Memory IC Overview

The 709279L15PFI8 is a synchronous dual-port SRAM with a 512Kb capacity organized as 32K x 16 bits. It features a parallel interface and a 15 ns access time, operating within a 4.5V to 5.5V supply range. The device is housed in a 100-TQFP (14x14) surface-mount package and supports an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

Supports simultaneous independent access to the same memory location by both ports
Enables depth expansion through dual chip enable inputs without external logic
Provides separate upper-byte and lower-byte controls for bus matching compatibility

Memory IC Applications

High-speed data buffering in burst transfer systems
Bidirectional data flow applications requiring unidirectional or bidirectional support
Systems requiring simultaneous read/write operations on shared memory locations

Memory IC Procurement Notes

Verify component status as obsolete before procurement planning. Confirm RoHS compliance requirements against specific project standards due to non-compliant status. Validate package dimensions and moisture sensitivity level (MSL 3) against assembly capabilities. Ensure supply chain sources provide authentic documentation for this discontinued part number.

Memory IC Selection Notes

Select this component for designs requiring synchronous dual-port operation with 15 ns latency. Compare against asynchronous alternatives if clock synchronization is not feasible. Verify voltage tolerance matches the 4.5V to 5.5V specification. Consider thermal performance within the -40°C to +85°C range for industrial environments.

Memory IC Part Context

This part belongs to the Renesas 709279 series of high-speed synchronous dual-port RAMs. It is designed for applications optimized for burst data flows. The series offers pipelined or flow-through output modes selectable via hardware pins, providing flexibility for different system timing requirements.
