7282L12PAG

FIFOs Memory Overview

The Renesas 7282L12PAG is a dual asynchronous FIFO memory device featuring a 1K x 9 organization. It provides 18 Kbits of total storage capacity with a 9-bit data bus width to support parity checking. The component operates within a 4.5 V to 5.5 V supply range and supports clock frequencies up to 50 MHz. It offers an access time of 12 ns and functions in unidirectional mode. The device is housed in a 56-pin TSSOP package and is rated for industrial temperatures from -40°C to +85°C.

FIFOs Memory Feature Summary

• Dual independent first-in-first-out memory structures
• Asynchronous operation with dedicated read and write clocks
• 9-bit data path supporting even or odd parity generation and checking
• Unidirectional data flow control

FIFOs Memory Applications

• Data buffering between asynchronous logic domains
• Parity error detection in communication interfaces
• Interface matching between different speed components
• Temporary data storage in digital signal processing chains

FIFOs Memory Procurement Notes

Verify the obsolete status of this part number before design finalization. Confirm availability through authorized distributors as stock may be limited. Ensure the 56-TSSOP package footprint matches the target PCB layout. Validate that the 5V logic levels are compatible with the system voltage requirements.

FIFOs Memory Selection Notes

Select this component when dual independent FIFOs are required for asynchronous data transfer. The 9-bit width is suitable for applications needing hardware parity support. Verify that the 12 ns access time meets the system timing constraints. Consider the TSSOP-56 package size for space-constrained designs requiring surface mount technology.

FIFOs Memory Part Context

This device belongs to the Renesas 7200 series of high-speed FIFO memories. It is designed for general-purpose data buffering and protocol conversion tasks. The series is known for reliable asynchronous operation and flexible interface capabilities. This specific model represents an older generation component now classified as obsolete.

FIFOs Memory Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements must be verified against current Renesas product portfolios or equivalent offerings from other manufacturers.
