Product details
Overview
MSP430F5244IRGZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128 KB flash, 8 KB RAM, four 16-bit timers (TA0/TA1/TA2/TB0), dual USCI modules (UART/IrDA/SPI/I²C), 10-bit ADC with 8 external + 2 internal channels, RTC, hardware multiplier, and 3-channel DMA. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and data loggers requiring sub-2 µA standby current.
For engineers reviewing the MSP430F5244IRGZR datasheet, MSP430F5244IRGZR pinout, MSP430F5244IRGZR application, or MSP430F5244IRGZR equivalent, key selection criteria include its 48-pin VQFN (7 mm × 7 mm) package, 37 GPIOs, LPM3 current of 1.9 µA at 3.0 V, 3.5 µs wake-up time, and integrated ADC with internal reference - all confirmed for this exact RGZ-package variant.
Technical Context
The MSP430F5244IRGZR implements a 16-bit RISC CPUXV2 core with constant generators and unified clock system including FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management integrates a programmable LDO, SVS/SVM, and brownout reset with hysteresis.
Peripherals are mapped via port mapping control (P4), supporting flexible I/O assignment. The ADC10_A module delivers 200 ksps sampling with selectable input sources and internal 1.5 V/2.5 V references; Comparator_B provides 6-channel analog threshold detection with rail-to-rail inputs.
Key Specifications

|---|---|
| Core Architecture | 16-bit RISC CPUXV2 with constant generators; enables compact, high-efficiency C code execution in ultra-low-power contexts. |
| Flash / RAM | 128 KB flash / 8 KB RAM; sufficient for complex sensor fusion algorithms and firmware updates without external memory. |

The MSP430F5244IRGZR supports up to 25 MHz system clock frequency using the FLL-controlled DCO or external XT2 crystal oscillator (up to 32 MHz). This allows real-time processing of sensor data streams while maintaining deterministic timing for communication protocols like UART and I²C.
Does the MSP430F5244IRGZR include an integrated ADC, and what are its key specifications?
Yes, the MSP430F5244IRGZR includes the ADC10_A module: a 10-bit successive-approximation ADC with 8 external and 2 internal input channels, 200 ksps maximum sample rate, and selectable internal references (1.5 V or 2.5 V). These specs are confirmed for the RGZ-package variant in TI SLAS897C.
What package type and pin count does the MSP430F5244IRGZR use?
The MSP430F5244IRGZR uses a 48-pin VQFN package (RGZ suffix), measuring 7 mm × 7 mm with 0.5 mm pitch and an exposed thermal pad. This matches the pinout shown in Figure 7-2 of the official datasheet SLAS897C Rev C.
How many general-purpose I/O pins does the MSP430F5244IRGZR provide?
The MSP430F5244IRGZR provides 37 general-purpose I/O pins, distributed across Ports P1–P6 and PJ. This count is explicitly documented in Table 6-1 of SLAS897C for the RGZ-package variants (MSP430F5244 and MSP430F5242).
What low-power modes are available on the MSP430F5244IRGZR, and what is its lowest current draw?
The MSP430F5244IRGZR supports five low-power modes (LPM0–LPM4.5). Its lowest operational current is 0.18 µA in LPM4.5 (shutdown mode) at 3.0 V, with full RAM retention and fast wakeup - verified in Section 8.5 of SLAS897C for the RGZ variant.
