72221L15PF

Overview

The Renesas Electronics Corporation 72221L15PF is a synchronous First-In, First-Out (FIFO) memory device. It features a storage capacity of 1K x 9 bits, providing a total density of 9 kilobits. The component supports unidirectional data transfer with a maximum data rate of 66.7 MHz and an access time of 10 ns. It operates within a supply voltage range of 3 V to 3.6 V and draws a maximum supply current of 30 mA. The device is housed in a 64-LQFP package.

Feature Summary

• Synchronous FIFO architecture with clocked read and write controls for reliable data buffering
• Supports dual-clock operation where read and write clocks run asynchronously or single-clock operation
• Includes programmable flags to indicate full, empty, and almost-full conditions
• Features Full-When-Full (FWFT) capability to prevent data loss during buffer transitions

Applications

• Graphics data buffering systems
• Local area network interface buffers
• Interprocessor communication links

Procurement Notes

Verify the specific suffix 'PF' against official Renesas documentation to confirm pinout and package dimensions. Confirm RoHS compliance status as sources vary. Check for moisture sensitivity level requirements before handling. Ensure the 3V to 3.6V operating range matches the target system power rails. Validate lead-free status if required by assembly specifications.

Selection Notes

Select this component when a 1K x 9 synchronous FIFO is required for 3.3V logic interfaces. It is suitable for applications needing 66.7 MHz throughput with programmable status flags. Compare against the 72V215 series for similar functionality in different packages. Ensure the 64-pin LQFP footprint fits the design constraints. Verify that the unidirectional bus architecture meets the data flow requirements.

Part Context

The 72221L15PF belongs to the IDT 72V221 family of synchronous FIFOs manufactured by Renesas Electronics. This family provides high-speed data buffering solutions for digital systems. The device is designed to interface between processors and peripherals operating at different speeds. It serves as a critical component in data acquisition and signal processing chains.

Replacement Considerations

The 72V221L15J is a documented alternative within the same product family. Verify pin compatibility and electrical specifications before substitution.
