PRELIMINARY

9-Mbit (256K x 36/512K x 18) Pipelined DCD

Sync SRAM

Features

Functional Description^[1]

• Supports bus operation up to 225 MHz

The CY7C1366C/CY7C1367C SRAM integrates 262,144 x 36

and 524,288 x 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,

• Available speed grades are 225, 200 and 166 MHz

• Registered inputs and outputs for pipelined operation

•Optimal for performance (Double-Cycle deselect)

—Depth expansion without wait state

•3.3V –5% and +10% core power supply (V_DD

• 2.5V / 3.3V I/O operation

— 2.8 ns (for 225-MHz device)

— 3.0 ns (for 200-MHz device)

— 3.5 ns (for 166-MHz device)

Addresses and chip enables are registered at rising edge of

clock when either Address Strobe Processor ( ) or

ADSP

) are active. Subsequent

Address Strobe Controller (

burst addresses can be internally generated as controlled by

the Advance pin ( ).

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

• User-selectable burst counter supporting Intel^

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

packages

• IEEE 1149.1 JTAG-Compatible Boundary Scan

• “ZZ” Sleep Mode Option

The CY7C1366C/CY7C1367C operates from a +3.3V core

power supply while all outputs operate with a +3.3V or a +2.5V

supply. All inputs and outputs are JEDEC-standard

JESD8-5-compatible.
