Normal type ML62Q1800 Group 16bit MCUs (Industrial Grade)
The ML62Q1000 series has a wide lineup of ROM capacities and package sizes that take into account common designs and scalability for system optimization.
Therefore, even if the number of terminals and ROM capacity need to be changed, the software assets can be reused, making it ideal as a "platform" for model development.

16bit ML62Q1000 series
- Feature 1: Multiple peripherals
A wide array of peripheral circuits are built-in, including numerous serial communication circuits, multifunction timers, a high accuracy analog function, and flash memory that supports background operation allows executing the program code while writing to the data flash.
- Feature 2: Broad lineup
The broad lineup includes several package types, from 16 to 64 pins, in program memory sizes ranging from 16KB to 64kB. Software-compatible peripheral functions are built in. The similar pin layouts enables flexible changes of package and/or program size.
- Feature 3: Safe operation
Some circuits are added to expand the self-test range. Also, the mcu provides functions that prevent crystal oscillation stop by pin leakages or malfunctions at power up and/or at low voltage.
Complete dual clock system drivers low power consumption
Complete Dual Clock System
Current Control at Powerup
Controlling the initial current at the power up and utilizing a low-speed clock as an initial clock minimizes the startup current, allows the operation with a current-limited power supply.
Feature 1Strong against noise and compatible with high temperatures
Cleared the highest class (±8kV)
during IEC61000-4-2 ESD noise testing (also cleared ±30kV)
Broad operating temperature range: -40°C to +105°C Compatible with high temperatures.

Feature 2Enhanced safety functions
- Conventional safety functions
- RAM parity error
- RAM guard
- SFR guard
- Invalid memory access
- Oscillation frequency test
- A/D converter self-test
- NEW！Safety functions
- Flash memory CRC calculation
- GPIO self-test
- UART self-test
- SSIO self-test
- WDT test
- Clock backup
8 new functions have been added to the existing safety functions of 'Tough' MCUs (ML62013x series).
Feature 3Crystal oscillator strong against leakage (Less incidence of oscillation stop ! Safe in case it's stopped !)
Adopting a crystal oscillator circuit strong against leakage, prevents oscillator stop due to moisture adhesion. Also, the backup RC oscillator prevents system freeze even in case the oscillation happends to stop (48-pin to 100-pin products)
Feature 4Prevents malfunctions during power up (Prevents overcurrent, FET damage, and DAC noise)
The voltage detection reset function works at power up or at a low voltage to prevent problems caused by undefined or open output condition of ports.
High functionality, High performance and Low power tough MCU "ML62Q1000 series" which is built-in "U16 Core" can use it for the various uses such as consumer electronics, industrial equipment by taking over the noise resistance of "Tough" MCUs and adding to the enhanced safety functions.
Especially the safety functions realize not only fault diagnosis of peripheral equipment but self-diagnosis of MCUs. Therefore ML62Q1000 series are suitable for the high functional home appliance and compact appliance for kitchen.
ML62Q1000'ｓsafety functions (IEC/UL 60730 class B compliant)
One thing to pay special attention to in designing electrical home appliances is to prevent accidents in advance. Recently, microcontrollers are used for electric home appliances, and safety is secured by the function of microcontroller. Therefore, in order to avoid danger, the microcontroller itself needs a safety function to diagnose the failure of the microcontroller itself.
The ML62Q1000 series has many safety functions as hardware.
