Overview
The 7132LA70JI8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 70 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-lead Plastic Leadless Chip Carrier (PLCC) package measuring 19.13mm x 19.13mm. The component is rated for an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual-port architecture enabling independent simultaneous access from two separate processors or systems.
Applications
- High-speed data buffering between asynchronous logic blocks
- Cache memory implementation in embedded processing systems
- Data storage in telecommunications equipment requiring parallel interfaces
Procurement Notes
Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt, ensuring no pin damage in the PLCC housing. Check manufacturing date codes against project timelines given potential supply constraints.
Selection Notes
Select this component when dual-port functionality is required for concurrent read/write operations. Ensure system voltage aligns with the 4.5V to 5.5V specification. Verify PCB layout compatibility with the 52-PLCC footprint. Consider thermal management for the specified industrial temperature range.
Part Context
This part belongs to the Renesas 7132LA series of dual-port SRAMs. It shares architectural similarities with other members like the 7134LA but differs in density and speed grades. The 'J' suffix typically denotes the plastic leadless chip carrier package variant.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer resources for cross-reference information.
