AS7C1026B-20JCN

Overview

The AS7C1026B-20JCN is a 1 Mbit (64K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a maximum access time of 20 ns and supports a parallel interface. The device functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum power consumption of 80 mA. It is housed in a 44-pin TSOP-II package suitable for surface-mount technology. The component is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Provides high-speed asynchronous data access with a 20 ns cycle time for efficient system integration.
• Supports standard 5V logic levels compatible with a wide range of microprocessor architectures.
• Designed for industrial environments with extended temperature stability and low power consumption.

Applications

• Industrial control systems requiring reliable non-volatile-like storage capabilities
• Embedded applications utilizing 5V microprocessors and microcontrollers
• Automotive electronics operating under harsh environmental conditions

Procurement Notes

Verify the specific suffix JCN corresponds to the 44-pin TSOP-II package and industrial temperature grade (-40°C to +85°C). Confirm that the 20 ns speed bin meets the timing requirements of the target bus architecture. Ensure compatibility with 5V logic levels before finalizing procurement specifications.

Selection Notes

Select this component when a 1 Mbit capacity with 16-bit word width is required for 5V systems. The industrial temperature range makes it suitable for demanding environments where commercial grade parts may fail. Compare against other AS7C1026B variants if different packaging or speed grades are needed for cost optimization.

Part Context

This part belongs to the AS7C1026B series of 1 Mbit SRAMs from Alliance Memory. It shares architectural similarities with other members of the family but differs in package type and speed grade. The JCN suffix specifically denotes the TSOP-II form factor and industrial rating, distinguishing it from commercial or alternative package versions.

Replacement Considerations

Direct substitutes include other AS7C1026B variants with matching 20 ns speed and 5V operation. Verify pinout compatibility when replacing with similar 44-pin TSOP-II SRAMs from other manufacturers to ensure seamless integration without PCB redesign.
