Functional Description
[1]
The CY7C1366B/CY7C1367B SRAM integrates 262,144 x 36 and 524,288 x 18 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 ( Enables (CE and
ADV
(
). Asynchronous inputs include the Output Enable (OE)
GW
and the ZZ pin.

Addresses and chip enables are registered at rising edge of clock when either Address Strobe Processor ( Address Strobe Controller (

) or
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 four bytes wide as controlled by the byte write control inputs. GW causes all bytes to be written.
This device incorporates an
active
LOW
additional pipelined enable register which delays turning off the output buffers an additional cycle when a deselect is executed.This feature allows depth expansion without penal­izing system performance.
The CY7C1366B/CY7C1367B operates from a +3.3V core power supply while all outputs operate with a +3.3V or a +2.5V supply. All inputs and outputs are JEDEC-standard JESD8-5-compatible.

ZZ “sleep” Input, active HIGH. When asserted HIGH
places the device in a non-time-critical “sleep” condition with data integrity preserved. For normal operation, this pin has to be LOW or left floating. ZZ pin has an internal pull-down.
Bidirectional Data I/O lines. As inputs, they feed into an on-chip data register that is triggered by the rising edge of CLK. As outputs, they deliver the data contained in the memory location specified by the addresses presented during the previous cycle. The direction of the pins is controlled by OE When OE When HIGH, DQs and DQP condition.
