70T651S15DR

Memory IC Overview

The 70T651S15DR is a 9-Mbit dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It features a memory organization of 256K x 36 bits and utilizes a parallel interface with asynchronous operation. The component supports a supply voltage range of 2.4V to 2.6V and offers an access time of 15 ns. It is housed in a 208-pin PQFP surface-mount package with dimensions of 28x28 mm. The device operates within a temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location from two separate ports.
• Asynchronous operation allowing flexible timing control without reliance on a global clock signal.
• Parallel interface supporting high-speed data transfer for complex system integration.

Memory IC Applications

• High-performance computing systems requiring fast data buffering
• Network infrastructure equipment needing low-latency memory access
