CR16MCS9VJE8 Description

    The family of 16-bit CompactRISC™ microcontroller is based on a Reduced Instruction Set Computer (RISC) architecture. The device operates as a complete microcomputer with all system timing, interrupt logic, flash program memory or ROM memory, RAM, EEPROM data memory, and I/O ports included on-chip. It is ideally suited to a wide range of embedded controller applications because of its high performance, on-chip integrated features and low power consumption resulting in decreased system cost.

    The device offers the high performance of a RISC architecture while retaining the advantages of a traditional Complex Instruction Set Computer (CISC): compact code, on-chip memory and I/O, and reduced cost. The CPU uses a three-stage instruction pipeline that allows execution of up to one instruction per clock cycle, or up to 25 million instructions per second (MIPS) at a clock rate of 24 MHz.

    The device contains a FullCAN class, CAN serial interface for low/high speed applications with 15 orthogonal message buffers, each supporting standard as well as extended message identifiers.

    The device has up to 64K bytes of reprogrammable flash EEPROM program memory or ROM memory, 1.5K bytes of flash EEPROM In-System-Programming memory, 3K bytes of static RAM, 2K bytes of non-volatile EEPROM data memory and 128 bytes with high endurance, two USARTs, two 16-bit multi-function timers, one SPI/MICROWIRE-PLUS™ serial interface, a 12-channel A/D converter, two analog comparators, WATCHDOG™ protection mechanism, and up to 56 general-purpose I/O pins.

    The device operates with a high-frequency crystal as the main clock source and either the prescaled main clock source or with a low frequency (32.768 kHz) oscillator in Power Save mode. The device supports several Power Save modes which are combined with multi-source interrupt and wake-up capabilities. This device also has a Versatile Timer Unit (VTU) with four timer sub-systems, a CAN interface, and ACCESS.bus synchronous serial bus interface.

    Powerful cross-development tools are available from National Semiconductor and third party suppliers to support the development and debugging of application software for the device. These tools let you program the application software in C and are designed to take full advantage of the CompactRISC architecture.

    In the following text, device is always referred to the family of 16-bit CAN-enabled CompactRISC Microcontroller.
