By applying low power modes and FRAM technology this reference design utilizes 1-wire device communication to emulate EEPROM functionality on an MSP430™ microcontroller (MCU). This solution includes the ability to be powered parasitically from the communication line and allocates more memory space than is available than current 1-wire devices on the market.
特性
Complete 1-Wire protocol support assures an easy transition and effortless substitution for similar EEPROM devices
Uses LPMs to accomplish an average standby current consumption of 600 nA in standby mode
Design is achievable on any MSP430 FRAM MCU and allows for flexibility in the available EEPROM memory space
Includes selectable operation modes such as dedicated or parasitic power
Provided firmware may be nodified for use in other 1-wire applications
