Functional Description
The CY7C1360C/CY7C1362C 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 (CE
Enables (CE
and ADV), Write Enables (BW
(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 cause s all bytes to be written.
The CY7C1360C/CY7C1362C operates from a +3.3V core
power supply while all outputs may operate with either a +2.5
or +3.3V supply. All inputs and outputs are JEDEC-standard
JESD8-5-compatible.
