(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 ) Tuesday introduced the first four devices of its new PIC18CXXX 8-bit 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. microcontroller architecture: the PIC18C242, PIC18C442, PIC18C252 and PIC18C452. With the enhanced performance of the new PIC18CXXX architecture, these 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 ) devices provide an ideal solution for system-on-a-chip (SOC) and system partitioning capability in embedded applications. The new PIC18CXXX architecture is an enhanced RISC core that is upward compatible from Microchip's Mid-Range PIC12C6XX and PIC16CXXX core and High-End PIC17CXXX core, providing a seamless migration path of software code to higher integration. The PIC18CXXX architecture offers up to two million bytes of program memory address space, a C compiler friendly development environment and industry-leading 10 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. performance at 40 MHz. Microchip will continue to support its current PICmicro architecture along with the new PIC18CXXX architecture. The PIC18C242 and PIC18C442 feature 8,192 x 16 bits of OTP program memory and 512 bytes of user RAM. The PIC18C252 and PIC18C452 offer 16,384 x 16 bits of OTP program memory and 1,536 bytes of user RAM. The PIC18C242 and PIC18C252 are available in 28-pin PDIP (Plastic DIP) See DIP. and SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. packages, and the PIC18C442 and PIC18C452 are available in 40- and 44-pin PDIP, PLCC (Plastic Leaded Chip Carrier) A plastic, square, surface mount chip package that contains leads on all four sides. The leads (pins) extend down and back under and into tiny indentations in the housing. See chip package. and TQFP See QFP. packages. All four devices contain high precision analog peripherals, including 5- to 8-channel 10-bit (+/- 1 LSB) analog-to-digital converters, programmable low-voltage reset and 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. detect. The microcontrollers feature 23-34 I/O pins, high-performance communication capability through USART/I2C(TM)/SPI(TM), two 10-bit pulse-width modulation, three 16-bit timers, one 8-bit timer, watchdog timer, wide 2.5-5.5 operating voltage, capture/compare/pulse-width modulation and Phase Lock Loop. The PIC18CXXX enables system partitioning and low-cost system-on-a-chip (SOC) capability in embedded systems designs. Leading engineers are carefully partitioning the embedded hardware into digital logic that can take advantage of high integration and flexible non-volatile memory-based software to meet demands for user interfaces which can change rapidly. The PIC18CXXX provides designers with a single-chip system solution that complements the digital logic by merging the flexibility of OTP memory with advanced analog functionality at a competitive 8-bit microcontroller price. This optimizes the performance of a 32-bit microprocessor, digital signal processor A digital signal processor (DSP) is a specialized microprocessor designed specifically for digital signal processing, generally in real-time computing. Characteristics of typical Digital Signal Processors
Applications for these devices are wide ranging and may include anti-lock braking systems, vehicle active suspension, fuel pump controller, fuel injection, manufacturing equipment, instrumentation and monitoring, data acquisition, power conditioning, thermostats, environmental monitoring, telecommunications and consumer audio/video. Microchip's PICmicro OTP and Flash microcontrollers feature In-Circuit Serial Programming(TM) (ICSP ICSP In Circuit Serial Programming (MicroCHIP) ICSP International Committee on Systematics of Prokaryotes ICSP International Conference on Signal Processing ICSP Interagency Committee on Standards Policy (TM)), which allows the microcontroller to be programmed after being placed in a circuit board. This offers tremendous flexibility, reduces development time and manufacturing cycles, and improves time to market. ICSP also enables reduced cost of field upgrades, system calibration during manufacturing, the addition of unique identification codes to the system and calibration of the system in the field. Requiring only two I/O pins for most devices, Microchip offers the most non-intrusive programming available today. PIC18CXXX Development Systems The PIC18CXXX is supported by the MPLAB(TM)-C18 C Compiler, a complete high-level language compiler for the new PIC18CXXX 8-bit RISC microcontroller architecture. The compiler is expected to be available August 1999 for $495 each. A 30-day full-featured demo of MPLAB-C18 can be downloaded from Microchip's web site www.microchip.com at no cost starting in July. The MPLAB-ICE 2000 Universal In-Circuit Emulator provides high-performance real-time emulation for the PIC18CXXX. The system features the sophisticated MPLAB Integrated Development Environment See IDE. integrated development environment - interactive development environment . Interchangeable processor modules and device adapters allow the emulator system to be easily configured to emulate different processors. MPLAB-ICE 2000 emulates voltages as low as 2.0 volts and can emulate at full speed. Operating in the Microsoft Windows(R) environment, MPLAB gives users the flexibility to edit, compile and emulate all from a single user interface--at no additional cost. Pricing for MPLAB-ICE 2000 starts at $1,995. Microchip offers additional support, including development and programming tools. Pricing and Availability Pricing in 10,000-unit quantities is $6.16 each for the PIC18C242, $6.79 each for the PIC18C442, $6.70 each for the PIC18C252 and $7.41 each for the PIC18C452-04/P. These four devices are being implemented with industry standard industrial temperatures. Samples are planned for August 1999 with volume shipments expected third quarter 1999.
