It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. H8SX/1544F microcontroller provides an enhanced CAN-compatible controller, 512-Kbyte single-cycle-accessible flash memory, and much more Renesas Technology Renesas Technology Corporation (ルネサス テクノロジ| America, Inc. today announced the H8SX/1544F, a 32-bit complex instruction set computer (CISC (Complex Instruction Set Computer) Pronounced "sisk." The traditional architecture of a computer which uses microcode to execute very comprehensive instructions. ) microcontroller (MCU (1) (MicroController Unit) A computer on a single chip. See microcontroller. (2) (Multipoint Control Unit) A device that is used to moderate a videoconference of three or more end points (users at computers or groups of users ) for automotive applications. It is particularly well suited for sophisticated meters and control functions such as high-performance instrumental clusters such as a speedometer speedometer, instrument that indicates speed. A cable from an automotive speedometer is attached to the rear of the transmission of an automobile; the cable turns at a rate proportional to the speed of the car. , a tachometer tachometer (tăkŏm`ətər), instrument that indicates the speed, usually in revolutions per minute, at which an engine shaft is rotating. , a fuel and temperature meter, etc. To simplify and improve the design of embedded in-vehicle systems See automotive systems. , the new 40MHz device incorporates an enhanced two-channel local area network (LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. ) controller compatible with the controller area network (CAN) standard, a 512-kilobyte (KB) flash memory that can be accessed in one cycle at full clock speed, and a stepping motor control timer with a driver that can drive the motors of up to six gages of meters simultaneously. The MCU also offers many other essential peripheral and communication functions. "Besides instrumental clusters, the H8SX/1544F is an excellent semiconductor solution for gateways, factory automation equipment and a wide range of other in-vehicle embedded control systems, networked or standalone," said Paul Fox
Sir Paul Fox, CBE, is a British television executive, who spent much of his broadcasting career working for BBC Television, most prominently as the Controller of BBC One between 1967 , marketing director of the automotive business unit at Renesas Technology America, Inc. "This extended-temperature device (-40 degrees C to +105 degrees C) is the second-phase product for automotive applications in our popular H8SX family of MCUs, a growing product line based on a proprietary Renesas 32-bit architecture." The hardware functions built-into the H8SX/1544F ease and simplify the design of in-vehicle control systems and greatly reduce the load on the CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. . The two-channel CAN controller is enhanced with a filtering function and other improvements that boost network performance and reliability in the noisy environments typically found in cars and trucks. Other peripheral functions include six 16-bit general-purpose timer channels, twelve 16-bit PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a timer channels, the previously mentioned stepping motor control timer, an 8-bit watchdog timer A clock circuit that keeps counting from a set number down to zero. If the event it is monitoring occurs before it reaches zero, it resets to the starting number and starts counting down again. , a 16-bit watch timer, a 16-channel 10-bit A/D converter (Analog/Digital converter) A device that converts continuously varying analog signals from instruments and sensors that monitor conditions, such as sound, movement and temperature into binary code for the computer. and a 2-channel 8-bit D/A converter. To produce warning tones and other audible alerts, the MCU also provides a 4-channel sound generator sound generator Artificial sound generator ENT A device used to produced an artificial voice, as required by Pts with laryngectomies for cancer . The device offers a variety of on-chip data communication functions for connecting to external devices: a 16-bit external bus extension function, three serial communication interface (SCI (Scalable Coherent Interface) An IEEE standard for a high-speed bus that uses wire or fiber-optic cable. It can transfer data up to 1GBytes/sec. (hardware) SCI - 1. Scalable Coherent Interface. 2. UART. ) channels, two synchronous serial communication unit (SSU SSU Small Subunit SSU Sonoma State University SSU Savannah State University (Savannah, Georgia) SSU Shawnee State University (Ohio) SSU Salisbury State University ) channels, a 2-channel I2C bus interface, and four DMAC DMAC Direct Memory Access Controller DMAC Data Management and Communications DMAC N,N-Dimethylacetamide DMAC Downtown Media Arts Center (Orlando, Florida) DMAC Direct Memory Access Control DMAC Direct Machining and Control channels for high-speed data transfers. The comprehensive system development support Renesas provides for H8SX MCUs includes a C-compiler, assembler, linkage editor, librarian, simulator, and debugger, all of which are available as an integrated software development environment with project management tools. The E6000H full featured emulator implements a powerful hardware development environment. The instruction set of the 32-bit H8SX CPU core is upward-compatible with that of Renesas Technology's current H8S family of 16-bit MCUs. This allows customers to reuse in H8SX designs the code originally written for devices in the H8S family, while obtaining approximately a four-fold overall increase in processing power and improving ROM code efficiency by about 20 percent. Renesas has ongoing plans for advanced semiconductor solutions for automotive in-vehicle control system applications, and the H8SX product line is being extended to meet evolving market needs. Among the devices being developed are models with more flash memory, versions with enhanced peripheral functions, and chips that use 80-pin packages.
