70P249L65BYGI

Memory IC Overview

The Renesas 70P249L65BYGI is a low-power dual-port static random-access memory (SRAM) IC. It features a storage capacity of 64 kbit, organized as 4K x 16 bits. The device supports parallel asynchronous interfaces with a maximum access time of 65 ns. It operates within a supply voltage range of 1.8 V to 3.3 V and is housed in a 100-pin CABGA package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access for two processors or systems
• Automatic power-down feature controlled by chip select signals for low standby power consumption
• Asynchronous operation compatible with standard parallel interface protocols

Memory IC Applications

• High-speed data buffering between asynchronous system components
• Cache memory implementation in embedded processing systems
• Data logging applications requiring non-volatile-like persistence during power cycles

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status and lead-free specifications prior to integration. Check for moisture sensitivity level requirements and appropriate handling procedures during assembly. Ensure the specific suffix matches design requirements for temperature and packaging variations.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations without external arbitration logic. Consider the 65 ns access speed and 1.8 V to 3.3 V operating range for compatibility with mixed-voltage systems. Evaluate the 100-pin CABGA package constraints against available board space and thermal management capabilities.

Memory IC Part Context

This part belongs to the Renesas 70P2xxL series of low-power dual-port SRAMs. It shares architectural similarities with other members like the 70P259L65BYGI but differs in density and organization. The series is designed for applications requiring high-speed data sharing between independent bus masters.

Memory IC Replacement Considerations

Direct substitutes include the IDT70P249 from Integrated Device Technology, which offers identical electrical characteristics and pinout compatibility. Verify that any replacement maintains the same 4K x 16 organization and 65 ns access time.
