Overview
The AS7C164A-15JINTR is a 64 Kbit (8K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 4.5 V to 5.5 V with a maximum supply current of 140 mA. The component features a 15 ns access time and supports parallel interface communication. Designed for industrial applications, it functions between -40°C and +85°C. The device is housed in a 28-pin Small Outline J-Lead (SOJ) package and is supplied in tape and reel format.
Feature Summary
- Provides non-volatile data retention characteristics typical of SRAM technology without requiring refresh cycles.
- Supports standard parallel data bus interfaces for direct microprocessor connectivity.
- Engineered for reliable operation across extended industrial temperature ranges.
Applications
- Industrial control systems requiring robust memory performance under varying environmental conditions.
- Embedded systems utilizing 5V logic families for data buffering and storage.
- Automotive electronics operating within specified industrial temperature limits.
Procurement Notes
Verify the specific suffix JINTR confirms the SOJ-28 package and tape-and-reel delivery method. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with 5V power supplies and 15 ns timing requirements. Check for moisture sensitivity handling instructions due to surface mount construction.
Selection Notes
Select this component when an 8K x 8 organization is required for 5V asynchronous applications. Consider the SOJ-28 footprint constraints against available board space. Evaluate the 140 mA active current consumption against system power budgets. Compare industrial temperature ratings against commercial alternatives if environmental exposure is limited.
Part Context
This part belongs to the AS7C164A series of high-speed SRAMs from Alliance Memory. It serves as a drop-in replacement for legacy 64K-bit memory solutions in 5V systems. The series emphasizes low power consumption and fast access times for embedded computing tasks.
Replacement Considerations
Check datasheets for pin-compatible alternatives such as the AS7C164A-15JIN (tube packaging). Verify electrical specifications match exactly before substituting packages or manufacturers.
