7140LA35PF

Memory IC Overview

The Renesas 7140LA35PF 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 parallel interface access with a maximum access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 64-TQFP package measuring 14x14 mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Memory IC Feature Summary

Supports simultaneous independent read/write operations by two separate bus masters
Provides high-speed asynchronous data transfer via parallel interface
Utilizes CMOS technology for low power consumption

Memory IC Applications

Network router buffer memory
Telecommunications equipment caching
Industrial control system data logging

Memory IC Procurement Notes

Verify the specific suffix 'PF' to confirm the 64-TQFP package variant, as other suffixes indicate different form factors. Confirm RoHS compliance status, as older batches may not meet current environmental standards. Check for End-of-Life (EOL) or Last Time Buy notices from the manufacturer before finalizing procurement plans.

Memory IC Selection Notes

Select this component when concurrent dual-port access is required for 8K-bit data buffering. Ensure the design accommodates the 64-lead TQFP footprint and 35ns timing constraints. Verify that the system logic levels match the 4.5V to 5.5V supply requirements without additional level shifting.

Memory IC Part Context

This part belongs to the IDT 7140LA series of dual-port SRAMs. It shares architectural similarities with other variants like the 7140LA35J8 but differs in packaging. The series is designed for applications requiring high-speed data exchange between processors or peripherals without complex arbitration logic.
