Overview
The AS7C31026B-10JIN is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a supply voltage range of 3 V to 3.6 V and features a maximum access time of 10 ns. The device utilizes a parallel interface and is housed in a 44-pin Small Outline J-Lead (SOJ) package. It supports surface-mount installation and is rated for commercial operating temperatures ranging from 0°C to +70°C.
Feature Summary
- Provides high-speed asynchronous data access with a 10 ns cycle time for efficient system integration.
- Operates on a single 3.3 V power supply, ensuring compatibility with standard low-voltage logic families.
- Utilizes a 44-pin SOJ form factor designed for compact surface-mount applications.
Applications
- Embedded systems requiring fast local data storage
- Industrial control units needing reliable volatile memory
- Consumer electronics utilizing 3.3 V logic interfaces
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm pinout and electrical characteristics. Ensure the selected variant matches the required temperature grade and packaging style for your assembly process. Cross-reference the full part number with authorized distributors to confirm current availability and authenticity before finalizing procurement plans.
Selection Notes
Select this component when a 64-bit wide data bus is required for memory organization. The 10 ns speed class suits applications demanding rapid read cycles within a 3.3 V environment. Consider the SOJ package dimensions for PCB layout constraints compared to TSOP or BGA alternatives.
Part Context
This part belongs to the AS7C31026B series of 1 Mbit SRAMs. It shares architectural similarities with other members of the family but differs in access speed, voltage tolerance, and physical package configuration. The 'J' suffix typically denotes the SOJ package type used in this specific model.
Replacement Considerations
Direct substitutes include the AS7C31026B-10JCN which offers identical specifications in a tube package. Other variants within the AS7C31026B series may serve as functional replacements if package differences are accommodated in the design.
