Infineon Technologies CY7C1470V25-200BZC

Overview

CY7C1470V25-200BZC 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, 3.0 ns clock-to-output delay, and single 2.5 V supply. It enables back-to-back read/write operations in high-throughput networking packet buffers.

For engineers reviewing the CY7C1470V25-200BZC datasheet, CY7C1470V25-200BZC pinout, CY7C1470V25-200BZC application, or CY7C1470V25-200BZC equivalent, key selection criteria include burst mode support (linear/interleaved), byte write capability (BWa–BWd), JTAG boundary scan compliance, and TQFP-100/Pb-free packaging for industrial memory subsystems.

Technical Context

This SRAM implements fully registered synchronous interfaces: all address, control, and data inputs pass through rising-edge-triggered registers, and outputs are edge-aligned via output registers. The NoBL™ logic eliminates bus latency by enabling consecutive read/write cycles without pipeline stalls.

It supports three chip enables (CE1/CE2/CE3), clock enable (CEN) for cycle suspension, synchronous self-timed writes, and dual-bank sleep control via ZZ pin (requires external ground per errata). Burst order is selectable via MODE pin (linear or interleaved).

FAQ

What is the function of the ZZ pin, and how must it be connected?

The ZZ pin enables deep sleep mode to reduce standby current to ≤120 mA. Per documented errata (page 36), ZZ (Pin 64 in TQFP) must be externally connected to ground to ensure reliable entry into sleep mode; leaving it floating or pulling high may cause undefined behavior or failure to enter low-power state.

Does CY7C1470V25-200BZC support both linear and interleaved burst addressing?

Yes - burst order is selected by the MODE pin: logic high configures linear addressing (A0–A19 increment sequentially), logic low selects interleaved (bit-swapped address sequence). This matches legacy ZBT™ devices and modern protocol engine requirements without firmware changes.

How many byte write enable signals does this SRAM provide, and what is their granularity?

It provides four byte write enable inputs (BWa, BWb, BWc, BWd), each controlling a 9-bit segment of the 36-bit data bus. This allows independent write masking of four 9-bit nibbles - essential for updating partial packet headers or metadata without disturbing adjacent payload bytes.

Is JTAG boundary scan supported, and what standard does it comply with?

Yes - it implements IEEE 1149.1 JTAG boundary scan with full TAP controller, instruction register, and boundary scan register. It supports mandatory instructions (SAMPLE/PRELOAD, EXTEST, BYPASS) and optional ones (IDCODE, CLAMP), enabling production test and in-system diagnostics on dense PCBs.
