SPI Master Configuration Interface
Power-On Reset (POR)
The Power-on Reset (POR) circuit monitors specific voltage supply inputs and holds the device in reset until all the
relevant supplies exceed the internal voltage thresholds. The SPI_VCC supply also has an additional time-out delay
to allow an attached SPI serial PROM to power up properly.
Nonvolatile Configuration Memory (NVCM) requires that the VPP_2V5 supply be connected, even if the
application does not use the NVCM.
CRESET_B Pin
The
JTAG Interface
Specific command sequences also reset the iCE65 internal logic.
All iCE65 devices, including those with NVCM, can be configured from an external, commodity SPI serial Flash
PROM, as shown in
by the VCC_SPI supply input. Presently, most commercially-available SPI serial Flash PROMs require a 3.3V
supply.
CRESET_B
pin resets the iCE65 internal logic when Low.
