MSP430F2122TRTVT Technical Specifications

MSP430F2122TRTVT Key Features

• 16-bit RISC core with efficient instruction set for compact code and faster interrupt response.
• Ultra-low-power operation with multiple low-power modes, extending battery life in portable systems.
• On-chip nonvolatile memory (2 KB flash) that reduces BOM cost by eliminating external program memory.
• Integrated USI serial interface provides SPI and I2C connectivity, simplifying sensor and peripheral integration.

Typical Applications

• Battery-powered sensor nodes needing long standby time and simple local processing with low quiescent current.
• Small motor-control or actuator interfaces requiring deterministic timer capture/compare and compact firmware.
• Serially connected modules such as I2C sensors or SPI peripherals where on-chip USI reduces external logic.
• Cost-sensitive consumer control panels or handheld devices that demand minimal PCB footprint and low system cost.

MSP430F2122TRTVT Advantages vs Typical Alternatives

The device excels where low active and standby power matter most. Compared with larger microcontrollers, it delivers comparable control capabilities while using a smaller footprint and less memory overhead. Its integrated USI and timer peripherals often replace discrete interface chips, cutting component count and board area. The 16-bit core gives more arithmetic headroom than 8-bit alternatives and typically achieves similar performance at lower clock rates, which helps conserve energy in continuous or interrupt-driven tasks.
