71V016SA20BFI

Overview

The IDT71V016SA20BFI is a 1-Mbit (64K x 16) asynchronous static random-access memory (SRAM) manufactured by Integrated Device Technology. It operates with a single 3.3V power supply and features a parallel interface. The device provides a maximum access time of 20 nanoseconds, ensuring efficient data retrieval for high-speed applications. It is housed in a 48-pin Ceramic Ball Grid Array (CABGA) package, designed for surface-mount technology. The component supports standard voltage ranges from 3.0V to 3.6V and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Asynchronous operation with a single 3.3V power supply
• High-speed parallel data access interface
• Industrial temperature range support
• Surface-mount CABGA packaging

Applications

• Embedded systems requiring non-volatile-like speed without retention
• Cache memory buffers in microprocessor-based designs
• Industrial control units operating in harsh environments
• Telecommunications equipment signal processing

Procurement Notes

Verify the specific suffix BFI confirms the 48-pin CABGA package configuration. Confirm RoHS compliance status as older IDT SRAMs may vary. Check for end-of-life notifications or obsolescence notices from Renesas Electronics, as IDT products are often discontinued or superseded by newer generations. Ensure availability matches current manufacturing cycles.

Selection Notes

Select this component when a 64K x 16 organization is required with 20ns access speed. Compare against faster variants like the SA12 if higher performance is needed. Consider package constraints; the CABGA form factor requires specific PCB footprint design. Evaluate thermal management requirements for the CABGA package in enclosed industrial enclosures.

Part Context

This part belongs to the IDT 71V016 family of 1-Mbit SRAMs. Variants differ primarily in access speed (e.g., 10ns, 12ns, 15ns, 20ns) and package type (TSOP, PQFP, CABGA). The 'SA' designation typically indicates standard asynchronous operation. The manufacturer IDT was acquired by Renesas Electronics, affecting long-term support channels.

Replacement Considerations

Check for direct pin-compatible upgrades within the 71V016 series with faster speeds (e.g., SA12). Verify equivalent parts from other manufacturers offering 64Kx16 async SRAM in CABGA-48 packages. Ensure voltage levels and timing parameters match the existing system design.
