7132SA100L48B

Overview

The 7132SA100L48B is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device supports parallel interface communication with an access time of 100 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and is housed in a 48-lead leaded ceramic dual-in-line package (LCC). The component is designed for asynchronous operation and is suitable for industrial temperature ranges.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate masters
• Asynchronous operation mode for flexible system integration
• Parallel data interface for standard memory bus compatibility

Applications

• Industrial control systems requiring isolated data buffering
• Embedded applications needing concurrent processor and peripheral access
• Automotive electronics utilizing robust ceramic packaging

Procurement Notes

Verify the specific suffix L48B against official Renesas documentation to confirm the leaded ceramic package variant. Confirm RoHS compliance status as older SRAM variants may differ. Check for active production or last-time-buy notices via manufacturer channels before procurement planning.

Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. Ensure the system design accommodates the 4.5V to 5.5V supply requirement. Verify that the 48-pin LCC footprint fits the target PCB layout constraints.

Part Context

This part belongs to the 7132SA series of dual-port SRAMs. These devices are engineered for high-reliability applications where simultaneous read/write operations from different controllers are necessary.
