| CR16MUS944V9 Description | The family of CompactRISC? microcontrollers are general-purpose 16-bit microcontrollers 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 family of CompactRISC 16-bit microcontrollers offer 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 20 million instructions per second (MIPS) at a clock rate of 24MHz. In the following text, device is alsays refered to the family of CompactRISC 16-bit microcontrollers. For the exact feature set, check individual datasheets. The device is available in a variety of package sizes and types. All devices have 48 kbytes of reprogrammable flash program memory, 1.5 kbytes of ISP memory, 2 kbytes of static RAM, and 640 bytes of non-volatile EEPROM data memory. The 80-pin device has two USARTs, two 16-bit multi-function timers, one SPI/MICROWIRE-PLUS? serial interface, an 8-channel A/D converter, two analog comparators, WATCHDOG? protection mechanism, and up to 48 general-purpose I/O pins. The 44-pin devices offer the same basic features as the 80-pin device, but with fewer I/O ports and peripheral modules due to the smaller number of available pins. All devices operate with a high-frequency crystal as the main clock source. Some packages allow the device to operate with either the main clock source or with a slow (32.768 KHz) oscillator in Power Save mode. The device supports several Power Save modes wh |
