Chip enable: This active HIGH input is used to enable the device.
Output Enable: This active LOW asynchronous input enables the data output drivers.
Address Advance: This active LOW input is used to control the internal burst counter. A
HIGH on this pin generates wait cycle (no address advance).
Address Status Processor: This active LOW input, along with CE# being LOW, causes
a new external address to be registered and a READ cycle is initiated using the new
address.
Address Status Controller: This active LOW input causes device to be de-selected or
selected along with new external address to be registered. A READ or WRITE cycle is
initiated depending upon write control inputs.
Mode: This input selects the burst sequence. A LOW on this pin selects LINEAR
BURST. A NC or HIGH on this pin selects INTERLEAVED BURST.
Snooze: This active HIGH input puts the device in low power consumption standby
mode. For normal operation, this input has to be either LOW or NC (No Connect).
Data Inputs/Outputs: First Byte is DQ1-DQ8. Second Byte is DQ9-DQ16. Third Byte is
DQ17-DQ24. Fourth Byte is DQ25-DQ32. Input data must meet setup and hold times
around the rising edge of CLK.
Parity Inputs/Outputs: DQP1 is parity bit for DQ1-DQ8 and DQP2 is parity bit for DQ9-
DQ16. DQP3 is parity bit for DQ17-DQ24 and DQP4 is parity bit for DQ25-DQ32.
Core power Supply: +3.3V -5% and +10%
Ground: GND.
Output Buffer Supply: +2.5V (from 2.375V to VCC)
Output Buffer Ground: GND
No Connect: These signals are not internally connected.
