Cypress Semiconductor Corp CY7C1354C-200AXCT

Overview

CY7C1354C-200AXCT from Cypress Semiconductor is a 9-Mbit (256K × 36) synchronous pipelined SRAM with NoBL™ architecture, designed for high-throughput memory subsystems in network switches and packet buffers. It operates at 200 MHz with zero wait states, supports 3.3 V core supply and 2.5/3.3 V I/O, and delivers 3.2 ns clock-to-output timing.

For engineers reviewing the CY7C1354C-200AXCT datasheet, CY7C1354C-200AXCT pinout, CY7C1354C-200AXCT application, or CY7C1354C-200AXCT equivalent, key selection criteria include burst order configuration (linear/interleaved), byte-write select granularity (BWa–BWd), synchronous self-timed write control, and compatibility with ZBT-style bus protocols in back-to-back read/write systems.

Technical Context

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

It features four independent byte-write enables (BWa–BWd), synchronous self-timed writes, clock enable (CEN) for cycle extension, and IEEE 1149.1 JTAG boundary scan. Burst mode is selectable via MODE pin (linear or interleaved), and output drivers are synchronously tristated during write data phases to prevent bus contention.

FAQ

What is the function of the MODE pin on CY7C1354C-200AXCT?

The MODE pin is a static strap input that configures burst address sequencing: tied HIGH for interleaved burst order (e.g., 0, 2, 4, 6…), pulled LOW for linear burst order (e.g., 0, 1, 2, 3…). It must be set before initialization and remains latched during operation; no reconfiguration is possible mid-operation.

Can CY7C1354C-200AXCT operate with 2.5 V I/O while using 3.3 V core supply?

Yes. The device supports independent VDD (3.3 V ±0.3 V) and VDDQ (2.5 V ±0.2 V or 3.3 V ±0.3 V) supplies. This allows direct interface with 2.5 V FPGA I/O banks while maintaining full 200 MHz performance and 3.2 ns access timing - verified in Cypress AC switching characteristics tables.

How does the ZZ (sleep) mode reduce power consumption?

Asserting ZZ asynchronously places the device into deep sleep, cutting CMOS standby current to ≤40 mA (typical) while retaining memory contents. Unlike CEN-based clock gating, ZZ disables internal clocks and bias circuits - resulting in ~60% lower quiescent power versus active standby, with wake-up latency under 100 ns.

Is CY7C1354C-200AXCT pin-compatible with ZBT SRAMs?

Yes - it is explicitly designed as pin-compatible and functionally equivalent to industry-standard ZBT SRAMs (e.g., IDT ZBT series). Signal mapping, timing conventions, and burst protocol behavior match ZBT specifications, enabling drop-in replacement in existing ZBT-based designs without layout or firmware changes.
