Input Ports

This table lists the input ports for the Altera ASMI Parallel IP core.

Table 2: Input Ports

Port Condition Size Descriptions

addr[] Required 24 or

32 bit

Contains the value of the EPCS/EPCQ/EPCQ-L memory

address to be read from, written to, and erased from.

For EPCQ256/EPCQ-L256 or larger devices, the width of

the addr[] is 32 bit.

asmi_dataout[] Optional 1 bit Input port to feed data from EPCS/EPCQ/EPCQ-L device if

select the Disable dedicated Active Serial interface option.

If you are using Arria

V, Cyclone

V, Stratix

V, or Arria

10 devices, then the bit size is 4 bit.

bulk_erase Optional 1 bit Active-high port that executes the bulk erase operation. If

asserted, the IP core performs a full-erase operation that sets

all memory bits of the EPCS/EPCQ/EPCQ-L256 device to

‘1’, which includes the general purpose memory of the

EPCS/EPCQ/EPCQ-L device.

clkin Required 1 bit Input clock port for the ASMI block. In general, the clkin

signal must toggle at the appropriate frequency range at all

times. The IP core uses the signal to feed the EPCS/EPCQ/

EPCQ-L device and to perform internal processing.

datain[] Optional 8 bit Parallel input data of 1-byte length for write and sector

protect operations.

en4b_addr Required 1 bit When you select EPCQ256/EPCQ-L256 or larger devices as

your configuration device, address width will change from

0..23 to 0..31. EPCQ256 supports Dual and Quad data

width.

If you select EPCQ256/EPCQ-L256 or larger devices as your

configuration device, this port is required.
