* [[Microchip Technology|Microchip]] (formerly Atmel) manufactured TPM devices that it claims to be compliant to the Trusted Platform Module specification version 1.2 revision 116 and offered with several interfaces (LPC, SPI, and I<sup>2</sup>C), modes (FIPS 140-2 certified and standard mode), temperature grades (commercial and industrial), and packages (TSSOP and QFN).<ref name="AtmelTPMFrontPage">{{cite web|url=http://www.atmel.com/products/security-ics/embedded/|title=Home – Microchip Technology|website=www.atmel.com|access-date=October 4, 2016|archive-date=October 5, 2016|archive-url=https://web.archive.org/web/20161005162507/http://www.atmel.com/products/security-ics/embedded/|url-status=dead}}</ref><ref>{{cite web|url=http://www.atmel.com/Images/Atmel-8965-TPM-Part-No-Selection-Guide-ApplicationNote.pdf|title=AN_8965 TPM Part Number Selection Guide – Application Notes – Microchip Technology Inc.|website=www.atmel.com|access-date=October 4, 2016|archive-date=October 5, 2016|archive-url=https://web.archive.org/web/20161005171009/http://www.atmel.com/Images/Atmel-8965-TPM-Part-No-Selection-Guide-ApplicationNote.pdf|url-status=dead}}</ref><ref>{{cite web |url=https://www.microchip.com/en-us/products/security/security-ics/tpm |title="Trusted Platform Module" |author=<!--Not stated--> |date= |website= |publisher=Microchip Technology |access-date=2024-02-14 |quote=}}</ref> Its TPMs support PCs and embedded devices.<ref name="AtmelTPMFrontPage"/> It also provides TPM development kits to support integration of its TPM devices into various embedded designs.<ref>{{cite web|url=http://www.atmel.com/products/security-ics/embedded/?tab=tools|title=Home – Microchip Technology|website=www.atmel.com|access-date=October 4, 2016|archive-date=October 5, 2016|archive-url=https://web.archive.org/web/20161005165740/http://www.atmel.com/products/security-ics/embedded/?tab=tools|url-status=dead}}</ref>
* [[Nuvoton]] Technology Corporation provides TPM devices for PC applications. Nuvoton also provides TPM devices for embedded systems and Internet of Things (IoT) applications via I<sup>2</sup>C and SPI host interfaces. Nuvoton's TPM complies with [[Common Criteria]] (CC) with assurance level EAL 4 augmented with ALC_FLR.1, AVA_VAN.4 and ALC_DVS.2, [[FIPS 140-2]] level 2 with Physical Security and EMI/EMC level 3 and [[Trusted Computing Group]] Compliance requirements, all supported within a single device. TPMs produced by [[Winbond]] are now part of Nuvoton.<ref>{{cite web | url = https://www.nuvoton.com/products/cloud-computing/security/trusted-platform-module-tpm | title = Nuvoton TPM}}</ref>
* [[STMicroelectronics]] has provided TPMs for PC platforms and embedded systems since 2005. The product offering <ref>{{cite web | url = https://www.st.com/content/ccc/resource/sales_and_marketing/promotional_material/flyer/group0/62/f7/89/67/99/9a/40/45/STSAFE_TPM_Flyer/files/STSAFE-TPM-Flyer.pdf/jcr:content/translations/en.STSAFE-TPM-Flyer.pdf | title = STSAFE-TPM}}</ref> includes discrete devices with several interfaces supporting [[Serial Peripheral Interface]] (SPI) and [[I2C|I<sup>2</sup>C]] and different qualification grades (consumer, industrial and automotive). The TPM products are [[Common Criteria]] (CC) certified EAL4+ augmented with ALC_FLR.1 and AVA_VAN.5, [[FIPS 140-2]] level 2 certified with physical security level 3 and also [[Trusted Computing Group]] (TCG) certified.
 
There are also hybrid types; for example, TPM can be integrated into an [[Ethernet]] controller, thus eliminating the need for a separate motherboard component.<ref>{{cite web | url = https://www.trustedcomputinggroup.org/files/temp/4B551C9F-1D09-3519-AD45C1F0B5D61714/TPM%20Overview.pdf | title = Replacing Vulnerable Software with Secure Hardware: The Trusted Platform Module (TPM) and How to Use It in the Enterprise | year = 2008 | access-date = June 7, 2014 | publisher = Trusted computing group | archive-date = July 14, 2014 | archive-url = https://web.archive.org/web/20140714233816/https://www.trustedcomputinggroup.org/files/temp/4B551C9F-1D09-3519-AD45C1F0B5D61714/TPM%20Overview.pdf | url-status = live }}</ref><ref>{{cite web | url = http://www.broadcom.com/products/Ethernet-Controllers-and-Adapters/Enterprise-Client-Controllers/BCM5752 | title = NetXtreme Gigabit Ethernet Controller with Integrated TPM1.2 for Desktops | date = May 6, 2009 | access-date = June 7, 2014 | publisher = Broadcom | archive-date = June 14, 2014 | archive-url = https://web.archive.org/web/20140614134124/http://www.broadcom.com/products/Ethernet-Controllers-and-Adapters/Enterprise-Client-Controllers/BCM5752 | url-status = live }}</ref>
