Functional Description
The CY7C1364B SRAM integrates 262,144 x 32 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
( CE
Control inputs ( ADSC , ADSP , and ADV ), Write Enables
( BW
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 four bytes wide as
controlled by the Byte Write control inputs. GW when active
LOW causes all bytes to be written.
The CY7C1364B operates from a +3.3V core power supply
while all outputs also operate with a +3.3V supply. All inputs
and outputs are JEDEC-standard JESD8-5-compatible.
