72205LB10PF

Overview

The Renesas Electronics Corporation 72205LB10PF is a synchronous FIFO memory device belonging to the 7200 series. It features a storage capacity of 4.5K bits, organized as 256 words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 100MHz and an access time of 6.5ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is housed in a 64-TQFP package measuring 14x14mm and is designed for surface mount installation. It functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for end-of-life notices or obsolescence warnings prior to procurement. Ensure packaging specifications match design requirements. Validate moisture sensitivity levels for proper handling and storage procedures.

Selection Notes

Select this component when a 256 x 18 bit synchronous FIFO is required. Ensure system voltage aligns with the 4.5V to 5.5V operating range. Verify that the 64-TQFP package fits the PCB layout constraints. Consider the 100MHz speed requirement against system timing needs. Evaluate thermal management capabilities for the specified temperature range.

Part Context

This part belongs to the IDT/Renesas 72205LB10 family of synchronous FIFOs. Similar variants include different capacities or packages within the same series. The 72205LB10PF specifically denotes the 256x18 configuration in TQFP packaging. Other family members may offer wider data buses or deeper memory depths while maintaining similar interface characteristics.

Replacement Considerations

Consult official datasheets for pin-compatible alternatives within the 72205LB10 series. Verify electrical parameters match original specifications before substitution. Check for updated manufacturing sources if the original part is discontinued.
