7142LA100J8

Overview

The 7142LA100J8 is a dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features an organization of 2K x 8 bits, providing a total storage capacity of 16 kilobits. The device operates with asynchronous parallel interfaces and supports a supply voltage range of 4.5V to 5.5V. It offers a maximum access time of 100 nanoseconds. The component is housed in a 52-pin Plastic Leadless Chip Carrier (PLCC) package with J-leads, measuring 19.0mm x 19.0mm. It functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports simultaneous independent access from two distinct ports for concurrent read/write operations
• Utilizes CMOS technology for low power consumption and high-speed asynchronous data transfer
• Integrates dedicated busy and slave I/O signals to manage arbitration between the two accessing ports

Applications

• High-performance embedded systems requiring concurrent data access
• Industrial control units needing reliable volatile memory storage
• Telecommunications equipment utilizing dual-port buffering architectures

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package dimensions against PCB footprint specifications before integration. Ensure supply chain stability given discontinued manufacturing status.

Selection Notes

Select this component when dual-port functionality is required for 16Kb memory applications. Compare access times and pin configurations against alternative SRAM families. Evaluate thermal performance within the specified operating temperature range. Consider package compatibility with existing surface-mount assembly processes.
