Infineon Technologies CY7C1460AV33-167AXC

Overview

CY7C1460AV33 from Cypress Semiconductor is a 3.3V, 1M × 36 pipelined synchronous SRAM with NoBL™ architecture, supporting true back-to-back read/write operations at 167 MHz with zero wait states. It features fully registered inputs/outputs, byte write capability (BWa–BWd), synchronous self-timed writes, and 3.3V/2.5V I/O compatibility. Used in high-throughput packet buffering and network switch fabric control planes.

For engineers reviewing the CY7C1460AV33 datasheet, CY7C1460AV33 pinout, CY7C1460AV33 application, or CY7C1460AV33 equivalent, key selection criteria include burst mode support (linear/interleaved), ZZ sleep mode, JTAG boundary scan compliance, and 100-pin TQFP or 165-ball FBGA package options for board layout and thermal management.

Technical Context

The CY7C1460AV33 implements a pipelined SRAM architecture with No Bus Latency™ logic to eliminate bus turnaround penalties. All address, control, and data signals are synchronized to the rising edge of CLK, and internal address registers (A0–A19) plus burst counter logic enable continuous sequential access without pipeline stalls.

It supports three chip enables (CE1 active-low, CE2 active-high, CE3 active-low) for flexible bank decoding, and uses asynchronous OE with synchronous output tristate control to prevent bus contention during write cycles. The ADV/LD pin controls burst address increment or new address load, while CEN suspends clock recognition without deselecting the device.

FAQ

What is the function of the MODE pin on CY7C1460AV33?

The MODE pin selects burst address sequence behavior: when tied to VDD or left floating, it enables interleaved burst order; when tied to GND, it selects linear burst order. This setting determines how the internal address counter increments during burst reads/writes and must be configured at power-up based on system memory controller requirements.

Can CY7C1460AV33 operate with 2.5V I/O while maintaining 3.3V core voltage?

Yes - VDDQ (I/O supply) accepts 2.5V ±0.2V while VDD (core supply) requires 3.3V ±0.3V. This dual-supply configuration allows direct interfacing with 2.5V FPGAs or ASICs without level shifters, provided VDDQ and VDD sequencing meets tVR/tVF specifications (VDD must stabilize before VDDQ).

How does the ZZ (sleep) mode affect data retention and wake-up time?

In ZZ mode, core power is reduced and outputs are tristated, but SRAM cell data is retained indefinitely as long as VDD remains within specification (≥2.7V). Wake-up latency is one clock cycle after ZZ deassertion; no initialization or refresh is required, enabling rapid resumption of burst operations.

Is the 100-pin TQFP package of CY7C1460AV33 pin-compatible with ZBT SRAMs?

Yes - the CY7C1460AV33 is explicitly designed as pin-compatible and functionally equivalent to industry-standard ZBT SRAMs (e.g., IDT ZBT series), supporting identical footprint, signal mapping, and timing interface, allowing drop-in replacement in existing ZBT-based designs without PCB revision.
