Product details
Overview
MSP430F5259IRGCT from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller with dual-supply operation (DVCC/DVIO), 128 KB flash, 32 KB RAM, and four USCI_A + four USCI_B modules for concurrent UART/IrDA/SPI/I²C communication. It delivers 290 µA/MHz active current at 3.0 V and wakes from LPM3 in 3.5 µs, targeting always-on sensor hub and power-management controller applications.
For engineers reviewing the MSP430F5259IRGCT datasheet, MSP430F5259IRGCT pinout, MSP430F5259IRGCT application, or MSP430F5259IRGCT equivalent, key selection criteria include split-rail I/O (1.8 V DVIO/1.8–3.6 V DVCC), RTC-integrated standby mode (2.1 µA @ 2.2 V), 35 general-purpose I/Os, 10-bit ADC with internal reference, and hardware multiplier support for real-time sensor fusion.
Technical Context
The MSP430F5259IRGCT implements a unified clock system with FLL stabilization, VLO and REFO internal sources, XT1 (32 kHz) and XT2 (up to 32 MHz) crystal support, and programmable LDO core regulation. Its power architecture separates DVCC (1.8–3.6 V) and DVIO (1.62–1.98 V) rails to enable direct interfacing with 1.8-V application processors without level shifters.
Peripherals include four 16-bit timers (TA0/TA1/TA2/TB0), 10-bit ADC10_A with 12 channels (10 external, 2 internal), comparator_B (8-channel), CRC16 module, and 3-channel DMA - all operating under flexible low-power modes (LPM0–LPM4.5) with full RAM retention down to 1.3 µA in LPM4.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5252IRGCT | 128 KB flash but only 16 KB RAM; same pinout, peripherals, and power specs | Suitable where sensor algorithm memory footprint is ≤16 KB; reduces cost without changing PCB | Select when RAM demand is lower and BOM cost optimization is prioritized over future firmware scalability |
| MSP430F5255IRGCT | Identical memory and peripherals but BSL configured for UART-only instead of I²C; same package and electrical specs | Preferred in designs requiring UART-based field firmware updates and no I²C bootloading path | Choose when production programming uses UART exclusively and I²C bootloader functionality is unnecessary |
Compared with MSP430F5252IRGCT and MSP430F5255IRGCT, the MSP430F5259IRGCT provides double the RAM (32 KB vs. 16 KB) and I²C-capable BSL - making it optimal for complex sensor fusion and flexible field update requirements without hardware redesign.

FAQ
What is the maximum operating frequency of the MSP430F5259IRGCT?
The MSP430F5259IRGCT supports a maximum system clock frequency of 25 MHz, enabled by its integrated FLL control loop and support for high-frequency crystals up to 32 MHz on the XT2 oscillator. This allows deterministic real-time execution of sensor fusion algorithms and high-speed serial communication while maintaining ultra-low power consumption in active mode.
Does the MSP430F5259IRGCT support crystal oscillators for real-time clock operation?
Yes, the MSP430F5259IRGCT supports 32-kHz watch crystals via the XT1 oscillator on P5.4 (XIN) and P5.5 (XOUT), enabling precise RTC operation with crystal accuracy. The RTC_A module retains timekeeping functionality in LPM3 standby mode at just 2.1 µA, making it suitable for battery-backed time-critical applications.
How many serial communication interfaces does the MSP430F5259IRGCT integrate?
The MSP430F5259IRGCT integrates eight hardware serial interfaces: four USCI_A modules (each configurable as UART, IrDA, or SPI) and four USCI_B modules (each configurable as I²C or SPI). This enables concurrent communication with multiple sensors, displays, radios, and host processors without software bit-banging or resource contention.
What is the purpose of the DVIO supply pin on the MSP430F5259IRGCT?
The DVIO supply pin powers the 1.8-V I/O domain (P1–P4, P7, PJ) of the MSP430F5259IRGCT and must be supplied independently at 1.62–1.98 V. This enables seamless interfacing with 1.8-V application processors, FPGAs, and sensors without external level translators - reducing system cost and signal integrity risk.
Can the MSP430F5259IRGCT perform analog-to-digital conversion without external reference components?
Yes, the MSP430F5259IRGCT includes an internal 1.5-V and 2.5-V reference generator for the 10-bit ADC10_A module. It supports single-ended and differential conversions across 12 channels (10 external, 2 internal) with sample rates up to 200 ksps - eliminating the need for external voltage references in most precision sensing applications.
