AS7C1026B-20JCNTR

Overview

The AS7C1026B-20JCNTR is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates on a single 3.3 V power supply with a maximum voltage of 3.6 V and a minimum of 3.0 V. The device features a 20 ns access time and a maximum supply current of 65 mA. It utilizes a parallel interface and is housed in a 44-pin SOJ package designed for surface mount technology. The component supports standard dynamic random-access memory operations within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Provides high-speed asynchronous data access with a 20 ns cycle time for efficient system integration.
• Operates on a low-voltage 3.3 V power supply, reducing overall system power consumption.
• Features a compact 44-pin small outline J-leaded package suitable for space-constrained surface-mount designs.

Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable volatile memory
• Consumer electronics utilizing 3.3 V logic levels

Procurement Notes

Verify the specific suffix JCNTR against the manufacturer's official datasheet to confirm the exact package variant and tape-and-reel configuration. Ensure that the 3.3 V operating voltage aligns with your system's power rails. Confirm RoHS compliance status through the latest product documentation before finalizing procurement orders.

Selection Notes

Select this component when a 64-bit wide memory interface is required at 3.3 V. Compare against the AS7C1026B series for alternative access times or voltage options. Ensure the 44-pin SOJ footprint matches your PCB layout constraints. Verify thermal requirements against the commercial temperature range specifications.
