7143SA20PF8

Overview

The Renesas Electronics Corporation 7143SA20PF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 32Kb organized as 2K words by 16 bits. The device supports parallel interface operation with a maximum access time of 20 ns and a write cycle time of 20 ns. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. It is designed for industrial temperature ranges from 0°C to 70°C.

Feature Summary

• True dual-ported memory cells allow 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 logic in master/slave configurations.
• Versatile byte-level write control enables expansion of data bus width to 32 bits or more when multiple devices are connected.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in digital signal processing systems
• FIFO buffer applications in network switching hardware

Procurement Notes

Verify the specific suffix PF8 against official Renesas documentation to confirm package type and lead finish specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check current production status as legacy components may have limited availability or end-of-life notices. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Selection Notes

Select this component when simultaneous read/write access to shared memory is required without external arbitration logic. Choose the 20 ns speed grade for high-throughput applications requiring fast data retrieval. Verify that the 100-pin TQFP package fits your board layout constraints. Ensure the 5V supply voltage matches your system design and that the operating temperature range meets environmental requirements.

Part Context

The 7143SA series belongs to Renesas' portfolio of high-performance dual-port SRAMs, derived from IDT technology. These devices utilize CMOS technology to provide low power consumption while maintaining high speed. The 7143 variant specifically offers 32Kb density, distinguishing it from other densities in the family such as 16Kb or 64Kb options. The SA suffix typically denotes standard industrial temperature range variants.

Replacement Considerations

Official substitutes include the 7143LA20PF8, which shares identical electrical characteristics but may differ in temperature range or packaging details. Verify pin compatibility and functional equivalence before substitution. Cross-reference with IDT part numbers such as IDT7143SA20PF8 if sourcing from legacy distributors.
