72-Mbit (2 M × 36/4 M × 18)

Pipelined Sync SRAM

72-Mbit (2

M × 36/4 M × 18) Pipelined Sync SRAM

Features

Functional Description

■ Supports bus operation up to 250 MHz

■ Available speed grades are 250, 200, and 167 MHz

■ Registered inputs and outputs for pipelined operation

■ 3.3 V core power supply

The CY7C1480BV33 and CY7C1482BV33 SRAM integrates

2 M × 36/4 M × 18 SRAM cells with advanced synchronous

peripheral circuitry and a 2-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.

■ 2.5 V/3.3 V I/O operation

■ Fast clock-to-output times

❐ 3.0 ns (for 250 MHz device)

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

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 may 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 sections Pin Definitions on page 6 and Truth

Table on page 9 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.

■ Asynchronous output enable

■ Single cycle chip deselect

■ CY7C1480BV33 available in JEDEC-standard Pb-free 100-pin

thin quad flat pack (TQFP), Pb-free and non Pb-free 165-ball

fine-pitch ball grid array (FBGA) package. CY7C1482BV33

available in non Pb-free 165-ball fine-pitch ball grid array

(FBGA) package

The CY7C1480BV33 and CY7C1482BV33 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.

For

best

practices

■ IEEE 1149.1 JTAG-compatible boundary scan

■ “ZZ” sleep mode option

recommendations, refer to the Cypress application note AN1064

“SRAM System Guidelines”.
