Intelligent System State Restoration after Power Failure with Compute Through Power Loss Utility
Description
Compute Through Power Loss (CTPL) is a software utility for ultra-low-power MSP430FRxx FRAM microcontrollers that enables an application to easily save the CPU and peripheral states into non-volatile FRAM, before powering down or entering a deep-sleep mode like LPMx.5. CTPL then automatically restores the application where the application last executed (this is also referred to as context-save and restore). This TI design showcases how one can easily integrate the utility library to be used in their application. CTPL can enable a faster wake-up time from cold-start by bypassing the startup routine which can be cycle intensive.
Features
• Uses Compute Through Power Loss (CTPL) software utility
• Complete shutdown with software state retention via VCC monitoring
• Ease-of-use with low-power modes LPMx.5
• Ideal for energy harvesting applications
