Silicon Mobility Announces OLEA T222 for Hybrid and Electric Powertrain Control

VALBONNE, France --- Silicon Mobility introduces OLEA T222, its new breakthrough solution dedicated for hybrid and electric powertrain control. OLEA® T222 is a new member of the OLEA® family, the 1st ever automotive microcontrollers 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 powertrains.

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. SILant® reduces drastically the amount and complexity of Software needed to guarantee the highest level of integrity to the application.

SILant® provides to Safety architects and Software designers predictability, control and precision that Automotive OEM and Tiers1 will translate directly into value in term of savings, time to market, system performances and quality.

Open, standard and simple

OLEA® T222 is based on a standard ARM® Cortex-R5F CPU running at 200Mhz. The device features all the required memories and communications ports: 2 MBytes of Flash, 80 KBytes of system memory; 32 channels ADC with 2 MSamples/sec, LIN and CAN-FD.

OLEA® T222 is ISO 26262 ASIL-D compliant and comes with SEooC (Safety Element out of Context) safety work products to enable customer safety design assessments. The product is AEC-Q100 Grade 1 qualified for operation between -40°C to 125°C ambient temperatures.

OLEA® T222 is the first ARM® based powertrain solution. It comes enriched with the largest ecosystem of software partners and tools providers. OLEA® development flow integrates Model-Based design, automatic code generation, and software/hardware compiler/debugger. A starter kit will soon be announced to complete the offer with AUTOSAR 4.2 compliant software and a development board (OLEA® T222 Application Board).

OLEA® T222 is demonstrable today. Engineering samples will be available to customers during the first quarter of 2017. More information on OLEA® family, OLEA® T222, and OLEA® development environment can be found on Silicon Mobility's website.
