709279L15PF8

Memory IC Overview

The 709279L15PF8 is a high-speed 512Kb (32K x 16) synchronous dual-port static random-access memory manufactured by Renesas Electronics. It operates on a single 5V TTL-compatible power supply with a voltage range of 4.5V to 5.5V. The device features a parallel interface and supports data rates up to 50MHz, corresponding to a 15ns access time. It is housed in a 100-pin TQFP package measuring 14x14mm. The component supports both flow-through and pipelined output modes, selectable via the FT/PIPE pin, and includes automatic power-down capabilities controlled by CE0 and CE1 pins.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to the same memory location from two separate ports.
• Configurable output mode allows selection between flow-through and pipelined operations for optimized data throughput.
• Automatic power-down feature reduces standby power consumption when chip enable signals are inactive.
• Supports depth expansion through dual chip enable inputs without requiring additional external logic.

Memory IC Applications

• High-speed burst data transfer systems requiring unidirectional or bidirectional data flow
• Network infrastructure equipment utilizing parallel bus architectures
• Industrial control systems needing low-latency memory access
