Integrated circuit which disables writing circuitry to memory when the power drops below a power threshold predetermined and controlled by the processor
First Claim
1. An integrated circuit comprising a processor, non-volatile memory, an input for receiving power from a power supply and a power detection unit, wherein the integrated circuit is configured to enable multi-word writes to the non-volatile memory, the processor being configured to:
- control and trim teh amount of power supplied to the input to predetermine a threshold at which operation of the integrated circuit is established; and
the power detection unit being configured to;
monitor a quality of power supplied to the input;
in the event the quality of the power drops below the predetermined threshold, preventing subsequent words in any multi-word write currently being performed from being written to the memory.
