Infineon Technologies CY7C1472V33-200AXC

Overview

CY7C1472V33 from Infineon Technologies (formerly Cypress) is a 72-Mbit synchronous pipelined SRAM with NoBL™ architecture, configured as 2M × 36 or 4M × 18, operating at 200 MHz with zero wait states, 3.0 ns clock-to-output delay, and single 3.3 V core supply - used in high-throughput network packet buffering and FPGA co-processor data staging.

For engineers reviewing the CY7C1472V33 datasheet, CY7C1472V33 pinout, CY7C1472V33 application, or CY7C1472V33 equivalent, key selection criteria include burst mode support (linear/interleaved), byte write capability (BWa–BWb), synchronous self-timed writes, JTAG boundary scan compliance, and TQFP-100 package compatibility with ZBT pinouts.

Technical Context

This SRAM implements fully registered pipelined operation: all address, control, and data signals are synchronized to the rising edge of CLK; output registers ensure deterministic timing, eliminating asynchronous OE dependency. The NoBL™ logic enables true back-to-back read/write cycles without bus latency.

It supports three chip enables (CE1/CE2/CE3) for bank selection, burst addressing via ADV/LD, and dual I/O voltage support (3.3 V core / 2.5 V or 3.3 V I/O). Sleep mode is controlled by the ZZ pin (Pin 64), which must be externally grounded per errata.

FAQ

What is the required connection for the ZZ pin on CY7C1472V33?

The ZZ pin (Pin 64) must be externally connected to ground to enable proper deep sleep mode operation, as documented in the errata on page 35 of Rev. *Y datasheet. Leaving ZZ floating or pulling high disables sleep functionality and may cause excessive standby current.

Does CY7C1472V33 support 2.5 V I/O while operating on 3.3 V core?

Yes - the device features separate VDDQ (I/O) and VDD (core) supplies. VDDQ can be set to 2.5 V ±0.2 V while VDD remains at 3.3 V ±0.3 V, enabling direct interface to 2.5 V FPGAs or ASICs without level shifters.

How does burst addressing work with ADV/LD and MODE pins?

When ADV/LD is asserted, the internal burst counter increments on each CLK rising edge. MODE pin selects linear (MODE = low) or interleaved (MODE = high) address sequencing - matching Intel or Motorola bus protocols respectively - with no external address generation logic required.

Is CY7C1472V33 pin-compatible with standard ZBT SRAMs?

Yes - it is explicitly designed as pin-compatible and functionally equivalent to ZBT devices (e.g., IDT72V2115), sharing identical TQFP-100 footprint, signal naming, and timing behavior, allowing drop-in replacement in existing ZBT-based designs.
