8-bit Microcontroller
FEDL610Q485-01
Issue Date Aug. 25, 2014
GENERAL DESCRIPTION
This LSI is a high performance CMOS 8-bit microcontroller equipped with an 8-bit CPU nX-U8/100 and integrated with
peripheral functions such as synchronous serial port, UART, melody driver, and Analog compartor.
The CPU nX-U8/100 is capable of efficient instruction execution in 1-intruction 1-clock mode by 3-stage pipe line architecture
parallel processing. Additionally, it adopts the low-/high-speed dual clock system, standby mode, and process that prohibits
leak current at high temperatures, and is most suitable for battery-driven applications.
MTP version can rewrite programs on-board, which can contribute to reduction in product development TAT. The flash
memory incorporated into this MTP version implements the mask ROM-equivalent low-voltage operation (1.25V or higher)
and low-power consumption (typically 5uA at low-speed operation), enabling volume production by the MTP version. For
industrial use, ML610Q485P with the extended operating ambient temperature ranging from -40°C to 85°C are available.
