Functional Description
[1]
The CY7C1480V25/CY7C1482V25/CY7C1486V25 SRAM
integrates 2M x 36/4M x 18/1M × 72 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
), 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 rising edge of
clock when either Address Strobe Processor (ADSP) or
Address Strobe Controller (ADSC) is 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 7
and
“Truth
Table” on page 10
for further details). Write cycles can be one
to two or four bytes wide, as controlled by the byte write control
inputs. When it is active LOW, GW causes all bytes to be
written.
The CY7C1480V25/CY7C1482V25/CY7C1486V25 operates
from a +2.5V core power supply while all outputs may operate
with either a +2.5 or +1.8V supply. All inputs and outputs are
JEDEC-standard JESD8-5-compatible.
