Microchip has introduced two new 8-bit families that expand its growing family of innovative PIC MCUs with core-independent peripherals (CIP).
Because of the increasing number of these intelligent, interconnected CIPs, these CIPs can be combined to perform functions automatically without a core, so 8-bit MCUs can now be used in a wider range of applications.
Because these functions are performed deterministically and reliably in hardware rather than software, CIP can achieve system performance that far exceeds that of a typical 8-bit MCU, while simplifying the design experience and reducing memory costs. In addition, the two new families are available in 8 to 40-pin packages, reducing board space while providing a wide operating voltage range of 1.8 to 5.5V. Both series offer peripheral pin selection, which enables flexible pin mapping and PCB layout to minimize EMI and crosstalk. Example applications include consumer electronics, the Internet of Things (IoT), wearable technology, and safety-critical systems.
Four new members of the PIC16F1579 family are available in 14 to 20-pin packages with up to 28 KB of flash memory and CIPs that support a wide range of application functions such as LED lighting and motor control. They are 8-bit PIC MCUs with four 16-bit PWMs, each with independent timers for flexible output and signal generation functions, including edge, center-aligned, and other output modes. System communication is supported through a serial interface for LIN and DMX connections, while intelligent analog integration in this series enables signal and sensor interface functions.
The first 10 members of the PIC16F18877 family are available in 8- to 40-pin packages with up to 56 KB of flash memory and CIPs, which can implement functions in a wide range of applications, such as consumer electronics, IoT, and safety-critical systems. They were the first MCUs to integrate ADCs with calculations, and they performed input and sensor interface functions such as accumulation, averaging, and low-pass filter calculations in hardware instead of software, enabling the CPU to sleep or perform other tasks. They are also the first PIC16 MCUs to enhance Microchip's ultra-low power (XLP) technology with IDLE and DOZE modes to reduce active power consumption. In addition, they are the first 8-bit MCUs with peripheral modules disabled, which completely removes peripherals from the power rail and clock tree, enabling zero power consumption.
The Curiosity Development Board (DM164137) is available now to simplify system design. Free downloadable MPLAB Code Configurator generates code with the click of a button. It provides a visual representation of MCU peripherals, eliminating the need to read data tables. In addition, it facilitates the setup of CIP and provides code that can be used in production environments, thereby speeding up development for new and experienced users. The company said it also offers Microchip's MPLAB XC8 compiler and standard programmer / debugger.
