Overview
The AS7C1024C-12JIN is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 12 ns. The device utilizes a parallel interface and is housed in a 32-pin Small Outline J-Lead package. It supports single data rate storage and functions reliably across an industrial temperature range from -40°C to +85°C, with a maximum power consumption of 100 mA.
Feature Summary
- Asynchronous operation with fast 12 ns access times for efficient data retrieval
- Industrial-grade thermal stability supporting wide ambient temperature ranges
- Single data rate architecture optimized for standard parallel bus interfaces
Applications
- Industrial control systems requiring reliable non-volatile-like temporary storage
- Embedded applications utilizing 5V logic families
- Data buffering in high-speed parallel communication protocols
Procurement Notes
Verify the specific suffix 'C' against official manufacturer documentation to confirm die revision and electrical characteristics. Ensure the SOJ-32 package dimensions match the target PCB footprint. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Validate that the 12 ns speed grade meets system timing requirements before integration.
Selection Notes
Select this component when a 5V supply is mandatory and industrial temperature ratings are required. Compare against the AS7C1024B series for potential cost or availability differences while maintaining identical pinouts. Consider the AS7C31024 series if lower voltage operation is acceptable. Verify humidity sensitivity levels for proper storage and handling procedures during assembly.
Part Context
This part belongs to the AS7C1024 family of 1 Mbit SRAMs from Alliance Memory. It shares architectural similarities with the AS7C1024B and AS7C1024D variants but differs in specific electrical parameters and manufacturing revisions indicated by the suffix. The SOJ-32 package provides a surface-mount solution suitable for compact industrial electronics designs.
Replacement Considerations
AS7C1024B-12JIN offers similar specifications with potentially different commercial temperature ranges. AS7C1024D-12JIN provides industrial temperature ratings with corner power characteristics. Verify pin compatibility and electrical tolerances before substituting.
