Mainly With ST New ASIL-D MCU SPC58NN84, and highly integrated U-chip L9788, Gelu Has Develop a Reference solution of PDCU , that can meet the main requirement of Domain Software and Hardware requirement. The solution includes Key P/N :

 

SPC58NN84 has 200Mhz e200z4 triple-core and 2 lockstep core and Floating Point Unit; 6Mbyte RWW Flash and Max 608Kbyte RAM；High-End Version Of Generic Timer Module(GTM V3) ; Sufficient connectivity resources include 8x CAN FD Support and 100M-Based Ethernet Support; Also 84 channel ADC include 7 SAR ADC module and 6 Sigma-Delta ADC Module; Support Evita-Medium Security Level and ASIL-D Safety Level;

L9788 has integrated 1 pre bost regulator and 1 pre buck regulator;1 linear 5V regulator with 1A output current to support MCU PowerSupply; 3 dependent self-protection 5V tracking regulator with 150ma output; 20+different kinds of HSD/LSD ;Q&A Watchdog; CAN -FD with wakeup function; ASIL-D Safety Level;

L9960T is an automotive H-bridge with full diagnostic support; Operating battery support voltage from 4.5V-28V; Flexible driving strategy via configurable pins PWM/DIR(IN1/IN2);SPI Interface for configuration and diagnosis; Open Load diagnosis in ON condition; Available in single(L9960) and Twin(L9960T)option , same package.

L9305 is a 4 channel driver with integrated Current Sense Path; Redundant Safe Enable Path; Advanced Diagnosis and monitoring;

TJA1101 is a 100BASE-T1 compliant Ethernet PHY optimized for automotive use. With MII and RMII interface to SPC58 eth MAC, 

TJA1145/ATA6570 is High-Speed CAN Transceiver for partial networking; with SPI-interface to configuration / diagnosis and wake detected; Fully meet autosar/OSEK CAN Network management protocol; also suitable for 12V and 24V system;
