low standby current (150 µA typ.). It serves as a hardware root-of-trust for platform authentication in desktop, notebook, and embedded security applications.
For engineers reviewing the SLB9665TT20FW563XUMA3 datasheet, SLB9665TT20FW563XUMA3 pinout, SLB9665TT20FW563XUMA3 application, or SLB9665TT20FW563XUMA3 equivalent, key selection factors include LPC bus timing compliance, EK personalization capability, NIST SP800-90A RNG certification, and TSSOP-28 thermal range (-20°C to +85°C).
Technical Context
The SLB9665TT20FW563XUMA3 implements a dedicated TPM 2.0 state machine with locality-based register access over LPC, supporting only TPM-type read/write cycles-not legacy IO-mapped accesses. Its internal power management automatically transitions to low-power idle mode within 50 ms after command completion, without requiring external LPCPD or CLKRUN signals.
It integrates a FIPS-compliant RNG per NIST SP800-90A, supports up to 3 loaded transient objects and 7 persistent objects, and provides 1280 Byte I/O buffer with configurable SHA-1 or SHA-256 PCR algorithms-enabling secure boot measurement, attestation, and sealed storage in Intel TXT and Windows-certified platforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Interface | LPC bus only; supports TPM-type cycles only-no legacy IO cycles or LPCPD/CLKRUN control. |
| PCRs | 24 Platform Configuration Registers, configurable for SHA-1 or SHA-256 hashing-used for measured boot integrity verification. |
| NV Memory | 7206 Bytes of non-volatile storage-holds keys, certificates, policies, and sealed data persistently across reboots. |
| Standby Current | 150 µA typical-enables long-term operation in battery-backed or always-on security subsystems. |
| Operating Temp | -20°C to +85°C-validated for standard industrial and client computing environments. |
| RNG Compliance | Fully compliant with NIST SP800-90A-provides cryptographically secure entropy for key generation and challenge-response protocols. |
| I/O Buffer | 1280 Byte internal buffer-supports full TPM 2.0 command/response framing including parameter marshaling and error handling. |
Pinout & Package
SLB9665TT20FW563XUMA3 uses the PG-TSSOP-28-2 package (28-pin thin shrink small outline package), with 0.65 mm pitch, 9.7 mm × 4.4 mm body, and exposed thermal pad. Pin functions are defined per Infineon's Figure 1 (Data Sheet Rev 1.2, p.9).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LRESET# | Active-low reset input | Asynchronous hardware reset; initiates full TPM state initialization and clears volatile session context. |
| LCLK | LPC clock input | Accepts 33 MHz LPC clock; synchronizes all register accesses and command execution timing. |
| LFRAME# | LPC frame start signal | Indicates start of LPC cycle; required for locality arbitration and transaction boundary detection. |
| LAD[3:0] | LPC address/data multiplexed bus | Carries both address (during SYNC phase) and data (during DATA phase); requires external latching logic. |
| LDRQ# | Host DMA request | Not used by SLB9665-device operates exclusively in programmed I/O mode; pin must be pulled high. |
| VDD / VDDIO | Power supply | 3.3 V ±10% core and I/O supply; decoupling capacitor (100 nF) required per pin per datasheet layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| TPM 2.0 Certification | Fully compliant with TCG Main Specification v1.16 Level 00-qualified for Microsoft Windows, Google Chromebook, and Intel TXT platform attestation. |
| Endorsement Key (EK) | Factory-provisioned, non-exportable RSA-2048 EK with X.509 certificate-enables platform identity binding and remote attestation. |
| Secure Session Management | Supports up to 64 active sessions and 3 concurrently loaded sessions-enables concurrent policy evaluation and multi-application access control. |
| Command Parameter Limits | Up to 1 kByte for command/response parameters and 768 Byte for NV read/write-enables large key import/export and policy blob handling. |
| Linux Kernel Integration | Built-in support starting with Linux Kernel v3.10-enables direct tpm_tis driver usage without firmware or HAL layer abstraction. |
Applications
| Desktop Platform Security | Industrial Embedded Control |
|---|---|
Use Scenario: Secure boot chain enforcement on x86 desktop motherboards with UEFI firmware. IC Role / Device Role / Timing Role: Hardware root-of-trust that measures firmware, bootloader, and OS kernel into PCRs before execution. Use Value: Prevents unauthorized firmware modification by validating hash chains against pre-provisioned policies stored in NV memory. | Use Scenario: Remote firmware update authentication in programmable logic controllers (PLCs) with cellular backhaul. IC Role / Device Role / Timing Role: Cryptographic anchor for verifying signed firmware images prior to flash programming. Use Value: Ensures only OEM-signed updates execute, mitigating supply-chain compromise via tamper-proof signature validation using EK-bound keys. |
| Thin Client Authentication | Medical Device Data Integrity |
Use Scenario: Credential protection in zero-client thin terminals accessing cloud-hosted virtual desktops. IC Role / Device Role / Timing Role: Secure credential store for TLS client certificates and smart card emulation keys. Use Value: Isolates private keys from OS memory, preventing extraction during runtime or memory dump attacks. | Use Scenario: Audit log sealing in FDA-cleared diagnostic imaging systems (e.g., ultrasound, MRI controllers). IC Role / Device Role / Timing Role: Tamper-evident timestamped log recorder using HMAC-SHA256 with persistent NV counters. Use Value: Provides cryptographic proof of log integrity and sequence continuity for regulatory compliance (21 CFR Part 11). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TPM 2.0 security module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SLB9670TT20FW563XUMA1 | Same TSSOP-28 package but with extended temperature range (-40°C to +85°C) and updated firmware revision. | Required for outdoor or automotive-adjacent industrial deployments where ambient exceeds +85°C derating limits. | Select when operating environment exceeds SLB9665TT20FW563XUMA3's -20°C to +85°C spec. |
| ST33TPHF2ESPI | Uses SPI interface instead of LPC; supports same TPM 2.0 features but different host bus protocol and timing constraints. | Suitable for ARM-based SoC platforms lacking native LPC bus, such as Raspberry Pi CM4 or NXP i.MX8 designs. | Choose for SPI-native hosts; requires redesign of host driver and board-level routing. |
Compared with SLB9665TT20FW563XUMA3, SLB9670TT20FW563XUMA1 extends thermal tolerance without changing pinout or firmware API, while ST33TPHF2ESPI replaces LPC with SPI-introducing interface-level incompatibility but enabling broader SoC integration.

FAQ
Is SLB9665TT20FW563XUMA3 pin-compatible with SLB9660?
Yes, SLB9665TT20FW563XUMA3 is explicitly pin-compatible with SLB9660 per Infineon's datasheet Section 2 (Device Types / Ordering Information). This enables drop-in replacement in existing LPC-based designs without PCB revision, provided firmware supports TPM 2.0 command set extensions.
Does this device support SHA-256 PCR banks?
Yes, SLB9665TT20FW563XUMA3 supports 24 PCRs configurable for either SHA-1 or SHA-256 hashing per TCG specification. PCR bank selection is controlled via TPM2_SetAlgorithmSet command and persists across power cycles in NV memory.
What is the maximum allowed LPC clock frequency?
The maximum supported LPC clock frequency is 33 MHz, as specified in Section 4.4 (AC Characteristics) and Table 12 of the datasheet. Operation above this frequency violates timing margins and may cause command corruption or SYNC aborts.
Can the Endorsement Key be regenerated or replaced?
No-the Endorsement Key is factory-provisioned, fused, and non-exportable. It cannot be regenerated, replaced, or extracted. The associated EK certificate is pre-loaded and bound to the device's unique identifier, forming the immutable root for all attestation chains.
