RD#
Type
IN
Description
Enables Current FIFO Data Byte on D0..D7 when low. Fetches the next FIFO
Data Byte (if available) from the Receive FIFO Buffer when RD# goes from low
to high.
***
Note 1
Writes the Data Byte on the D0..D7 into the Transmit FIFO Buffer when WR goes
from high to low.
***
Note 1
When high, do not write data into the FIFO. When low, data can be written into
the FIFO by strobing WR high then low.
***
Note 2
When high, do not read data from the FIFO. When low, there is data available in
the FIFO which can be read by strobing RD# low then high again

Type
I/O
Description
EEPROM – Chip Select. For 48MHz operation pull EECS to GND using a 10K
resistor. For 6MHz operation no resistor is required.
***
Note 3
Clock signal to EEPROM. Adding a 10K pull down resistor onto EESK will cause
the FT245BL to use USB Product ID 6005 (hex) instead of 6001 (hex). All of the
other USB device descriptors are unchanged.
***
Note 3
EEPROM – Data I/O Connect directly to Data-In of the EEPROM and to Data-
Out of the EEPROM via a 2.2K resistor. Also pull Data-Out of the EEPROM to
VCC via a 10K resistor for correct operation.
