SPC56A-Discovery+ Evaluation board
Introduction
The SPC56A-Discovery+ Evaluation board, here after named SPC56A-DISP, helps you evaluate the SPC56 A line Power
®
Architecture
Microcontrollers.
The discovery board is based on SPC564A70L7, a 32-bit Power Architecture Book E compliant e200z335 CPU core with 1.5
Mbyte on-chip in an LQFP176 package.
The numerous interfaces including CAN/SCI/K-LINE/DSPI/GPIO make the SPC564A-DISP an excellent starter kit for customer
quick evaluation and project development.
The SPC56 A line is designed to address cost sensitive powertrain and transmission applications.
The SPC56 A line key functionality is a Time Processing Unit (eTPU) with a coprocessor to create events in sync with internal or
external signals without flooding the CPU with interrupt to serve.
Free ready-to-run application firmware examples are available inside SPC5Studio at
www.st.com
to support quick evaluation
and development.
UM1700 - Rev 3 - July 2021
