AS7C1026C-15JINTR

Overview

The AS7C1026C-15JINTR is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within 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 parallel interface operations with a maximum power supply current of 210 mA. It is designed for surface-mount installation in a 44-pin SOJ package, specifically configured for tape and reel delivery. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides 1 Mbit storage capacity organized as 64 K words by 16 bits using asynchronous parallel logic.
• Supports high-speed data retrieval with a guaranteed 15 nanosecond access time specification.
• Operates on standard 5V power supplies ranging from 4.5V to 5.5V with defined current limits.

Applications

• Industrial control systems requiring robust memory under varying thermal conditions
• Embedded computing architectures utilizing 16-bit data buses
• Automotive electronics operating within specified industrial temperature ranges

Procurement Notes

Verify the specific suffix JINTR confirms the tape and reel packaging format against official datasheets before ordering. Confirm that the 44-pin SOJ footprint matches the target PCB design constraints. Ensure the 5V logic levels align with the host system's I/O specifications. Check for RoHS compliance documentation if environmental regulations apply to the final assembly process.

Selection Notes

Select this component when a 16-bit wide memory interface is required for 1 Mbit capacity. The 15 ns speed class suits applications needing moderate-to-high throughput without complex synchronization. The industrial temperature rating makes it suitable for harsh environments where commercial grade parts would fail. Verify that the SOJ package style is compatible with available surface-mount assembly equipment.

Part Context

This part belongs to the AS7C1026C series of fast asynchronous SRAMs. It shares architectural similarities with other members like the AS7C1026C-15JIN but differs in packaging configuration. The series targets general-purpose memory needs in embedded systems. All variants maintain consistent electrical characteristics while offering different physical form factors for diverse board layout requirements.

Replacement Considerations

AS7C1026C-15JIN serves as a tube-packaged alternative within the same series. Both share identical electrical parameters and pinouts. Substitution requires verifying that the receiving assembly process supports the specific tape and reel format of the JINTR variant.
