Microchip Technology Inc. has released 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 well-suited 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.
Microchip’s full suite of development tools support the PIC16F MCUs, including the PICkit™ Low Pin Count Demo Board (part # DM164130-9, $25.99), PICDEM™ Lab Development Kit with PICkit™ 3 (part # DM163045, $134.99), PICDEM Mechatronics (part # DM163029, $149.99),PICkit 3 Starter Kit (part # DV164130, $59.99), MPLAB® ICD 3 Evaluation Kit (part # DV164036, $229.99) and the MPLAB XC8 Compiler for 8-bit PIC MCUs.
