Overview
The AS7C1024C-12TJINTR is a 1 Mbit asynchronous static random-access memory (SRAM) manufactured by Alliance Memory, Inc. It features a memory organization of 128K x 8 bits and offers a maximum access time of 12 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum power supply current of 160 mA. Designed for industrial applications, it supports an operating temperature range from -40°C to +85°C. The component is housed in a 32-pin Small Outline J-Lead (SOJ) package suitable for surface-mount technology.
Feature Summary
- Asynchronous parallel interface for standard data transfer operations
- Industrial-grade temperature rating for reliable performance in harsh environments
- Surface-mount SOJ-32 package design for compact integration
Applications
- Industrial control systems requiring volatile data storage
- Embedded systems utilizing 5V logic interfaces
- Automotive electronics operating within specified thermal ranges
Procurement Notes
Verify the specific suffix 'IN' against official datasheets to confirm lead-free compliance and RoHS status, as packaging variations may exist. Confirm the SOJ-32 package type matches your PCB footprint requirements. Check for end-of-life notifications or discontinuation notices from Alliance Memory, as availability may be limited. Ensure voltage levels align with system specifications before procurement.
Selection Notes
Select this component when a 128K x 8 configuration is required with 12 ns speed at 5V operation. Consider the SOJ-32 package constraints for board layout. Compare against the AS7C1024B series if different organizational variants are needed. Verify humidity sensitivity class if reflow soldering processes are utilized in manufacturing.
Part Context
This part belongs to the AS7C1024C family of high-speed SRAMs. It shares architectural similarities with the AS7C1024B but may feature updated manufacturing processes. The 'TR' suffix indicates tape and reel packaging, distinct from tube-packaged equivalents like the AS7C1024C-12JIN.
Replacement Considerations
The AS7C1024C-12JIN is a pin-compatible alternative in tube packaging. The AS7C1025B-12TJCNTR offers similar specs but differs in maximum current consumption.
