Infineon Technologies CY7C1470V25-200AXC

Overview

CY7C1470V25-200AXC from Infineon Technologies (formerly Cypress) is a 72-Mbit synchronous pipelined SRAM with NoBL™ architecture, configured as 2M × 36, operating at 200 MHz with zero wait states. It features fully registered I/O, 2.5 V core and I/O supply, 3.0 ns clock-to-output delay, and byte-write capability for high-throughput memory buffering in network packet processors.

For engineers reviewing the CY7C1470V25-200AXC datasheet, CY7C1470V25-200AXC pinout, CY7C1470V25-200AXC application, or CY7C1470V25-200AXC equivalent, key selection criteria include burst mode support (linear/interleaved), synchronous self-timed writes, JTAG boundary scan compliance, and TQFP/FBGA package compatibility for backplane and switch fabric designs.

Technical Context

The device implements a fully synchronous, pipelined read/write interface with all inputs and outputs registered on the rising edge of CLK. Internal NoBL™ logic eliminates bus latency by enabling true back-to-back operations without wait states, sustaining 200 MHz continuous data transfer.

It supports three chip enables (CE1–CE3), clock enable (CEN), asynchronous OE, and four byte write selects (BWa–BWd) for granular 8-bit write control. Sleep mode (ZZ) and stop-clock operation reduce power during idle cycles while maintaining data retention.

FAQ

What is the function of the ZZ pin on CY7C1470V25-200AXC?

The ZZ pin enables deep sleep mode to reduce standby current to ≤120 mA. Per documented errata (Page 36), ZZ must be externally tied to ground for proper operation - leaving it floating or driving it high disables sleep functionality and may cause unpredictable behavior.

Does CY7C1470V25-200AXC support both linear and interleaved burst orders?

Yes - burst order is selected by the MODE pin: logic high configures linear burst, logic low selects interleaved burst. This allows direct compatibility with Intel or Motorola-style processor burst protocols without external address translation logic.

How does the NoBL™ architecture improve system performance compared to standard ZBT SRAMs?

NoBL™ eliminates bus turnaround time by enabling immediate back-to-back reads and writes on every clock cycle. Unlike ZBT devices that require one-cycle gaps between transitions, CY7C1470V25-200AXC sustains full 200 MHz throughput even under mixed read/write workloads typical in packet buffering.

Can CY7C1470V25-200AXC operate with only a 2.5 V supply, or are separate VDD and VDDQ rails required?

Both VDD (core) and VDDQ (I/O) must be supplied at 2.5 V ±0.2 V. Although voltage values match, they are electrically isolated pins per datasheet recommendations to suppress noise coupling between core logic and I/O drivers - using a single shared rail violates recommended layout practice.
