ML620Q131/2/3/4/5/6

16-bit micro controller

1/33

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

· CPU

- 16-bit RISC CPU (CPU name: nX-U16/100)

- Instruction system: 16-bit length instruction

‒ Instruction set: Transfer, arithmetic operations, comparison, logic operations, multiplication/division, bit manipulations,

bit logic operations, jump, conditional jump, call return stack manipulations, arithmetic shift, and so on

‒ On-chip debug function built in

· Interrupt controller

- Non-maskable interrupt source: 2 (Internal sources: BACK-UP CLOCK, WDT)

- Maskable interrupt sources: 30 (Internal sources: 25, External sources: 5)

- 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)
