Memory IC Overview

The 71V3556SA166BQG is a 4.5Mb (128K x 36) synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It operates with a maximum clock frequency of 166 MHz and features a typical access time of 3.5 ns. The device utilizes a parallel interface and requires a supply voltage range of 3.135V to 3.465V. It is housed in a 165-CABGA (13x15) surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

Synchronous Single Data Rate (SDR) architecture for high-speed data transfer
Zero Bus Turnaround (ZBT) technology eliminates dead cycles during bus direction changes
Supports pipelined read operations for improved throughput
Integrated power-on reset and low-power standby modes

Memory IC Applications

High-performance networking equipment
Industrial automation control systems
Telecommunications infrastructure
Embedded storage buffers in computing devices

Memory IC Procurement Notes

Verify the specific suffix 'BQG' against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the family. Confirm availability status, as this component may be discontinued or subject to last-time buy notices. Ensure compliance with RoHS directives and check moisture sensitivity level handling requirements prior to assembly.

Memory IC Selection Notes

Select this component when a 128K x 36 organization is required for wide-data applications. The 166 MHz speed grade suits high-bandwidth interfaces. Compare against the 71V3556S series for standard ZBT performance or the 71V3557 series if lower latency is critical. Ensure the PCB layout supports the 165-CABGA package thermal and mechanical constraints.

Memory IC Part Context

This part belongs to the IDT 71V3556 family of synchronous SRAMs, widely used in embedded systems requiring fast, non-volatile-like access without refresh cycles. The 'SA' suffix typically denotes extended temperature ranges and enhanced reliability features compared to standard commercial grades. The family is designed for applications demanding deterministic timing and high throughput.
