Cypress Semiconductor Corp CY7C1470BV33-200AXC

Overview

CY7C1470BV33 from Cypress Semiconductor is a 72-Mbit (2M × 36) pipelined synchronous SRAM with NoBL™ architecture, designed for high-throughput memory subsystems in networking and telecom infrastructure. 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 packet buffering and cache applications.

For engineers reviewing the CY7C1470BV33 datasheet, CY7C1470BV33 pinout, CY7C1470BV33 application, or CY7C1470BV33 equivalent, key selection criteria include burst mode support (linear/interleaved), byte write capability via four BW pins, synchronous self-timed writes, JTAG boundary scan compliance, and compatibility with ZBT™-based system designs requiring deterministic latency.

Technical Context

The CY7C1470BV33 implements a synchronous pipelined architecture with on-chip address counters, burst logic, and output register staging-all synchronized to the rising edge of CLK. Its NoBL™ logic eliminates bus latency by enabling consecutive read/write transfers on every clock cycle without interlock delays.

All control signals (CE1, CE2, CE3, WE, ADV/LD, CEN, OE) are sampled synchronously on CLK's rising edge, while OE remains asynchronous for output tri-state control. The device supports linear or interleaved burst orders and includes ZZ Sleep Mode and Stop Clock options for power management in burst-intensive systems.

FAQ

What is the function of the ADV/LD pin in burst operations?

The ADV/LD pin controls the internal address counter behavior: when HIGH and CEN is active, it increments the counter for sequential burst access; when LOW, it loads a new base address from A[17:0]. This enables both continuous streaming and random-start burst modes without external address generation logic, essential for flexible packet header processing.

How does the CY7C1470BV33 handle simultaneous read and write requests?

It does not support true simultaneous read/write on the same port. However, its pipelined architecture allows back-to-back operations-e.g., a write completes on clock N, and a read begins on clock N+1-with no wait states. Internal write data coherency logic ensures reads return updated values after the write cycle finishes, maintaining data integrity in burst pipelines.

Can the CY7C1470BV33 operate with 2.5 V I/O while maintaining 3.3 V core supply?

Yes. VDDQ accepts 2.5 V ± 0.2 V while VDD remains at 3.3 V ± 0.3 V. This dual-voltage I/O capability allows direct interfacing with 2.5 V FPGAs or ASICs without level shifters, reducing signal integrity risk and board space. All AC/DC specifications in the datasheet are validated for this mixed-supply condition.

Is the ZZ pin compatible with standard CMOS logic levels?

Yes. ZZ is a CMOS-compatible input with VIH ≥ 2.0 V and VIL ≤ 0.8 V under 3.3 V supply conditions. When asserted LOW, it places the device in deep sleep mode, reducing ICC to ≤120 mA while retaining memory content and register states. Recovery time from ZZ is 20 ns, enabling rapid reactivation in burst-scheduled systems.
