Product details
Overview
MSP430F4361IPZR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 24KB+256B flash memory, 1KB RAM, integrated LCD driver for up to 160 segments, dual 16-bit timers (Timer_A3 and Timer_B3), and serial communication via USART0. 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 MSP430F4361IPZR datasheet, MSP430F4361IPZR pinout, MSP430F4361IPZR application, or MSP430F4361IPZR equivalent, key selection considerations include its 100-pin QFP package, absence of ADC12 module (per F43x1 family designation), wake-up time under 6 µs from standby, and LCD segment drive capability with four COM lines and 40 segment outputs.
Technical Context
The MSP430F4361IPZR 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 two 16-bit timers with capture/compare registers, one USART (USART0) configurable as UART or SPI, on-chip comparator, supply voltage supervisor, and LCD controller supporting static to 4-mux configurations.
Unlike MSP430F436IPZ, the MSP430F4361IPZR omits the 12-bit ADC12 module entirely - confirmed by family documentation stating "ADC12 module is not implemented" on all x43x1/x44x1 variants. It retains full LCD, timer, and communication functionality, making it suitable for display-centric applications where analog sensing is handled externally or omitted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 125-ns instruction cycle; enables efficient code execution in resource-constrained embedded systems. |
| Flash / RAM | 24KB+256B flash memory and 1KB RAM; supports firmware updates and real-time data buffering in metering applications. |
| Supply Voltage | 1.8 V to 3.6 V operation; compatible with single-cell Li-ion, alkaline, or coin-cell power sources without external regulation. |
| Active Current | 280 µA at 1 MHz, 2.2 V; minimizes battery drain during active sensor polling or display refresh cycles. |
| Standby Current | 1.1 µA; enables multi-year operation in always-on LCD display modes with periodic wake-up events. |
| LCD Drive | Supports up to 160 segments with 1–4 multiplexing and four COM lines; drives alphanumeric or custom segment displays directly. |

Pinout & Package
Package: 100-pin plastic quad flat pack (PZ), 14 mm × 14 mm, 0.5 mm pitch, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST/NMI | Reset / Non-maskable interrupt input | Hardware reset initiation or high-priority event handling; critical for system recovery and fault detection. |

| P2.4/UTXD0 | USART0 transmit data output | Drives serial data to external host or modem; requires pull-up for open-drain UART bus compatibility. |
| P2.5/URXD0 | USART0 receive data input | Accepts asynchronous serial input; supports baud rates up to 1 Mbps with internal clock synchronization. |
| COM0–COM3 | LCD backplane outputs | Four common outputs enable 4-mux LCD drive; reduce external component count in display subsystems. |
| S0–S39 | LCD segment outputs | 40 dedicated segment drivers (plus S10–S39 mapping) support up to 160-segment displays with minimal external circuitry. |
| TCK/TMS/TDO/TDI | JTAG debug interface | Enables full-speed in-circuit emulation, flash programming, and boundary-scan testing without bootloader dependency. |
Key Features
| Feature | Design Value |
|---|---|
| Five low-power modes | Enables dynamic power scaling - e.g., LCD refresh in LPM3 (1.1 µA) while preserving RAM and register state. |
| Integrated LCD controller | Eliminates need for external segment drivers; supports static, 2-, 3-, or 4-mux displays with software-configurable bias and frame frequency. |
| Bootstrap loader (BSL) | Allows field firmware updates via UART using standard PC tools; no external programmer required for production rework. |
| Programmable code protection | Security fuse prevents unauthorized read-out of flash contents; protects proprietary algorithms and calibration data. |
| Supply voltage supervisor | Detects brownout conditions and triggers reset before logic corruption occurs; programmable threshold avoids false triggers during battery sag. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F436IPZ | Includes 12-bit ADC12 module (8 channels, <10 µs conversion); otherwise identical flash/RAM/peripherals/package. | Required when on-chip analog sensing (e.g., battery voltage, thermistor) is needed without external ADC. | Select MSP430F436IPZ only if ADC functionality is mandatory; MSP430F4361IPZR reduces cost and simplifies design when ADC is unnecessary. |
| MSP430F4371IPZ | 32KB+256B flash, 1KB RAM; same peripherals and pinout as MSP430F4361IPZ but with larger program memory. | Suitable for applications requiring more complex UI logic, cryptographic routines, or future firmware expansion headroom. | Choose MSP430F4371IPZ when firmware size exceeds 24KB or long-term feature scalability is prioritized over minimal BOM cost. |
Compared with MSP430F436IPZ, the MSP430F4361IPZR removes ADC12 to lower cost and power, while MSP430F4371IPZ trades memory density for future-proofing - both retain identical LCD, timer, and communication capabilities in the same 100-pin PZ package.

FAQ
What is the primary functional difference between MSP430F4361IPZR and MSP430F436IPZR?
The MSP430F4361IPZR excludes the 12-bit ADC12 module present in the MSP430F436IPZR. All other peripherals - including 24KB+256B flash, 1KB RAM, dual 16-bit timers, USART0, LCD controller, and JTAG interface - are functionally identical. This omission reduces cost and power consumption where analog-to-digital conversion is handled externally or not required.
Does MSP430F4361IPZR support LCD displays with more than 160 segments?
No. The MSP430F4361IPZR supports up to 160 segments using its integrated LCD controller with four COM lines and software-configurable multiplexing (1–4 mux). Driving more than 160 segments requires external LCD drivers or a higher-pin-count variant such as MSP430F4491IPZ, which supports up to 160 segments but with expanded timer resources - not additional segment count.
What is the maximum operating frequency of the CPU in MSP430F4361IPZR?
The MSP430F4361IPZR CPU achieves a 125-ns instruction cycle time, corresponding to a maximum effective clock frequency of 8 MHz. This is delivered by the integrated digitally controlled oscillator (DCO) with FLL+ enhancement, allowing stable operation across voltage and temperature without external crystals for core timing.
Can MSP430F4361IPZR be programmed in-system without a dedicated JTAG emulator?
Yes. The MSP430F4361IPZR includes a factory-programmed bootstrap loader (BSL) accessible via UART (pins P2.4/UTXD0 and P2.5/URXD0). This allows firmware updates using only a UART-to-USB converter and TI's BSL Scripter tool - no JTAG hardware is required for field programming or initial loading.
Is the pinout of MSP430F4361IPZR compatible with other devices in the MSP430x43x1 family?
Yes. The MSP430F4361IPZR shares identical pinout and package (100-pin PZ) with all other MSP430x43x1 devices including MSP430F4351IPZ and MSP430F4371IPZ. This enables hardware reuse across variants differing only in flash size (16KB/24KB/32KB) and RAM (512B/1KB), simplifying board design and qualification.
