Overview
The AS7C1026B-15JIN is a 1 Mbit (64K 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 of 210 mA. The device features a 15 ns access time and supports parallel interface communication. It is housed in a 44-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology. The component is rated for an industrial operating temperature range from -40°C to +85°C.
Feature Summary
- Provides high-speed asynchronous data access with a 15 ns cycle time for efficient system integration.
- Utilizes a 44-pin SOJ surface-mount package to facilitate compact circuit board layouts.
- Supports industrial-grade thermal stability across a wide temperature spectrum.
Applications
- Industrial control systems requiring reliable non-volatile-like temporary storage
- Embedded computing architectures utilizing parallel memory interfaces
- Automotive electronics operating under strict environmental conditions
Procurement Notes
Verify the specific suffix 'JIN' against the manufacturer's current datasheet to confirm pinout compatibility and packaging details. Ensure that the 4.5 V to 5.5 V supply voltage requirements align with the target system design. Confirm that the 44-pin SOJ form factor matches the printed circuit board footprint constraints before finalizing procurement decisions.
Selection Notes
Select this component when a 64K x 16 organization is required for parallel data processing applications. The 15 ns speed class suits systems needing moderate-to-high throughput without complex clock synchronization. Consider the SOJ package availability and industrial temperature rating as primary selection criteria over commercial grade alternatives.
Part Context
This part belongs to the AS7C1026B series of fast asynchronous SRAMs. It offers a 1 Mbit capacity organized as 64K words by 16 bits. The series is designed for general-purpose memory applications where low standby power and fast access times are critical for system performance.
Replacement Considerations
Check for AS7C1026B-15TIN if TSOP-II packaging is preferred. Verify AS7C1026C-15JIN for potential next-generation revisions, though functional equivalence must be confirmed via official documentation.
