7132SA55JI

Overview

The Renesas Electronics Corporation 7132SA55JI is a static random access memory (SRAM) device featuring a 16 kbit storage capacity organized as 2k x 8. It utilizes a parallel interface with an asynchronous architecture and offers a maximum access time of 55 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption of 155 mA. Designed for surface mount applications, it is housed in a 52-PLCC package. The device supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Dual-port asynchronous SRAM technology enabling independent simultaneous read/write operations on separate ports.

Applications

• Real-time data buffering in industrial control systems
• High-speed cache memory for embedded processors
• Data logging in automated test equipment

Procurement Notes

Verify the exact suffix 'J' against official Renesas documentation to confirm pinout compatibility and lead frame specifications. Confirm RoHS status, as older variants may not meet current environmental directives. Check for obsolescence notices or last-time buy deadlines directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for concurrent host and peripheral access to shared memory. Ensure the system design accommodates the 52-PLCC package dimensions and thermal requirements. Verify that the 5V logic levels align with the rest of the circuit's I/O standards.
