Debuting as the youngest member of the MAXQ RISC MCU family, the MAXQ7667 SoC, mixed-signal MCU targets cost-sensitive ultrasonic sensor applications in automotive designs that measure weak signals over long distances or identify multiple targets. Measuring 7 mm x 7 mm, the device integrates all functional blocks required to accurately measure position and perform burst control (pulse transmission), analog echo reception, and digital signal processing. It features a programmable burst-frequency generator, programmable burst and duty cycles, an echo receive path that includes a variable gain amplifier, 16-bit sigma-delta ADC, digital bandpass filter, and a digital demodulator with low-pass filtering, and echo detection supported by an interrupt-generating, 16-bit threshold detector with programmable threshold and hysteresis levels. Additionally, the 16-bit, 16-MIPS MCU supports 32 KB of flash, 4 KB of RAM, and 8 KB of ROM. Available in a 48-pin LQFP package with an operating temperature range from -40?C to +125?C, prices start at $8 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
