Features

Functional Description

■ Pin-compatible and functionally equivalent to Zero Bus

Turnaround (ZBT™)

The CY7C1460KV33/CY7C1460KVE33/CY7C1462KVE33 are

3.3 V, 1M × 36, and 2M × 18 synchronous pipelined burst SRAMs

with No Bus Latency™ (NoBL™) logic, respectively. They are

designed to support unlimited true back-to-back read/write

■ Supports 250-MHz bus operations with zero wait states

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

operations

with

states.

The

■ Internally self-timed output buffer control to eliminate the need

to use asynchronous OE

CY7C1460KV33/CY7C1460KVE33/CY7C1462KVE33 devices

are equipped with the advanced (NoBL) logic required to enable

consecutive read/write operations with data being transferred on

every clock cycle.

■ Fully-registered (inputs and outputs) for pipelined operation

■ Byte write capability

This feature dramatically improves the throughput of data in

systems that require frequent write and read transitions. The

CY7C1460KV33/CY7C1460KVE33/CY7C1462KVE33 devices

are pin-compatible and functionally equivalent to ZBT devices.

■ 3.3-V power supply

■ 3.3-V/2.5-V I/O power supply

■ Fast clock-to-output time

❐ 2.5 ns (for 250-MHz device)

All synchronous inputs pass through input registers controlled by

the rising edge of the clock. All data outputs pass through output

registers controlled by the rising edge of the clock. The clock

input is qualified by the clock enable (CEN) signal, which when

deasserted suspends operation and extends the previous clock

cycle.

■ Clock enable (CEN) pin to suspend operation

■ Synchronous self-timed writes

■ CY7C1460KV33,

CY7C1460KVE33,

CY7C1462KVE33

available in JEDEC-standard Pb-free 100-pin TQFP, Pb-free

and non Pb-free 165-ball FBGA packages

Write operations are controlled by the byte write selects

(BW_a–BW_d

for

CY7C1460KV33/CY7C1460KVE33

and

■ IEEE 1149.1 JTAG-compatible boundary scan

■ Burst capability—linear or interleaved burst order

■ “ZZ” sleep mode option

BW_a–BW_bfor CY7C1462KVE33) and a write enable (WE) input.

All writes are conducted with on-chip synchronous self-timed

write circuitry.

Three synchronous chip enables (CE₁, CE₂, and CE₃) and an

asynchronous output enable (OE) enable easy bank selection

and output tristate control. To avoid bus contention, the output

drivers are synchronously tristated during the data portion of a

write sequence.

■ On-chip Error Correction Code (ECC) to reduce Soft Error Rate
