70T651S12BFGI

Memory IC Overview

The Renesas Electronics Corporation 70T651S12BFGI is a dual-port static random-access memory (SRAM) device belonging to the 70T651 series. It features a storage capacity of 9 Mbit organized as 256K words by 36 bits. The component supports asynchronous parallel interface operation with a maximum access time of 12 ns. It operates within a supply voltage range of 2.4 V to 2.6 V and functions across an industrial temperature range from -40°C to +85°C. The device is housed in a 208-lead CABGA package measuring 15x15 mm, designed for surface-mount installation.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to shared memory locations by two separate ports.
• Asynchronous operation allowing flexible timing control without reliance on a global clock signal.
• Integrated hardware support for semaphore signaling to manage port contention and data integrity.
• Selectable power supply configuration supporting core voltage at 2.5V with LVTTL-compatible I/O levels.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring concurrent read/write operations.
• Network switch and router architectures utilizing interleaved I/O for packet processing.
• Industrial automation systems needing reliable memory interfaces under varying thermal conditions.
• Embedded computing platforms requiring low-latency access to critical system variables.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm package marking and date codes against official Renesas documentation. Ensure handling procedures account for moisture sensitivity level 3 requirements during soldering. Validate electrical parameters against specific datasheet revisions prior to integration into final designs.

Memory IC Selection Notes

Select this component when dual-port concurrency is required for high-throughput applications. Consider the 208-CABGA footprint for board layout constraints. Evaluate power consumption specifications against system thermal limits. Compare access times with alternative parts if stricter latency requirements exist. Verify compatibility with existing logic voltage levels for seamless interface integration.
