Functional Description
The CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
SRAM integrates 512K x 36/1M 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
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) 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
and
for further details). Write cycles can be
one to four bytes wide as controlled by the byte write control
inputs. GW active LOW causes all bytes to be written. This
device incorporates an 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 CY7C1386D/CY7C1387D/CY7C1386F/CY7C1387F
operates from a +3.3V core power supply while all outputs
operate with a +3.3V or +2.5V supply. All inputs and outputs
are JEDEC-standard and JESD8-5-compatible.
