Microcontroller with RTC drives large LCD displays

19 September 2007 DSP, Micros & Memory

Maxim's new addition to its RISC MAXQ microcontroller product line, the MAXQ3100, is a highly integrated, mixed-signal microcontroller that is ideal for a wide range of data-driven display applications. It includes a digitally trimmable realtime clock (RTC) with a dedicated backup battery pin, an LCD interface that supports up to 160 segments, a frequency-locked loop (FLL), two analog comparators and a digital temperature sensor. The device has 16 KB of EEPROM program memory, 1 KB data SRAM, a watchdog timer, two serial ports (USARTs) and three timers.

The MAXQ3100 is designed for industrial, medical and consumer applications that require an RTC and an LCD controller, such as electricity and flow metering, multimeters, thermostats and temperature data-loggers. The integrated, digitally trimmable RTC enables very accurate time keeping, which is critical for applications that are based on time-of-use (TOU) events such as electricity tariffs. The dedicated RTC battery- mbackup pin lets a battery keep the RTC running when the controller's main power supply is absent. The built-in power management circuit automatically detects and switches the RTC supply back to the main controller power supply whenever it is available. This intelligent power management approach maximises the RTC's battery life. The 160-segment LCD controller allows end equipment to have large, complex displays.

A MAXQ3100 evaluation kit (EV kit) is available that includes an on-board LCD and a JTAG interface board for communication with a PC. Its IDE includes a debugger, assembler/linker, a time-limited version of the IAR C-compiler and a simulator.
