The MAXQ2000 microcontroller is a low-power, 16-bit device that incorporates a liquid-crystal display (LCD) interface that can drive up to 100 (-RBX/-RBX+) or 132 (-RAX/-RAX+/-RFX/-RFX+) segments. The MAXQ2000 is uniquely suited for the blood-glucose monitoring market, but can be used in any application that requires high performance and low-power operation. The device can operate at a maximum of either 14MHz (VDD
> 1.8V) or 20MHz (VDD
> 2.25V). The MAXQ2000 has 32kWords of flash memory, 1kWord of RAM, three 16-bit timers, and one or two universal synchronous/asynchronous receiver/transmitters (UARTs). Flash memory aids prototyping and low-volume production. The microcontroller core is powered by a 1.8V supply, with a separate I/O supply for optimum flexibility. An ultra-low-power sleep mode makes these parts ideal for battery-powered, portable equipment.
