SLB9665VQ20FW560XUMA2

Application Specific Microcontrollers Overview

The SLB9665VQ20FW560XUMA2 is an Infineon OPTIGA™ TPM 2.0 security controller compliant with TCG Family '2.0', Level 00, Revision 01.16. It utilizes a Low Pin Count (LPC) interface and operates within a supply voltage range of 3.0 V to 3.6 V. The device provides 7206 bytes of free non-volatile memory and supports 24 Platform Configuration Registers (PCRs) using SHA-1 or SHA-256 algorithms. Designed for standard temperature applications (-20°C to +85°C), it features a PG-VQFN-32-13 package. Key capabilities include NIST SP800-90A-compliant random number generation, full personalization with Endorsement Keys, and optimized low standby power consumption of approximately 150 µA.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current availability documentation, as product status may change. Confirm that the PG-VQFN-32-13 package aligns with PCB footprint requirements. Ensure the standard temperature range (-20°C to +85°C) meets environmental specifications. Cross-reference the firmware version indicated in the part marking during assembly.

Application Specific Microcontrollers Selection Notes

Select this model for designs requiring a pin-compatible upgrade from the SLB 9660 series while adhering to TPM 2.0 standards. The VQFN package is suitable for space-constrained layouts compared to the TSSOP variant. Verify that the host system supports LPC TPM-type cycles rather than standard IO-mapped addressing. Ensure the design accommodates the required 100 nF bypass capacitors near all VDD pins.

Application Specific Microcontrollers Part Context

This component belongs to the OPTIGA™ TPM SLB 9665 family, which also includes the SLB 9665TT2.0 (TSSOP-28), SLB 9665XQ2.0 (Enhanced Temp VQFN), and SLB 9665XT2.0 (Enhanced Temp TSSOP). The 'VQ' designation specifically identifies the PG-VQFN-32-13 package with the standard industrial temperature range. All variants share identical functional specifications and LPC interfaces.

Application Specific Microcontrollers Replacement Considerations

The SLB 9665TT2.0 serves as a pin-compatible alternative if a TSSOP-28 package is preferred over the VQFN-32 form factor. For enhanced temperature operation (-40°C to +85°C), the SLB 9665XQ2.0 is the direct equivalent in the same package. Ensure any replacement maintains compatibility with the host's LPC signaling and power management constraints.
