Core Independent Peripherals Now
Available on PIC18 Family
The PIC18F “K40” family of microcontrollers (MCUs) is now
available from Microchip Technology Inc. (NASDAQ: MCHP),
a leading provider of microcontroller, mixed-signal, analog
and Flash-IP solutions. The family consists of 10 new devices
ranging from 16-128 KB of Flash memory with package
options covering 28-64 pins. These cost-optimized 8-bit
MCUs are the first PIC18 product family to offer Microchip’s
popular Core Independent Peripherals (CIPs).
CIPs provide developers with the ability to accomplish tasks
in hardware while freeing up the CPU to do other tasks or go
to sleep. This results in reduced power consumption, allows
for deterministic response time, and decreases firmware
development and validation time. The PIC18F “K40” features
the ADC with Computation (ADC2) — an intelligent Analog-
to-Digital Converter which, independent of the core, can
control data acquisition and signal analysis functions required
in sensor interface applications, such as capacitive touch
sensing.
The addition of CIPs to the PIC18F “K40” builds upon the
legacy of the successful PIC18F “K20” family. These new
devices are cost effective and offer up to 128 KB of Flash,
5V operation, EEPROM and extensive peripheral integration.
The devices include a full complement of Core Independent
Peripherals for safety-critical applications (CRC/Memory
Scan, WindowedWatchdog Timer, and Hardware Limit Timer),
up to seven hardware PWMs and multiple communications
interfaces. Additionally, the PIC18 “K40” family offers
Intelligent Analog peripherals including Zero Cross Detect
(ZCD), on-chip comparator and ADC2. The ADC2 handles the
signal analysis functions of averaging, filtering, oversampling
and automatic threshold comparison independent of the CPU.
These devices are well suited for a broad range of applications
and market segments including touch sensing, industrial
control, consumer, automotive and Internet of Things (IoT).
“Microchip continues to expand our 8-bit portfolio with new on-
chip peripherals for both the PIC® and AVR® architectures,”
said Steve Drehobl, vice president of Microchip’s 8-bit MCU
division. “The PIC18F ‘K40’ family combines large memories
with the Core Independent Peripherals and Microchip’s
MPLAB® Code Configurator (MCC) to significantly reduce
product development time and improve system performance.”

Highly Integrated AFE for Power Quality
Monitoring Saves Significant Design Time and
Cost Versus Custom Development
Analog Devices, Inc. (ADI) today introduced a highly
integrated polyphase analog front end (AFE) with power
quality analysis designed to help extend the health and life
of industrial equipment while saving developers significant
time and cost over custom solutions. Achieving extremely
accurate, high-performance power quality monitoring
typically requires customized development, which can be
expensive and time-consuming. TheADE9000AFE is an off-
the-shelf solution with embedded power quality algorithms
and integrated with high-performance analog-to-digital
converters (ADCs) in one single device. This integration
simplifies additional complex algorithm programming,
reduces cost and component count, and increases speed
to market while still achieving high accuracy and enabling
EN61000-4-30 Class S for power quality. Equipment
in factories, hospitals, commercial buildings, and other
settings is often susceptible to service interruption,
premature failure, and long-term damage caused by
disturbances and variations in the power supply, known as
pollution. In many cases, this pollution in the power supply
