Families


This page gives an overview some of the most common micro-controller families. It is by no means complete, nor is it guaranteed to be up-to-date or accurate.

Glossary Of Abbreviations



The follow abbreviations are use:



MHz     Maximum oscillator frequency (x internal clock "doubling")

mA*     current consumption per MHz (standby/active)

KHz     Oscillator frequency range

WDT     Watchdog timer

OWD     Oscillator Watchdog

BOD     Brown-out detector

IRQ     Interrupt sources (not all external)

RTC     Real time clock (time/date)

PWM     Pulse width modulators (effectively digital-to-analogue converte

ADC     Analogue-to-digital converters (channels x bits)

CMP     Analogue comparator input

REF     ADC reference

EE      Bytes of on-chip EEPROM

ENH     Enhanced UART

I2C     I-squared-C serial bus interface

CAN     Control Area Network bus

EM66 Series


EM-MARIN


Em-Marin: Not one of the most well known companies for micro-controllers, but never-the-less an interesting one.

In summary, the common features are: 72 instructions, 2 clock cycles per instruction, 16 bit ROM, 4 bit RAM, 8-bit EEPROM, software watchdog timer, analogue watchdog, tone generator, and very low power consumption with oscillators in the KHz rather than MHz.
