CY7C1356A-166AC

Memory IC Overview

The CY7C1356A-166AC is a 9-Mbit (512K x 18) pipelined synchronous SRAM featuring NoBL architecture. It operates at clock frequencies up to 166 MHz with a maximum access time of 3.6 ns. The device utilizes a single 3.3V power supply and supports separate 3.3V or 2.5V I/O supplies. It includes registered address, data, and control inputs triggered by the positive clock edge, along with an internal 2-bit burst counter for four-word interleaved or linear sequences.

Memory IC Feature Summary

• Eliminates dead cycles between read and write transitions via Zero Bus Latency architecture
• Integrates registered synchronous inputs for fully pipelined operation
• Supports individual byte write control for targeted data updates
• Includes JTAG boundary scan capabilities for test access

Memory IC Applications

• High-performance networking equipment requiring low latency
• Telecommunications systems utilizing synchronous data processing
• Industrial automation controllers needing fast memory access

Memory IC Procurement Notes

Verify the specific speed grade suffix matches the required 166 MHz performance level. Confirm that the package type aligns with the target PCB footprint, as this component family offers both TQFP and BGA options. Ensure voltage requirements for VCC and VCCQ are compatible with the system design before ordering.

Memory IC Selection Notes

Select this model when zero bus latency is critical for system throughput. Choose based on the required data width; this specific part provides an 18-bit interface. Consider the available package styles if board space is constrained, noting that BGA versions offer lower profiles compared to standard TQFP packages.

Memory IC Part Context

This component belongs to the Cypress NoBL SRAM family, designed to optimize bus utilization in synchronous applications. It shares architectural similarities with the CY7C1354A but differs in density and data width. The series is characterized by its ability to pipeline address and control signals to maintain high-speed data transfer rates without wait states.
