FT120T-R

Controllers Overview

The FT120T-R is a USB device controller from the FT120 series, manufactured by FTDI. It integrates a Serial Interface Engine (SIE), endpoint buffer, transceiver, and voltage regulators into a single chip. The component supports USB 2.0 Full Speed and USB 1.1 protocols via an 8-bit parallel interface to external microcontrollers or FPGAs. It operates on a single power supply ranging from 3.3V to 5.5V, with internal LDOs for 1.8V and 3.3V rails. Key electrical parameters include a maximum supply voltage of 5.5V, minimum supply voltage of 3.3V, and operating current of 5mA. The device functions within a temperature range of -40°C to +85°C and is housed in a 28-pin TSSOP package measuring 9.8mm x 4.4mm x 1.05mm.

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and tape/reel specifications. Ensure the procurement channel provides RoHS compliance documentation consistent with the FT120 series requirements. Cross-reference the part number with official distributor catalogs to validate authenticity and avoid counterfeit components.

Controllers Selection Notes

Select this component when an 8-bit parallel interface is required between a USB host and a microcontroller or FPGA. The FT120T-R is suitable for applications needing integrated power regulation and bus-powered operation support. Consider the 28-TSSOP package constraints and the -40°C to +85°C operating temperature range during PCB layout and thermal design.

Controllers Part Context

The FT120T-R belongs to the FT120 family of USB controllers designed as alternatives to legacy D12 chips. This series focuses on providing a complete USB solution with minimal external components. The 'T' indicates the TSSOP package, while '-R' typically denotes reel packaging for surface-mount assembly.
