概要

Description

FT245RQ-REEL is FTDI’s RoHS-compliant version of the FT245R USB-to-parallel FIFO bridge, sold in tape-and-reel packaging for automated assembly. It provides an 8-bit bidirectional data bus (D0–D7) plus simple control/handshake lines and an integrated USB full-speed controller with an internal FIFO. The device lets a USB host exchange data with a parallel peripheral or microcontroller without an external USB microcontroller. It is supported by FTDI drivers (D2XX or VCP) for Windows/Linux/macOS. Common uses include data acquisition, instrumentation, and USB-to-parallel I/O bridging. The -REEL suffix denotes packaging (tape-and-reel); -RQ indicates RoHS-compliant material.

Features

Here are the key features of the FT245RQ-REEL (USB FIFO, 8-bit parallel I/O):
- USB 2.0 Full-Speed device (12 Mbps) with integrated transceiver; USB bus powered.
- 8-bit bidirectional data bus (D0–D7) for direct data exchange with a microcontroller.
- Internal USB-to-parallel FIFO bridge; no extra microcontroller needed for USB handling.
- WR# and RD# control lines to write to and read from the device; data flow governed by FIFO status.
- TXF and RXF status signals for simple flow control (transmit/receive FIFO flags).
- CBUS pins configurable as GPIO or LED drive (configurable I/O).
- Sleep/power-management support and USB suspend handling for low power.
- No external clock required; uses USB clocking (no external oscillator needed).
- RoHS-compliant; available on reel packaging for SMT assembly.
Notes:
- Designed for simple USB-to-parallel data transfer, compatible with FTDI’s FIFO mode and drivers.
- Suitable for microcontroller interfaces requiring a compact USB link without a full USB stack.

Package

SSOP-28 (28-pin Shrink Small Outline) in Tape & Reel packaging.

Pinout

- Pin count: 28 pins (28-pin package, reel packaging FT245RQ-REEL).
- Function: USB-to-parallel FIFO bridge. It provides an 8-bit bidirectional data bus (D0–D7) with simple control signals to transfer data between a USB host and a microcontroller/ASIC via a FIFO interface.

Manufacturer

Manufacturer: FTDI (Future Technology Devices International Ltd.).
What kind of company: A fabless semiconductor company based in the UK that designs and sells USB connectivity ICs, including USB-to-serial and USB FIFO bridge devices.

Application

FT245RQ-REEL is a USB-to-8‑bit parallel FIFO bridge. Typical applications:
- Data acquisition and logging
- USB interface to microcontrollers/embedded systems
- Interfacing ADC/DAC, sensors, and other 8‑bit peripherals
- PC-based instruments and test equipment
- Industrial automation and control panels
- Rapid prototyping and USB peripheral development
- General-purpose USB data transfer over an 8‑bit bus

Equivalent

FT245RQ-REEL is the RoHS version of FTDI’s FT245R USB-to-8‑bit parallel FIFO in tape‑and‑reel packaging. Closest equivalents in FTDI’s lineup are: FT245R (standard), FT245RQ (RoHS non‑REEL), and FT245RL (lead‑free). There isn’t an exact cross‑vendor 1:1 equivalent; packaging/RoHS status are the main differences.
