70P249L90BYGI8

Memory IC Overview

The 70P249L90BYGI8 is a low-power dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 64 kbit organized as 4K x 16 bits. The device supports asynchronous parallel interfaces with a maximum access time of 90 ns. It operates within a voltage range of 1.8 V to 3.6 V and draws a maximum supply current of 70 mA. The component is housed in a 100-pin TFBGA package and functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access for two processors
• Low-power operation suitable for battery-constrained applications
• Asynchronous interface for flexible system integration

Memory IC Applications

• Telecommunications equipment requiring high-speed data buffering
• Industrial control systems needing reliable temporary storage
• Network infrastructure devices utilizing dual-processor architectures

Memory IC Procurement Notes

Verify the specific suffix 'BYGI8' against official Renesas documentation to confirm pinout, package dimensions, and moisture sensitivity level. Ensure compatibility with existing PCB footprints and reflow profiles. Confirm end-of-life status and long-term availability through authorized distributors before finalizing design-in decisions.

Memory IC Selection Notes

Select this component when a small-capacity, low-power dual-port SRAM is required for asynchronous data sharing between two masters. The 90 ns speed suits moderate-frequency applications. Compare against higher-speed variants if latency is critical, or single-port alternatives if cost reduction is prioritized over concurrent access capabilities.

Memory IC Part Context

This part belongs to the 70P249 series of low-power dual-port SRAMs. It shares architectural similarities with other members like the 70V24 series but differs in operating voltage and package options. The 70P249 series is designed for applications demanding reduced power consumption while maintaining dual-port functionality.
