71421LA35PF8

Overview

The 71421LA35PF8 is a high-speed dual-port asynchronous SRAM manufactured by Renesas Electronics Corporation. It provides a storage capacity of 16Kb, organized as 2K x 8 bits. The device features a parallel interface with a maximum access time and write cycle time of 35 ns. It operates within a supply voltage range of 4.5V to 5.5V and supports surface mount installation in a 64-TQFP (14x14) package. The component is designed for interprocessor communications and includes internal interrupt logic.

Feature Summary

Dual-port architecture enabling simultaneous independent access by two processors
Internal interrupt logic facilitates efficient interprocessor communication
Asynchronous operation allows flexible timing integration
Low standby power mode controlled by chip enable signals

Applications

Interprocessor communication systems
Master-slave dual-port memory configurations
High-speed data buffering applications

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package dimensions against PCB footprint specifications before procurement. Check for available upgrade alternatives from the manufacturer if long-term supply stability is required.

Selection Notes

Select this component for designs requiring independent dual-port access without external arbitration logic. Ensure system voltage levels align with the 4.5V to 5.5V operating range. Consider the 64-TQFP package constraints during layout planning. Evaluate thermal performance within the specified commercial temperature range for reliable operation.

Part Context

This part belongs to the 71421 series of dual-port SRAMs. It functions primarily as a slave device in 16-bit or wider systems when paired with compatible master controllers. The series is engineered for full-speed error-free operation without additional discrete logic components.
