Microchip brings integrated op amps to low-cost 8-bit PIC microcontrollers

Microchip has launched two new 8-bit PIC microcontrollers, the PIC16F527 and PIC16F570. The devices combine the ease-of-use of a PIC MCU with low-cost analogue peripherals to create an integrated, cost-effective family that is suitable for a wide range of applications. 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.

Both 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 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 MCU is offered in 20-pin PDIP, SOIC, SSOP and QFN packages and is available today for sampling and volume production. The PIC16F570 is offered in 28-pin PDIP, SOIC, SSOP and QFN packages and is expected to be available in June for sampling and volume production.
