LISTED UNDER:

ec911ic234-webPurportedly optimized for automotive-sensor systems such as EPA (electronic parking assist) and PDC (park-distance control), the MAXQ7667 SoC (system-on-chip) mixed-signal microcontroller from Maxim is intended for ultrasonic sensor applications. The echo receive path includes a variable gain amplifier, a 16-bit sigma-delta ADC, a digital bandpass filter to eliminate OOB (out-of-band noise), and a digital demodulator with lowpass filtering. The microcontroller supports 32 KB of flash, 4 KB of data RAM, and 8 KB of utility ROM. The 7 mm by 7 mm device is available in a 48-pin LQFP package. From $8.
