PIC MCU families feature core-independent peripherals

July 21, 2015 // By Graham Prophet
Microchip Technology has added an MCU with ADC computation, and the first PIC16 with new low-power modes – PIC16F18877. Also announced is the PIC16F1579, an 8-bit PIC MCU with four independent time-based 16-bit PWMs. Interconnected core-independent peripherals perform functions without the core; serial interfaces for LIN and DMX, and intelligent analogue for signal and sensor interfaces.

Core-Independent Peripherals (CIPs) in 8-bit MCUs can now be used in a much broader range of applications, due to the growing number of these intelligent, interconnected CIPs that combine to perform functions autonomously, without the core. Because these functions are deterministically and reliably performed in hardware instead of software, CIPs enable system performance that is beyond typical 8-bit MCUs while simplifying design and reducing memory cost. These two families are available in 8 to 40-pin packages, reducing board space while operating from 1.8 to 5.5V. Both families offer the Peripheral Pin Select feature, which enables flexible pin mapping and PCB routing to minimise EMI and crosstalk. Example applications include consumer electronics, the Internet of Things (IoT), wearable technology and safety-critical systems.

The four new members of the PIC16F1579 family come in 14 to 20-pin packages with up to 28 kB of Flash and feature CIPs that enable functions in a broad range of applications, such as LED lighting and motor control. They are the 8-bit PIC MCUs with four 16-bit PWMs, each with independent timers for flexible output and signal-generation functions, including edge, centre-aligned and other output modes. System-communication functions are supported via serial interfaces for LIN and DMX connectivity, while the family’s intelligent analogue integration enables signal and sensor interface functions.
