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 or L9779WD-SPI 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 and L9779WD contain all the building blocks for EFI systems from key sensor interfaces and load actuations (solenoids, relays, bulbs, etc.) for diagnostics and networking capabilities.
Each component has its own set of collaterals and development toolchain; a complete ECU hardware reference design is also available.
