Cmsemicon CMS66P02
CMS66P01/02/47/22/23
1. CMS66 Product Family
CMS’s CMS66 family of 8-bit OTP-based microcontrollers. It uses a fully
static CMOS design technology combines 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
1Comparators with + input can connected to GND (66P01)
2 Comparators 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 3uA@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
