Overview
The AS7C1024B-12TCN is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a 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 32-pin TSOP 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 supply current of 100 mA.
Feature Summary
- Asynchronous operation with a 12 ns maximum access time
- Parallel interface supporting 128K x 8 bit organization
- Surface-mount TSOP-32 package design
Applications
- General-purpose data storage in embedded systems
- Cache memory applications in microcontroller-based designs
- Buffering in industrial control equipment
Procurement Notes
Verify the specific suffix TCN to confirm the TSOP-32 surface-mount package and commercial temperature rating. Ensure the system provides a stable 5V power supply within the 4.5V to 5.5V operating range. Confirm that the design accommodates the required 100 mA maximum current consumption during active read/write cycles.
Selection Notes
Select this component when a 1 Mbit capacity with 12 ns speed is required in a compact surface-mount form factor. It serves as a direct replacement for other 12ns 5V SRAMs in the same package. Consider the 100 mA current draw for power budget calculations. Verify compatibility with existing PCB footprints for the 32-pin TSOP configuration.
Part Context
This part belongs to the AS7C1024B series of 1 Mbit asynchronous SRAMs. It shares architectural similarities with other variants in the family but differs in packaging and temperature specifications. The TCN suffix specifically denotes the TSOP-32 package suitable for automated surface-mount assembly processes.
Replacement Considerations
Check datasheets for pin-compatible alternatives such as the AS7C1024B-12JCN or AS7C1024B-12TJIN. Verify that substitute parts match the 5V logic levels and 12 ns timing requirements. Ensure the replacement package matches the existing board layout constraints.
