Lattice Semiconductor

Microchip Technology

Microchip produces microcontrollers with 3 very different architectures:

8-bit (8 bit data bus) PICmicro, with a single accumulator (8 bits):

  • PIC10 and PIC12: 12-bit instruction words
  • PIC16 series: 14-bit instruction words, one address pointer ("indirect register pair")
    • PIC16F628 (Replacement for very popular but discontinued PIC16F84)
    • PICAXE
  • PIC18 series: 16-bit instruction words, three address pointers ("indirect register pairs")

16-bit (16-bit data bus) microcontrollers, with 16 general-purpose registers (each 16-bit)

32-bit (32 bit data bus) microcontrollers:

National Semiconductor

NEC

Parallax

  • SX
    • These were formerly made by Ubicom. The SX die is still manufactured by Ubicom, who send it to Parallax for packaging
    • SX-18, 20, 28, 48 and 52 versions (Note that the SX-18 and SX-52 have been discontinued)
    • Parallax's SX series is an 8 bit microcontroller which has unusually high speed, up to 75 MHz (75 MIPS), and a high degree of flexibility. Andre LaMothe has proven that the SX-52 can actually be clocked to 80 MHz (80 MIPS) even though the specs say 75 MHz is the maximum. He has used the SX-52 in thousands of XGameStation development computers all running at 80 MHz. Some users have referred to these microcontrollers as PICs on steroids. While Parallax's SX micros are limited in variety, their high speed and additional resources allow programmers to create 'virtual devices', including complete video controllers, as required. Refer to Parallax's Web site for information, as they are the sole distributor of these devices.
  • Propeller
    • The Propeller is a 8-core 32-Bit microcontroller with 32kB internal RAM.
