I/O Banks
Programmable Input/Output (PIO) blocks surround the periphery of the device and connect external components to
the Programmable Logic Blocks (PLBs) and RAM4K blocks via programmable interconnect. Individual PIO pins are
grouped into one of four I/O banks, as shown in
differential I/O and the ability to interface to Mobile DDR memories.

output, or a bidirectional I/O pin with a separate direction control input.
PIO blocks are organized into four separate I/O banks, each with its own voltage supply input, as shown in
The voltage applied to the VCCIO pin on a bank defines the I/O standard used within the bank.

devices, I/O Bank 3, along the left edge of the die, is different than the others and supports specialized I/O standards.
I/O Bank Voltage Supply Inputs Support Different I/O Standards
Because each I/O bank has its own voltage supply, iCE65 components become the ideal bridging device between
different interface standards. For example, the iCE65 device allows a 1.8V-only processor to interface cleanly with a
3.3V bus interface. The iCE65 device replaces external voltage translators.
