MSP430 Offers the Lowest Power Active Mode and Sleep Modes
MSP430 is the lowest power microcontroller family, offering 200+ Ultra-Low Power devices. Browse through our scalable portfolio using the MCU Selection Tool!
MSP430 offers microcontrollers with:
- The lowest power active and sleep modes with Brown Out Reset (BOR).
- <1µs wakeup from sleep mode (Our Low Power Mode 3 includes RAM retention, self wakeup, and BOR at 0.7µA @ 3V)

| Device | Active @ 3V w/BOR (µA) | Standby w/Self wakeup and BOR (µA) |
| MSP430F2001 | 300 µA | 0.6 µA |
| MSP430F2619 | 515 µA | 0.6 µA |
| STM8L151G4 | 702.8 µA | 5.8 µA |
| PIC24F16KA102 | 1110 µA | 0.85 µA |
Brown Out Reset (BOR)
The Brown Out Reset (BOR) circuit detects low supply voltages and resets the device by triggering a POR signal when power is applied or removed. This protects your design and prevents erratic behavior. MSP430’s zero-power BOR circuit is continuously turned on, including in all low power modes.
Watchdog Timer (WDT)
The MSP430’s Watchdog Timer (WDT) has several functions. One configuration is setting the WDT as an interval timer to generate interrupts at selected time intervals (allowing the MSP430 to wakeup from low power modes). Alternatively, it may perform a controlled system restart after a software problem occurs.

MSP430 Offers 20+ Years in Battery Life
Using an ideal 3V CR2032 Coin Cell Battery rated at 200mAh, the MSP430 offers the longest possible battery life.
The MSP430 Can Wake Up from Low Power Modes in <1µs
The MSP430's Digitally Controlled Oscillator (DCO) provides wakeup times that are less than 1 microsecond. This means your application stays in sleep mode longer, and less time and power are wasted during wakeup. Competing devices require more time during wakeup, which results in higher average current consumption leading to weaker battery-powered performance.

Minimal Average Current Consumption » Longer Battery Life
Using a standard 3V CR2032 Coin Cell Battery rated at 200mAh, the MSP430 offers the longest possible battery life.

| Active Mode w/ BOR, 3V Operation, operating from Flash | 300uA | 515uA | Estimated using ratio of Active Current, Idle Current, and Internal FRC current+LPBOR = 1110uA | Supply Current in Run Mode running off Flash (700uA) + BOR (2.8uA) = 702.8 uA |
| Standby Mode w/ WDT, RAM retention, BOR, 3V Operation | LPM3 w/VLO (includes BOR & WDT) = 0.6uA | LPM3 w/VLO (includes BOR & WDT) = 0.6uA | Power Down Base Current (.105) + WDT (.87) + LPBOR (.095) = 1.07uA @ 3.3V =0.856uA @3V Use 0.8 multiplier to convert to 3V | Low Power Wait Mode (3uA) + BOR (2.8uA) + Independent Watchdog (TBD) = >5.8uA |

Procedure for Calculating Average Current Consumption vs. Duty Cycle (% in Active Mode): Average Current Consumption = Active Current * (% in Active) + Standby Current * (% in Standby) (The values used for Active Mode and Standby Mode are based on the table above.) Procedure for determining Battery Life Comparison: Average Current Consumption = Active Current * (% in Active) + Standby Current * (% in Standby). For the first example, we used 1% Active, and 99% Standby - This is typical for many portable measurement systems. For the second example, we used 0.1% Active, and 99.9% Standby - This is typical for many wireless sensor network applications. Once Average Current Consumption is determined, we can find estimated battery life with the following equation (In our example, we used a CR2032 coin cell battery rated for 200mAh): Estimated Battery Life in hours= 200mAh/(Average Current Consumption). Estimated Battery Life in years = (Estimated Battery Life in hours) / (365days/year * 24hours/day).
