The E524.1x with integrated microcontroller offer ul-
trasonic range detection with minimum component
count. A single ultrasonic transducer with a center
tapped transformer is directly driven with programma-
ble 30kHz to 80kHz bursts. Supported transducers al-
low distance measuring from 15cm to 4m and beyond
in extended range mode.
The received echo signal is amplified and converted
by an ADC. Digital filtering achieves excellent tracking
with the sending frequency without external compo-
nents or trimming. Optional temperature compensa-
tion is available through GPIO pins.
An onboard EEPROM stores processed values of the os-
cillator/sending frequency, transmitted power and re-
ceiver sensitivity. Communication to an ECU is via a sin-
gle-wire bus compatible with LIN 2.1. For ease of use,
a System ROM is pre-programmed with application
support routines. Available software examples cover
threshold-based echo detection, a basic LIN stack and
a complete USPA application example
