- Ubicom's SX series is an 8 bit microcontroller which has unusually high speed, up to 75Mhz (75 MIPS), and a high degree of flexibility. Some users have referred to these microcontrollers as PICs on steroids. While Ubicom's SX micros are limited in variety, their high speed and additional resources allow programmers to create 'virtual devices' as required. Refer to Parallax's Web site for information, as they are the main distributor of these devices.

Zilog's (primary) microcontroller families, in chronological order:
- Zilog Z8 - 8-bit Harvard architecture ROM / EPROM / OTP microcontroller with on-chip SRAM.
- Zilog Z180 - Z80 based microcontroller; on-chip peripherals, but external memory; 1MB address space.
- Zilog eZ8 - Better pipelined Z8 with on-chip Flash memory; 2-3 times as clock cycle efficient as original Z8.
- Zilog eZ80 - Fast 8/16/24-bit Z80 with FLASH, SRAM, peripherals, and linear addressing of 16MB; 3-4 times as clock cycle efficient as original Z80.
For almost every bare microcontroller manufacturer, there are a dozen little companies repacking them into a more hobbyist friendly package. Their product is often an MCU preloaded with a BASIC interpreter, soldered onto a Dual Inline Pin board along with a power regulator and other goodies. PICs seem to be very popular here, possibly due to good static protection. More powerful examples (e.g. faster execution, more RAM and code space) seem to be based on Atmel AVR or Hitachi chips and now ARM.
Comfile Technology Inc.
Comfile Technology Inc. produces a series of microcontrollers branded as CUBLOC and CuTOUCH, using the Atmel ATmega128 processor. They are very price competitive, being aimed at industrial applications, and include some nice features such as Ladder Logic in addition to BASIC, a huge 80Kbyte program memory, and hardware pulse width modulation. Their focus in on developing industrial controllers which are fast, easy-to-use, and versatile. Comfile Technology's CuTOUCH is a visual Touch-screen controller that can be programmed in BASIC and Ladder Logic. This product is the first of its kind in the world yet.
Parallax, Inc.
- BASIC Stamp - The Big Name in BASIC microcontrollers. They are Microchip PICmicros programmed with an interpreter that processes the program stored in an external EEPROM. Several different modules are available of varying processing speeds, RAM, and EEPROM sizes. Most popular is the original BASIC Stamp 2 module. The BASIC Stamp is used by Parallax as a platform for introductory programming and robotic kits.
- SX-Key - Parallax's development tool for the SX line of microcontrollers, supporting every SX chip commercially available. Using free SX-Key software (Assembly language), or the SX/B Compiler (BASIC-style language) from Parallax, the SX-Key programming tool can program SX chips in-system and perform in-circuit source-level debugging.
This range of controllers is based upon Microchip PICmicro's programmed with a BASIC interpreter. Using internal EEPROM or Flash to store the user's program they deliver a single-chip solution and are quite inexpensive. A PICAXE programmer is simply a serial plug plus two resistors. Complete development software, comprehensive documentation and application notes are all available free of charge.
The BASIC-like programming language is almost identical to that used by Parallax's Basic Stamp 1 (BS1) but has been enhanced to support on-chip hardware and additional functionality. In common with the BS1 programming language, the PICAXE has support only for a limited number of variables and lacks block-structured programming constructs.
Initially targeted at the UK educational sector, use of the PICAXE has spread to hobbyists, semi-professionals and it can also be found inside commercial products. With its user base in many countries, the PICAXE has steadily gained a good international reputation.
ZX-24, ZX-40
The ZX series MCUs are based on the Atmel ATmega32 processor and run a Virtual Machine that features built-in multi-tasking, 32-bit floating point math and over 1K of RAM for user's programs. Multi-tasking facilitates a more structured approach to coding for interface devices that require prompt service, e.g. serial devices, infrared remotes, etc.
The programming language for the ZX series is ZBasic, a modern dialect of Basic modelled after Microsoft's Visual Basic. The biggest improvement over the typical MCU Basic dialect is parametrized subroutines/functions that support local variables. Strong type checking is another improvement that aids in writing correct programs more quickly.
Coridium ARMexpress
ARMexpress is the first of a new family of DIP-24 (stamp-sized) controllers that combine a 60 MHz ARM CPU with a built-in BASIC compiler to achieve new levels of performance in this form factor. This combination makes this simple to use but very fast controller a good choice for the prototype builder or system integrator. 40K of code and 40K of data are available to the user, and code speed rivals that of programs written in C. The dialect of BASIC conforms more to Visual BASIC, but has hardware extensions like PBASIC.
