GC-TPM2.0 – 20-1 Pin LPC TPM 2.0 Module

GC-TPM2.0 – 20-1 Pin LPC TPM 2.0 Module – Discrete Hardware Security

Discrete TPM 2.0 add-in card for boards that use the 20-1 pin LPC “TPM” header (standard desktop/server LPC header). This is the standard GC-TPM2.0, not the GC-TPM2.0_S SPI version.

Description

The module plugs directly into a motherboard’s LPC TPM (20-1 pin) header and provides a hardware root-of-trust for BitLocker, Secure Boot, measured boot, and platform attestation. Ideal for systems that require a removable, discrete TPM rather than firmware TPM (PTT/fTPM) or the SPI-header variant.

Technical Specifications

• Model / PN: GC-TPM2.0 (standard LPC version)
• TPM Standard: 2.0 (TCG Family 2.0)
• Header Type: LPC TPM, 20-1 pin keyed header (2×10 with one missing pin)
• Interface/Bus: LPC (discrete TPM)
• Form Factor: Small vertical daughtercard, direct plug-in
• Functions: Secure key storage, RNG, PCR/attestation, measured boot
• Firmware/OS: UEFI systems with support for discrete TPM; enable in BIOS/UEFI
• Typical Uses: BitLocker/Device Encryption, Secure Boot, hardware identity and compliance

Interchangeable / Replacement Part Numbers

• GC-TPM2.0 (LPC 20-1 pin version)

✅ Confirmed Compatibility

Please note that the following list is not exhaustive. Compatibility depends on your system’s specific configuration. It’s essential to verify compatibility with your system or enclosure manufacturer prior to installation.

✔️ Motherboards featuring a 20-1 pin LPC header labeled “TPM”
✔️ Platforms documented to accept an LPC (20-1) TPM 2.0 module
✔️ Systems that require a discrete TPM 2.0 device for security/compliance features

☑️ Key Features

• ☑️ Hardware root-of-trust for encryption keys and credentials
• ☑️ Direct 20-1 pin plug-in—no cables required
• ☑️ TPM 2.0 support for BitLocker, Device Security, Secure Boot workflows
• ☑️ Compact, low-power design for desktops and servers

⚙️ Fit Notes

• This is the LPC 20-1 pin version. It is not compatible with GC-TPM2.0_S (SPI 12-1 pin), ASUS TPM-SPI (14-1 SPI), or 14-1 LPC modules used by other vendors.
• Observe Pin-1 orientation when installing; never force insertion.
• In BIOS/UEFI, enable Discrete/External TPM (and disable PTT/fTPM if your board requires choosing one path).
• If moving the module to another system, clear/initialize the TPM in firmware before enabling BitLocker or similar features.
