7132LA20PDG

Memory IC Overview

The Renesas Electronics Corporation 7132LA20PDG is a 16Kbit (2K x 8) dual-port asynchronous static random-access memory (SRAM). It operates within a supply voltage range of 4.5V to 5.5V and features a parallel interface with a maximum access time of 20ns. The component is housed in a 48-pin Plastic Dual In-line Package (PDIP) designed for through-hole mounting. It supports single data rate storage and functions reliably across an operating temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation without requiring external clock signals
• CMOS technology ensuring low power consumption during standby and active states

Memory IC Applications

• Embedded systems requiring shared memory resources between multiple controllers
• Industrial control units needing fast, non-volatile-like temporary data buffering
• Telecommunications equipment utilizing parallel data processing architectures

Memory IC Procurement Notes

Verify the specific suffix PDG confirms the 48-PDIP package type, as other suffixes indicate different form factors. Confirm RoHS compliance status for current manufacturing lots, as legacy components may have varying environmental declarations. Check for official End-of-Life notices or Product Change Notifications that may affect long-term availability or sourcing strategies for this discontinued series.

Memory IC Selection Notes

Select this component when a design requires true dual-port capability for concurrent read/write operations from separate buses. Ensure the PCB layout accommodates the 48-PDIP footprint and through-hole assembly processes. Verify that the system logic levels align with the 5V nominal supply requirements and that the 20ns access speed meets the timing constraints of the host processor interface.

Memory IC Part Context

This device belongs to the IDT/Renesas 7132LA family of dual-port SRAMs. It shares architectural similarities with the 7132SA variant but differs in package and speed options. The LA series typically denotes specific commercial grade temperature ranges and packaging styles distinct from industrial or automotive qualified counterparts within the broader memory portfolio.

Memory IC Replacement Considerations

Official substitutes include the 7132LA20JG (PLCC package) and 7132LA35PDG (slower 35ns speed). Cross-reference pinouts carefully when substituting packages like PLCC or TQFP, as physical footprints differ significantly from the PDIP form factor.
