National Semiconductor's 16-bit RISC Microcontroller Features Integrated High Endurance Flash Programming.Business Editors/High-Tech Writers SANTA CLARA, Calif.--(BUSINESS WIRE)--Feb. 20, 2001 Boasts High Performance, On-Chip Integrated Features, and Low Power Consumption for a Wide Range of Embedded Controller Controller circuitry built into a device or on the main system board, in contrast with a removable card or module. Applications National Semiconductor Corporation (NYSE:NSM) today introduced a new CompactRISC(TM) microcontroller, the CR16MCS9, a general-purpose 16-bit microcontroller that is ideally suited for a wide range of embedded controller applications. Because of its high performance, low power consumption, on-chip memory, wide range of peripheral functions, and Reduced Instruction Set The repertoire of machine language instructions that a computer can follow (from a handful to several hundred). It is a major architectural component and is either built into the CPU or into microcode. Instructions are generally from one to four bytes long. Computer (RISC) architecture, this microcontroller will enable customers to reduce system costs significantly. Designed to fit the requirements of the communication, industrial control, and automotive industries, the CR16MCS9 operates as a complete, self-contained microcomputer with all system timing, interrupt logic, flash or ROM program memory, RAM, EEPROM data memory, and I/O ports included on-chip. At the heart of the microcontroller is a second generation CR16 CPU core module that has been extensively used at National in other CompactRISC-based designs. The CR16MCS9 features the high performance and reduced cost of a RISC architecture while retaining the advantages of a traditional Complex Instruction Set Computer See CISC.

The CPU uses a three-stage instruction pipeline that allows execution of up to one instruction per clock For each clock cycle. The phrase "the CPU does four instructions per clock" means that four machine instructions have been executed within one cycle of the CPU clock, the master clock that synchronizes everything in the computer. For example, in a 200MHz computer, each clock cycle is 5ns long (one billion nanoseconds divided by 200 million). See clock. cycle, or up to 25 million instructions per second (MIPS) at a clock rate See clock speed. of 25 MHz. The CR16MCS9 device contains a CAN 2.0B serial with 15 orthogonal message buffers, each supporting standard as well as extended message identifiers. Powerful cross-development tools are available from National Semiconductor and third party suppliers to support the development and debugging of application software for the CR16MCS9. These tools allow you to program the application software in C and are designed to take full advantage of the CompactRISC architecture. Also available is a TCP/IP Micro-Server evaluation kit that provides you with the platform and tools needed to evaluate the capabilities of the 16-bit microcontroller. The kit comes with a CR16MCS9VJE8 pre-programmed to allow you to view web pages right from the on-board memory of the chip, thus behaving as a "micro-server." You can manipulate peripherals included on the add-on card with a click of the mouse. Pricing and Availability The CR16MCS9 is available now in FLASH (CR16MCS9VJEx), FLASH/ROM Combo (CR16MCS9VJExy), or ROM (CR16MCS5VJExy) with extended, industrial, and commercial temperature range options. Available in an 80-pin PQFP package, the CR16MCS9 is priced at $11.00 each in 1,000-unit quantities. The evaluation kit, CR16-CB80-DPE DPE - Dangerous Pile or Embankment (ground condition) DPE - Data Processing Engineer DPE - Data Processing Equipment DPE - Decoupled Parameter Estimation DPE - Defensive Planning and Execution DPE - Department of Physical Education (formerly Office of Physical Education; US Military Academy) DPE - Department of Postsecondary Education DPE - Designated Pilot Examiner (conducts FAA checkrides) DPE - Developer and Platform Evangelist (Microsoft), sells for $199.00.
