7132LA100PDG

Memory IC Overview

The Renesas Electronics Corporation 7132LA100PDG is a dual-port static random access memory (SRAM) device. It features a storage capacity of 16 kbit organized as 2K x 8 bits. The component supports parallel interface communication with an access time of 100 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 110 mA. The device is designed for through-hole installation in a tube package. It functions reliably within an operating temperature range from 0°C to +70°C.

Memory IC Feature Summary

• True dual-ported memory cells enabling simultaneous independent access to the same memory location by two processors.
• Asynchronous operation from either port, allowing flexible integration into multi-processor systems without clock synchronization requirements.
• Automatic power-down feature controlled by chip enable signals, permitting on-chip circuitry to enter low standby power mode.

Memory IC Applications

• Stand-alone 8-bit dual-port RAM applications
• Master/Slave dual-port configurations for expanding data bus width to 16 bits or more
• Interprocessor communications requiring battery backup operation

Memory IC Procurement Notes

Verify component authenticity and datasheet revision status due to end-of-life designation. Confirm RoHS compliance details as specifications may vary by manufacturing date. Check for alternative lead-free packages if required by current assembly standards. Validate pinout compatibility with existing PCB layouts before procurement.

Memory IC Selection Notes

Select this part when asynchronous dual-port memory is required for 8-bit systems. Ensure the 100 ns access time meets system timing constraints. Verify that the 4.5V to 5.5V supply voltage aligns with the target platform. Consider the 48-PDIP package dimensions for mechanical fit. Evaluate thermal performance within the 0°C to +70°C industrial range.

Memory IC Part Context

This component belongs to the IDT/Renesas 7132 series of high-speed dual-port SRAMs. It is often paired with the 7142 series slave devices to create wider data buses. The LA suffix indicates specific battery backup capabilities retaining data down to 2V. The PDG suffix denotes the plastic dual in-line package variant.
