AS7C1025B-15TJCN

Overview

The AS7C1025B-15TJCN is a 1 Mbit (128K x 8) static random-access memory (SRAM) manufactured by Alliance Memory, Inc. It operates with a maximum access time of 15 ns and supports a parallel interface. The device functions within a supply voltage range of 3.0 V to 3.6 V, with a maximum power consumption of 60 mA. It is housed in a 32-pin Small Outline J-Lead (SOJ) package with a 300 mil footprint. The component is rated for commercial temperature operation, spanning from 0°C to +70°C.

Feature Summary

• Provides high-speed asynchronous data access with a 15 ns cycle time for efficient system performance.
• Features a center power pin configuration to optimize signal integrity and reduce noise in the circuit layout.
• Utilizes a standard 32-pin SOJ package designed for surface-mount technology applications.
• Operates on a single 5V-compatible power supply rail within specified tolerance limits.

Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable volatile memory
• Consumer electronics with space-constrained PCB layouts

Procurement Notes

Verify the specific suffix TJCN against the manufacturer's latest datasheet to confirm the package type and temperature grade. Ensure that the design accommodates the 32-pin SOJ form factor and that the power supply rails strictly adhere to the 3.0 V to 3.6 V operating range to prevent device damage or malfunction during operation.

Selection Notes

Select this component when a 128K x 8 organization is required with a 15 ns speed grade. It is suitable for designs utilizing 5V logic levels but requiring strict voltage regulation between 3.0 V and 3.6 V. Consider the SOJ-32 package constraints and commercial temperature range limitations before finalizing the bill of materials for the target application environment.
