7207L20JGI8

Overview

The Renesas Electronics Corporation 7207L20JGI8 is an asynchronous first-in, first-out (FIFO) memory device with a capacity of 32K x 9 bits. It operates on a single 5.0V power supply within a voltage range of 4.5V to 5.5V. The component features a 20ns access time and utilizes a parallel interface for data transfer. It is housed in a 32-pin PLCC package and supports surface-mount installation. The device includes status flags such as Empty, Half-Full, and Full to manage data flow.

Feature Summary

• Supports asynchronous and simultaneous read and write operations
• Includes auto-retransmit capability for pointer reset
• Provides hardware status flags to prevent overflow and underflow

Applications

• Multiprocessing systems requiring rate buffering
• Data acquisition systems needing temporary storage
• Digital signal processing interfaces

Procurement Notes

Verify the specific suffix JGI8 against official datasheets to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as documentation indicates variations. Check current availability as the part may be discontinued or subject to limited supply constraints from authorized distributors.

Selection Notes

Select this component when a unidirectional FIFO with 9-bit word width is required. Ensure the design accommodates the 32-pin PLCC footprint and 5V logic levels. Verify that the 20ns speed meets system timing requirements compared to faster alternatives like the L15 variant.

Part Context

This part belongs to the 7207L20 series of CMOS parallel FIFO memories. It is functionally compatible with other devices in the 720X family, allowing for pin-compatible upgrades or replacements within existing designs that utilize similar asynchronous memory architectures.

Replacement Considerations

The IDT7207L20JGI8 is listed as an alias. For active alternatives, consider the 7207L15JGI8 which offers faster 15ns access times while maintaining the same package and functionality.
