MA015 Datasheet
Version 2.00
1 Features
 Single Chip 8-bit CPU
 Memory
 ROM (shared by program and data) : 128K Bytes
 Data RAM : 320 Bytes
 Operating voltage: 1.8V to 3.6V
 31 input/output pins with 15 input pins with wake-up function.
 Port 0 and Port 3 I/O pins with input wake-up function.
 Ports 1.3, P1.6 and P1.7 are multi-function with Timer 0, Timer 1 and Timer 2 carry out.
 Port 3.6 can be clock source of timer.
 Two power-down modes for saving power consumption:
 Halt mode: micro-controller no operation (main- oscillator still oscillating)
 Stop mode: micro-controller no operation (all oscillators stop oscillating)
 Three re-loadable 16-bit countdown timers with interrupt function.
 Build-in watchdog timer
 Build-in low voltage detector (2.2V), low voltage reset (typical voltage: 1.8V)
 Oscillator
 Single clock
 Main oscillator operation at crystal or RC mode is selected by mask option
 Crystal/Ceramic oscillator up to 4MHz @ 1.8V
