CS8391AT

Overview

The CS8391AT is an ARM-based microcontroller belonging to the PSoC 4 family manufactured by Infineon Technologies. It is classified as an End-of-Life (EOL) product, with official discontinuance notifications available in public documentation. The component utilizes a Tube packaging format and is subject to moisture sensitivity requirements. Distribution availability is currently restricted or unavailable through major distributors like Mouser.

Feature Summary

Based on ARM architecture within the PSoC 4 MCU family
Includes embedded protection features typical of the series

Applications

General-purpose microcontroller applications requiring ARM processing
Legacy system maintenance for existing PSoC 4 designs

Procurement Notes

This component is officially designated as End-of-Life (EOL). Buyers must verify current stock status directly with authorized suppliers, as distribution channels may no longer carry new units. Review the official EOL notification PDF from Infineon for specific discontinuance timelines and last-time-buy dates before initiating procurement actions.

Selection Notes

Due to the EOL status, this part is unsuitable for new design-in projects requiring long-term supply assurance. Engineers should evaluate alternative active microcontrollers within the Infineon portfolio that offer comparable ARM Cortex-M capabilities and updated support lifecycles for future production needs.

Part Context

The CS8391AT belongs to the PSoC 4 family of programmable system-on-chip microcontrollers. This family integrates configurable analog and digital peripherals around an ARM core, allowing for flexible hardware customization. The AT suffix typically denotes specific package or temperature grade variations within the broader product line.
