Overview
The 71V124SA15YG8 is a 3.3V CMOS asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 1 Mbit, organized as 128K words by 8 bits. The device offers a maximum access time of 15 ns and operates within a supply voltage range of 3.0 V to 3.6 V. It utilizes a parallel interface and is housed in a 32-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology.
Feature Summary
- Utilizes a JEDEC center power and ground pinout configuration to reduce noise generation and improve system performance.
- Employs fully static asynchronous circuitry that requires no clocks or refresh cycles for operation.
- Features LVTTL-compatible bidirectional inputs and outputs for direct interfacing with logic systems.
Applications
- High-performance processor secondary cache memory
- Industrial equipment control systems
- Embedded data storage applications
Procurement Notes
This component is classified as obsolete and has reached the end-of-life stage, meaning it will be discontinued by the manufacturer. Procurement should focus on verifying final availability through authorized distributors. Buyers must confirm lead times and minimum order quantities directly with suppliers, as stock levels are limited and subject to change without notice.
Selection Notes
Select this part when a 1 Mbit asynchronous SRAM with 15 ns speed is required in a 32-pin SOJ package. Ensure the design supports a single 3.3V supply and LVTTL logic levels. Verify that the center power/ground pinout aligns with the PCB layout requirements for noise reduction.
Part Context
The 71V124SA15YG8 belongs to the 71V124 series of 3.3V CMOS SRAMs. This family is characterized by its low power consumption via chip deselect and compatibility with standard logic families. The specific suffix indicates the 15 ns speed grade and the 32-pin SOJ packaging option.
Replacement Considerations
Verify cross-reference part numbers such as IDT71V124SA15Y8 for potential functional equivalence. Confirm that any substitute matches the 128K x 8 organization, 15 ns access time, and 32-pin SOJ physical dimensions before integration.
