Microchip produces microcontrollers with 3 very different architectures:
- 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)
- 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)
- PIC24: 24-bit instruction words
- dsPIC: based on PIC24, plus DSP functions, such as a single-cycle MAC (multiply–accumulate) into two 40-bit accumulators.
32-bit (32-bit data bus) microcontrollers:
- AM1 (MN101)
- AM2 (MN102)
- AM3 (MN103)
- These were formerly made by Ubicom, former Scenix Semiconductor. The SX die has been discontinued by Ubicom. Parallax has accumulated a large stock of the dies and is managing the 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 shown that the SX-52 can be overclocked to 80 MHz (80 MIPS); 5 MHz above the rated clock speed. 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.

Rockwell semiconductors (now called Conexant) created a line of 6502 based microcontrollers that were used with their telecom (modem) chips. Most of their microcontrollers were packaged in a QIP package.
Manufactures a line of 8-bit 8051-compatible microcontrollers, notable for high speeds (50–100 MIPS) and large memories in relatively small package sizes. A free IDE is available that supports the USB-connected ToolStick line of modular prototyping boards. These microcontrollers were originally developed by Cygnal. In 2012, the company introduced ARM-based mixed-signal MCUs with very low power and USB options, supported by free Eclipse-based tools.
