Eight-bit microcontrollers can now be used in a wider variety of applications thanks to the increased number of intelligent, interconnected CIPs that combine to perform functions autonomously, without the core. Because these functions are performed deterministically and reliably in hardware rather than software, the CIPs enable systems to achieve significantly higher performance than is typical with
8-bit microcontrollers, while also simplifying the design process and reducing memory costs. Furthermore, these two new families are available in packages ranging from 8 to 40 pins, thus reducing board footprint and operating within a wide voltage range of 1.8 to 5.5V. Both families offer Peripheral Pin Select, which allows for flexible pin assignment and board layout to minimize EMI and crosstalk. Target applications include consumer electronics, the Internet of Things, wearable technology, and high-security systems.

The four new members of the PIC16F1579 family are available in 14- to 20-pin packages with up to 28 KB of Flash memory and incorporate integrated circuits (ICs) that offer functionality in a wide range of applications, such as LED lighting and motor control. These are the first 8-bit PIC microcontrollers with four 16-bit PWMs, each with independent timers for flexible output and signal generation functions, including edge-aligned, center-aligned, and other output modes. System communication features include serial interfaces for LIN and DMX connectivity, while integrated smart circuitry 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 incorporate CIPs that offer features suitable for a wide range of applications, including consumer electronics, the Internet of Things, and high-security systems. They are the first microcontrollers to integrate an A/D converter with calculations and perform input interface and sensor functions, such as accumulation, averaging, and low-pass filter calculations, in hardware rather than software, allowing the CPU to enter sleep mode or perform other tasks. They are also the first PIC16 microcontrollers to leverage Microchip's eXtreme Low Power (XLP) technology with IDLE and DOZE modes to reduce active power consumption. Furthermore, they are the first 8-bit microcontrollers with Peripheral Module Disable, which completely removes peripherals from the power rail and clock tree for zero power loss. Other integrated CIPs, such as the Hardware Limit Timer, combine to facilitate the implementation of high-security functions.
The Curiosity development board (DM164137) is now available for $20 to simplify system design. The free downloadable MPLAB Code Configurator generates code at the touch of a button. It provides a visual representation of a microcontroller's peripherals, eliminating the need to read datasheets. It also simplifies CIP configuration and provides production-ready code, accelerating development efforts for both new and experienced users. The MPLAB XC8 compiler and standard Microchip programmers/debuggers are also available.
