7204L35J8

Overview

The 7204L35J8 is an asynchronous FIFO memory component manufactured by Renesas Electronics. It features a storage capacity of 36K bits, organized as 4K words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 22.22MHz and an access time of 35ns. It operates within a supply voltage range of 4.5V to 5.5V and is housed in a 32-PLCC package. The part is classified as obsolete.

Feature Summary

• Supports asynchronous read and write operations for independent clock domains
• Includes retransmit capability to reset the read pointer
• Provides status flags for empty, half-full, and full conditions

Applications

• Multiprocessing systems requiring data buffering
• Rate matching between different speed components
• Data acquisition systems

Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Availability is restricted to existing stock or surplus markets. Verify RoHS compliance status, as the datasheet indicates non-compliance. Confirm moisture sensitivity level and handling requirements before procurement.

Selection Notes

Select this part only if legacy compatibility with the 7204 series is required. Consider the 7204L12JG8 as a verified upgrade alternative. Evaluate current lead times and obsolescence risks associated with discontinued memory components for long-term production viability.

Part Context

The 7204L35J8 belongs to the 7200 series of CMOS FIFO memories. It is designed for applications needing high-speed data buffering without complex control logic. The device utilizes standard TTL-compatible I/O levels and offers expandability in word depth and bit width within its family.

Replacement Considerations

The 7204L12JG8 is listed as a verified upgrade replacement for the 7204L35J8. Verify pinout and functional compatibility before substitution.
