AS7C31024B-10TJCN

Overview

The AS7C31024B-10TJCN is a 1 Mbit (128K x 8) 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 10 ns. The device draws a maximum supply current of 70 mA. It is housed in a 32-pin Small Outline J-Lead (SOJ) package designed for surface mount technology. The component supports commercial operating temperatures ranging from 0°C to +70°C.

Feature Summary

• Provides high-speed asynchronous data access with a 10 ns cycle time.
• Operates on a single 3.3 V power supply within specified voltage limits.
• Utilizes a compact 32-pin SOJ surface-mount package for board integration.

Applications

• Embedded systems requiring fast local data storage
• Industrial control units
• Consumer electronics devices

Procurement Notes

Verify the specific suffix TJCN confirms the 32-pin SOJ package and tube packaging format. Ensure the design accommodates the 3.3 V logic levels and 70 mA current draw. Confirm RoHS compliance status matches project requirements. Validate that the commercial temperature range meets environmental specifications.

Selection Notes

Select this component when a 128K x 8 organization is required with 10 ns speed. Compare against other SRAM families if lower power or different voltage levels are needed. Consider the SOJ footprint constraints during PCB layout. Verify compatibility with existing system bus architectures.

Part Context

This part belongs to the AS7C31024B series of 1 Mbit SRAMs. It shares architectural similarities with other members of the family but differs in pin count and package style. The B-series designation indicates specific electrical characteristics distinct from earlier generations.

Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer's portfolio. Verify that alternative parts maintain the 10 ns access time and 3.3 V operation. Ensure physical dimensions match the existing SOJ-32 footprint.
