Functional Description[1]

The CY7C1440AV33/CY7C1442AV33/CY7C1446AV33 SRAM integrates 1 M x 36/2 M x 18 and 512 K x 72 SRAM cells with advanced synchronous peripheral circuitry and a two-bit counter for internal burst operation. All synchronous inputs are gated by registers controlled by a positive-edge-triggered clock input CLK . The synchronous inputs include all addresses, all data inputs, address-pipelining chip enable CE1 , depth-expansion chip enables CE2 and CE3 , burst control inputs ADSC, ADSP, and ADV , write enables BWX and BWE , and global write GW . Asynchronous inputs include the output enable OE and the ZZ pin.

Addresses and chip enables are registered at rising edge of clock when either address strobe processor ADSP or address strobe controller ADSC are active. Subsequent burst addresses can be internally generated as controlled by the advance pin ADV .

Address, data inputs, and write controls are registered on-chip to initiate a self-timed write cycle.This part supports byte write operations see pin descriptions and truth table for further details . Write cycles can be one to two or four bytes wide as controlled by the byte write control inputs. GW when active LOW causes all bytes to be written.

CY7C1440AV33/CY7C1442AV33/CY7C1446AV33
operates from a V core power supply while all outputs may
operate with either a or V supply. All inputs and outputs
are JEDEC-standard JESD8-5-compatible.
