A62S7332E-5

128K X 32 Bit Synchronous High Speed SRAM with Burst Counter and Pipelined Data Output

AMIC Technology 

A63G7332 Series

Notes: 1. X = "Disregard", H = Logic High, L = Logic Low.

2. WRITE = L means:

1) Any BWx ( BW1 , BW2 , BW3 , or BW4 ) and BWE are low or

2) GW is low.

3. All inputs except OE must be synchronized with setup and hold times around the rising edge (L-H) of CLK.

4. For write cycles that follow read cycles, OE must be HIGH before the input data request setup time and held

HIGH throughout the input data hold time.

5. ADSP LOW always initiates an internal Read at the L-H edge of CLK. A Write is performed by setting one or

more byte write enable signals and BWE LOW or GW LOW for the subsequent L-H edge of CLK. Refer to

the Write timing diagram for clarification.
