71V3556SA100BGGI8

Overview

The 71V3556SA100BGGI8 is a Synchronous Single Data Rate (SDR) Static Random Access Memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 4 Mbit organized as 128 k x 36 bits. The device supports a maximum clock frequency of 100 MHz with an access time of 5 ns. It operates within a voltage range of 3.135 V to 3.465 V and has a maximum power supply current of 255 mA. The component utilizes a parallel interface and is housed in a 119-pin PBGA package measuring 14x22 mm. It functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed synchronous data transfer via a single data rate interface at up to 100 MHz.
• Provides wide 36-bit data organization suitable for applications requiring large word widths.
• Operates on standard 3.3V I/O levels while maintaining core voltage specifications.

Applications

• High-performance networking equipment requiring fast memory access
• Industrial control systems needing reliable volatile storage
• Telecommunications infrastructure utilizing wide data buses

Procurement Notes

Verify the specific suffix BGGI8 against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as it may vary by production batch or region. Check for End-of-Life notices or Product Change Notifications that might affect long-term availability. Ensure the supplier provides valid traceability documents for the 119-PBGA package.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required. The 100 MHz speed grade offers a balance between performance and power consumption compared to faster variants. The PBGA-119 package is suitable for surface-mount assembly processes. Consider thermal management requirements given the maximum operating current specification during active cycles.

Part Context

This part belongs to the 71V3556SA series of Synchronous ZBT SRAMs from Renesas. The series typically includes variants with different speed grades such as 133 MHz and 166 MHz, and various package options including CABGA and PBGA configurations. The SA designation often indicates specific internal architecture or I/O characteristics within the broader product family.

Replacement Considerations

Official substitutes include other speed grades within the same series, such as the 71V3556SA133BGGI8 or 71V3556SA166BGGI8, provided the system timing allows. Verify pin compatibility and electrical parameters before substitution.
