Product details
Overview
MSP430F5244IRGZT from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128 KB flash, 8 KB RAM, a 10-bit ADC with 8 external + 2 internal channels, three 16-bit Timer_A modules (5/3/3 capture/compare registers), one 16-bit Timer_B (7 registers), two USCI peripherals (UART/IrDA/SPI/I²C), RTC, hardware multiplier, and DMA - deployed in battery-powered sensor nodes and portable data loggers.
For engineers reviewing the MSP430F5244IRGZT datasheet, MSP430F5244IRGZT pinout, MSP430F5244IRGZT application, or MSP430F5244IRGZT equivalent, key selection criteria include LPM4.5 shutdown current (0.18 µA), 3.5 µs wake-up time from LPM3, VQFN-48 package (7 mm × 7 mm), integrated LDO core regulation, and ADC channel count versus F5249/F5247 variants.
Technical Context
The MSP430F5244IRGZT implements a CPUXV2 16-bit RISC core with constant generators and unified clock system including FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management unit integrates an LDO with programmable VCORE, SVM/SVS supervision, and brownout reset.
Peripherals are mapped via port mapping control (P4) and support flexible I/O configuration: 37 GPIOs (including Schmitt-trigger inputs and full/reduced drive strength outputs), 6-channel Comparator_B, and dual USCI modules enabling concurrent UART/IrDA/SPI on USCI_A and I²C/SPI on USCI_B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | CPUXV2 16-bit RISC with constant generators; enables high code efficiency for low-cycle sensor polling and interrupt-driven event handling. |

FAQ
What is the maximum system clock frequency supported by the MSP430F5244IRGZT?
The MSP430F5244IRGZT supports up to 25 MHz system clock frequency using the FLL-controlled DCO or external XT2 crystal oscillator (up to 32 MHz). This enables high-speed signal processing while maintaining ultra-low-power operation through dynamic clock gating and low-power modes.
Does the MSP430F5244IRGZT include an integrated real-time clock (RTC)?
Yes, the MSP430F5244IRGZT includes a dedicated RTC_A module with calendar functionality, alarm capability, and automatic compensation for leap years. It operates from the 32-kHz XT1 crystal in LPM3 mode with only 1.9 µA current draw at 3.0 V, enabling precise timekeeping during deep sleep.
How many universal serial communication interfaces (USCIs) does the MSP430F5244IRGZT have, and what protocols do they support?
The MSP430F5244IRGZT has two USCI modules: USCI_A0 and USCI_B0. USCI_A0 supports enhanced UART (with auto-baud detection), IrDA, and synchronous SPI. USCI_B0 supports I²C and synchronous SPI. Both operate independently, allowing concurrent use of UART for debugging and I²C for sensor communication.
What is the ADC resolution and sampling rate of the MSP430F5244IRGZT?
The MSP430F5244IRGZT features a 10-bit successive-approximation ADC (ADC10_A) with a maximum sampling rate of 200 ksps. It supports 8 external analog inputs and 2 internal references (VeREF+ and VeREF−), enabling simultaneous monitoring of multiple sensors without external multiplexing.
Is the MSP430F5244IRGZT pin-compatible with other devices in the MSP430F52xx family?
The MSP430F5244IRGZT shares the same 48-pin RGZ package and pinout with MSP430F5242IRGZT, enabling direct substitution where firmware fits within 64 KB flash. It is not pin-compatible with 64-pin variants (e.g., MSP430F5247IRGCT) due to differing pin counts and physical layout.
