AS7C31025B-12JIN

Overview

The AS7C31025B-12JIN is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 12 ns. The device utilizes a parallel interface and is housed in a 32-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology. It supports single data rate operations and functions within an industrial temperature range from -40°C to +85°C, with a maximum power consumption of 65 mA.

Feature Summary

Provides high-speed asynchronous data access with a 12 ns cycle time for efficient system integration.
Operates on a standard 3.3 V power supply, ensuring compatibility with low-voltage logic systems.
Utilizes a compact 32-pin SOJ surface-mount package to optimize board space utilization.

Applications

Industrial control systems requiring reliable memory storage under varying environmental conditions.
Embedded applications utilizing 3.3 V microcontrollers or processors.
Data acquisition modules needing fast random-access capabilities.

Procurement Notes

Verify the specific suffix 'JIN' corresponds to the industrial temperature grade (-40°C to +85°C) and the 32-pin SOJ package configuration. Confirm that the 3.3 V operating voltage aligns with the target system's power rails. Ensure the 12 ns speed grade meets the timing requirements of the host processor bus. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a 1 Mbit capacity is required in a 128K x 8 organization. Choose this part over the 5 V variant (AS7C1024B series) if the design mandates 3.3 V operation. Consider the SOJ-32 package constraints against available PCB real estate. Verify that the 12 ns access time satisfies the clock speed of the connected controller.

Part Context

This component belongs to the AS7C31025B family of 1 Mbit SRAM devices. It shares architectural similarities with other members like the AS7C31024B but differs in voltage tolerance and temperature rating. The 'JIN' designation specifically identifies the industrial temperature range and leaded package style within the manufacturer's portfolio.
