General Description
The A63L73361 is a high-speed SRAM containing 4.5M
bits of bit synchronous memory, organized as 128K
words by 36 bits.
The A63L73361 combines advanced synchronous
peripheral circuitry, 2-bit burst control, input registers,
output buffer and a 128K X 36 SRAM core to provide a
wide range of data RAM applications.
The positive edge triggered single clock input (CLK)
controls all synchronous inputs passing through the
registers. Synchronous inputs include all addresses (A0 -
A17), all data inputs (I/O
1
- I/O
36
), active LOW chip
enable (
CE ), two additional chip enables (CE2, CE2 ),
burst control inputs ( ADSC , ADSP , ADV ), byte write
enables ( BWE , BW1 , BW2 , BW3 , BW4 ) and Global
Write ( GW ). Asynchronous inputs include output enable
( OE ), clock (CLK), BURST mode (MODE) and SLEEP
mode (ZZ).
Burst operations can be initiated with either the address
status processor ( ADSP ) or address status controller
( ADSC ) input pin. Subsequent burst sequence burst
addresses can be internally generated by the A63L73361
and controlled by the burst advance ( ADV ) pin. Write
cycles are internally self-timed and synchronous with the
rising edge of the clock (CLK).
This feature simplifies the write interface. Individual Byte
enables allow individual bytes to be written. BW1 controls
I/O

- I/O

, BW2 controls I/O
10

, BW3 controls

- I/O

, and BW4 controls I/O
28
- I/O
36
, all on the
condition that BWE is LOW. GW LOW causes all bytes
to be written.
