The SPC5-L9177A-K02 ECU Reference Design is intended for the small engines used in motorcycles and scooters that have to comply with the upcoming Euro 5, Bharat Stage VI (BSVI), and China IV regulations. The reference design is also appropriate for generators, nautical engines, and agricultural engines that require an EFI ECU.
The reference design is based around ST’s SPC572L Line 32-bit Power Architecture automotive-powertrain MCU and L9177A high-integration IC hosting power supplies, interfaces and load actuators. ST’s STGD18N40 IGBT and L9616 CAN interface IC are also included.
The board comes with a full ecosystem, including SPC5Studio IDE which includes low-level drivers, a Generic Timer Module (GTM) configurator for the SPC572L Line, and powertrain libraries for engine crank position sensor and actuations. Basic application software developed with ST Partner eMoticom helps users start and manage a single-cylinder engine.
