STMicroelectronics SPC58XXADPT176S

Overview

SPC58XXADPT176S from STMicroelectronics is a socketed mini-module daughter card for evaluating SPC58EE84E7, SPC58NE84E7, SPC58EN84E7, SPC58EG84E7, and SPC58NG84E7 automotive microcontrollers in QFP176 package. It provides full access to CPU I/O signals, supports dual CAN-FD, FlexRay, LINFlexD, Ethernet, RS232/SCI, and analog input via potentiometer - designed for functional validation of powertrain and chassis control units.

For engineers reviewing the SPC58XXADPT176S datasheet, SPC58XXADPT176S pinout, SPC58XXADPT176S application, or SPC58XXADPT176S equivalent, key selection considerations include QFP176 socket compatibility, 12 V single-supply operation, on-board 5.0 V / 3.3 V / 1.25 V switching regulators, dual CAN-FD with DB9 connectors, and FlexRay channel support with DB9 and alternative interfaces.

Technical Context

This evaluation board implements a modular architecture where the SPC58XXADPT176S daughter card mates with the SPC58XXMB motherboard to form a complete SPC58 modular evaluation system. It exposes all MCU signals via port-ordered 0.1" pitch headers and integrates four independent voltage regulators - including a dedicated 5 V linear regulator for ADC reference stability.

The board supports flexible clocking: 40 MHz crystal, 8 MHz oscillator, or external clock via SMA connector. It includes two 240-way high-density expansion connectors, JTAG/LFAST LVDS (10-pin), SIPI (10-pin), and standard 14-pin JTAG - enabling debug, trace, and high-speed interface evaluation for automotive-grade MCU development.

FAQ

Is the SPC58XXADPT176S sold with an MCU installed?

No. The SPC58XXADPT176S is a socketed daughter card only - the target MCU (e.g., SPC58EE84E7) must be purchased separately and manually inserted into the open-top QFP176 socket. This allows reuse across multiple MCU variants within the same package footprint.

What motherboard is required to operate this board?

The SPC58XXADPT176S requires the SPC58XXMB motherboard to function as a complete evaluation system. The daughter card plugs into the motherboard's high-density expansion interface and relies on its power distribution, peripheral transceivers, and debug infrastructure.

Does this board support CAN FD and FlexRay simultaneously?

Yes. The board provides two independent high-speed CAN-FD channels (with DB9 connectors) and two FlexRay channels (each with DB9 and alternate connectors), enabling concurrent multi-bus automotive network testing without signal contention or shared resource limitations.

Can the SPC58XXADPT176S be used standalone without the motherboard?

Yes - as a standalone unit when only basic MCU signal access or socket-based programming is needed. However, full peripheral functionality (CAN, FlexRay, Ethernet, etc.) requires connection to the SPC58XXMB motherboard, which hosts the transceivers and physical layer components.
