Cypress Semiconductor Corp CY7C1480V33-200AXC

Overview

CY7C1480V33-200AXC from Cypress Semiconductor is a 72-Mbit pipelined synchronous SRAM configured as 2M × 36, operating at 200 MHz with 3.3 V core supply and 2.5/3.3 V I/O compatibility. It features registered inputs/outputs, synchronous self-timed writes, and user-selectable Intel Pentium®-compatible interleaved or linear burst sequences. Used in high-speed secondary cache subsystems for embedded processors requiring deterministic 3.0 ns clock-to-output timing.

For engineers reviewing the CY7C1480V33-200AXC datasheet, CY7C1480V33-200AXC pinout, CY7C1480V33-200AXC application, or CY7C1480V33-200AXC equivalent, this page delivers verified specifications, JEDEC-compliant TQFP package details, burst control logic behavior, byte-write architecture, and validated alternatives for cache memory design.

Technical Context

This SRAM implements a dual-strobe address capture architecture using ADSP (processor) and ADSC (controller) inputs, with ADV-triggered internal 2-bit wraparound burst counter. All synchronous signals-including address, data, CE1–CE3, BWA–BWD, BWE, GW, and OE-are registered on the rising edge of CLK.

It supports four-byte-wide synchronous writes with per-byte write enable (BWX) and global write override (GW), while maintaining asynchronous OE and ZZ sleep control. Output drivers are registered, delivering guaranteed 3.0 ns tCO at 200 MHz operation with 3.3 V VDD and 2.5 V VDDQ.

FAQ

What is the function of the MODE pin on CY7C1480V33-200AXC?

The MODE pin selects between Intel Pentium®-compatible interleaved burst addressing and linear burst addressing. When MODE is LOW at power-up or reset, the device uses interleaved order (0,2,4,6,… then 1,3,5,7,…); when HIGH, it uses linear order (0,1,2,3,…). This configuration is latched and remains active until next reset or power cycle.

Can CY7C1480V33-200AXC operate with 2.5 V I/O while using 3.3 V core supply?

Yes. The device supports mixed-voltage operation: VDD = 3.3 V powers the core logic and memory array, while VDDQ = 2.5 V supplies the I/O buffers. This allows direct connection to 2.5 V FPGA or ASIC I/O banks without level shifters, provided VSSQ is tied to the same ground as VSS.

How does the ZZ sleep mode affect power consumption and data retention?

When ZZ is driven HIGH, the device enters a low-power sleep state drawing ≤120 mA standby current while preserving all stored data. Core clocks and I/O drivers are gated, but memory cell bias remains active. Data retention is guaranteed over the full industrial temperature range (–40°C to +85°C) with no time limit.

Is the CY7C1480V33-200AXC pin-compatible with CY7C1482BV33-200AXC?

No. Although both share the same FBGA package option, the CY7C1480V33-200AXC (2M × 36) and CY7C1482BV33-200AXC (4M × 18) differ in data bus width, pin assignments for DQ/DQP groups, and internal address mapping. They are not interchangeable without PCB redesign and firmware adaptation.
