CMS66 Product Family CMS’s CMS66 family of 8-bit OTP-based microcontrollers. It uses a fully static CMOS design technology bines higher speeds with the low power and high noise immunity. On chip memory system includes 1.0K bytes of OTP ROM, and 67bytes of static RAM 2. Description - On chip ROM size : 1K x14bits for CMS66P01/02/47/22/23 - Internal RAM size : 67 x 8 bits for CMS66P01/02/47/22/23 - 46 single word instructions - 2-level stacks - Stop Mode Wakeup when a high to low change in any pin of P0 - P0/P1/P2 ports Pull-up Resistor can chosed by register - 8Bit x 3 channels (66P01) ADC 8Bit x 4 channels (66P02/47) ADC 8Bit x 8 channels (66P22/23) ADC - 1parators with + input can connected to GND (66P01) 2 parators with + input can connected to GND(66P02/47/22/23) - Operating voltage LV XT MODE(455K): 2.1~3.6V XT MODE(4M): 2.5 ~ 5.5V RC MODE: 2.1 ~ 5.5 V Internal RC: 2.5~5.5V - Operating frequency 5V : 0 ~ 10 MHz 2.1V : 0 ~ 2 MHz - The most fast execution time is 400ns under 10 MHz in all single cycle instructions except the branch instruction - Low Votage detector Reset (LVR) - Stop Mode for power saving(WDT always run and the power current less than 3u A@3V) - 8-bit real time clock/counter(RTCC) with 8-bit programmable prescaler - 4 types of oscillator can be selected by programming OTP ROM: R C L o w cost RC oscillator INTRC Internal R and C oscillator XT Standard crystal oscillator http;//.mcu..cn P. 3 MAR-2008 VER1.1 CMS66P01/02/47/22/23 LVXT Low voltage crystal oscillator - 3 oscillator start-up time can be selected by programming OTP ROM(@VCC = 5V) : 560µs, 2.2ms, 9 ms - On-chip RC oscillator based Watchdog Timer(WDT) always run - All pins with their own independent direction control 5 I/O + 1 Input for CMS66P01 13I/O + 1 Input for CMS66P02 15 I/O + 1 Input for CMS66P47 21 I/O + 1 Input for CMS66P22 25 I/O + 1...
