Maxim Integral Products and services introduces the MAXQ2010, a 16bit mixed- signal microcontroller with an original power-saving stop mode. Stop mode reduces power consumption to 370 nA t ypi cal and 6. 5 µA maxi mum at +85°C, t hus ext ending t that he life of battery-powered devices. Designed on a RISC architecture, the MAXQ2010 balances high speed execution (up to 10 MIPS at 10 MHz) and data sampling (up t o 312 ksps ADC conversion at 12 bits) with a low-power active-mode current (3. 1 mA, typical, at 10 MHz).
A built-in regulator allows direct operation from the single lithium coin cell at – 7 V to 3. 6 V. Having its many integral analogue and digital capabilities and its particular multiple power-saving modes, the MAXQ2010 is definitely an optimised single-chip solution for battery-powered data acquisition applications. The device’s low-power stop mode causes it to be specially valuable in equipment that spends the major- ity of its life inactive, only getting out of bed once every couple of minutes to simply take measurements. Typical these include various types of sensors, data acquisition systems, or environmental data-loggers. The MAXQ2010 offers multiple power-saving operating modes.
A vital feature of the unit is its industry-leading stop mode, allowing the microcontroller to cut back power consumption to notably less than 400 nA (typ. ) by halting code execution. With respect to the needs of the applying, the integral LCD controller and realtime clock (RTC) can optionally remain active all through stop mode. For additional power savings, the MAXQ2010 consumes only 3. 1mA (typical) at 10 MHz operation in active mode. The MAXQ2010 provides additional features important for portable, battery-powered applications.
For a graphical user interface, a built-in LCD controller can drive as much as 160 segments directly in a 1 configuration. A supply-voltage monitor measures the ability supply against a programmable threshold from – 7 V to 3. 5 V in 0. 1 V increments, enabling a software to detect low power and notify the consumer to restore the battery. For rapid application development, a MAXQ2010 evaluation (EV) kit can be obtained.
