The -20°C to 70°C temperature grade suits cabin or infotainment domains, not the engine bay — the AEC-Q100 grade 3 or 4 window covers interior ambient conditions with margin.
Housed in a 6-SMD no lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.
The 24 MHz CMOS output directly drives the STM32F4 HSE input — the supply voltage range (2.25 V to 3.6 V) covers the MCU's VDD. Confirm the enable/disable polarity matches your reset scheme; the DSC1121 uses active-low enable per the series datasheet.
