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 ROM size: 2K x 16 bits
z RAM: 37 x 8 bits(Special Purpose Register)
+ 128 x 8 (General Purpose Register)
z STACK: 8 Levels
z One instruction build by two systems clock.
z 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
using prescaler.
z Interrupt events:
(a) External interrupt (PA7~PA0).
(b) Internal timer/event counter interrupt
(TM1~TM3).
(c) ADC end of conversion interrupt
z I/O port: 16 pins
z PWM: one channel
z ADC: max 10(6+4)-bit and 4 channels, at least
10-bit resolution. It can use at converter mode
or compare mode
z Wake-up mode:
1. Port A (PA7~PA0) pin change wakeup
2. i_WDT wakeup
z Different Package Type:
MK7A25PD20C: 20 pin DIP
MK7A25PS20C: 20 pin SOP
MK7A25PD18C: 18 pin DIP
MK7A25PS18C: 18 pin SOP
MK7A25PD14C: 14 pin DIP
MK7A25PS14C: 14 pin SOP

6. Function Descriptions
This device provide many functions that are Timer, WDT, PWM, ADC, Capture, Interrupt, Table location, Reset,
Program Counter and STATUS register. We would like to describe in detail.
6.1 I/O Port
There are 3 I/O ports to input or output data, each port has different function. The port A can be external
interrupt, EXT_CLK clock input or capture input by register option. The port B can be analog input of ADC
function. The port C can be external RC oscillator input, system reset input (reset function) or output of PWM
function.
6.1.1 Port A
There are 3 registers to set the 8 I/O ports which are PA_DIR, PA_DAT, PA_PLU. Each pin of Port A can be
external interrupt input or normal I/O. To know how to set these pins as external interrupt, please refer to
Chapter 6.7. Pin PA4 has multiple functions. User should define it at Configure Register bit 8 at first.
