DFI TWLF51-EC-86X7213RE Intel Amston Lake Atom x7213RE Femto-ITX Single Board Computer with 8GB LPDDR5 Memory and -20 to 70 °C

Some control tasks are single-threaded and time-sensitive, so clock speed matters more than core count. The TWLF51-EC-86X7213RE targets that case in the DFI TWLF51 series: a 1.8″ Femto-ITX single board computer with two Amston Lake cores at a 2.0 GHz base clock, rated from -20 to 70 °C.

Its Intel Atom x7213RE runs two cores from 2.0 to 3.4 GHz at a 9 W TDP. Compared with the 6 W x7211RE, the higher base clock can give steadier performance under sustained load, for a little more heat. Memory is 8 GB of LPDDR5 at 4800 MHz and storage is 64 GB of eMMC, both soldered, with DFI listing in-band ECC (IBECC) support on the Amston Lake builds. Intel UHD Graphics drives HDMI 2.0 at up to 4096 x 2160 at 60 Hz.

Board I/O is one GbE port on an Intel I210-IT controller and two USB 3.2 Gen 2 Type-A ports at the edge, with two USB 2.0 ports, one RS-232/422/485 port and 8-bit DIO on internal headers. That covers a motion controller, a production test fixture or a vending controller talking to its peripherals over serial and digital lines. The M.2 E-key 2230 socket takes a Wi-Fi and Bluetooth module.

The TWLF51-EC-86X7213RE takes 12 V DC on a terminal block and operates from -20 to 70 °C, with Windows 11 IoT Enterprise or Linux support, a discrete TPM 2.0 and CE, FCC, UKCA and RoHS compliance. For the lowest power draw, the TWLF51-EC-86X72 runs its two cores at 6 W; for more parallel work, the TWLF51-EC-86X78 provides eight cores at 12 W.
