71V124SA10PHGI8

Overview

The Renesas Electronics Corporation 71V124SA10PHGI8 is a 1 Mbit (128K x 8) asynchronous static random-access memory (SRAM) integrated circuit. It operates with a single 3.3V power supply, supporting a voltage range of 3.15V to 3.6V. The device features a parallel interface with a maximum access time of 10 ns and a write cycle time of 10 ns. It is housed in a 32-pin TSOP II surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Utilizes JEDEC center power and ground pinout architecture to reduce noise generation and improve system performance.
• Employs fully static asynchronous circuitry that eliminates the need for external clocks or periodic refresh cycles.
• Features LVTTL-compatible bidirectional inputs and outputs for direct interfacing with standard logic families.

Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded microcontroller architectures
• Industrial control equipment requiring wide temperature stability

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm the specific suffix PHGI8 matches the required 32-TSOP II package and industrial temperature grade. Check for moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure the design accommodates the specified 3.3V core voltage and LVTTL I/O levels.

Selection Notes

Select this component when a 128K x 8 organization is required with 10 ns speed at 3.3V. It is suitable for designs needing center VCC/GND pinouts for noise reduction. Compare against other 71V124 variants if different access times or package styles are needed. Ensure the application environment stays within the -40°C to +85°C operational limits.

Part Context

This part belongs to the Renesas 71V124 series of 3.3V CMOS SRAMs. The series offers various access speeds and packaging options to suit different system constraints. The 71V124SA variant specifically denotes the asynchronous operation mode with the center power/ground configuration.

Replacement Considerations

The manufacturer lists 71V124SA12TYGI as a recommended replacement. Verify compatibility regarding access time differences and package type changes before substitution.
