Description

A0, A1, A

Input-

Address Inputs used to select one of the address locations. Sampled at the rising edge

Synchronous

of the CLK if ADSP or ADSC is active LOW, and CE1, CE2, and CE3[2]are sampled active.

A1: A0 are fed to the two-bit counter.

A,

B,

Input-

BW

BW

Byte Write Select Inputs, active LOW. Qualified with

to conduct byte writes to the

BWE

BWC, BWD,

Synchronous

SRAM. Sampled on the rising edge of CLK.

BWE, BWF,

BWG, BWH

Input-

Global Write Enable Input, active LOW. When asserted LOW on the rising edge of CLK,

GW

Synchronous

a global write is conducted (ALL bytes are written, regardless of the values on BWX and

BWE).

Input-

Byte Write Enable Input, active LOW. Sampled on the rising edge of CLK. This signal

BWE

Synchronous

must be asserted LOW to conduct a byte write.

CLK

Input-

Clock Input. Used to capture all synchronous inputs to the device. Also used to increment

Clock

the burst counter when ADV is asserted LOW, during a burst operation.

1

Input-

Chip Enable 1 Input, active LOW. Sampled on the rising edge of CLK. Used in conjunction

CE

Synchronous

with CE2 and CE3 to select/deselect the device. ADSP is ignored if CE1 is HIGH. CE1 is

sampled only when a new external address is loaded.
