Overview
The AS7C31026B-20JCNTR is a 1 Mbit (64K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 20 ns. The device utilizes a parallel interface and is housed in a 44-pin SOJ package designed for surface-mount technology. It supports single data rate operations and functions reliably across a commercial temperature range from 0°C to +70°C, with a maximum power consumption of 65 mA.
Feature Summary
- Asynchronous operation with fast access times for standard parallel interface applications
- Low-voltage 3.3V operation compatible with modern digital systems
- Surface-mount packaging suitable for automated assembly processes
Applications
- Embedded memory storage in consumer electronics
- Cache memory buffers in industrial control systems
- Data buffering in telecommunications equipment
Procurement Notes
Verify the specific suffix JCNTR against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure the component meets RoHS compliance requirements for your region. Confirm that the 3.3V operating voltage aligns with your system's power rails before integration.
Selection Notes
Select this component when a 64K x 16 organization is required with 20 ns speed at 3.3V. Compare against the AS7C31026B-15 series if faster access is needed, or the AS7C1026B series if 5V compatibility is necessary. Verify pinout compatibility with existing PCB layouts.
Part Context
This part belongs to the AS7C31026B family of high-speed SRAMs. It shares architectural similarities with other members like the AS7C31026B-15 but differs in speed grade and voltage tolerance. The family is designed for general-purpose memory applications requiring non-volatile-like retention without refresh cycles.
Replacement Considerations
Check for direct substitutes such as the AS7C31026B-15JCNTR for faster performance or AS7C1026B variants for 5V logic levels. Verify pin-to-pin compatibility and electrical characteristics before substitution.
