7281L20PAG8

FIFOs Memory Overview

The 7281L20PAG8 is an asynchronous FIFO memory component manufactured by Renesas Electronics. It features a storage capacity of 4.6K bits, organized as 256 words by 9 bits in a dual configuration (256 x 9 x 2). The device supports data rates up to 50MHz with a maximum access time of 12ns. It operates within a supply voltage range of 4.5V to 5.5V and has a maximum supply current of 125mA. The unit is housed in a 56-TSSOP surface-mount package and functions bidirectionally. It is designed for industrial temperature ranges from 0°C to 70°C.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface timing.
• Bidirectional bus direction capability enables efficient data transfer across varying system architectures.
• Programmable flags support status monitoring for full and empty conditions without constant polling.

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• High-speed data acquisition systems requiring temporary storage

FIFOs Memory Procurement Notes

Verify the specific suffix 'PAG8' against official Renesas documentation to confirm the tape-and-reel packaging format. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as legacy components may have varying environmental declarations. Ensure the supplier provides valid traceability documents for this discontinued series part number.

FIFOs Memory Selection Notes

Select this component when asynchronous decoupling is required between logic blocks with mismatched clock frequencies. The 9-bit width suits applications handling non-standard data buses or parity-enabled communication protocols. Verify that the 56-pin TSSOP footprint aligns with existing PCB layout constraints before finalizing the design integration.

FIFOs Memory Part Context

This device belongs to the Renesas 7200 series of high-performance FIFO memories. It serves as a bridge solution for legacy parallel interfaces. The part represents a transition component in the company's memory portfolio, offering moderate density with low power consumption characteristics suitable for embedded control applications.

FIFOs Memory Replacement Considerations

Public records indicate IDT7281L20PAG8 as an alias for this component. Verify pin compatibility and electrical specifications before substituting with other asynchronous FIFO families. Consult Renesas engineering support for validated cross-reference options if the original part is unavailable.
