Technology Inc. is expanding its 8-bit segmented LCD
microcontroller (MCU) family with five new devices-the PIC16LF1902/3/4/6/7 (PIC16LF190X) MCUs. The PIC16LF190X
family supports many general-purpose applications and enables the
implementation of LCD into low-power and cost-sensitive designs, such as
security tokens, smart cards, medical devices, home appliances, key fobs or any application involving a segmented LCD.
Featuring eXtreme Low Power (XLP) technology for sleep currents down to 20 nA, and
a typical active current of 35 microamperes per MHz, the MCUs extend battery
life, while maintaining accurate timing with a RTC and driving a segmented LCD.
The PIC16LF190X includes up to 14 KByte of Flash
program memory, up to 512 Bytes of RAM, up to 14 10-bit Analog-to-Digital
Converter (A dc) channels, serial communication, temperature indicator and the
capability to drive up to 116 LCD segments.
With the addition of XLP technology
for extended battery life, and capabilities such as utilizing the integrated
temperature indicator to provide crystal-accuracy compensation, low-power RTC
support and low voltage-detect support utilizing the internal A dc and voltage
reference, the MCUs enable low-cost LCD solutions for portable devices.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
