ML620Q131B/2B/3B/4B/5B/6B
16-bit micro controller
GENERAL DESCRIPTION
This LSI is a high performance CMOS 16-bit microcontroller equipped with an 16-bit CPU nX-U16/100 and integrated with rich
peripheral functions such as the timer, PWM, comparator, voltage level supervisor, UART, I2C, and successive approximation
type A/D converter.
The CPU nX-U16/100 is capable of efficient instruction execution in 1-intruction 1-clock mode by 3-stage pipeline architecture
parallel processing. It has the data flash memory area which can be written by software.
In addition, the on-chip debug function that is installed enables software debugging and programming.
FEATURES

− Four interrupt levels and masking function
• Time base counter
− Low-speed time base counter × 1 channel
• Watchdog timer
‒ Non-maskable interrupt and reset
(The first overflow generates an interrupt, and the second overflow generates a reset)
‒ Free running
‒ Overflow period: 4 types selectable (125 ms, 500 ms, 2 s, and 8 s at 32.768 kHz)
