Overview
The AS7C1026B-12TINTR is a 1 Mbit (64K 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 12 ns. The device utilizes a parallel interface and is housed in a 44-pin TSOP II package with surface-mount installation. It supports single data rate (SDR) storage and is rated for industrial operating temperatures ranging from -40°C to +85°C. The component is supplied in tape and reel packaging.
Feature Summary
- Provides 1 Mbit non-volatile-capable data retention via static RAM architecture
- Supports high-speed asynchronous read operations with 12 ns access time
- Designed for industrial temperature environments ensuring stable performance
- Utilizes standard parallel interface for direct microcontroller or processor connection
Applications
- Industrial control systems requiring fast data buffering
- Embedded systems with strict timing constraints
- Automotive electronics operating in harsh thermal conditions
- Communication equipment needing rapid temporary data storage
Procurement Notes
Verify the suffix TINTR confirms tape and reel packaging and industrial temperature grade. Confirm the 44-pin TSOP II footprint matches your PCB design. Check RoHS compliance status on the official datasheet. Ensure voltage requirements align with your system's 5V logic levels. Validate humidity sensitivity handling procedures during assembly.
Selection Notes
Select this part when 64-bit wide data paths are required compared to 8-bit alternatives. Consider the 12 ns speed for applications demanding faster response than slower SRAM variants. Evaluate the TSOP II package size against available board space. Compare power consumption specifications if battery life is critical. Verify compatibility with existing address and data bus widths.
Part Context
This component belongs to the AS7C1026B series of 1 Mbit SRAM devices. It shares architectural similarities with other members like AS7C1026B-12TIN but differs in packaging and temperature rating. The series offers various access times and organizational configurations to suit different embedded memory needs.
Replacement Considerations
AS7C1026B-12TIN is a tube-packaged equivalent with identical electrical characteristics. AS7C1026B-15TINTR offers a slower 15 ns access time in the same package. AS7C1026B-10TIN provides faster 10 ns access in the same form factor.
