Product details
Overview
MSP430F5435IPN from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 192 KB flash, 16 KB RAM, 12-bit ADC (14 external + 2 internal channels), three 16-bit timers (TA0/TA1/TB0), four USCI modules (2 UART/IrDA/SPI + 2 I²C/SPI), and RTC functionality - deployed in battery-powered sensor systems and digital timers requiring sub-µA standby current.
For engineers reviewing the MSP430F5435IPN datasheet, MSP430F5435IPN pinout, MSP430F5435IPN application, or MSP430F5435IPN equivalent, key selection criteria include LPM3 current (2.6 µA), 80-pin LQFP package compatibility, dual USCI_A/B interface count, 18-MHz max system clock, and integrated LDO core regulation - all confirmed for this exact PN-package variant.
Technical Context
The MSP430F5435IPN implements a unified clock system (UCS) with FLL stabilization, VLO/REFO internal sources, and support for 32-kHz crystals and up to 32-MHz high-frequency crystals. Its CPUXV2 core executes instructions in single-cycle mode with constant generators for optimized code density.
Power management includes programmable LDO output voltage, supply voltage supervision (SVS), brownout reset (BOR), and five low-power modes (LPM0–LPM4). Wake-up from LPM3 occurs in under 5 µs via RTC, GPIO, or timer events - critical for responsive energy harvesting nodes.

FAQ
What is the maximum operating frequency of the MSP430F5435IPN?
The MSP430F5435IPN supports a maximum system clock frequency of 18 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This frequency is validated across the full operating voltage range (2.2 V to 3.6 V) and enables real-time execution of control loops and sensor processing without compromising ultra-low-power operation in active mode.
Does the MSP430F5435IPN include an integrated real-time clock (RTC)?
Yes, the MSP430F5435IPN integrates the RTC_A module with calendar mode, alarm capability, and crystal oscillator support (32.768 kHz). It operates fully in LPM3 with only 2.6 µA current draw, retaining full RAM and maintaining time accuracy - making it ideal for time-stamped sensor logging and scheduled wake-up in battery-powered devices.
How many analog input channels does the MSP430F5435IPN ADC support?
The MSP430F5435IPN features a 12-bit ADC12_A module with 14 external analog input channels (A0–A15, excluding A10/A11) and 2 internal channels (temperature sensor and VCC/2). All channels are accessible through dedicated pins in the 80-pin LQFP package, and the autoscan function enables automatic sequential conversion without CPU intervention.
Is the MSP430F5435IPN pin-compatible with other devices in the MSP430F54xx family?
Yes, the MSP430F5435IPN shares identical pinout and electrical characteristics with MSP430F5437IPN and MSP430F5418IPN in the 80-pin PN package. This allows direct substitution within the same PCB layout, provided firmware accommodates differences in flash size (192 KB vs. 256 KB or 128 KB) and peripheral enablement.
What power supply configurations does the MSP430F5435IPN support?
The MSP430F5435IPN supports dual power domains: AVCC/AVSS for analog circuitry (ADC, reference, crystal oscillator) and DVCC/DVSS for digital logic. It includes an integrated LDO regulator that generates VCORE from DVCC, programmable from 1.8 V to 2.2 V - enabling dynamic voltage scaling to minimize active-mode power consumption based on required performance.
