Functional Description
The CY7C1360C/CY7C1362C SRAM integrates 256 K × 36 and
512 K × 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
1
), depth-expansion chip enables (CE
2
and
CE
3[1]
), burst control inputs (ADSC, ADSP, and ADV), write
enables (BW
X
, and BWE), and global write (GW). Asynchronous
inputs include the output enable (OE) and the ZZ pin.
Addresses and chip enables are registered at the 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 Definitions on page 8
and
Truth Table on
page 11
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.
The CY7C1360C/CY7C1362C operate from a +3.3 V core power
supply while all outputs may operate with either a +2.5 or +3.3 V
supply. All inputs and outputs are JEDEC-standard
JESD8-5-compatible.
