7143LA20PF

Overview

The Renesas Electronics Corporation 7143LA20PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 32 kilobits organized as 2K words by 8 bits. The device supports parallel interface communication with an access time and write cycle time of 20 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm, designed for surface-mount installation. It functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• True dual-ported architecture enabling simultaneous independent access to the same memory location from both ports without conflict.
• On-chip port arbitration logic manages bus contention automatically, eliminating the need for external discrete control circuitry.
• Asynchronous operation allows flexible timing integration into various system architectures without requiring a global clock signal.
• Supports battery backup mode with data retention down to 2V, ensuring non-volatile data preservation during main power loss.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring simultaneous multi-port access
• Industrial automation controllers needing reliable volatile storage

Procurement Notes

Verify RoHS compliance status carefully, as specific suffixes or manufacturing dates may indicate non-compliant variants. Confirm package authenticity against official Renesas markings. Check for obsolescence notices or last-time-buy notifications before finalizing procurement plans due to potential discontinuation risks associated with legacy SRAM lines.

Selection Notes

Select this component when true dual-port capability is required for concurrent read/write operations. Ensure the 2Kx8 organization fits the application's data width requirements. Verify that the 20ns speed meets the system timing constraints. Consider the 64-TQFP package availability and thermal characteristics for the target PCB design environment.

Part Context

This part belongs to the IDT/Renesas 7143 series of dual-port SRAMs, which are widely used in applications requiring high-bandwidth data sharing between two processors or peripherals. The series offers various speed grades and package options to accommodate different performance and form-factor needs in industrial and commercial electronics.

Replacement Considerations

IDT7143LA20PF is a direct equivalent part number under the Integrated Device Technology brand prior to acquisition. Verify pinout compatibility and electrical specifications match exactly before substitution. No other cross-compatible parts are confirmed in the provided documentation.
