Overview


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.

Feature3 : 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

This system enables selection of low-speed and high-speed clocks for each CPU and peripheral circuit. For example, when the high-speed clock is selected for the CPU and timer operation, the UART is workable at low-speed clock to wait for a receive even if the high-speed needs to be stopped. This provides flexible clock management that can help reduce power consumption considerably.

 

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.

Features


Features1
Take over the noise resistance of "Tough" MCUs
  • This new series take over the noise resistance of LAPIS Semiconductor's 'Tough' series of MCUs (ML620150, ML620130), which have been proven in noise testing to be superior compared with competitor MCUs.

Features2
Enhanced safety functions
  • 8 new functions have been added to the existing safety functions of 'Tough' MCUs (ML620130).
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
  • I2C self-test
  • WDT test
  • Clock backup
  • MCU temperature monitoring
Features3
Crystal 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)
Features4
Prevents 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.
 

Applications


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.
