Combining the SPC56M-Discovery board and EVAL-L9177A evaluation board with related Graphical User Interface (GUI) STSW-L9177A, you can easily evaluate your Small EMS for 2- and 3-wheeled road vehicles (up to 2 cylinders). These solutions can also be used for non-road equipment such as power generators, lawn mowers and snow blowers.
- AEC-qualified integrated components
- Enable compliance with regulations for reduced exhaust emissions and fuel consumption in small combustion engines for 2- and 3-wheeled vehicles which will be mandatory from 2020 onward (Euro5 equivalent and later including OBDII capability)
Dedicated chipset for optimized ECU form factor and cost
To meet the challenge of offering the required ECU/chipset performance at a competitive price enabling its deployment in large quantities, ST offers a high-integration chipset for an optimized ECU form factor and cost.
The backbone of our proposal is the SPC572L64 32-bit Power Architecture MCU and the L9177A peripherals on chip.
Specifically designed for small EFI engine management systems, the SPC572L64 includes specific modules such as the GTM (Generic Timer Module) used to lock and track the angular position of the crankshaft and the decimation filter for managing knock sensor signals to ensure accurate injection and ignition timings with a direct effect on engine emission and consumption performance.
The L9177A contains all the building blocks for EFI systems from key sensor interfaces and load actuations (solenoids, relays, bulbs, etc.) for diagnostics and networking capabilities.
