7140LA20JG8

Overview

The 7140LA20JG8 is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. 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 20 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports a commercial operating temperature range from 0°C to 70°C. The component is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access for two processors or systems
• Asynchronous operation allowing flexible timing integration without external clock synchronization
• Parallel data interface supporting standard 8-bit word width connections

Applications

• High-speed data buffering between asynchronous logic blocks
• Cache memory implementation in embedded processing systems
• FIFO buffer applications requiring independent read/write ports

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS3 compliance and moisture sensitivity level requirements during handling. Check for valid manufacturer documentation to ensure pinout compatibility with existing designs. Validate that the PLCC package dimensions match the target PCB footprint specifications before procurement.

Selection Notes

Select this component when dual independent access is required for small-capacity volatile memory. Ensure the design accommodates the 52-pin PLCC package constraints. Verify that the 20ns access speed meets system timing requirements. Confirm power supply stability within the specified voltage range for reliable operation across the commercial temperature spectrum.
