Overview
The AS7C1025C-15JIN is a 1 Mbit asynchronous static random access memory (SRAM) device manufactured by Alliance Memory, Inc. It features a 128K x 8 memory organization with a parallel interface. The component operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power supply current of 90 mA. It supports an access time of 15 ns and functions reliably across an industrial temperature range from -40°C to +85°C. The device is housed in a 32-pin Small Outline J-Lead (SOJ) package designed for surface mount technology.
Feature Summary
- Provides fast asynchronous data access via a parallel interface
- Operates on standard 5V logic levels for compatibility
- Designed for reliable performance in industrial temperature environments
Applications
- Industrial control systems requiring non-volatile backup support
- Embedded systems needing fast local data storage
- Telecommunications equipment buffer memory
Procurement Notes
Verify the specific suffix 'JIN' corresponds to the SOJ-32 tube packaging and industrial temperature grade. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure design-in reviews account for the 5V supply requirement and 90 mA maximum current consumption limits during peak operation.
Selection Notes
Select this component when a 1 Mbit capacity with 15 ns speed is required in a 32-pin SOJ package. It serves as a direct replacement for older AS7C1025B variants where industrial temperature ratings are mandatory. Consider pinout compatibility and voltage levels against existing circuit designs to ensure seamless integration without level shifting requirements.
Part Context
This part belongs to the AS7C1025 series of high-performance CMOS SRAMs. It represents the C-generation update to the B-series, maintaining functional compatibility while potentially offering improved manufacturing processes. The series is widely used in legacy system upgrades and new designs requiring robust, fast volatile memory solutions.
Replacement Considerations
The AS7C1025B-15JIN is a confirmed predecessor with identical electrical specifications and pinout. Verify that the B-series substitution meets all industrial temperature and voltage requirements if sourcing alternatives.
