MAXQ2000开发板套件编程器的评估板-嵌入式-MCUDSP规格书PDF中文资料

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 market, but can be used in any application that requires high performance and low-power operation
