Features

Fast access times: 9.5/10/12 ns Single or +3.3V-5% power supply Synchronous burst function Individual Byte Write control and Global Write

The is a high-speed, low-power SRAM containing 4,194,304 bits of bit synchronous memory, organized as 131,072 words by 32 bits. The A63L73321 combines advanced synchronous peripheral circuitry, 2-bit burst control, input registers, output buffer and X 32 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 A16), all data inputs - I/O32), active LOW chip enable ( CE two additional chip enables (CE2, CE2 burst control inputs ( ADSC , ADSP , ADV byte write enables ( BWE 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 A63L73321 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/O8, BW2 controls I/O16, BW3 controls - I/O24, and BW4 controls - I/O32, all on the condition that BWE is LOW. GW LOW causes all bytes to be written.
