Infineon Technologies CY7C1470BV33-250BZXC

Overview

CY7C1470BV33-250BZXC from Cypress Semiconductor is a 72-Mbit (2M × 36) pipelined synchronous SRAM with NoBL™ architecture, designed for high-throughput memory buffering in network packet processors and telecom line cards. It operates at 250 MHz with zero wait states, delivers 3.0 ns clock-to-output time, supports byte-write control via four BW pins (BWa–BWd), and uses a single 3.3 V core supply with 3.3 V/2.5 V I/O compatibility.

For engineers reviewing the CY7C1470BV33-250BZXC datasheet, CY7C1470BV33-250BZXC pinout, CY7C1470BV33-250BZXC application, or CY7C1470BV33-250BZXC equivalent, key selection criteria include burst read/write timing integrity, synchronous self-timed write latency, JEDEC-compliant 100-pin TQFP packaging, and IEEE 1149.1 JTAG boundary-scan support for system-level testability.

Technical Context

The device implements fully registered synchronous interfaces: all address, control, and data inputs pass through input registers on the rising CLK edge; all outputs are latched by output registers synchronized to the same edge. Its NoBL™ logic eliminates bus latency by enabling true back-to-back read/write operations without wait states.

Internal self-timed output buffer control removes dependency on asynchronous OE for tri-state management, while synchronous CEN suspends clock recognition without deselecting the device. Burst capability supports both linear and interleaved orders, and ZZ Sleep Mode reduces standby current to 120 mA.

FAQ

What is the function of the ADV/LD pin in CY7C1470BV33-250BZXC?

The ADV/LD pin controls the internal burst address counter: when HIGH and CEN is active, it advances the counter for sequential burst access; when LOW, it loads a new starting address from A0–A17. This dual-mode operation enables both continuous streaming and random-access initiation without external address generation logic.

Does CY7C1470BV33-250BZXC support 2.5 V I/O signaling?

Yes - the device features separate VDDQ pins supporting 2.5 V or 3.3 V I/O voltage, allowing direct interfacing with 2.5 V FPGA I/O banks or ASIC cores while maintaining 3.3 V core operation. VDDQ must be externally decoupled and set before VDD during power-up sequencing.

How does the ZZ Sleep Mode affect data retention?

In ZZ Sleep Mode (pin driven LOW), the device enters a low-power state with 120 mA standby current while retaining all stored data. Internal refresh circuitry remains active, and data integrity is guaranteed across the full industrial temperature range (–40°C to +85°C) without external intervention.

Can CY7C1470BV33-250BZXC be used as a drop-in replacement for ZBT™ SRAMs?

Yes - it is pin-compatible and functionally equivalent to ZBT™ devices such as the IDT72T36120, supporting identical control protocols, burst orders, and timing models. No PCB redesign or firmware changes are required when migrating to leverage its improved 250 MHz performance and NoBL™ latency benefits.
