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, and 167 MHz

• Registered inputs and outputs for pipelined operation

• 3.3V core power supply

The CY7C1480V33/CY7C1482V33/CY7C1486V33 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

(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)

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

• User selectable burst counter supporting Intel^®

Pentium^®interleaved or linear burst sequences

Addresses and chip enables are registered at the rising edge

of the 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).

• Separate processor and controller address strobes

• Synchronous self timed writes

• Asynchronous output enable

• Single cycle chip deselect

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.

GW when active LOW causes all bytes to be written.

• CY7C1480V33, CY7C1482V33 available in

JEDEC-standard Pb-free 100-pin TQFP, Pb-free and

non-Pb-free 165-ball FBGA package. CY7C1486V33

available in Pb-free and non-Pb-free 209-ball FBGA

package

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
