7140SA35PF

Overview

The Renesas Electronics Corporation 7140SA35PF is a dual-port static random-access memory (SRAM) integrated circuit. It provides an 8-kilobit storage capacity organized as 1K words by 8 bits. The device utilizes a parallel interface with asynchronous operation and features a 35 nanosecond access time. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-pin PLCC package measuring 19.13mm by 19.13mm. The component functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

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

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation for microprocessors
• Real-time processing applications requiring low latency

Procurement Notes

Verify the exact suffix designation, as the provided model number references a TQFP package while official records indicate a PLCC package. Confirm RoHS compliance status, as specific variants may not meet current environmental standards. Check for end-of-life notifications or discontinuance notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a compact 8Kbit dual-port SRAM solution is required for parallel bus architectures. Ensure the design accommodates the 52-PLCC footprint and 5V logic levels. Consider thermal management requirements for the specified operating temperature range during system integration.
