Product details
Overview
MSP430F5229IRGCT from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128 KB Flash, 8 KB RAM, dual-supply I/O (DVCC/DVIO), 10-bit ADC with 12 channels (10 external + 2 internal), four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), and RTC with alarm-designed for battery-powered sensor systems and data loggers.
For engineers reviewing the MSP430F5229IRGCT datasheet, MSP430F5229IRGCT pinout, MSP430F5229IRGCT application, or MSP430F5229IRGCT equivalent, key selection criteria include its 64-pin VQFN package, split 1.8-V/3.3-V I/O supply architecture, sub-2 µA LPM3 current at 3.0 V, 3.5 µs wake-up time, and integrated hardware multiplier for efficient signal processing in constrained-energy embedded designs.
Technical Context
The MSP430F5229IRGCT implements a unified clock system with FLL stabilization, dual crystal support (XT1 for 32-kHz RTC, XT2 up to 32 MHz), and three internal sources (VLO, REFO, DCO). Its power management includes an on-chip LDO with programmable core voltage and SVM/SVS monitoring across both DVCC and DVIO rails.
Peripherals are mapped via port multiplexing with configurable drive strength (full/reduced) and Schmitt-trigger inputs segmented by voltage domain-DVCC-domain I/O (e.g., P1.0–P1.3, P6.x) and DVIO-domain I/O (e.g., P1.4–P1.7, P2.x, P4.x)-enabling seamless interfacing with 1.8-V logic without external level shifters.
Key Specifications

FAQ
What is the maximum operating frequency of the MSP430F5229IRGCT?
The MSP430F5229IRGCT supports a maximum system clock frequency of 25 MHz, enabled by its integrated FLL-controlled DCO and optional high-frequency crystal (XT2) up to 32 MHz. This allows real-time processing of sensor data streams while maintaining ultra-low active-mode current of 290 µA/MHz at 3.0 V during Flash execution.
Does the MSP430F5229IRGCT support hardware-based cryptographic acceleration?
No, the MSP430F5229IRGCT does not include dedicated cryptographic accelerators such as AES or SHA engines. It relies on software-based implementations for security functions. For hardware crypto, consider TI's MSP432E4 or SimpleLink™ CC series MCUs-MSP430F5229IRGCT focuses on ultra-low-power analog/mixed-signal control, not secure connectivity.
Can the MSP430F5229IRGCT operate with only the DVIO supply active?
No-the MSP430F5229IRGCT requires both DVCC (1.8–3.6 V) and DVIO (1.62–1.98 V) supplies to be powered for functional operation. DVCC powers the core, Flash, RAM, and DVCC-domain I/O; DVIO powers DVIO-domain I/O and certain peripheral logic. Omitting either rail causes undefined behavior or failure to initialize.
What is the purpose of the RSTDVCC pin on the MSP430F5229IRGCT?
The RSTDVCC pin on the MSP430F5229IRGCT serves as the single-wire debug (SBW) test interface I/O line-functioning as SBWTDIO for bidirectional communication with TI's MSP-FET debugger. It must be pulled high via a 47-kΩ resistor to DVCC during normal operation and is shared with the RST/NMI function in SBW mode.
How many external interrupt-capable pins does the MSP430F5229IRGCT have?
The MSP430F5229IRGCT provides up to 12 external interrupt-capable pins: 4 on DVCC-domain ports (P1.0–P1.3) and 8 on DVIO-domain ports (P1.4–P1.7, P2.0–P2.7). Each supports configurable edge sensitivity and wake-up from all low-power modes, enabling responsive event-driven system design.
