7140LA55PF

Memory IC Overview

The Renesas Electronics Corporation 7140LA55PF is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features a parallel interface with a maximum access time of 55 nanoseconds and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a 64-pin Thin Quad Flat Pack (TQFP) package measuring 14x14 mm. The component supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on two separate ports.

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data acquisition systems requiring fast parallel access

Memory IC Procurement Notes

Verify the specific suffix 'PF' against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for product discontinuance notices or end-of-life announcements prior to finalizing procurement plans.

Memory IC Selection Notes

Select this component when a small-capacity, high-speed dual-port SRAM is required for applications needing independent port access. Ensure the design accommodates the 64-TQFP surface-mount package constraints. Verify that the 55ns access speed meets system timing requirements and that the 4.5V to 5.5V supply voltage aligns with the target platform's power rails.

Memory IC Part Context

This part belongs to the Renesas 7140 series of asynchronous dual-port SRAMs. These devices are designed for applications requiring high-speed data transfer between two independent systems or processors. The series typically offers various access speeds and packaging options to suit different density and form factor needs.

Memory IC Replacement Considerations

Consult official Renesas datasheets for verified cross-reference part numbers. Ensure any substitute maintains identical dual-port functionality, 8Kb capacity, 55ns access time, and 64-TQFP package compatibility.
