PRELIMINARY

72-Mbit (2M x 36/4M x 18/1M x 72) Pipelined

Sync SRAM

Features

Functional Description^[1]

• Supports bus operation up to 250 MHz

• Available speed grades are 250, 200,167 MHz

• Registered inputs and outputs for pipelined operation

• 3.3V core power supply

The CY7C1480V33/CY7C1482V33/CY7C1486V33 SRAM

integrates 2,097,152 x 36/4,194,304 x 18,1,048,576 × 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 (CE₁), depth-expansion Chip Enables (CE₂and

CE₃), 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.

• 2.5V / 3.3V I/O operation

• Fast clock-to-output times

— 3.0 ns (for 250-MHz device)

— 3.0 ns (for 200-MHz device)

— 3.4 ns (for 167-MHz device)

• Provide high-performance 3-1-1-1 access rate

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).

• User-selectable burst counter supporting Intel^®

Pentium^®interleaved or linear burst sequences

• Separate processor and controller address strobes

• Synchronous self-timed writes

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 two or four bytes wide as

controlled by the byte write control inputs. GW when active

• Asynchronous output enable

• Single Cycle Chip Deselect

• CY7C1480V33 and CY7C1482V33 offered in

JEDEC-standardlead-free100-pinTQFP, 165-BallfBGA

packages. CY7C1486V33 available in 209-Ball BGA

packages

causes all bytes to be written.

LOW

The CY7C1480V33/CY7C1482V33/CY7C1486V33 operates

from a +3.3V core power supply while all outputs may operate

with either a +2.5 or +3.3V supply. All inputs and outputs are

JEDEC-standard JESD8-5-compatible.

• IEEE 1149.1 JTAG-Compatible Boundary Scan

• “ZZ” Sleep Mode Option
