Infineon Technologies CY7C1470BV33-200AXI

Overview

CY7C1470BV33 from Cypress Semiconductor is a 72-Mbit (2M × 36) synchronous pipelined SRAM with NoBL™ architecture, designed for high-throughput memory subsystems in networking and telecom line cards. It operates at 200 MHz with zero wait states, supports 3.3 V core supply and 3.3 V/2.5 V I/O, and delivers 3.0 ns clock-to-output time. Its fully registered inputs/outputs enable true back-to-back read/write operations in burst or single-access modes.

For engineers reviewing the CY7C1470BV33 datasheet, CY7C1470BV33 pinout, CY7C1470BV33 application, or CY7C1470BV33 equivalent, key selection criteria include its 100-pin TQFP package, byte-write capability across four 9-bit data groups (DQa–DQd + DQPa–DQPd), synchronous self-timed write control, and JTAG boundary-scan compliance for system-level testability.

Technical Context

The CY7C1470BV33 implements a No Bus Latency™ architecture with fully synchronous, rising-edge-triggered registers on all address, control, and data paths. Its internal burst logic supports linear or interleaved addressing, and the ADV/LD pin controls either counter advancement or new address loading - critical for sequential packet buffering.

Three chip enables (CE1 low, CE2 high, CE3 low) provide hierarchical bank selection, while OE remains asynchronous to tri-state outputs during write cycles and deselected states. The CEN pin suspends clock recognition without deselecting the device, enabling precise cycle extension for timing-critical bus arbitration.

FAQ

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

The ADV/LD pin controls the internal address counter behavior: when HIGH (with CEN active), it advances the burst counter for sequential accesses; when LOW, it loads a new address from A0–A17. This dual-mode operation enables both burst streaming and random-access flexibility within a single memory interface, eliminating the need for external address generation logic in packet buffer applications.

Does CY7C1470BV33 support 2.5 V I/O signaling?

Yes - the VDDQ supply accepts 2.5 V ±0.2 V, allowing direct interfacing with 2.5 V logic families such as SSTL-2 without level shifters. The device maintains full 200 MHz operation and timing specifications under 2.5 V I/O conditions, as verified in the AC switching characteristics table of the official datasheet (Document 001-15031 Rev. *O).

How does the ZZ Sleep Mode reduce power consumption?

When the ZZ pin is driven LOW, the CY7C1470BV33 enters a low-power retention state drawing ≤120 mA standby current while preserving all stored data. Unlike standard standby, ZZ mode disables internal clocks and output drivers more aggressively - critical for power-gated subsystems in carrier-grade equipment where thermal envelope and energy efficiency are tightly constrained.

Is CY7C1470BV33 pin-compatible with ZBT SRAMs?

Yes - the CY7C1470BV33 is explicitly designed as pin-compatible and functionally equivalent to ZBT™ SRAMs, including identical pin assignments for address, data, control, and power terminals. This allows drop-in replacement in existing ZBT-based designs while delivering improved performance via NoBL™ architecture and enhanced features like JTAG and ZZ sleep mode.
