Overview
The AS7C1026B-15JINTR is a 1 Mbit (64K x 16) asynchronous static random access memory manufactured by Alliance Memory. It operates at a maximum access time of 15 ns with a supply voltage range of 4.5 V to 5.5 V and a maximum power consumption of 210 mA. The component utilizes a parallel interface and is housed in a 44-pin Small Outline J-Lead package. It supports industrial operating temperatures from -40°C to +85°C and is supplied in tape and reel packaging.
Feature Summary
- Provides high-speed asynchronous data access with a 15 ns cycle time for efficient system integration.
- Features a compact 44-pin SOJ surface-mount package designed for space-constrained industrial applications.
- Operates reliably within an extended industrial temperature range of -40°C to +85°C.
Applications
- Industrial control systems requiring robust memory solutions
- Embedded systems operating in harsh environmental conditions
- Data acquisition modules needing fast asynchronous access
Procurement Notes
Verify the specific suffix JINTR confirms the tape and reel packaging format, as standard variants may use tubes. Confirm the 15 ns speed grade matches system timing requirements. Ensure the 44-pin SOJ footprint aligns with the target PCB layout. Validate that the industrial temperature rating meets operational standards. Check current availability status as production cycles may vary.
Selection Notes
Select this part when a 64K x 16 organization is required for 5V logic interfaces. Consider the SOJ package for specific board space constraints compared to TSOP alternatives. Verify that the 210 mA active current draw fits within the system power budget. Ensure compatibility with existing asynchronous SRAM controllers or bus architectures.
Part Context
This component belongs to the AS7C1026B series of 1 Mbit SRAM devices. It shares architectural similarities with other members like the AS7C1026C-15JIN but differs in manufacturing revision and packaging options. The JINTR suffix specifically denotes the industrial temperature range and tape-and-reel delivery method for automated assembly.
Replacement Considerations
The AS7C1026B-15JIN serves as a tube-packaged alternative within the same family. Cross-check pinout compatibility and electrical specifications before substitution. Verify that the replacement variant meets the same industrial temperature and speed requirements.
