7132LA20PDGI

Overview

The Renesas Electronics Corporation 7132LA20PDGI is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kbit, organized as 2K words by 8 bits. The device features a parallel interface with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 48-pin plastic dual in-line package (PDIP). The component is designed for commercial temperature applications ranging from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation without clock synchronization requirements
• Parallel data interface for direct system bus connectivity

Applications

• Embedded systems requiring shared memory resources
• Industrial control units with multi-processor architectures
• Telecommunications equipment buffer memory

Procurement Notes

Verify the specific suffix PDGI against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for active production status or obsolescence notices. Ensure the supplier provides valid traceability documents. Validate that the component meets the required operating temperature range for the target application environment.

Selection Notes

Select this component when a dual-port SRAM solution is required for asynchronous data sharing between two masters. The 16Kbit capacity suits small buffer applications. The 20 ns speed is suitable for moderate-frequency microcontrollers. The PDIP package is appropriate for prototyping or through-hole manufacturing processes. Verify power consumption limits against system constraints.

Part Context

This part belongs to the Renesas 7132 series of dual-port SRAMs. It shares architectural similarities with other members like the 7132LA20JG but differs in package type. The series is characterized by CMOS technology and standard parallel interfaces. It serves as a legacy component in embedded memory design portfolios.

Replacement Considerations

The 7132LA20JG is an alternative package variant within the same functional family. Verify pin-to-pin compatibility before substitution. Other series members may offer different capacities or speeds.
