Product details
Overview
MSP430F447IPZ from Texas Instruments is a 16-bit ultralow-power mixed-signal microcontroller featuring 32KB+256B flash memory, 1KB RAM, integrated 12-bit ADC with internal reference and autoscan, dual 16-bit timers (Timer_A3 and Timer_B7), two USARTs, and an LCD driver supporting up to 160 segments - deployed in battery-powered portable measurement and display systems.
For engineers reviewing the MSP430F447IPZ datasheet, MSP430F447IPZ pinout, MSP430F447IPZ application, or MSP430F447IPZ equivalent, key selection criteria include its 100-pin QFP package, 1.8–3.6 V supply range, <6 µs wake-up from standby, 12-bit ADC conversion time under 10 µs, and dual USART support for simultaneous UART/SPI communication in sensor and metering designs.
Technical Context
The MSP430F447IPZ implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling sub-6 µs wake-up from standby mode and five configurable low-power modes optimized for extended battery life. Its architecture integrates peripheral modules directly on-chip without external glue logic.
It features a hardware multiplier (MPY/MPYS/MAC/MACS) and supports both synchronous (SPI) and asynchronous (UART) serial communication via two independent USART modules - USART0 and USART1 - each configurable in software. The 12-bit ADC includes sample-and-hold, internal reference, and autoscan across eight channels.

FAQ
What is the maximum operating frequency of the MSP430F447IPZ?
The MSP430F447IPZ operates at a maximum CPU frequency of 8 MHz using the integrated FLL+ oscillator. Its 125-ns instruction cycle time enables deterministic real-time execution, and the DCO allows fast wake-up from low-power modes while maintaining timing accuracy for sensor sampling and display refresh cycles. The MSP430F447IPZ does not require external high-speed crystals for core operation.
Does the MSP430F447IPZ include an integrated LCD driver?
Yes, the MSP430F447IPZ includes a fully integrated LCD controller/driver supporting up to 160 segments with 1/2–1/4 bias, programmable frame frequency, and dedicated COM0–COM3 outputs. It drives standard static, multiplexed, or low-power LCD glass without external components - confirmed by functional block diagrams and terminal function tables in SLAS344G. This capability is retained across all MSP430F44x variants including the MSP430F447IPZ.
How many USART modules does the MSP430F447IPZ support?
The MSP430F447IPZ supports two independent USART modules: USART0 and USART1. Each can be configured in software as either asynchronous UART or synchronous SPI mode. Pin assignments (e.g., P2.4/P2.5 for USART0, P4.0/P4.1 for USART1) and functional block diagrams in SLAS344G confirm dual-serial capability - distinguishing it from the MSP430F43x series which supports only one USART.
What is the ADC resolution and channel count of the MSP430F447IPZ?
The MSP430F447IPZ integrates a 12-bit successive-approximation ADC (ADC12) with eight input channels, internal reference, sample-and-hold, and autoscan functionality. Conversion time is under 10 µs, and analog inputs are accessible via P6.0–P6.7 (A0–A7). This ADC configuration is explicitly documented for the MSP430F44x series in SLAS344G and applies directly to the MSP430F447IPZ.
What package type and pin count does the MSP430F447IPZ use?
The MSP430F447IPZ uses a 100-pin plastic quad flat pack (PZ package), measuring 14 mm × 14 mm with 0.5 mm lead pitch. Pinout details - including dedicated LCD COM outputs, dual USART signal routing, and ADC input mapping - are fully specified in the "pin designation, MSP430x447IPZ" section of SLAS344G. This package is distinct from the 80-pin PN variant used by lower-pin-count family members.
