      Low Power Consumption ML62Q2000 Series / ML62Q2500 Group (U16)


      ML62Q2500 series System Block Diagram

      The ML62Q2500 group CMOS MCUs utilize LAPIS TECHNOLOGY™ 's original 16-bit RISC U16 Core to achieve superior performance.
      This group is equipped with program memory(Flash memory), data memory(RAM), data Flash (Erase unit:128byte, Write unit:1byte), and rich peripheral functions such as the multiplier/divider, CRC generator, Clock generator, Timer, General Purpose Ports, UART, Synchronous serial port, I2C bus interface unit(Master, Slave),
      Voltage Level Supervisor(VLS), High-speed Successive approximation type 12bit A/D converter, Safety function (IEC60730/60335 Class B), and so on.
      The built-in on-chip debug function enables debugging and programming the software. Also, the ISP (In-System Programming) function supports the Flash programming in the production line.
      The ML62Q2500 group uses a small WQFN package to reduce the mounting area of the MCU and enables miniaturization of the set.

      Product Features

      Feature 1Class-leading*1 low power consumption (0.6μA @ "HALT-D" mode)

      HALT-D mode

      The ML62Q2000 series has a new "HALT-D" mode that stops the CPU, high-speed clock, and some peripheral circuits.
      As a result, the class-leading 0.6μA has been achieved in the state which operates timers using the built-in RC oscillation circuit.
