Cypress Semiconductor Corp CY7C1470BV25-200AXI

Overview

CY7C1470BV25-200AXI from Cypress Semiconductor is a 72-Mbit (2M × 36) synchronous pipelined SRAM with NoBL™ architecture, designed for high-throughput memory interfaces in network packet buffers and telecom line cards. It operates at 200 MHz with zero wait states, supports 2.5 V core and I/O supply, delivers 3.0 ns clock-to-output delay, and features fully registered inputs/outputs with byte-write capability.

For engineers reviewing the CY7C1470BV25-200AXI datasheet, CY7C1470BV25-200AXI pinout, CY7C1470BV25-200AXI application, or CY7C1470BV25-200AXI equivalent, key selection criteria include burst order 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

The device implements a fully synchronous, rising-edge-triggered pipeline with three chip enables (CE1 active-low, CE2 active-high, CE3 active-low), Clock Enable (CEN) for cycle extension, and ADV/LD for burst address control. All address, data, and control signals pass through input registers synchronized to CLK.

Output drivers are synchronously tri-stated during write data phases, eliminating bus contention. Internal self-timed write logic removes external write pulse timing constraints, while MODE pin selects linear or interleaved burst order-critical for cache coherency and DMA engine alignment.

FAQ

What is the function of the MODE pin on CY7C1470BV25-200AXI?

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

Does CY7C1470BV25-200AXI support asynchronous output enable (OE)?

Yes, OE is an asynchronous active-low input that controls I/O direction. When asserted LOW, outputs are enabled; when HIGH, outputs enter high-impedance state. However, OE is masked during write data phases, first clock after deselection, and full device deselection-ensuring automatic tri-state behavior without external timing control.

How does the Clock Enable (CEN) pin affect timing behavior?

CEN is a synchronous active-low input that qualifies CLK. When CEN is HIGH, CLK is ignored and all internal states hold; when LOW, CLK is recognized and operations proceed. Unlike chip disable, CEN assertion extends the previous clock cycle without disrupting pipeline state-enabling precise cycle stretching for glueless interface with slower controllers.

Can CY7C1470BV25-200AXI be used in place of ZBT™ SRAMs?

Yes, it is pin-compatible and functionally equivalent to ZBT™ devices, supporting identical control protocols and timing models. However, CY7C1470BV25-200AXI adds NoBL™ advantages: zero-wait-state back-to-back operations, internal self-timed writes, and MODE-configurable burst order-providing measurable throughput gains in burst-intensive applications.
