Document Number: MC33910  
Rev. 9.0, 7/2016  
NXP Semiconductors  
Technical Data  
LIN system basis chip with  
high-side drivers  
33910  
The 33910G5/BAC is a SMARTMOS Serial Peripheral Interface (SPI) controlled  
System Basis Chip (SBC), combining many frequently used functions in an MCU  
based system, plus a Local Interconnect Network (LIN) transceiver. The 33910  
has a 5.0 V, 50 mA/60 mA low dropout regulator with full protection and reporting  
features. The device provides full SPI readable diagnostics and a selectable  
timing watchdog for detecting errant operation. The LIN Protocol Specification  
2.0 and 2.1 compliant LIN transceiver has waveshaping circuitry which can be  
disabled for higher data rates.  
SYSTEM BASIS CHIP WITH LIN  
2ND GENERATION  
Two 50 mA/60 mA high-side switches with optional pulse-width modulated  
(PWM) are implemented to drive small loads. One high voltage input is available  
for use in contact monitoring, or as external wake-up input. This input can be  
used as high voltage Analog Input. The voltage on this pin is divided by a  
selectable ratio and available via an analog multiplexer.  
The 33910 has three main operating modes: Normal (all functions available),  
Sleep (VDD off, wake-up via LIN, wake-up inputs (L1), cyclic sense and forced  
wake-up), and Stop (VDD on with limited current capability, wake-up via CS, LIN  
bus, wake-up inputs, cyclic sense, forced wake-up and external reset).  
AC SUFFIX (Pb-FREE)  
98ASH70029A  
The 33910 is compatible with LIN Protocol Specification 2.0, 2.1, and  
SAEJ2602-2.  
32-PIN LQFP
