72V273L10PF

FIFOs Memory Overview

The 72V273L10PF is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 288 kbit, organized as 16K x 18 or 32K x 9. The component supports a maximum clock frequency of 66.7 MHz and offers an access time of 10 ns. It operates within a supply voltage range of 3.15 V to 3.45 V. The device is housed in an 80-pin TQFP package with dimensions of 14x14 mm.

FIFOs Memory Feature Summary

• Supports unidirectional data bus operation with configurable width options.
• Features independent read and write clocks allowing simultaneous operations.
• Includes programmable flags for empty, full, half-full, almost-empty, and almost-full states.

FIFOs Memory Applications

• Data buffering in high-speed digital signal processing systems
• Interface bridging between asynchronous logic components
• Temporary storage in telecommunications equipment

FIFOs Memory Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer channels. Buyers must confirm the authenticity of the part number alias IDT72V273L10PF when sourcing from third-party vendors. Ensure that the specific package variant matches design requirements due to potential legacy stock variations.

FIFOs Memory Selection Notes

Designers requiring this specific FIFO architecture should consider the functional compatibility with the 72V273 series. Since the original part is obsolete, alternative solutions must match the 288 kbit capacity and 80-pin TQFP form factor. Verify that replacement devices support the required 66.7 MHz clock speed and 3.3V operating voltage to maintain system integrity without redesigning the power supply or timing constraints.

FIFOs Memory Part Context

The 72V273L10PF belongs to the Renesas 72V273 SuperSync II FIFO family. This series is designed for high-performance applications requiring reliable data buffering. The device utilizes synchronous control signals for predictable timing behavior. It is functionally related to other parts in the 72V273 lineup, sharing similar interface characteristics and pinout configurations for ease of migration in existing designs.

FIFOs Memory Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult Renesas technical resources for current equivalent recommendations or evaluate generic synchronous FIFOs with matching electrical specifications and package dimensions.
