Functional Description
The CY7C1380D/CY7C1380F/CY7C1382D SRAM integrates
524,288 × 36 and 1,048,576 × 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 (CE1), depth-expansion
chip enables (CE2 and CE3), burst control inputs (ADSC, ADSP,
and ADV), write enables (BWX, 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 address strobe processor (ADSP) or address strobe
controller (ADSC) are active. Subsequent burst addresses can
be internally generated as they are 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 6 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. GW
when active LOW causes all bytes to be written.
The CY7C1380D/CY7C1380F/CY7C1382D operates from a
+3.3 V core power supply while all outputs operate with a +2.5
or +3.3 V power supply. All inputs and outputs are
JEDEC-standard and JESD8-5-compatible.
