Ultra-Low-Power Mixed-Signal, 16-Bit Microcontroller Extends Battery Life in Power-Sensitive Applications
Note to Editor:
- The MAXQ2010 16-bit microcontroller provides a power-saving stop mode, which causes the device to consume less than 400nA (typ) to extend the life of battery-powered devices.
- For additional power savings, in active mode the MAXQ2010 consumes only 3.1mA at 10MHz operation.
- An integrated 12-bit ADC allows readings to be taken from up to eight single-ended channels or four differential channel pairs at up to 312ksps.
- An internal regulator allows operation from a single lithium coin cell battery.
- The MAXQ2010 is ideal for battery-powered data acquisition systems and equipment that wakes up every few minutes to take measurements like many types of sensors or an environmental data-logger.

SUNNYVALE, CA—November 20, 2008—Maxim Integrated Products (NASDAQ: MXIM) introduces the MAXQ2010, a 16-bit mixed-signal microcontroller with an unique power-saving stop mode. Stop mode reduces power consumption to 370nA typical and 6.5µA maximum at +85°C, thus extending the life of battery-powered devices. Designed on a RISC architecture, the MAXQ2010 balances high-speed execution (up to 10 MIPS at 10MHz) and data sampling (up to 312ksps ADC conversion at 12 bits) with a low-power active-mode current (3.1mA, typical, at 10MHz). An integrated regulator allows direct operation from a single lithium coin cell at 2.7V to 3.6V.
With its many integrated analog and digital capabilities and its multiple power-saving modes, the MAXQ2010 is an optimized single-chip solution for battery-powered data acquisition applications. The device's low-power stop mode makes it especially valuable in equipment that spends the majority of its life inactive, only waking up once every few minutes to take measurements. Typical examples include many types of sensors, data acquisition systems, or environmental data-loggers.
Unmatched Power Control and Savings
The MAXQ2010 offers multiple power-saving operating modes. A key feature of the device is its industry-leading stop mode, which allows the microcontroller to reduce power consumption to less than 400nA (typ) by halting code execution. Depending on the needs of the application, the integrated LCD controller and real time clock (RTC) can optionally remain active during stop mode.
For additional power savings, the MAXQ2010 consumes only 3.1mA (typical) at 10MHz operation in active mode.
Integrated Analog Features Enable Data Acquisition
The MAXQ2010 includes a 12-bit ADC capable of data conversion at up to 312ksps. Samples are taken from up to eight analog inputs which can be selected as single-ended inputs and/or differential input pairs. The ADC includes a 1.5V ±2% voltage reference and can be configured to automatically capture and buffer sequences of up to 16 samples without processor intervention.
Broad Feature Set Optimized for Battery-Powered Applications
The MAXQ2010 provides additional features critical for portable, battery-powered applications. For a user interface, an integrated LCD controller can drive up to 160 segments directly in a ¼-muxed configuration. A supply-voltage monitor measures the power supply against a programmable threshold from 2.7V to 3.5V in 0.1V increments, enabling an application to detect low power and notify the user to replace the battery.
To further reduce system costs, the MAXQ2010 uses a low-cost 32kHz crystal to generate the 8.389MHz system clock and enable the real-time clock (RTC) peripheral. The RTC provides programmable subsecond and time-of-day alarms, which can be used to wake up the microcontroller from stop mode to perform functions at programmable time intervals.
Development Tools Accelerate Design
For rapid application development, a MAXQ2010 evaluation (EV) kit is available. Providing both the microcontroller evaluation platform and all necessary software, the kit seamlessly connects the microcontroller's onboard bootloader and debugging features with PC-side software to communicate with an integrated development environment. Options for application development include a free assembly project development environment (MAX-IDE), Rowley Crossworks IDE, and IAR Embedded Workbench® for MAXQ® (available in time-limited or code-limited versions for free product evaluation). An integrated JTAG-compatible debug port on the MAXQ2010 provides hardware-based in-circuit debugging and programming support for both C and assembly-based applications.
The MAXQ2010 is packaged in a 100-pin LQFP and operates over the -40°C to +85°C temperature range. Prices start at $2.95 (10,000-up, FOB USA). For more information please visit: www.maxim-ic.com/MAXQ2010-Micro.
