MIcrochip Technology Expands Its Family of Certified Full-Speed USB 2.0 PIC(R) Microcontrollers with More Cost-Effective and Smaller Options.CHANDLER, Ariz. -- Microchip Technology Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on : MCHP MCHP Maryland Children's Health Program MCHP Microchip Technologies (stock symbol) MCHP Micro-sized Combined Heat and Power (American Honda Motor Co. & Climate Energy, LLC) MCHP Maine Community Heritage Project ), a leading provider of microcontroller and analog semiconductors, today announced new Flash PIC(R) microcontrollers with certified Full-Speed USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. 2.0 connectivity and 48 megahertz (MHz) operation, for 12 megabits-per-second (Mbps) data-transfer rates. In combination with a wide variety of on-chip peripherals and nanoWatt Technology power management, these features provide a complete embedded-control solution for designers working with USB in industrial, medical and many other embedded applications. The majority of USB-capable microcontrollers are optimized exclusively for applications in the personal computing (PC) peripherals and consumer markets, leaving a real void for embedded designs. Microchip's USB PIC microcontroller family makes the benefits of Full-Speed USB available to a broader range of embedded applications that operate in harsh environments and only occasionally connect to personal computers. The new PIC18F4450/2450 Full-Speed USB microcontrollers help to address these needs by integrating USB as one of the primary serial interfaces, as opposed to the prevalent approach that adds a serial-to-USB patch on top of a legacy design. "Microchip's USB PIC microcontrollers can perform as the sole controller in embedded applications," said Mitch Obolsky, vice president of Microchip's Advanced Microcontroller and Architectures Division. "The new cost-effective USB family members announced today provide a Full-Speed compatible migration while maintaining a powerful 12 MIPS (Million Instructions Per Second) The execution speed of a computer. For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. RISC RISC in full Reduced Instruction Set Computing Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. core, self-programmable Flash memory and the power-saving features of our nanoWatt Technology." Example embedded applications that benefit from these Full-Speed USB PIC microcontrollers include: industrial (manufacturing tools, data loggers, scanners, smart displays, micro fuel cells, gambling-machine peripherals, RFID readers, robot-controller interfaces, industrial timers, gas-flow analyzers, cable-test fixtures); medical (voice-activated applications, advanced wheelchairs, research equipment automation); automotive (vehicle-network bus diagnostic tools, vehicle trace recorders (black boxes), ultrasonic sensors); battery-powered (handheld tools, sensors, security applications, remote controls, home automation); consumer (business-card scanners, white-board digitizers, voice recorders, uninterruptable power-supply systems, MP3 players, fire alarms, security-system programmers). The two new USB PIC microcontrollers feature 16 Kbytes of self-programmable Enhanced Flash memory, which allows field upgrades for end applications via the USB port. Microchip's advanced PMOS (Positive channel MOS) Pronounced "p-moss." A type of microelectronic circuit in which the base material is positively charged. PMOS transistors were used in the first microprocessors and are still used in CMOS. Electrically Erasable Cell (PEEC PEEC Pocono Environmental Education Center (Pennsylvania) PEEC Partial Element Equivalent Circuit PEEC Programmed Escape from the Evolution of Cancer PEEC Provincial Environmental Education Centers ) Flash technology provides high endurance of up to 100,000 erase/write cycles and long data retention of more than 40 years. In addition, their Full-Speed USB 2.0 interface includes an onboard transceiver for direct data transfers to external peripherals with minimum 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. overhead. Other key features include: --768 bytes of RAM, 256 bytes of which can be a dedicated USB buffer --AUSART for RS232 and RS485 serial interfaces --10-bit Analog-to-Digital Converter with high accuracy (+/- 1 LSB) and up to 13 input channels --Capture/Compare/PWM module with 16-bit capture and resolution --Three Timers (2 x 16-bit, 1 x 8-bit) --Programmable Brownout A lowering of AC power voltage for some period of time. Brownouts can be very harmful to electronic equipment if sustained for long periods. Brownouts can cause flickering or a dimming on screen, and the computer may experience intermittent problems as a result. See blackout. Reset and Low Voltage Detect circuits --Enhanced In-Circuit Debugging capabilities with up to three hardware breakpoints Development Support An area of major concern for most new USB-application designers is the quantity and quality of available firmware support. Microchip has an extensive set of libraries for the most common application classes, including the Human Interface Device (HID), Communication Device Class (CDC See Control Data, century date change and Back Orifice. CDC - Control Data Corporation ) and custom drivers. Recognizing the need for migration from legacy applications, Microchip has published application note number AN956 "Migrating Applications to USB from RS-232 UART (Universal Asynchronous Receiver Transmitter) The electronic circuit that makes up the serial port. Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice with Minimal Impact on PC Software" at www.microchip.com/usb. The new USB PIC microcontrollers are also supported by Microchip's world-class development systems, including: MPLAB(R) Integrated Development Environment See IDE. integrated development environment - interactive development environment (IDE), MPLAB C18 C Compiler, MPLAB ICD ICD International Classification of Diseases (of the World Health Organization); intrauterine contraceptive device. ICD abbr. 2 In-Circuit Debugger and MPLAB PM3 Universal Device Programmer. In addition, the PICDEM(TM) Full-Speed USB Demo Board (part # DM163025), and MPLAB ICE 2000 and MPLAB ICE 4000 In-Circuit Emulator processor modules (part # PCM18XR0), which ease development with this family's advanced USB features, are available now.
