709379L12PF8

Memory IC Overview

The Renesas Electronics Corporation 709379L12PF8 is a high-speed synchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 576 kbit, organized as 32K x 18 bits. The component supports parallel interface operation with a maximum access time of 12 ns. It operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. The device is housed in a 100-pin TQFP surface-mount package and is designed for commercial temperature ranges from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to the same memory location by two separate controllers.
• Full synchronous operation on both ports ensures precise timing control for burst data flows.
• Automatic power-down feature controlled by chip enable signals allows entry into low standby power mode.

Memory IC Applications

• Applications requiring unidirectional or bidirectional data flow in bursts
• Systems utilizing multiplexed bus architectures
• Bus matching compatibility designs

Memory IC Procurement Notes

This component is officially listed as obsolete and discontinued by the manufacturer. Availability is restricted to existing stock or third-party distributors. Verify RoHS compliance status, as indicated sources show non-compliance. Confirm moisture sensitivity level and lead-free status prior to integration into new production designs due to end-of-life status.

Memory IC Selection Notes

Select this part only if specific 18-bit word width and synchronous dual-port functionality are required. Ensure design compatibility with 5V logic levels and 12 ns access speed requirements. Consider that the 100-pin TQFP package requires appropriate PCB footprint planning. Evaluate alternative components if current supply chain stability is critical for long-term manufacturing.

Memory IC Part Context

The 709379L12PF8 belongs to the 709379L series of synchronous dual-port SRAMs. This family is optimized for high-speed data transfer applications. The device integrates counter enable and reset features, along with dual chip enables for depth expansion without additional logic. It offers flow-through or pipelined output modes selectable via hardware pins.

Memory IC Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the device is obsolete, engineers must identify equivalent synchronous dual-port SRAMs with compatible pinouts, voltage levels, and access times through independent technical comparison.
