PIC18(L)F26/27/45/46/47/55/56/57K42

28/40/44/48-Pin, Low-Power High-Performance

Microcontrollers with XLP Technology

Description

The PIC18(L)F26/27/45/46/47/55/56/57K42 microcontrollers are available in 28/40/44/48-pin devices. These devices

feature a 12-bit ADC with Computation (ADC²) automating Capacitive Voltage Divider (CVD) techniques for advanced

touch sensing, averaging, filtering, oversampling and threshold comparison, Temperature Sensor, Vectored Interrupt

Controller with fixed latency for handling interrupts, System Bus Arbiter, Direct Memory Access capabilities, UART with

support for Asynchronous, DMX, DALI and LIN transmissions, SPI, I²C, memory features like Memory Access Partition

(MAP) to support customers in data protection and bootloader applications, and Device Information Area (DIA) which

stores factory calibration values to help improve temperature sensor accuracy.

• Windowed Watchdog Timer (WWDT)

- Variable prescaler selection

• Operating Voltage Range:

- 1.8V to 3.6V (PIC18LF26/27/45/46/55/56/

57K42)

- 2.3V to 5.5V (PIC18F26/27/45/46/47/55/56/

57K42)

• Temperature Range:

- Industrial: -40°C to 85°C

- Extended: -40°C to 125°C

- Variable window size selection

- Configurable in hardware or software

Power-Saving Functionality

• DOZE mode: Ability to run CPU core slower than

the system clock

• IDLE mode: Ability to halt CPU core while internal

peripherals continue operating

• SLEEP mode: Lowest power consumption

• Peripheral Module Disable (PMD):

Ability to disable unused peripherals to

minimize power consumption
