Overview
The AS7C1024C-12TJIN is a 1-Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a single 5V power supply and features a maximum access time of 12ns. The component utilizes a parallel interface for data transfer and is housed in a 32-pin Small Outline J-Lead package. Designed for industrial temperature ranges, it supports standard SMD/SMT mounting techniques.
Feature Summary
- Provides non-volatile-free high-speed data storage via asynchronous parallel interface
- Operates on a single 5V power supply rail
- Engineered for reliable performance within industrial temperature environments
Applications
- Industrial control systems requiring robust memory solutions
- Embedded applications utilizing 5V logic levels
- Data buffering in consumer electronics hardware
Procurement Notes
Verify the specific suffix TJIN to confirm the 32-pin SOJ package and industrial temperature rating. Ensure the design accommodates the 5V operating voltage and 12ns access speed requirements. Confirm availability status as distribution channels may vary. Check for RoHS compliance documentation if environmental regulations apply to the target assembly process.
Selection Notes
Select this component when a 128K x 8 organization is required with 5V compatibility. The 12ns speed suits moderate-frequency asynchronous designs. Consider the SOJ-32 footprint constraints during PCB layout. Compare against commercial variants if industrial temperature range is not necessary for the specific application environment.
Part Context
This part belongs to the AS7C1024 series of 1-Mbit SRAMs from Alliance Memory. It shares architectural similarities with other members like the AS7C1024B but differs in manufacturing die revisions and specific packaging options. The C-series designation typically indicates updated process technology or minor electrical characteristic refinements compared to earlier B-series generations.
Replacement Considerations
Direct substitutes include the AS7C1024B-12TJIN, which shares identical pinout and electrical specifications. Verify that any replacement maintains the same industrial temperature grade and 5V operation. Cross-reference datasheets to ensure functional equivalence before integration.
