Infineon Technologies CY7C1472V25-200AXC

Overview

CY7C1472V25-200AXC from Infineon Technologies (formerly Cypress) is a 72-Mbit synchronous pipelined SRAM with NoBL™ architecture, configured as 2M × 36 or 4M × 18 or 1M × 72. It operates at 200 MHz with zero wait states, delivers 3.0 ns clock-to-output time, supports byte write via BWa/BWb pins, and uses single 2.5 V core supply with separate 2.5 V I/O supply (VDDQ). It is deployed in high-throughput network packet buffering and FPGA co-processor memory interfaces.

For engineers reviewing the CY7C1472V25-200AXC datasheet, CY7C1472V25-200AXC pinout, CY7C1472V25-200AXC application, or CY7C1472V25-200AXC equivalent, key selection criteria include burst mode support (linear/interleaved), synchronous self-timed writes, JTAG boundary scan compliance, ZZ sleep mode control, and TQFP-100 package compatibility with legacy ZBT™ designs.

Technical Context

The device implements fully registered pipelined operation: all address, control, and data inputs are latched on the rising edge of CLK; all outputs are driven through output registers synchronized to CLK. Internal self-timed output buffer control eliminates asynchronous OE timing constraints.

It supports three chip enables (CE1, CE2, CE3) for bank selection, burst read/write with ADV/LD and MODE pins, and synchronous write enable (WE) with byte-select granularity (BWa, BWb). The ZZ pin enables low-power sleep mode, and CEN suspends clock domain activity without resetting internal state.

FAQ

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

The ZZ pin enables deep sleep mode, reducing standby current to under 100 µA. Per documented errata (page 36), ZZ (Pin 64) must be externally tied to ground for correct operation - leaving it floating or pulling high causes undefined behavior and potential functional failure. This requirement applies regardless of whether sleep mode is actively used in the design.

How does the NoBL™ architecture improve system throughput compared to standard synchronous SRAMs?

NoBL™ eliminates bus turnaround latency by enabling true back-to-back read/write operations on every clock cycle without wait states. Unlike conventional SRAMs requiring idle cycles between accesses, CY7C1472V25-200AXC sustains 200 MHz continuous data transfer - delivering up to 7.2 GB/s peak bandwidth on its 36-bit bus, critical for packet-forwarding and real-time signal processing pipelines.

Can CY7C1472V25-200AXC operate in 4M × 18 configuration, and what pin changes are required?

Yes - the device supports 4M × 18 mode via MODE pin assertion (MODE = HIGH). In this configuration, the same 36-bit DQa/DQb bus carries two 18-bit words per cycle; address lines A0–A19 are used, and burst length is adjusted accordingly. No physical pin reassignment is needed - only MODE pin voltage and controller burst addressing logic must be configured per datasheet Table 12.

Is JTAG boundary scan supported in all operating modes, including ZZ sleep?

JTAG remains fully operational in all functional states except when ZZ sleep is active - the TAP controller is disabled during ZZ mode to minimize leakage. Boundary scan testing must be performed in active or standby (CEN-deasserted) states. The TCK, TMS, TDI, and TDO pins retain their IEEE 1149.1 functionality and electrical characteristics per AC switching specs in Section 20 of the datasheet.
