Product details
Overview
MSP432E401YTPDT from Texas Instruments is a 120-MHz Arm® Cortex®-M4F microcontroller with integrated 10/100 Ethernet MAC and PHY, IEEE 1588 PTP hardware support, 1024KB flash, 256KB SRAM, and hardware AES/SHA/DES encryption engines - deployed in industrial Ethernet gateways requiring real-time control, secure connectivity, and deterministic timing.
For engineers reviewing the MSP432E401YTPDT datasheet, MSP432E401YTPDT pinout, MSP432E401YTPDT application, or MSP432E401YTPDT equivalent, key selection criteria include Ethernet PHY integration, dual CAN 2.0A/B controllers, 12-bit dual ADC (2 Msps), tamper detection support, and 128-pin TQFP package compatibility with industrial temperature range (–40°C to 105°C).
Technical Context
The MSP432E401YTPDT implements an Arm Cortex-M4F core with FPU and MPU, executing Thumb-2 instructions at 120 MHz (150 DMIPS), backed by a multi-bus architecture including AHB for high-speed peripherals and APB for system peripherals. Its integrated Ethernet subsystem includes full MAC+PHY with MII interface and IEEE 1588 timestamping logic embedded in hardware.
Peripherals are organized across dedicated buses: eight UARTs with independent clocking, four QSSI modules supporting quad-SSI, ten I²C modules (including high-speed mode), two CAN controllers, and dual 12-bit SAR ADCs each capable of 2 million samples per second - all accessible via configurable GPIO multiplexing and managed by a 32-channel µDMA controller.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32H743VIT6 | No integrated Ethernet PHY; requires external PHY (e.g., LAN8742A); higher core clock (480 MHz) but no IEEE 1588 hardware acceleration. | Better for compute-intensive vision/AI edge tasks; less optimal for deterministic time-synchronized Ethernet where PHY integration reduces latency and layout complexity. | Select when raw processing throughput outweighs Ethernet PHY integration and IEEE 1588 precision. |
| RZ/T2M (R7S92200 | ARM Cortex-R4 dual-core real-time processor; integrated TSN-capable Ethernet switch; larger package (324-pin BGA); no hardware AES/SHA accelerators. | Targeted at multi-protocol TSN time-critical automation (e.g., servo drive coordination); lacks on-chip crypto for secure remote firmware updates. | Select when Time-Sensitive Networking (TSN) switching and ultra-low jitter (<100 ns) are mandatory, and external crypto ICs are acceptable. |
Compared with STM32H743VIT6 and RZ/T2M, the MSP432E401YTPDT uniquely combines integrated 10/100 PHY, IEEE 1588 hardware timestamping, and full-suite crypto accelerators in a 128-pin TQFP - delivering lowest component count and deterministic timing for cost-sensitive industrial gateways.

The MSP432E401YTPDT is rated for an extended ambient temperature range of –40°C to 105°C, validated per JEDEC JESD22-A104. This makes it suitable for deployment in uncontrolled industrial environments such as factory floors, outdoor substations, and HVAC mechanical rooms where thermal management is constrained.
Does the MSP432E401YTPDT include an integrated Ethernet PHY?
Yes, the MSP432E401YTPDT integrates a full 10/100 Ethernet PHY with MII interface and IEEE 1588 Precision Time Protocol (PTP) hardware timestamping logic. No external PHY IC is required - only magnetics and RJ45 connector are needed for functional Ethernet connectivity.
How many UART interfaces does the MSP432E401YTPDT support?
The MSP432E401YTPDT supports eight independent UART modules, each with separately configurable transmitter and receiver clocks. This enables concurrent communication with multiple legacy industrial devices (e.g., Modbus RTU slaves, barcode scanners, HMIs) without software-based bit-banging or multiplexing overhead.
What security features are implemented in hardware on the MSP432E401YTPDT?
The MSP432E401YTPDT includes hardware-accelerated AES-128/192/256, DES, SHA-1/SHA-2/MD5, CRC-16/32, and four configurable tamper detection inputs. These features are accessible via ROM-based drivers and do not consume CPU cycles during cryptographic operations - essential for maintaining real-time performance in secure industrial protocols.
Is the MSP432E401YTPDT pin-compatible with other members of the MSP432E4 family?
Yes, the MSP432E401YTPDT shares identical pinout and package (128-pin TQFP PDT) with other variants in the MSP432E4x series, including MSP432E411Y and MSP432E411Y.
