MSP430F1122IDW Technical Specifications

MSP430F1122IDW Key Features

• One 16?bit core for compact code and predictable performance, which improves throughput compared with most 8?bit designs.
• Multiple low?power modes that reduce current draw during idle periods and extend battery life in portable systems.
• On?chip timer and system reset/watchdog functions that simplify reliability and timing design without external components.
• Internal digitally controlled oscillator plus optional crystal support to balance cost, precision, and power across a wide range of applications.

Typical Applications

• Battery?powered telemetry and sensor nodes that require long run time and more than 8?bit performance for local processing and power management.
• Portable instrumentation where low standby current and a single 16?bit core reduce BOM while enabling responsive measurement and control tasks.
• Small industrial controllers that need dependable watchdog reset, deterministic timing and compact package for densely populated PCBs.
• Human?machine interface peripherals that use minimal power in standby and fast wake to service user events and serial interfaces.

MSP430F1122IDW Advantages vs Typical Alternatives

The device offers a clear tradeoff: higher instruction efficiency than 8?bit MCUs and lower active and standby power than many 32?bit options. Its single 16?bit core provides more computational range for control algorithms while keeping silicon and system cost down. On?chip timers, watchdog and simple clock options reduce component count, which makes designs smaller, more reliable and often cheaper to produce than multi?chip solutions.
