The Intel MCS-51 is a single chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the instruction set of the Intel MCS-51 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 an example of a complex instruction set computer, and has separate memory spaces for program instructions and data.
SuperH is a 32-bit reduced instruction set computing (RISC) instruction set architecture (ISA) developed by Hitachi and currently produced by Renesas. It is implemented by microcontrollers and microprocessors for embedded systems.
H8 is the name of a large family of 8-bit, 16-bit and 32-bit microcontrollers made by Renesas Technology, originating in the early 1990s within Hitachi Semiconductor. An administrator on the Renesas user community boards commented in 2011 that there are no plans for further development of H8 based products. The family of largely CISC machines is unrelated to the higher-performance SuperH family of 32-bit RISC-like microcontrollers.
The MSP430 is a mixed-signal microcontroller family from Texas Instruments. Built around a 16-bit CPU, the MSP430 is designed for low cost and, specifically, low power consumption embedded applications.
Renesas Electronics Corporation TYO: 6723 is a Japanese semiconductor manufacturer headquartered in Tokyo. It has manufacturing, design and sales operations in around 20 countries. It was the world's largest auto semiconductor maker in 2014, and the world's largest maker of microcontrollers. It also makes mixed-signal integrated circuits and system on a chip.
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide two (556) or four (558) timing circuits in one package.
V850 is the trademark name for a 32-bit RISC CPU architecture of Renesas Electronics for embedded microcontrollers, introduced in early 90's by NEC and still being developed as of 2018.
V850 Family has been evolved by many microarchitecture extensions until today, but all the extensions have binary code level backward compatibility of programs across a quarter century. Its basis is 32 of 32-bit general-purpose registers with load/store architecture. It has high code efficiency because most of frequently used instructions are mapped into 16-bit half-word.
In its earlier stage, it mainly focused on ultra-low power consumption such as 0.5 mW/MIPS. V850 has been widely used in variety of applications including: optical disk drives, hard disk drives, mobile phones, car audio and inverter compressors for air conditioners. But today, new microarchitectures are mainly toward high performance and high reliability with such as dual-lockstep redundant mechanism for automotive industry. Nowadays, V850 Family and RH850 Family are comprehensively used in a car.
V850 Family and RH850 Family has huge assets of software and development tools such as ITRON based RTOS, AUTOSAR (OSEK/VDX) based RTOS, famous RTOS, compilers, automated code reviewers, virtual platform with instruction set simulators, debuggers, and both full probing-pod-based and JTAG-based in-circuit emulators.
The Renesas R8C is a 16-bit microcontroller that was developed as a smaller and cheaper version of the Renesas M16C. It retains the M16C's 16-bit CISC architecture and instruction set, but trades size for speed by cutting the internal data bus from 16 bits to 8 bits. It is available in a number of different versions with varying amounts of flash memory and SRAM.
IEBus is a communication bus specification "between equipments within a vehicle or a chassis" of Renesas Electronics. It defines OSI model layer 1 and layer 2 specification. IEBus is mainly used for car audio and car navigations, which established de facto standard in Japan, though SAE J1850 is major in United States.
IEBus is also used in some vending machines, which major customer is Fuji Electric.
Each button on the vending machine has an IEBus ID, i.e. has a controller.
Detailed specification is disclosed to licensees only, but protocol analyzers are provided from some test equipment vendors.
Its modulation method is PWM with 6.00 MHz base clock originally, but most of automotive customers use 6.291 MHz, and physical layer is a pair of differential signalling harness. Its physical layer adopts half-duplex, asynchronous, and multi-master communication with CSMA/CD for access control. It allows for up to fifty units on one bus over a maximum length of 150 meters. Two differential signalling lines are used with Bus+ / Bus− naming, sometimes labeled as Data(+) / Data(−).
The Toshiba TLCS series is a family of CISC and RISC microcontrollers from Toshiba.
A digital signal controller (DSC) is a hybrid of microcontrollers and digital signal processors (DSPs). Like microcontrollers, DSCs have fast interrupt responses, offer control-oriented peripherals like PWMs and watchdog timers, and are usually programmed using the C programming language, although they can be programmed using the device's native assembly language. On the DSP side, they incorporate features found on most DSPs such as single-cycle multiply–accumulate (MAC) units, barrel shifters, and large accumulators. Not all vendors have adopted the term DSC. The term was first introduced by Microchip Technology in 2002 with the launch of their 6000 series DSCs and subsequently adopted by most, but not all DSC vendors. For example, Infineon and Renesas refer to their DSCs as microcontrollers.)
The Mitsubishi 740, also known as MELPS 740, was a series of 8-bit CMOS microcontrollers and microprocessors with an enhanced MOS Technology 6502 compatible core. The ICs were manufactured by Mitsubishi Electric during the 1980s and 1990s.
In computer architecture, 16-bit integers, memory addresses, or other data units are those that are 16 bits wide. Also, 16-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 16-bit microcomputers are computers in which 16-bit microprocessors were the norm.
LPC is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors. The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals. The earliest LPC series were based on the Intel 8-bit 80C51 core. As of February 2011, NXP had shipped over one billion ARM processor-based chips.
NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 32-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSes are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply embedded environments – such as fork.
RL78 Family is a 16- and 8-bit CPU core for embedded microcontrollers of Renesas Electronics introduced in 2010. The basis of RL78 Family is an accumulator-based register-bank CISC architecture with 3-stage instruction pipelining. It has 20-bit 1M Byte address space.

78K is the trademark name of 16- and 8-bit microcontroller family manufactured by Renesas Electronics, originally developed by NEC started in 1986. The basis of 78K Family is an accumulator-based register-bank CISC architecture. 78K is a single-chip microcontroller, which usually integrates; program ROM, data RAM, serial interfaces, timers, I/O ports, an A/D converter, an interrupt controller, and a CPU core, on one die.
