Overview
The AS7C1024B-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 4.5 V to 5.5 V with a maximum current consumption of 100 mA. The device features a 12 ns access time and utilizes a parallel interface. It is housed in a 32-pin SOJ package designed for surface mount technology. The component supports single data rate storage and functions reliably across an operating temperature range from 0°C to +70°C.
Feature Summary
- Provides high-speed asynchronous data access with a 12 ns cycle time for efficient system integration.
- Utilizes CMOS technology to deliver low power consumption suitable for battery-backed applications.
- Features a compact 32-pin SOJ surface-mount package optimized for space-constrained designs.
Applications
- Battery backup nonvolatile memory systems
- Industrial control equipment requiring fast data buffering
- Consumer electronics utilizing 5V logic interfaces
Procurement Notes
Verify the specific suffix TJINTR against official datasheets to confirm tape-and-reel packaging and industrial-grade temperature ratings. Ensure compatibility with 5V logic levels and check for moisture sensitivity handling requirements during assembly. Confirm RoHS compliance status through manufacturer documentation before procurement.
Selection Notes
Select this component when a 128K x 8 organization is required with 5V operation. Compare against the AS7C1024B-12JCN for tube packaging alternatives. Consider the AS7C1024D-12TJINTR if extended industrial temperature ranges are necessary instead of commercial limits.
Part Context
This part belongs to the AS7C1024B series of fast asynchronous SRAMs. It shares architectural similarities with other 1Mbit devices in the lineup but differs in packaging and temperature specifications. The B-series designation indicates standard performance characteristics typical of this generation of CMOS static RAM products.
Replacement Considerations
AS7C1024B-12JCN offers identical electrical specifications in a tube package. AS7C1024D-12TJINTR provides similar functionality with extended temperature capabilities. Verify pinout compatibility before substituting.
