silicon-mobilityOLEA T222 is a new member of the OLEA family, the 1st ever automotive micro-controllers with embedded, robust and secured programmable logic. OLEA T222 has been designed to get the best of all the electric machines in the heart of Hybrid Electric Vehicles (HEV) and Electric Vehicles (EV). OLEA T222 flexibility, hard-real time parallel processing and safe architecture makes it a perfect fit to control all flavors of hybridization, micro, mild or full, including Integrated Belt Starter Generator (i-BSG), Crankshaft Motor driven Generator (CMG), Gearbox Motor driven Generator (GMG), in wheel Motor or in axle Motor, DC/DC converter, as well as full Electric power trains.

Furthermore, OLEA T222 technologies and feature set address other applications and make it the ideal controller for Battery Management System (BMS), Exhaust or Selective Catalytic Reduction systems (SCR), or even conventional Internal Combustion Engine. Applications such Damping Control for Chassis will also get the full benefits of OLEA T222.

Car electrification for all

OLEA T222 directly contributes to vehicles CO2 emission reductions by enabling the democratization of cars electrification. Its unique technologies and capabilities allow the downsizing of the electric motors while restituting the best energy efficiency without compromising the vehicle performances. Using OLEA T222, Automotive Tiers1 and OEMs will not only design the most powerful system, but they will also increase drastically the quality of the Electronic Control Unit (ECU), reducing its footprint by limiting the number of components needed to build the application.

Highly integrated and flexible

OLEA T222 features AMEC and SILant, Silicon Mobility’s patented technologies.
AMEC technology is an advanced hard real-time, determinist and parallel interface which combines an embedded programmable logic area (AMEC FLU), designed for automotive constraints, and a specialized actuator/sensor peripherals unit (AMEC PrP). AMEC FLU offers the optimal resources to host the most stringent control algorithms with fast, accurate, parallel and determinist execution. The specialized peripherals unit includes several Pulse Width Modulators (PWM), Complex Wave Generators (CWG), electric motor and engine position predictors, SENTs, PSI5s, SPIs, UARTs and ADC Group managers with integrated analog comparators. As an example AMEC can perform a very high frequency control loop (over 200 KHz) with a high accuracy while ensuring the highest safety integrity level with response time to any system failure in the range of 100 nanoseconds.

SILant technology is a superset of safety features spread across OLEA T222 that ensures the highest system integrity at hardware, software and system level. SILant incorporates high coverage hardware safety mechanisms achieving ASIL-D ISO 26262 compliancy with no compromise on performance.
