ML610Q4xx / ML6104xx System Block Diagram
  • The ML610Q4xx of high-performance CMOS microcontrollers integrate LAPIS Technology's original 8bit U8 Core CPU, enabling high efficiency instruction execution (1 instruction/clock) through parallel processing based on a 3-stage pipeline architecture. The clock generator circuit uses a dual clock configuration and features both low-speed mode and low power mode operation.

  • The ML610Q4xx, which has proven popular in the portable battery-driven and handheld device markets, leverages proprietary low-power technology and incorporates Flash memory capable of operation at only 1V along with optimized power management functions and a high efficiency RISC CPU to minimize power consumption. In addition, a built-in LCD driver, 2 ADC circuits, on-chip debugger function, and other peripheral circuits make these MCUs ideal for portable LCD-equipped devices such as smart watches, activity/heart rate monitors, and thermostats.
    Furthermore, rewritable Flash memory shortens development and production times, while low current consumption and multiple peripheral functions help to reduce size and weight.
    Also, an expanded temperature range (-40°C to +85°C) enables suitability with industrial equipment such as data loggers used for temperature processing for food and other products.
