General Description
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 mar-
ket, 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/asyn-
chronous 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 bat-
tery-powered, portable equipment.
