Infineon Technologies CY7C1470BV33-200BZIT

Overview

CY7C1470BV33-200BZIT from Cypress Semiconductor is a 72-Mbit (2M × 36) synchronous pipelined SRAM with NoBL™ architecture, designed for high-throughput memory buffering in network packet processors 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.

For engineers reviewing the CY7C1470BV33-200BZIT datasheet, CY7C1470BV33-200BZIT pinout, CY7C1470BV33-200BZIT application, or CY7C1470BV33-200BZIT equivalent, this device enables true back-to-back read/write operations without bus latency, supports byte-write control via BWa–BWd, and integrates JTAG boundary scan for production testability.

Technical Context

The CY7C1470BV33-200BZIT implements fully registered synchronous interfaces: all address, control, and data inputs are latched on the rising edge of CLK, and all outputs are driven from output registers synchronized to CLK. Its NoBL™ logic eliminates bus turnaround delay by enabling consecutive read or write cycles with data valid on every clock edge.

It features three synchronous chip enables (CE1 low, CE2 high, CE3 low), asynchronous OE for output tri-state control, and CEN to suspend 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 CY7C1470BV33-200BZIT?

The ADV/LD pin controls the internal burst address counter: when HIGH and CEN is active, it advances the counter for sequential burst accesses; when LOW, it loads a new starting address from A[17:0]. This dual-mode operation enables both continuous streaming and random-access burst initiation without external address generation logic.

Does CY7C1470BV33-200BZIT support 2.5 V I/O operation?

Yes - the device supports 2.5 V I/O voltage on VDDQ pins while maintaining 3.3 V core (VDD) operation. This allows direct interfacing with 2.5 V FPGA I/O banks or ASIC SerDes receivers without level-shifting circuitry, provided VDDQ is externally supplied at 2.5 V ±0.1 V.

How does the ZZ (Sleep) mode affect data retention?

In ZZ mode, the device enters deep sleep with reduced current draw (120 mA typical), but retains full memory content without external refresh. All internal registers and array state remain intact; exit from ZZ mode requires two clock cycles before valid data is available on DQs.

Is CY7C1470BV33-200BZIT pin-compatible with ZBT SRAMs?

Yes - it is pin-compatible and functionally equivalent to ZBT™ SRAMs such as IDT72V2115, sharing identical pinout, timing behavior, and control signal definitions (CE1/CE2/CE3, BWx, ADV/LD). This enables drop-in replacement in existing ZBT-based designs without PCB or firmware changes.
