• 8051 – Intel then Everyone (8-bit old)
• PIC – Microchip (8, 16 & 32bit)
• AVR – Atmel (8 & 32bit)
• MSP430 – TI (low power 16-bit)
• ARM Cortex – ARM Limited (32 bit)
• 68HCSxx – Motorola/freescale-NXP (old)
• PSoC – Cypress (M8C, 8051,ARM)
• Nios II / MicroBlaze – Altera / Xilinx (sc)

Microcontroller Application Requirements

• Microcontroller and Support Circuitry
• Power Supply
• Application Software
• User Input/Output and Device Interfaces

Features found in Microcontrollers

• Central Processor (8, 16 or 32bit)
• Reset Control (Power-on, Brown out, Watchdog, Stack Overflow)
• Internal Oscillators and PLLs (2-Speed CLK, RTC)
• Program Memory (Factory Mask, OTP, EPROM, Flash)
• Static RAM Memory (Volatile Data Storage)
• EEPROM Memory (Non-Volatile User Configuration / Calibration)
• GPIO Pins
• Timers
• Interrupts (Internal, External)
• Parallel Bus Interfaces
• Serial Interfaces (UART, I2C, SPI, USB)
• Analog input and output (ADC, DAC, PWM, Comp, Op Amp, Cap Sense)
• Dedicated Logic
• Power Management
• In-Circuit Programming and Debug (self reprogramming)
