7132LA45PDG

Overview

The Renesas Electronics Corporation 7132LA45PDG is a dual-port, asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits organized as 2K words by 8 bits. The device features a parallel interface with a maximum access time of 45 nanoseconds and a write cycle time of 45 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial operating temperature range from 0°C to 70°C. The component is housed in a 48-pin Plastic Dual In-line Package (PDIP) with a lead pitch of 0.600 inches (15.24mm).

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on two separate ports.
• Asynchronous operation allowing flexible timing control without requiring a system clock signal.
• Parallel data interface supporting standard bus connections for high-speed data transfer.
• Surface-mount compatible through-hole packaging designed for reliable board integration.

Applications

• High-speed data buffering in telecommunications equipment.
• Cache memory implementation in embedded processing systems.
• Data storage in industrial automation controllers.
• Temporary storage in test and measurement instrumentation.

Procurement Notes

Verify the specific suffix PDG confirms the 48-PDIP package configuration, as other suffixes may indicate different form factors or speed grades. Confirm RoHS compliance status, as older production runs may differ from current specifications. Check for end-of-life notices, as this component family has faced discontinuation events. Ensure compatibility with existing PCB footprints before ordering replacement stock.

Selection Notes

Select this part when a dual-port asynchronous SRAM with 16Kb capacity is required. The 45ns speed grade suits applications needing moderate access times. The PDIP package is suitable for prototyping or legacy board designs requiring through-hole mounting. Compare against the 7132LA35PDG if faster 35ns performance is needed, or consider the 7134LA series for increased 32Kb density.

Part Context

This component belongs to the IDT 7132SA/LA family of dual-port SRAMs manufactured by Renesas Electronics. The 'LA' designation typically indicates commercial/industrial temperature ranges and specific speed grades. The 7132 series is widely used in networking and industrial applications requiring independent port access. This specific model represents the 45ns variant in the 16Kb density class.

Replacement Considerations

The 7132LA35PDG is a verified substitute offering identical pinout and functionality with improved 35ns speed. Verify that the higher speed does not violate setup/hold time requirements in the target design. Other family members like 7132SA variants may offer different environmental ratings but require electrical verification.
