Overview
The AS7C31025C-12TJINTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 12 ns. The device utilizes a parallel interface and is housed in a 32-pin SOJ package designed for surface-mount technology. It supports single data rate operation and functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Asynchronous parallel interface architecture
- Industrial-grade wide temperature operational capability
- Surface-mount leaded package design
Applications
- Industrial control systems
- Embedded storage applications
- Data buffering in electronic circuits
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability. Confirm RoHS compliance status prior to integration. Check current lifecycle status as the part may be discontinued. Ensure proper handling procedures are followed given moisture sensitivity classification requirements during assembly processes.
Selection Notes
Select this component when 128K x 8 organization and 12 ns speed are required for 3.3V logic systems. Consider the SOJ-32 package constraints for PCB layout. Verify that the -40°C to +85°C operating range meets environmental specifications. Compare power consumption limits against system thermal budgets before finalizing the design choice.
Part Context
This SRAM belongs to the AS7C31025C series, representing a specific generation of 1 Mbit memory solutions. It differs from commercial variants by its extended temperature rating and from other pinouts like TSOP by its physical form factor. The suffix indicates specific packaging and tape-and-reel configuration details defined by the manufacturer.
Replacement Considerations
AS7C31025B-12JCNTR shares similar electrical characteristics but operates at commercial temperatures. AS7C31025C-12TCN offers the same performance in a TSOP package. Verify pin compatibility and voltage levels before substituting.
