Product details
Overview
MSP430F5252IRGCR from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller designed as an "always-on" system controller for portable and battery-powered applications. It features dual-supply operation (DVCC up to 3.6 V, DVIO at 1.62–1.98 V), 128 KB flash, 16 KB RAM, four USCI_A and four USCI_B modules, and consumes 290 µA/MHz in active mode (flash execution) and 1.3 µA in LPM4 shutdown mode.
For engineers reviewing the MSP430F5252IRGCR datasheet, MSP430F5252IRGCR pinout, MSP430F5252IRGCR application, or MSP430F5252IRGCR equivalent, key selection criteria include split-rail I/O compatibility with 1.8-V application processors, fast 3.5-µs wake-up from LPM3, integrated RTC with alarm, hardware multiplier for sensor fusion math, and support for eight concurrent hardware serial interfaces (I²C/SPI/UART).
Technical Context
The MSP430F5252IRGCR implements a unified clock system with FLL stabilization, VLO and REFO internal sources, and support for both 32-kHz XT1 and up to 32-MHz XT2 crystals. Its power-management subsystem includes a programmable LDO core regulator, supply voltage supervision (SVS/SVM), and brownout reset - all enabling robust operation across variable battery conditions.
It integrates three-channel DMA, four 16-bit timers (TA0/TA1/TA2/TB0), a 10-bit 200-ksps ADC with 12 input channels (10 external, 2 internal), comparator_B with 8 channels, and a basic timer with RTC functionality - all accessible via DVIO- or DVCC-powered I/O ports mapped to dedicated peripheral signals.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5254IRGCR | Same 128 KB flash, 16 KB RAM, and peripheral set; differs only in BSL type (UART vs I²C) | Requires UART-based bootloader access instead of I²C; identical runtime behavior and pinout | Select when UART-based firmware updates are preferred and I²C bus is unavailable for BSL |
| MSP430F5253IRGCR | Same memory, timers, and I/O count; includes 10-bit ADC with external/internal reference but no built-in I²C BSL | Lacks I²C-capable bootloader; otherwise functionally identical for sensor hub and data logging use cases | Choose when I²C BSL is unnecessary and cost-sensitive sourcing favors this variant |
Compared with MSP430F5252IRGCR, MSP430F5254IRGCR offers identical performance and power specs but uses UART instead of I²C for bootloader access, while MSP430F5253IRGCR omits I²C BSL entirely - making MSP430F5252IRGCR optimal when secure, isolated I²C-based firmware updates are required alongside full peripheral feature set.

FAQ
What is the maximum operating frequency of the MSP430F5252IRGCR?
The MSP430F5252IRGCR supports a maximum system clock frequency of 25 MHz, enabled by its integrated FLL-controlled DCO and optional external HF crystal (XT2) up to 32 MHz. This allows high-throughput sensor data processing while maintaining ultra-low active-mode current of 290 µA/MHz at 3.0 V during flash execution.
Does the MSP430F5252IRGCR support crystal oscillators for both low- and high-frequency timing?
Yes, the MSP430F5252IRGCR supports dual crystal oscillator inputs: a 32-kHz watch crystal (XT1) on P5.4/P5.5 for RTC and low-power timing, and a high-frequency crystal (XT2) up to 32 MHz on dedicated pins for system clock generation. Both are fully integrated into the unified clock system with automatic FLL stabilization.
How many I/O pins on the MSP430F5252IRGCR operate at 1.8 V?
The MSP430F5252IRGCR supports up to 35 general-purpose I/O pins powered by the DVIO supply rail, which operates within 1.62 V to 1.98 V - fully compatible with 1.8-V logic interfaces. These include all pins in Port 1, Port 2, Port 3, Port 4, Port 7, and selected control signals like RST/NMI and BSLEN.
Can the MSP430F5252IRGCR perform ADC conversions while in low-power mode?
Yes, the MSP430F5252IRGCR can execute ADC10_A conversions in LPM0 and LPM3 modes using ACLK or SMCLK sourced from VLO or REFO. The ADC module retains full functionality with internal reference and sample-and-hold, enabling periodic sensor readings at µA-level system current without waking the CPU.
What bootloader interface does the MSP430F5252IRGCR support?
The MSP430F5252IRGCR features an I²C-capable bootloader (BSL) accessible via USCI_B0, allowing secure, two-wire firmware updates without requiring JTAG or additional programming hardware. This I²C BSL implementation is confirmed in the device comparison table and supported across all RGC-package variants of the F525x family.
