What are the key features of MSP430G2201IRSA16?
- Ultra-low-power 16-bit MSP430 RISC core with multiple low-power modes enabling coin-cell operation in wireless sensor and remote control designs
- Integrated comparator peripheral for direct threshold detection without an external op-amp, reducing BOM in simple signal monitoring applications
- 16-pin QFN (S-PQCC-N16) package with a compact footprint ideal for space-constrained wearable and IoT edge node designs
What is MSP430G2201IRSA16 used for?
MSP430G2201IRSA16 is suited for ultra-low-power sensor monitoring tasks such as temperature threshold detection, door/window open-closed sensing, and battery-powered remote controls where the MCU spends the vast majority of time in sleep mode. Its integrated comparator allows direct analog threshold comparison without waking the CPU. The small 16-pin QFN form factor fits coin-cell-powered devices with minimal PCB area.

Frequently Asked Questions
How does MSP430G2201IRSA16 achieve ultra-low-power operation for a coin-cell-powered sensor application?
MSP430G2201IRSA16 uses the MSP430 architecture's multiple low-power modes (LPM0 through LPM4) where the CPU and most clocks are halted while the comparator and watchdog timer remain active. In LPM4, supply current drops to the sub-microampere range, allowing a 220 mAh CR2032 coin cell to power the device for several years in a periodic wake-up-and-sense duty cycle of 1 second between measurements.
For a simple temperature threshold alarm, can MSP430G2201IRSA16's comparator replace an external op-amp comparator?
Yes. MSP430G2201IRSA16 integrates a hardware comparator that can compare an external analog input against an internal voltage reference or a resistor-divider-derived threshold. For a temperature alarm using a thermistor, the comparator triggers an interrupt when the thermistor voltage crosses the threshold, waking the CPU from sleep without an external op-amp. This reduces the BOM by at least 1 IC and several passive components.
What clock frequency does MSP430G2201IRSA16 use and how does it affect firmware timing accuracy?
The spec sheet lists a maximum clock frequency of 0.032 MHz (32 kHz) for MSP430G2201IRSA16's low-frequency oscillator mode using the 32.768 kHz ACLK derived from an internal or external crystal. The MSP430G2 value-line devices also include a digitally-controlled oscillator (DCO) capable of running at higher frequencies (up to 16 MHz on similar MSP430G2 parts), but the nominal rating here reflects the low-power 32 kHz crystal mode used for timekeeping in sleep-dominant applications.
What packaging and RoHS status should be confirmed before selecting MSP430G2201IRSA16 for a new production design?
MSP430G2201IRSA16 comes in a 16-pin QFN package (JEDEC code S-PQCC-N16) with a small, leadless footprint requiring reflow soldering. The Pb-free code is listed as 'No', indicating this specific ordering code uses tin-lead (SnPb) solder finish rather than a lead-free alternative — designers subject to RoHS Directive must verify this and select a lead-free variant if required. YTEOL is 0, so end-of-life planning should be confirmed with the distributor.
