STMicroelectronics SPC58NHADPT176S

Overview

SPC58NHADPT176S from STMicroelectronics is a socketed mini evaluation module for the SPC58 H-line 32-bit automotive microcontrollers in LQFP-176 package, featuring on-board 1 GB Ethernet, 8 GB eMMC Flash, dual CAN-FD, dual FlexRay, LINFlexD, and RS232/SCI interfaces - designed for full-signal-access evaluation of automotive powertrain and chassis control systems.

For engineers reviewing the SPC58NHADPT176S datasheet, SPC58NHADPT176S pinout, SPC58NHADPT176S application, or SPC58NHADPT176S equivalent, this board supports standalone 5.0 V operation with integrated 1.25 V/3.3 V regulators, flexible clocking (40 MHz crystal, 8 MHz oscillator, or external SMA input), and modular integration with SPC58XXMB motherboard for complete system-level validation.

Technical Context

The SPC58NHADPT176S implements a daughter-card architecture that exposes all MCU I/O signals via port-ordered 0.1" headers and two 240-way high-density expansion connectors, enabling direct probing and signal injection without soldering. It provides dedicated physical layer interfaces including two DB9-mounted CAN-FD transceivers, dual FlexRay channels with DB9 and alternative connectors, and LINFlexD with dual-style connectors.

Power delivery is segmented across four regulators: switching 5.0 V, 3.3 V, and 1.25 V rails for core/peripheral logic, plus a low-noise linear 5 V regulator reserved exclusively for ADC reference and analog supply domains - ensuring signal integrity during mixed-signal automotive testing.

FAQ

Is the MCU included with the SPC58NHADPT176S board?

No, the SPC58NHADPT176S is a socketed daughter card - the target SPC58 H-line MCU in LQFP-176 package must be purchased separately. The board provides open-top socket access and full signal routing but does not ship with any processor installed.

Can the SPC58NHADPT176S operate independently without the SPC58XXMB motherboard?

Yes, it functions as a standalone unit with its own 5.0 V supply, onboard regulators, Ethernet, eMMC, and peripheral interfaces. The motherboard is optional and used only when expanded I/O, additional peripherals, or multi-card scalability are required.

What clock sources does the board support for MCU operation?

The board supports three clock configurations: a 40 MHz crystal-based oscillator circuit, an 8 MHz onboard oscillator, and an external clock signal fed through the SMA connector - allowing precise timing alignment with vehicle network synchronization requirements.

Does the board include CAN-FD transceivers?

Yes, the SPC58NHADPT176S integrates two high-speed CAN-FD transceivers, each connected to a standard female DB9 connector, enabling direct connection to automotive CAN-FD networks without external level-shifting components.
