• Small 80?pin package offers a balance of I/O count and PCB area for medium?density applications compared with larger QFPs or smaller TSSOPs.
• Multiple low?power modes lower system energy consumption in standby and extend battery life versus always?on designs.
• Generous flash and SRAM (128 KB flash, 8 KB RAM) support larger firmware, more features, and OTA updates when compared to lower?memory microcontrollers.

Typical Applications

• Battery?powered sensor nodes requiring sub?milliamp sleep current, precise 12?bit analog sampling, and multiple serial links for local aggregation and wireless backhaul.
• Industrial control modules where deterministic timers, 12?bit ADC feedback, and a 16?bit CPU deliver tighter closed?loop control and higher reliability over 8?bit alternatives.
• Portable medical instruments that need compact packaging, accurate analog front?ends, and low standby power to extend operating time between charges.
• Consumer and building automation devices that benefit from integrated ADCs, multiple communications interfaces, and moderate flash for feature?rich firmware updates.

MSP430F435IPN Advantages vs Typical Alternatives
