AS7C4096A-12TCNTR

Memory IC Overview

The AS7C4096A-12TCNTR is a 4 Mbit (512K x 8) asynchronous Static Random Access Memory (SRAM) manufactured by Alliance Memory. It operates with a maximum access time of 12 ns and requires a supply voltage between 4.5 V and 5.5 V. The device features a maximum power consumption of 100 mA and supports parallel interface communication. It is housed in a 44-pin TSOP II package designed for surface mount technology. The component is rated for commercial temperature ranges, typically spanning from 0°C to +70°C, and is supplied in tape and reel packaging.

Memory IC Feature Summary

• Asynchronous operation providing fixed access cycles without clock synchronization
• CMOS technology ensuring low power consumption during active and standby modes
• Parallel interface architecture supporting standard memory control signals
• TSOP II surface mount package optimized for high-density board layouts

Memory IC Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable volatile memory
• Consumer electronics utilizing 5V logic interfaces
• Automotive infotainment subsystems within commercial temperature limits

Memory IC Procurement Notes

Verify the specific suffix TCNTR corresponds to the tape and reel packaging format and commercial temperature grade. Confirm that the 5V operating voltage aligns with your system's power rails. Ensure the 44-pin TSOP II footprint matches your PCB design constraints. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Memory IC Selection Notes

Select this component when a 512K x 8 organization is required with 12 ns speed performance. It is suitable for designs using 5V logic families rather than 3.3V systems. Consider the TSOP II package size relative to available board space. Evaluate thermal management requirements based on the 100 mA maximum current draw in commercial environments.

Memory IC Part Context

This part belongs to the AS7C4096A family of 4 Mbit SRAM devices. Variants exist with different access times such as 15 ns or 20 ns, and other packages like SOJ or TQFP. The -12 designation indicates the 12 nanosecond access speed tier. The TR suffix specifically denotes the tape and reel shipping configuration used for automated assembly processes.

Memory IC Replacement Considerations

Compatible substitutes include AS7C4096A-12TCN for tube packaging or AS7C4096A-12TIN for industrial temperature grades. Verify pin compatibility and voltage levels before substitution. Alternative manufacturers may offer functionally equivalent parts but require electrical parameter validation.
