Texas Instruments MSP430F448IPZR

Overview

MSP430F448IPZR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 48KB+256B flash memory, 2KB RAM, integrated 160-segment LCD driver, dual USARTs, and a 12-bit ADC with internal reference. It operates from 1.8 V to 3.6 V and supports wake-up from standby in under 6 µs-ideal for battery-powered metering and portable instrumentation.

For engineers reviewing the MSP430F448IPZR datasheet, MSP430F448IPZR pinout, MSP430F448IPZR application, or MSP430F448IPZR equivalent, key selection criteria include its 100-pin QFP package, dual UART/SPI capability, 7-channel Timer_B with shadow registers, hardware multiplier, and LCD segment drive up to 160 segments without external bias circuitry.

Technical Context

The MSP430F448IPZR 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 architecture integrates two 16-bit timers (Timer_A with three capture/compare registers and Timer_B with seven capture/compare registers plus shadow registers), supporting precise PWM generation and event timing in industrial control loops.

It includes a 12-bit ADC12 module with sample-and-hold, autoscan, and internal reference-fully functional per family documentation for MSP430x44x devices-and dual USARTs configurable as asynchronous UART or synchronous SPI, with independent clock sources and dedicated I/O pins for each interface.

FAQ

What is the maximum operating frequency of the MSP430F448IPZR?

The MSP430F448IPZR features a digitally controlled oscillator (DCO) that supports up to 8 MHz system clock (MCLK) operation. Its 16-bit RISC core achieves a 125-ns instruction cycle time at this frequency, enabling responsive real-time control while maintaining ultralow power consumption in active mode.

Does the MSP430F448IPZR include an integrated ADC, and what are its key specifications?

Yes, the MSP430F448IPZR includes a fully functional 12-bit ADC12 module with 8 input channels, <10 µs conversion time, internal reference voltage, sample-and-hold, and autoscan capability. This ADC is confirmed active in the MSP430x44x series and supports simultaneous multi-channel acquisition without external components.

How many USART interfaces does the MSP430F448IPZR support, and how are they configured?

The MSP430F448IPZR supports two independent USART modules (USART0 and USART1), each configurable in software as either asynchronous UART or synchronous SPI. USART0 uses P2.4/UTXD0 and P2.5/URXD0, while USART1 uses P4.0/UTXD1 and P4.1/URXD1-providing true dual-protocol serial connectivity.

What LCD segment count and multiplexing options does the MSP430F448IPZR support?

The MSP430F448IPZR integrates an LCD controller supporting up to 160 segments with 1-, 2-, 3-, or 4-mux configurations. It provides four common outputs (COM0–COM3) and up to 40 segment outputs (S0–S39), enabling direct drive of alphanumeric or graphical LCDs without external bias circuitry.

Is the MSP430F448IPZR pin-compatible with other devices in the MSP430x44x family?

Yes, the MSP430F448IPZR shares the same 100-pin PZ package and pinout with MSP430F447IPZR and MSP430F449IPZR, including identical signal assignments for power, JTAG, timers, USARTs, ADC, and LCD terminals-enabling hardware reuse across memory variants.
