Overview
The AS7C1025B-15JIN is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 15 ns. The device supports single data rate operation and has a maximum power consumption of 90 mA. It is designed for surface mount installation in a 32-pin Small Outline J-Lead package. The component functions within an industrial temperature range from -40°C to +85°C.
Feature Summary
- Asynchronous parallel interface for standard memory control
- Single data rate architecture optimized for general-purpose storage
- Industrial-grade thermal stability across extended temperature ranges
Applications
- Embedded systems requiring non-volatile-like persistence without battery backup
- Industrial control units operating in harsh thermal environments
- Consumer electronics utilizing 5V logic families
- Automotive infotainment and instrumentation modules
Procurement Notes
Verify the specific suffix 'JIN' against official datasheets to confirm the SOJ-32 package and tube packaging format. Ensure the design accommodates the 5V supply requirement, as this variant differs from 3.3V counterparts. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement specifications.
Selection Notes
Select this component when a 5V supply rail is available and a 15 ns access speed meets system timing requirements. Compare against the AS7C1025B-12 series if faster performance is needed, noting potential differences in power consumption. Verify that the 32-pin SOJ footprint fits the PCB layout constraints compared to TSOP or BGA alternatives.
Part Context
This part belongs to the AS7C1025B family of 1 Mbit SRAMs. It shares architectural similarities with other members like the AS7C1026B but differs in organization and pin count. The '15' indicates the speed grade, while 'JIN' specifies the lead type and packaging style unique to this SKU within the broader Alliance Memory portfolio.
Replacement Considerations
The AS7C1025B-12JIN offers faster 12 ns access times within the same package and voltage range. For 3.3V applications, the AS7C31025B series provides equivalent capacity with lower power consumption.
