Microchip dsPIC 30F3011 Jeff Piasecki The dsPIC 30F3011 by Microchip is a 16-bit microcontroller with digital signal processing capabilities. This controller runs at a full clock speed of 40MHz. Single clock cycle DSP operations are available which allow for real-time digital filtering and digital control algorithms that otherwise would not be possible. Hardware peripherals for motor control applications include 6 PWM outputs and inputs for feedback from encoders. These motor control peripherals can be used independently for controlling up to 6 motors or combined for three-phase motors. Built in hardware for motor control and feedback eliminates interfacing to dedicated ICs for these tasks. A good mix of the usual hardware timers, counters and communications peripherals are also present.

BASIC Stamp 2 Module Bradley Levin The BASIC Stamp 2 (BS2-IC) Module is a fairly versatile MC. Its 20 Mhz CPU can read about 4000 instructions of

PBASIC

code per second. It has the widest support base of free material on the web and from Parallax. It can withstand temperatures from 40 below zero to just below the boiling point of water (185° F) making it a favorite for many single input monitoring solutions, such as environmental sensors or robots. It has 16 I/O pins not counting two (2) dedicated Serial pins (1 input, 1 output), no onboard UART or SPI; it requires an A-to-D converter chip to handle non-digital inputs. Programming requires a DB9 Serial connection to any PC parallel port. Although it has no internal timer, it has a plethera of compatible components with which it can be integrated – including LEDs, servos, and a wide selection of sensors. It has a very low power consumption of 3 mA running and 50 μA sleeping. It has an onboard voltage regulator, so it can handle 9V battery DC or a wall transformer to get its 5V for power. Individual MCs cost $49 ($54 for the industrial version) for single units down to about $25 in bulk (10k pieces or more.)

Texas Instrument’s MSP430

Jeremy Setser • Ultra-low power processor debuted in November 2004 • Made for battery-run applications such as: mp3 players, heart rate monitors, watches, portable medical devices, etc.

• This processor has a “sleep-mode” which consumes virtually no battery power and can resume to full-system mode in less than one microsecond. It can be configured to go into this “sleep mode” at every possible moment to save on battery life.

• 16-bit, 16Mhz processor – 8 KB of flash and 256 bytes of RAM

Applications for mass production/Cost – EXCELLENT

Costs appox. $0.89 each •

Low-power, mobile applications – EXCELLENT

Goes into power save mode at every opportunity •

Speed – POOR

16MHz, 16 bit is slow compared to the state-of-the-art processors •

Overall processing capabilities – POOR

Slow speed, small flash (8K) and small RAM (128 bytes) •

Development time - FAIR

Has C Compiler. TI is a reputable company with excellent support & user groups, but the processor is brand new and there could be issues.

•

Integration with external peripherals – FAIR

16 I/O lines, 7 A/D (10-bit) channels, 4 serial ports, optional Ethernet, optional built-in LCD driver
