Product details
Overview
MSP430F4361IPNR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller with 24KB+256B flash, 1KB RAM, integrated 160-segment LCD driver, dual 16-bit timers (Timer_A3 and Timer_B3), and USART0 supporting UART/SPI modes. It operates from 1.8 V to 3.6 V and targets battery-powered portable instrumentation and LCD-based metering systems.
For engineers reviewing the MSP430F4361IPNR datasheet, MSP430F4361IPNR pinout, MSP430F4361IPNR application, or MSP430F4361IPNR equivalent, key selection considerations include its 80-pin QFP package, absence of ADC12 module (per F43x1 family designation), wake-up time under 6 µs from standby, and LCD segment drive capability up to 160 segments with four common outputs.
Technical Context
The MSP430F4361IPNR implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling sub-6-µs wake-up from standby mode. Its peripheral set includes Timer_A3 (three capture/compare registers), Timer_B3 (three capture/compare registers with shadow registers), and one USART (USART0) configurable as asynchronous UART or synchronous SPI.
It integrates an on-chip comparator, supply voltage supervisor with programmable level detection, brownout detector, and LCD controller supporting static to 4-mux configurations. The device excludes the ADC12 module-confirmed by the "F43x1" suffix and functional block diagram-distinguishing it from non-"1" variants like MSP430F436IPN.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F436IPN | Includes ADC12 module (12-bit, 8-channel); same flash/RAM, package, and peripherals otherwise. | Suitable where analog sensor digitization is required on-chip; not drop-in due to ADC12 pin assignments and register map differences. | Select MSP430F436IPN only if integrated ADC functionality is needed; MSP430F4361IPNR avoids ADC-related power and layout complexity. |
| MSP430F4351IPN | 16KB+256B flash, 512B RAM; identical peripheral set and no ADC12; shares same 80-pin QFP footprint. | Better suited for cost-sensitive or memory-constrained designs where 24KB flash is unnecessary. | MSP430F4351IPN offers pin-compatible alternative with reduced memory; verify code size fits within 16KB before substitution. |
Compared with MSP430F436IPN, the MSP430F4361IPNR removes ADC12 to reduce dynamic power and simplify analog design, while compared with MSP430F4351IPN it provides +8KB flash and +512B RAM for larger firmware or data buffers-making it optimal for feature-rich LCD metering applications without ADC requirements.

FAQ
What is the key functional difference between MSP430F4361IPNR and MSP430F436IPN?
The MSP430F4361IPNR omits the ADC12 module present in the MSP430F436IPN. This is explicitly defined by the "F43x1" family designation, confirmed in the functional block diagram and datasheet notes. As a result, MSP430F4361IPNR cannot perform on-chip 12-bit analog-to-digital conversion but achieves lower active and standby current by excluding that circuitry.
Does MSP430F4361IPNR support LCD drive with 4-mux configuration?
Yes, MSP430F4361IPNR supports LCD drive with up to 160 segments and 4-mux capability using COM0–COM3 backplane outputs and R03–R33 analog bias inputs. This is documented in the functional block diagram and terminal function tables, enabling direct connection to standard 4-mux segment LCDs without external bias generation.
What is the maximum number of I/O pins available on MSP430F4361IPNR?
MSP430F4361IPNR provides 48 general-purpose I/O pins, distributed across Ports P1–P6. This count is consistent across the MSP430x43x1 family and verified in the pin designation diagrams and terminal function tables for the 80-pin PN package.
Can MSP430F4361IPNR operate from a single 3.3 V supply?
Yes, MSP430F4361IPNR operates across 1.8 V to 3.6 V, fully supporting standard 3.3 V supply rails. Its DVCC1/DVCC2 and AVCC pins are rated for 3.3 V, and all specifications-including active current (280 µA at 2.2 V) and wake-up time (<6 µs)-are guaranteed across this full range.
Is the JTAG interface on MSP430F4361IPNR compatible with standard tools like MSP-FET430UIF?
Yes, MSP430F4361IPNR features a standard 4-wire JTAG interface (TCK, TMS, TDO/TDI, TDI/TCLK) fully compatible with TI's MSP-FET430UIF and other compliant debuggers. The pinout matches the MSP430x43x1 family specification, enabling in-circuit emulation, flash programming, and real-time debugging without bootloader dependency.
