AS6C62256-55STINTR

Memory IC Overview

The AS6C62256-55STINTR is a 256 kbit (32K x 8) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory. It features a parallel interface with a maximum access time of 55 ns. The device operates within a supply voltage range of 2.7 V to 5.5 V and has a maximum power supply current of 45 mA. It is housed in a surface-mount sTSOP-28 package with 28 pins. The component supports an extended industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Asynchronous parallel SRAM architecture for direct data access
• Wide supply voltage compatibility supporting 2.7V to 5.5V operation
• Extended industrial temperature rating for reliable performance in harsh environments

Memory IC Applications

• Industrial control systems requiring non-volatile-like temporary storage
• Embedded applications with strict temperature constraints
• Data buffering in communication interfaces

Memory IC Procurement Notes

Verify the specific suffix STI against official datasheets to confirm the sTSOP-28 surface mount package and industrial temperature grade. Ensure the 55 ns speed class matches system timing requirements. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Memory IC Selection Notes

Select this component when a 32K x 8 organization is required with a 55 ns access speed. The wide voltage range allows flexibility in power design. The sTSOP-28 package suits space-constrained PCB layouts. Verify that the 45 mA active current fits the thermal budget.

Memory IC Part Context

This part belongs to the AS6C62256 series of high-speed asynchronous SRAMs. It provides a cost-effective solution for general-purpose memory applications where data retention is not required during power loss. The series offers various speed grades and package options to accommodate different design constraints.

Memory IC Replacement Considerations

Cross-reference with other Alliance Memory parts in the AS6C62256 family, such as AS6C62256-55PCN or AS6C62256A-70SCN, ensuring pinout and electrical specifications match exactly before substitution.
