MCUs from Microchip feature on-chip op amps, high-speed comparators, and ADC
Microchip Technology Inc. announced two 8-bit PIC® microcontrollers: the PIC16F527 and PIC16F570, which combine the ease-of-use of a PIC MCU with low-cost analog peripherals to create a well-integrated, cost-effective family suitable for a wide range of applications. With an on-chip dual op-amp module, 8-bit ADC, and two comparators, these MCUs are ideal for systems that require signal conditioning and amplification to interpret analog inputs.
The PIC16F527 and PIC16F570 employ a small and highly-efficient 8-bit architecture, and add several features to support ease of use and system robustness. The all-new hardware interrupt capability gives designers the freedom to implement more complex functions without adding software overhead, while an integrated Brown-Out Reset (BOR) can detect faults in system power and safely reset the MCU to avoid memory corruption. The two MCUs also feature self-read/write program Flash memory, which allows for high-use data EEPROM functionality. These key features, along with the integration of commonly used analog peripherals, make the PIC16F527 and PIC16F570 well suited for a number of low-cost sensor products, such as smoke detectors, carbon-monoxide detectors, photo sensors, and automotive sensor-interface modules.
