Maxim MAXQ610和MAX7032水表自动读表(AMR)参考设计

Maxim公司的水表自动读表(AMR)参考设计LFRD003采用带红外模块的MAXQ610低功耗16位MAXQ微控制器和MAX7032基于晶振的分数N收发器,提供了使用工业/科学/医疗射频(ISM-RF)的完整平台,可以实现水表AMR的设计.本文介绍了MAXQ610和MAX7032主要特性, 水表自动读表(AMR)参考设计主要特性以及RF模块与手持接口 (HHI)部分电路图,相应的材料清单和PCB布局图.

The MAXQ610 is a low-power, 16-bit MAXQ® microcontroller designed for low-power applications including universal remote controls, consumer electronics, and white goods. The MAXQ610 combines a powerful 16-bit RISC microcontroller and integrated peripherals including two USARTs and an SPI™ master/slave communications port, along with an IR module with carrier frequency generation and flexible port I/O capable of multiplexed keypad control.

The MAXQ610 includes 64KB of flash memory and 2KB of data SRAM. Intellectual property (IP) protection is provided by a secure MMU that supports multiple application privilege levels and protects code against copying and reverse engineering. Privilege levels enable vendors to provide libraries and applications to execute on the MAXQ610, while limiting access to only data and code allowed by their privilege level.
