MSP430F1122IPW Key Features
- Single 16-bit RISC core delivers compact code and efficient execution for control tasks.
- Low-voltage operation (1.8?C3.6 V) enables direct connection to common battery chemistries and low-power rails.
- Integrated Timer_A provides precise PWM, input capture and interval timing for motor control and power management.
- On-chip serial interface offers simple UART-compatible communications to connect sensors and modules with minimal external components.
- Multiple low-power modes reduce system current in idle states, extending battery life in portable and remote applications.
- 20-pin TSSOP package conserves PCB space while still exposing a practical number of GPIOs and peripheral pins.
Typical Applications
- Battery-powered sensor nodes that require long standby life and periodic data transmission using a low-power 16-bit MCU and UART link.
- Handheld instruments where compact 20-pin packaging and multiple low-power modes extend battery runtime and reduce product size.
- Simple motor or LED control systems that use Timer_A PWM and capture functions for accurate pulse-width control and feedback tasks.
- Industrial monitoring modules where 1.8?C3.6 V operation and industrial temperature tolerance support rugged field deployment.
MSP430F1122IPW Advantages vs Typical Alternatives
The device stands out against 8-bit microcontrollers by offering a 16-bit RISC architecture for more efficient arithmetic and tighter code density. Compared with larger MCUs, it consumes less power in active and sleep states, making it ideal where energy is constrained. The 20-pin TSSOP package provides a smaller footprint than many 28-pin or larger parts while still delivering timers and serial I/O. These traits translate to lower system cost, fewer external components, and longer battery life in many embedded designs.
