MSP432E401YTPDT Technical Specifications

MSP432E401YTPDT Key Features

• Single ARM Cortex-M4F core with floating-point unit for faster DSP and control loops.
• On-chip 256 KB Flash and 64 KB SRAM to store larger firmware and buffers compared with smaller MCUs.
• Integrated 10/100 Ethernet MAC enabling direct LAN connectivity without external controllers.
• Built-in USB 2.0 OTG to support host or device modes for flexible peripheral interfacing.

Typical Applications

• Industrial Ethernet gateways and protocol converters that need deterministic packet handling and reliable 100 Mbps MAC throughput for networked equipment.
• Embedded control systems where higher CPU performance and hardware floating point yield tighter motor or process control loops with less jitter.
• IoT edge devices requiring local data aggregation, USB connectivity for maintenance, and sufficient flash/RAM to run secure stacks and logging features.
• Automation controllers and human-machine interfaces that need more memory and peripheral count than typical 8/16-bit MCUs to support advanced firmware and multiple interfaces.

MSP432E401YTPDT Advantages vs Typical Alternatives

Compared with entry-level microcontrollers, this device offers significantly higher clock speed and more on-chip memory, making it better suited for compute-heavy or networking tasks. The inclusion of a hardware floating-point unit and native Ethernet MAC reduces system cost and latency versus alternatives that require external PHYs or coprocessors. Its 100-pin package provides more I/O and peripheral lanes, supporting integration into more complex systems with fewer external components.
