Freescale Flexis QE128血压计解决方案

Freescale 公司的Flexis QE128是采用8位HCS08 CPU的微控制器,2.4V时的工作频率高达50.33MHz,2.1V时为40MHz,而1.8V时为20MHz,具有128KB 闪存,25个ADC通路,提供高达25MHz的总线频率.支持多达32个中断/重置源.血压计(BPM)参考设计采用Freescale公司的Flexis MC9S08QE128 MCU, Flexis MCF51QE128, MPR083接近式传感器, MR2A16A异步磁阻RAM, MC9S08JM60 微控制器, MC13202 ZigBee收发器, PXV5050压力传感器和OSRAM 公司的Pictiva OLED 显示器OS128064PK27MY0B00M.本文介绍了Flexis QE128的主要特性和方框图,血压计(BPM)参考设计的主要优势,方框图以及详细的电路图和所用材料清单(BOM).

MC9S08QE128 Series comprised of a pin-compatible 8-bit and 32-bit device duo, is the first family in the Flexis series. The FlexisTM series of controllers is the connection point of the Freescale Controller Continuum, where 8- and 32-bit compatibility becomes reality, delivering the ultimate in migration flexibility.

The S08QE128 pushes the boundaries of the 8-bit architecture performance with 128Kb of Flash, 24 ADC channels and delivering up 25MHz in bus frequency. The 32-bit MCF51QE128 is pin-, peripheral- and tool-compatible with the 8-bit S08QE128 device. They share a common set of peripherals and development tools delivering the ultimate in migration flexibility.
