MK7A25P

MK7A25P 8Bit Microcontroller with 10bit ADC General Description The MK7A25P is an 8 bit RISC high performance microcontroller with 10bit A/D converter. It is equipped with 2K word OTP(One Time Programmable) ROM, 128 Bytes RAM, Timer/Counter, Capture, Interrupt, LVR(Low Voltage Reset), I/O ports and PWM output in a single chip. 1. Feature z z z z z ROM size: 2K x 16 bits RAM: 37 x 8 bits(Special Purpose Register) + 128 x 8 (General Purpose Register) STACK: 8 Levels One instruction build by two systems clock. Reset mode: (a) Power-On reset (b) Low voltage reset (c) RESETB/PC1 (if be set as reset pin) input a negative pulse. (d) Watchdog timer count overflow reset z Dual Clock Mode - External RC or Crystal oscillator - Internal 4MHz RC oscillator z Timer/counter: 3 units. - TM1: 16-bit, capture & Timer. - TM2: 8-bit, PWM (period) & Timer. - TM3: 8-bit, PWM (duty) & Timer. - TO : TM2(PWM) clock out z Watchdog Timer: On chip WDT is based on an internal RC oscillator (for WDT used only). Have 8 period can be selected. User can extend the WDT overflow period by z z z z z z using prescaler. Interrupt events: (a) External interrupt (PA7~PA0). (b) Internal timer/event counter interrupt (TM1~TM3). (c) ADC end of conversion interrupt I/O port: 16 pins PWM: one channel ADC: max 10(6+4)-bit and 4 channels, at least 10-bit resolution. It can use at converter mode or compare mode Wake-up mode: 1. Port A (PA7~PA0) pin change wakeup 2. i_WDT wakeup Different Package Type: MK7A25PD20C: 20 pin...
