Overview
The AS7C1026C-15JIN is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption current of 210 mA. The device features a 15 ns access time and supports parallel interface communication. It is designed for surface-mount installation in a 44-pin SOJ package. The component functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Provides high-speed asynchronous data access with a 15 ns cycle time for rapid read operations.
- Supports wide 16-bit data organization suitable for complex digital signal processing tasks.
- Operates on standard 5V logic levels compatible with general-purpose microprocessor systems.
Applications
- Industrial control systems requiring robust memory under varying environmental conditions
- Embedded applications utilizing 16-bit data buses for efficient information handling
- High-performance computing modules needing fast asynchronous storage solutions
Procurement Notes
Verify the specific suffix JIN confirms the SOJ-44 package type and industrial temperature rating during acquisition. Confirm RoHS compliance status through official documentation before integration. Ensure design compatibility with 5V logic levels and 16-bit bus architectures. Check for end-of-life notices as manufacturing status may affect long-term availability.
Selection Notes
Select this component when a 16-bit data width is required for system architecture efficiency. Choose this part for designs operating strictly within 5V power constraints. Consider this option for applications demanding reliable performance across extended industrial temperature ranges. Verify pinout compatibility with existing PCB layouts featuring 44-pin SOJ footprints.
Part Context
This SRAM belongs to the AS7C1026C series, representing a generation of high-density memory solutions. It serves as a critical storage element in legacy and specialized electronic designs. The component bridges the gap between smaller capacity chips and faster synchronous memories. Its asynchronous nature allows flexible timing control in diverse processor environments.
Replacement Considerations
AS7C1026B-15JIN offers similar specifications with potential minor electrical differences. AS7C1026C-15TIN provides identical functionality but utilizes a TSOP-II-44 package instead of SOJ-44. Verify pin compatibility and thermal characteristics when substituting these alternatives.
