FT245 EVAL Board FT245R FT245RL USB TO Parallel FIFO Evaluation Development Kit
Evaluation Board Based on FT245, A High-performance Cost-effective Solution for USB TO 8-BIT FIFO
The FT245 EVAL BOARD provides a high-performance cost-effective solution for USB TO 8-BIT FIFO. It is based on the FT245RL chip and will hopefully allow to try out the full potential of the FT245 device before using it in your prototype.
The FT245RL is a USB to parallel FIFO interface device which simplifies USB to FIFO designs and reduces external component count by fully integrating an external EEPROM, USB termination resistors and an integrated clock circuit which requires no external crystal, into the device. It has been designed to operate efficiently with a USB host controller by using as little as possible of the total USB bandwidth available.
Asynchronous Bit Bang Mode.
Synchronous Bit Bang Mode.
High Output Drive Option.
Programmable FIFO RX Buffer Timeout.
Powered from USB bus or external power supply
USBPWRJMP: jumper for selecting USB or external power supply source, short it for USB and open it for external
VCC, GND pin headers:
When USBPWRJMP is opened, the board should be powered from external supply, use them for power input
When USBPWRJMP is shorted, the board is powered from USB bus, use them for power output
Voltage level is configurable via on-board jumper, VCC or 3.3V
