Waveshare FT245 FT245RL USB to FIFO Module Communication Development Board Mini/Type-A interface

Feature
1. FT245RL
USB independent chip for parallel FIFO bidirectional data transmission interface
Complete USB protocol processing chip-no specific USB firmware programming required
Based on 4-wire handshake connection, simple interface for MCU/PLD/FPGA logic
Data transfer rate up to 1 Megabyte/second-D2XX Direct Drivers
Data transfer rate up to 300kilobyte/second-VCP Drivers
256-byte receive buffer and 128-byte send buffer, using buffer smoothing technology to achieve high data throughput
2. USB interface
Provide two types of mini USB and type A USB interfaces to choose from
3. VCCIO power supply jumper
The jumper cap can be used to jump to VCCIO to access 5V or 3.3V voltage (VCCIO can be used to supply power to the VCC pin of the access board)
4. Power indicator
Module power indicator, easy to check the power supply status of the module
5. Interface
Connect to the corresponding interface of the single chip microcomputer

Description
VCCIO
Power supply
It can be used to supply the FT245 chip or power to external devices, and can be set to 3.3V or 5V through the VCCIO jumper
GND
Power supply
Power ground
D0~D7
Input Output
FIFO data bus bits 0~7
NC
NC
Dangling
RST
Input
Used to reset FT245
PWREN
Output
After the USB configuration is successful, it is set low, and is pulled high when the USB is terminated
TXF
Output
Does not write to FIFO when pulled high, data can be written to FIFO when TXF is pulled low, and WR is pulled high
RXF
Output
Does not read FIFO when pulled high, when RXF is pulled low, and RD is pulled low, valid data of FIFO can be read
WR
Input
Write to FIFO when pulled low
RD
Input
Read FIFO when pulled low
Package includes
1 x FT245 USB FIFO Board
