Integrated op amps added to low-cost 8-bit PIC MCUs
With an on-chip dual Op Amp module, 8-bit ADC and two comparators, these MCUs are suitable for systems that require signal conditioning and amplification to interpret analogue 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 programme Flash memory, which allows for high-use data EEPROM functionality. These key features, in addition to the integration of commonly used analogue peripherals, make the PIC16F527 and PIC16F570 well suited to a number of low-cost sensor products, such as smoke detectors, carbon-monoxide detectors, photo sensors and automotive sensor-interface modules.
The PIC16F527 occupies 20-pin PDIP, SOIC, SSOP and QFN; the PIC16F570 in 28-pin PDIP, SOIC, SSOP and QFN packages. Microchip’s full suite of development tools supports the PIC16F MCUs, including the PICkit Low Pin Count Demo Board (DM164130-9) priced at $25.99; PICDEM Lab Development Kit with PICkit 3 (DM163045) at $134.99; PICDEM Mechatronics (DM163029) at $149.99; PICkit 3 Starter Kit (DV164130) at $59.99; MPLAB ICD 3 Evaluation Kit (DV164036) at $229.99; and the MPLAB XC8 Compiler for 8-bit PIC MCUs.
