EVALUATION KIT AVAILABLE  
MAX71617/MAX71637  
Energy Measurement SoCs  
● ARM Cortex-M3 Features  
General Description  
• 1MB Flash  
The MAX71617 is a low-power, single-phase energy mea-  
surement system-on-chip (SoC), and the MAX71637 is a  
low-power polyphase energy measurement SoC. Based  
on an ARM Cortex®-M3 core, the devices can run modern  
operating systems that monitor and report energy usage  
and implement communications stacks. In addition to the  
main administrative core, the devices include a MAXQ30  
CPU core to perform metering functions and a discrete  
compute engine for the DSP related tasks necessary for  
accurate energy monitoring and measurement, last cycle  
analysis, and FFT functions to compute the frequency  
spectra of the selected channel.  
• 64KB Code RAM  
• 64KB System RAM  
• Six UART Channels  
• Seven Timer Channels  
2
• I C Master/Slave Peripheral  
• Three SPI Peripherals  
• Smart Card Interface  
● MAXQ30 Features  
• 64KB Program RAM  
• 8KB Data RAM  
• 16KB Page RAM  
The DSP core provides the following energy and power  
measurement features in registers:  
• Four Meter Pulse Outputs (Configurable)  
2
• Two I C Master/Slave Peripherals  
• SPI Master/Slave Peripheral  
• 50-Segment,ꢀ6-CommonꢀLCDꢀInterface
