FRAM controllere revolutionerer context 'save and restore''
Texas Instruments introducerer ny teknologi i MSP430 microcontrollere, der sikrer, at det ikke kan forekomme datatab i forbindelse med power-afbrydelser (in english).
Overcoming a design hurdle that has burdened engineers for decades, Texas Instruments (TI) has announced a revolutionary Compute Through Power Loss (CTPL) technology to enable context save and restore across its MSP430 FRAM microcontroller (MCU) family, including the new MSP430FR6972 MCU.This patent-pending technology enables instantaneous wakeup with intelligent system-state restoration after an application unexpectedly loses power. In addition, the new MSP430FR6972 MCU with TI's CTPL technology includes integrated smart analog and digital peripherals to reduce system cost, power and size. These features include a low-power segment LCD controller, a 12-bit differential analog-to-digital converter (ADC) with internal window comparator, and a 256-bit AES accelerator.
The ultra-low-power MSP430FR6972 MCU with 64 KB of non-volatile FRAM highlight TI's leading ULPBench scores for 16-bit MCUs and can be used for data logging to enable applications such as a wireless motor condition monitor. This system was developed as a TI Design in Kilby Labs, TI's center for innovation research, and is paired with TI's bq25570 energy harvesting IC and SimpleLink multi-standard CC2650 wireless MCU to operate from a coin cell battery for decades. This system monitors and analyzes motor vibration frequencies and allows operators to accurately predict and schedule maintenance, reducing potential for machine failures.
The unique ultra-low-power capabilities of non-volatile FRAM-based MCUs includes:
- Reduces manufacturing costs by decreasing programming times on an assembly line.
- Unified FRAM allows flexible memory use across data and application code - a very flexible solution for updates in the field.
- Unbeatable write speeds, combined with 10 billion times more write-cycle endurance compared to traditional non-volatile memory solution - excellent for data-logging applications.
- Further simplifies code development because it does not require pre-erasure of segments and can be accessed at the bit-level, enabling constant on-the-fly data logging with zero extra power.
