LAPIS Semiconductor (San Jose, CA), a ROHM Group Company, recently introduced the ML610Q100 series of low-cost, low-power microcontrollers. The Mini LP Micros’ peripherals around the processing core and non-volatile memory and RAM include: GPIO, PWMs, counter/timer blocks, ADCs and comparators. The devices exhibit very low power consumption in both sleep (1uA typical) and operating modes (3.7mA typical), while executing one instruction per clock cycle at up to 8 MHz clock rates. The microcontrollers are unique in having their timing reference circuit completely integrated within the devices, meaning no external crystal or any other component is required. Some of the devices in the Mini LP Micro series have internal writable Flash RAM, which eliminates the need for external EEPROM for data storage. Their wide supply voltage range (2.7V dc to 5.5Vdc) and temperature range (-40°C to 85°C) allow the Mini LP Micros to be used in battery-powered and energy-harvesting applications located in harsh environments.
