STMicroelectronics SPC56EL70L5DISP

Overview

SPC56EL70L5DISP from STMicroelectronics is a Discovery+ evaluation board built around the SPC56EL70L5 32-bit Power Architecture® microcontroller, targeting automotive and industrial safety-critical development. It provides full access to CPU signals, dual CAN/FlexRay interfaces, K-Line, two LIN channels, JTAG debugging, and on-board 5 V/3.3 V regulation from a single 12 VDC input.

For engineers reviewing the SPC56EL70L5DISP datasheet, SPC56EL70L5DISP pinout, SPC56EL70L5DISP application, or SPC56EL70L5DISP equivalent, this board enables rapid validation of ASIL-D–capable communication stacks, real-time control firmware, and functional safety startup sequences using preloaded demos and SPC5Studio's visual code generation engine.

Technical Context

The board implements the SPC56EL70L5 MCU in a 176-pin LQFP package with integrated e200z4d core, 4 MB Flash, 512 KB SRAM, and hardware safety mechanisms including lockstep cores and memory BIST. It supports concurrent operation of two FlexRay channels (with DB9 connectors and jumper enable) and two CAN FD–capable controllers (also DB9-connected).

Hardware resources include a 40 MHz crystal for system clocking, dual potentiometers for analog input simulation, three user LEDs, reset button, and a 37×4 100-mil pin grid array exposing all MCU I/Os-enabling custom carrier board integration without signal multiplexing or routing constraints.

FAQ

Does the SPC56EL70L5DISP include preloaded firmware?

Yes. The board ships with demonstration firmware preloaded in the SPC56EL70L5's Flash memory, enabling immediate stand-alone operation to verify CAN, FlexRay, and LIN functionality without host PC or IDE setup. Firmware source and updates are available at www.st.com/SPC56Ldiscovery.

What development tools are required to use this board?

SPC5Studio is the official IDE-freely downloadable from st.com-and includes the Hightec GNU C compiler (30-day full trial license), BSP, startup code, interrupt handlers, and optional free RTOS. SPC5-UDESTK is recommended for JTAG debugging but not mandatory for basic evaluation.

Can the SPC56EL70L5DISP support ASIL-D development workflows?

Yes. The underlying SPC56EL70L5 MCU integrates hardware safety features including dual lockstep cores, ECC-protected memories, and BIST engines-validated per ISO 26262. The board exposes all relevant safety monitoring pins and allows direct connection to external fault injection and diagnostic test equipment.

Is the 40 MHz crystal on board configurable for other clock frequencies?

No. The 40 MHz crystal is fixed-frequency and serves as the primary reference for the MCU's PLL-based clock generation system. Frequency scaling is achieved entirely in software via PLL configuration registers-not by replacing or adjusting the crystal. Board-level clock tree is non-modifiable.
