ML610Q400

• Built-in flash memory
Based on Oki Semiconductor's proprietary low-power technology, the ML610Q411/Q412/Q415 operates over a wide voltage range (from 1.1V to 3.6V) at current consumption levels equivalent to that of MCUs based on mask ROM.  The ML610Q411/Q412/Q415 simultaneously enables the use of smaller and lighter batteries because of its low power consumption and adds the advantage of flash memory's short development and time to manufacturing.
 
• Detailed power-management function (ML610Q411/Q412)
The ML610Q411/Q412 includes three power-management functions: HALT mode, STOP mode and dual clock function. The ML610Q411/Q412 keeps power consumption to a minimum even while the CPU is operating through the use of dual clocks.  Users can select a clock frequency of 32.768 kHz or 500 kHz.  Additionally HALT mode will suspend CPU operation entirely but maintain power to the chips peripherals and STOP mode will power down the core and the peripherals.  Low power consumption enables longer battery life and enables the use of smaller batteries, resulting in smaller and lighter devices.  Additionally the ML610Q411/Q412 includes battery management capabilities enabling notification to the end user regarding the need to change the batteries.
 
• Highly efficient RISC-type CPU
The ML610Q411/Q412/Q415 are based on Oki Semiconductor's nX-U8/100 RISC CPU architecture. Over the past 6 years Oki Semiconductor has shipped in excess of 50 million devices based on the nX-U8/100. The CPU offers high performance and low power because it executes most instructions in a single machine cycle with the three-stage pipeline(*2) and has a bit operation instruction, which enables high-speed access to the memory, and a multiplication/division instruction.
 
• LCD driver
ML610Q412 offers 176 dot (44 seg x 4 com) resolution while ML610Q411/Q415 offers 144 dot (36 seg x 4 com) resolution, both include a charge pump circuit.
 
• Two types of A/D converter
The ML610Q411/Q412/Q415 includes two types of A/D converters: a 24-bit RC oscillator and a 12-bit successive approximation.  The high precision ADCs allow direct connection of humidity, pressure and/or temperature sensors.

• Built-in RC oscillator operation (ML610Q415)
The ML610Q415 can operate only with built-in RC oscillator and does not require crystal oscillator, which enables smaller devices.

• On-chip debugging
The ML610Q400 series includes on-chip debugging via Oki Semiconductor's USB based emulator (product name: µEASE). It enables users to debug software programs and erase or write them into the flash memory.
