As the complexity of applications increases, many designers are facing challenges such as handling multiple functions and interfacing with a wide range of system inputs and communications. The PIC16F183xx and PIC16F188xx products from Microchip feature a number of core independent peripherals (CIPs) that can be combined to perform a wide variety of functions with little or no core involvement. This integration allows interconnections that bring a new level of interaction between peripherals, enabling unsurpassed flexibility in creating functions for a wide range of applications including consumer electronics, Internet of Things (IoT), safety critical, and wearable technology. These products also incorporate new power conserving functionality, including IDLE / DOZE operating modes and peripheral module disable (PMD), in addition to eXtreme low power (XLP) technology.

Increased Low-Power Functionality

New IDLE and DOZE low-power modes allow applications to optimize device performance and power consumption. The PMD allows unused peripherals to be turned off individually, further reducing power consumption.

Safety and Monitoring

Using the integrated windowed watchdog timer (WWDT) and cyclic redundancy check (CRC) peripherals simplifies the implementation of safety and system management functionality. These CIPs automate the monitoring hardware-based events as well as verify the integrity of program memory, data EE, and communications.

Flexible PCB Routing

The peripheral pin select (PPS) functionality allows for I/O pin remapping of the digital peripherals for increased flexibility and ease of PCB layout. Hardware utilization is also improved by enabling access to multiple peripherals from the same I/O port.

Communication

These products include SPI, I²C,™ and EUSART peripherals, which enable a wide range communication protocols. Using external modules, these peripherals enable other wired and wireless communications such as Ethernet, Wi-Fi, Bluetooth low energy, and LoRa™. This allows for intelligent applications where communication with a server in the cloud or with a host/master device is required.
