Functional Description
The CY7C1339G SRAM integrates 128K × 32 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 (BW[A:D], 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 Pin Descriptions and Truth Table for further
details). Write cycles can be one to four bytes wide as controlled
by the byte write control inputs. GW when active LOW causes all
bytes to be written.
The CY7C1339G operates 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.

I/O- Bidirectional data I/O lines. As inputs, they feed into an on-chip data register that is triggered by the
synchronous rising edge of CLK. As outputs, they deliver the data contained in the memory location specified by the
addresses presented during the previous clock rise of the read cycle. The direction of the pins is
controlled by OE. When OE is asserted LOW, the pins behave as outputs. When HIGH, DQs are placed
in a tri-state condition.
Power supply Power supply inputs to the core of the device.
Ground Ground for the core of the device.
I/O power Power supply for the I/O circuitry.

I/O ground Ground for the I/O circuitry.
Input-
static
Selects burst order. When tied to GND selects linear burst sequence. When tied to VDD or left floating
selects interleaved burst sequence. This is a strap pin and should remain static during device operation.
Mode pin has an internal pull-up.
No Connects. Not internally connected to the die. NC/9M, NC/18M, NC/72M, NC/144M, NC/288M,
NC/576M and NC/1G are address expansion pins are not internally connected to the die.
