Infineon Technologies CY7C1470BV25-167AXC

Overview

CY7C1470BV25-167AXC 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 ASIC/FPGA interfaces. It operates at 167 MHz with 3.4 ns maximum access time, supports zero-wait-state burst reads/writes, and uses single 2.5 V core and I/O supply. Its 100-pin TQFP package enables dense board layout in packet buffer and cache applications.

For engineers reviewing the CY7C1470BV25-167AXC datasheet, CY7C1470BV25-167AXC pinout, CY7C1470BV25-167AXC application, or CY7C1470BV25-167AXC equivalent, key selection criteria include guaranteed 167 MHz bus timing, byte-write select control (BWa–BWd), synchronous self-timed write capability, and JTAG boundary-scan compliance for system-level testability.

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. Internal burst logic supports linear or interleaved addressing via MODE pin configuration.

It features synchronous self-timed writes with on-chip write timing control, eliminating external write pulse generation. Output drivers are synchronously tri-stated during write data cycles to prevent bus contention, and OE remains masked during those phases regardless of its state.

FAQ

What is the function of the MODE pin on CY7C1470BV25-167AXC?

The MODE pin selects burst address order: pulled HIGH for interleaved burst (default when floating), pulled LOW for linear burst. It must remain static during operation and is sampled only at power-up or reset. This configuration directly determines how consecutive burst accesses increment the internal address counter, matching specific ASIC or FPGA memory controller expectations.

Does CY7C1470BV25-167AXC support asynchronous output enable?

Yes - OE is an asynchronous input that controls I/O direction, but its effect is masked during the data portion of write cycles, first clock after deselection, and while the device is deselected. This ensures outputs never drive during write data capture, preventing bus contention without requiring precise OE timing coordination.

How does the CEN pin affect power consumption and timing?

CEN is a synchronous clock gate: when deasserted HIGH, it extends the previous clock cycle without deselecting the device, reducing dynamic switching current. Unlike full chip disable, CEN retains internal state, enabling fast resumption of operation - ideal for burst gap management in streaming applications.

Can CY7C1470BV25-167AXC be used in place of ZBT™ SRAMs?

Yes - it is pin-compatible and functionally equivalent to ZBT™ devices per Cypress documentation, supporting identical control protocols, timing models, and burst behaviors. Migration requires no PCB change and preserves existing FPGA/ASIC interface logic, while offering improved power efficiency via 2.5 V operation.
