Functional Description
The CY7C1440KV33/CY7C1442KV33/CY7C1440KVE33 SRAM
integrate 1M × 36/2M × 18/1M × 36 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, two or four bytes wide as
controlled by the byte write control inputs. GW when active LOW
causes all bytes to be written.
The CY7C1440KV33/CY7C1442KV33/CY7C1440KVE33
operate from a +3.3 V core power supply while all outputs may
operate with either a +2.5 V or +3.3 V supply. All inputs and
outputs are JEDEC-standard JESD8-5-compatible.
