Infineon Technologies CY7C1470BV25-250AXC

Overview

CY7C1470BV25-250AXC from Cypress Semiconductor is a 72-Mbit (2M × 36) synchronous pipelined SRAM with NoBL™ architecture, designed for high-throughput memory subsystems in networking and telecom line cards. It operates at 250 MHz with zero wait states, delivers 3.0 ns clock-to-output delay, supports byte-write via four BW inputs, and uses single 2.5 V core and I/O supplies.

For engineers reviewing the CY7C1470BV25-250AXC datasheet, CY7C1470BV25-250AXC pinout, CY7C1470BV25-250AXC application, or CY7C1470BV25-250AXC equivalent, key selection criteria include burst mode configuration (linear/interleaved), synchronous self-timed write timing, JTAG boundary-scan support, and TQFP/FBGA package compatibility for PCB layout and thermal management.

Technical Context

This SRAM implements fully registered pipelined operation: all address, control, and data signals are latched on the rising edge of CLK, with CEN qualifying clock recognition and ADV/LD controlling burst counter advance or new address load. Internal self-timed output buffer control eliminates asynchronous OE dependency for read timing.

The device supports both linear and interleaved burst orders via the MODE strap pin, provides IEEE 1149.1 JTAG boundary scan for board-level test, and enables depth expansion using three synchronous chip enables (CE1–CE3) plus asynchronous OE for output tri-state control during writes.

Key Specifications

FAQ

What is the function of the MODE pin on CY7C1470BV25-250AXC?

The MODE pin is a static strap input that selects burst address order: pulled HIGH for interleaved burst (default when floating), LOW for linear burst. It must remain stable during operation and is sampled at power-up or reset. This setting directly affects how the internal address counter increments during burst reads/writes, aligning with host processor burst protocols.

Does CY7C1470BV25-250AXC support true dual-port operation?

No. CY7C1470BV25-250AXC is a single-port synchronous SRAM with pipelined read/write capability. While it supports back-to-back accesses without wait states, it lacks independent read and write ports. True dual-port functionality requires separate address/data buses and arbitration logic not present in this device.

How does the ZZ (Sleep) mode reduce power consumption?

Asserting ZZ LOW places the device in deep sleep mode, reducing CMOS standby current to ≤120 mA while retaining memory contents. Unlike standard standby, ZZ disables internal clocks and non-essential circuitry without requiring reinitialization upon wake. It is compatible with all burst modes and retains address counter state.

Can CY7C1470BV25-250AXC be used with a 3.3 V interface?

No. CY7C1470BV25-250AXC requires strict 2.5 V ±0.2 V for both VDD (core) and VDDQ (I/O). Driving inputs above 2.7 V violates absolute maximum ratings and may cause latch-up or permanent damage. Level-shifting is mandatory for interfacing with 3.3 V systems.
