Microchip Technology advances world's smallest MCUs with A/D converter.CHANDLER, Ariz.--(BUSINESS WIRE)--Feb. 3, 1997--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 supplier of field-programmable 8-bit microcontrollers, serial EEPROMs and other products for embedded control applications, Monday announced it has integrated analog-to-digital converter technology into its revolutionary 8-pin microcontroller family--the world's smallest microcontrollers. The PIC12C671 and PIC12C672 8-bit one-time-programmable (OTP (1) (One Time Programmable) Refers to programming content or logic into chips such as EPROMs and EEPROMs, which cannot be reversed. See antifuse. (2) (One Time P ) microcontrollers provide intelligence, data acquisition and mixed-signal capability to new applications where this performance was not previously possible because of cost and space constraints. These 8-pin microcontrollers allow easy integration of first-time intelligent features into electromechanical The use of electricity to run moving parts. Disk drives, printers and motors are examples. Electromechanical systems must be designed for the eventual deterioration of moving components that wear over time. The first TVs were electromechanical systems (see video/TV history). designs and will compete directly with 4-bit microcontroller products while providing significantly enhanced performance. The advanced analog features include an on-chip analog-to-digital converter and four analog channels, which are ideally suited to measure environmental conditions, such as temperature, pressure, motion and voltage. The PIC12C671 and PIC12C672 feature 1,024 words of program memory and 2,048 words of program memory, respectively, along with 128 bytes of user RAM. These devices offer six multiplexed I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output pins with on-chip clock oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air (4 MHz (MegaHertZ) One million cycles per second. 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. ), 35 single-word instructions, full-speed 1 ms instruction cycle at 4 MHz, eight-level deep hardware stack, 8-bit real time clock/counter with 8-bit programmable prescaler, watchdog timer, direct LED drive, low 2.5-5.5 operating voltage and <2 mA @ 5 volts, 4 MHz low power consumption. In-circuit serial programming of the OTP microcontroller offers a true, self-contained intelligent system on a chip. The PIC12C671 and PIC12C672 target applications in which the environment (pressure, temperature, motion, acceleration, gas concentration and sound) is being monitored and/or measured in a variety of products, such as smart sensors, intruder detectors, security systems, tire pressure gauges, water meters, CO detectors, exhaust systems, smoke detectors, portable voice recorders, intelligent thermostats, rheostats, safety devices for consumers products, automatic temperature shutoff shut·off n. 1.

These devices provide a high performance low-cost replacement of many electro-mechanical applications. "Many designers looking for Looking for In the context of general equities, this describing a buy interest in which a dealer is asked to offer stock, often involving a capital commitment. Antithesis of in touch with. general-purpose microcontrollers do not want the cost of unneeded peripherals and large pin counts typically found on many 4-bit and 8-bit devices," said Damon Chu, Microchip's strategic marketing manager. "In May 1996, the first two products of the PIC12CXXX family were announced and are now in volume production. Today, Microchip announces extensions of the product family as we promised. "The PIC12C671 and PIC12C672 provide mathematical and Boolean performance not available on most 4-bit microcontrollers. They also offer an on-chip analog-to-digital converter which enables engineers to design low cost mixed-signal, intelligent sensing and embedded control systems in an 8-pin package. Again, these OTP microcontrollers provide an extremely cost effective and flexible design alternative to higher pin-count and ASIC (Application Specific Integrated Circuit) Pronounced "a-sick." A chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor. devices." With seven additional devices planned for introduction during the next 12 months, the 8-pin PIC12CXXX family will provide a full range of features, including on-chip clock oscillator; serial I/O ports; on-chip sensors; flash memory technology for rewriteable program memory; nonvolatile EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. , 1.8 volt operation; and direct LED drive. Future products will offer enhanced EPROM EPROM in full erasable programmable read-only memory Form of computer memory that does not lose its content when the power supply is cut off and that can be erased and reused. program memory, RAM data memory and a suite of analog peripherals, such as comparators and analog-to-digital converters. All 8-pin products are pin-for-pin compatible within the PIC12CXXX family. Each PIC12CXXX device is code compatible with Microchip's popular larger lead count PIC16/17 8-bit OTP MCU (1) (MicroController Unit) A computer on a single chip. See microcontroller.
