Freescale S08
The 9S08 (68HCS08 or S08 for short) is an 8-bit microcontroller (μC) family originally produced by Motorola, later by Freescale Semiconductor, and currently by NXP, descended from the Motorola 6800 microprocessor. It is a CISC microcontroller. A slightly extended variant of the 68HC08, it shares upward compatibility with the aging 68HC05 microcontrollers, and is found in almost any type of embedded systems. The larger members offer up to 128 KiB of flash, and 8 KiB of RAM via a simple memory management unit (MMU) which allows bank-switching 16 KiB of the address space and an address/data register pair which allows data fetches from any address. The paging scheme used allows for a theoretical maximum of 4 MB of flash. MMU-equipped variants offer two extra CPU instructions, CALL and RTC, which are used instead of JSR and RTS respectively when dealing with subroutines placed in paged memory, allowing direct page-to-page subroutine calls.

C8051
The Intel MCS-51 (commonly termed 8051) is a single-chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the Intel MCS-51 instruction set was John H. Wharton.. Intel's original versions were popular in the 1980s and early 1990s, and enhanced binary compatible derivatives remain popular today. It is a complex instruction set computer with separate memory spaces for program instructions and data. Intel's original MCS-51 family was developed using N-type metal–oxide–semiconductor ( NMOS) technology, like its predecessor Intel MCS-48, but later versions, identified by a letter C in their name (e.g., 80C51) use complementary metal–oxide–semiconductor (CMOS) technology and consume less power than their NMOS predecessors. This made them more suitable for battery-powered devices. The family was continued in 1996 with the enhanced 8-bit MCS-151 and the 8/ 16/32-bit MCS-251 family of binary compatible microcontrollers.

EZ80
The Zilog eZ80 is an 8-bit microprocessor designed by Zilog as an updated version of the company's first product, the highly-successful Zilog Z80. The eZ80 is binary compatible with the Z80, but it operates almost three times faster at the same clock frequency. Design The eZ80 has a three-stage pipeline: fetch, decode, and execute. When an instruction changes the program counter, it flushes the instructions that the CPU is currently processing. Available at up to 50 MHz (2004), the performance is comparable to a Z80 clocked at 150 MHz if fast memory is used (i.e. no wait states for opcode fetches, for data, or for I/O) or even higher in some applications (a 16-bit addition is 11 times as fast as in the original). The original Z80-compatible 16-bit register configuration is supported. The eZ80 also supports direct continuous addressing of 16 MB of memory without a memory management unit, by extending most registers (HL, BC, DE, IX, IY, SP, and PC) from 16 to 2 ...

STM8
The STM8 is an 8-bit microcontroller family by STMicroelectronics. The STM8 microcontrollers use an extended variant of the ST6 and ST7, ST7 microcontroller architecture. STM8 microcontrollers are particularly low cost for a full-featured 8-bit microcontroller. Architecture The STM8 is very similar to the earlier ST7, but is better suited as a target for C (programming language), C due to its 16-bit index registers and stack pointer-relative addressing mode. Although internally a Harvard architecture it has "memory bridge" that creates a unified 24-bit address space, allowing code to execute out of RAM (useful for in-system programming of the flash ROM), and data (such as lookup tables) to be accessed out of ROM. On access the "memory bridge" stalls the CPU if required so that RAM-like write access to the flash ROM is possible. Code execution from the EEPROM is denied and creates a reset event. Random access to data above 64K is limited to special "load far" instructions; most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
