Combines data transmission security with power management
Microchip Technology Inc. announced a Flash, 8-bit PIC® microcontroller with a 3-channel, transponder analog front end and an integrated KEELOQ® cryptographic peripheral. Applications for the PIC16F639 include: Automotive (PKE, tire-pressure monitoring systems); Authentication (intelligent RFID, property and identity, hospital systems, computer access); Security Systems (door locks, gate openers, doggie doors, remote sensors and their intercommunication); and other general-purpose applications. Key features of the PIC16F639 microcontroller include: Precision 8 MHz internal oscillator with software clock switching, up to 3.5 Kbytes of Flash program memory, 128 bytes of RAM, 256 bytes of EEPROM, two analog comparators, one 8-bit timer, and one 16-bit timer. NanoWatt low-power and reliability features Include: Ultra Low Power Wakeup (ULPW), software-selectable Brownout Reset (BOR), Programmable Low Voltage Detect (PLVD), Wakeup Reset (WUR) feature, and Enhanced Watchdog Timer (EWDT). LF analog front end features include: three channels for omni-directional 125 kHz wireless communications, 3 mV input sensitivity, programmable antenna tuning, and battery-less operation.
Andrew Morris designed a circuit that could detect a stroke victim's groan and convert the sound into a signal so caregivers would know when help was needed.

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 radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
