Product details
Overview
MSP430F5229IRGCR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128 KB Flash, 8 KB RAM, dual-supply operation (DVCC 1.8–3.6 V / DVIO 1.62–1.98 V), 10-bit ADC with 12 channels (10 external + 2 internal), and four 16-bit timers - including Timer_A with 5/3/3 capture/compare registers and Timer_B with 7 registers. It targets battery-powered sensor systems requiring RTC, low-power wake-up (<3.5 µs), and dual-voltage I/O interfacing.
For engineers reviewing the MSP430F5229IRGCR datasheet, MSP430F5229IRGCR pinout, MSP430F5229IRGCR application, or MSP430F5229IRGCR equivalent, key selection criteria include its 64-pin VQFN package, split I/O supply architecture, 22 DVCC + 31 DVIO GPIOs, integrated hardware multiplier, three-channel DMA, and dual USCI modules supporting UART/IrDA/SPI/I²C - all optimized for energy-constrained embedded measurement.
Technical Context
The MSP430F5229IRGCR implements a unified clock system with FLL stabilization, low-frequency VLO and trimmed REFO sources, 32-kHz XT1 crystal support, and up to 32-MHz XT2 capability. Its power-management system integrates a programmable LDO core regulator, supply voltage supervision (SVM/SVS), and brownout reset.
Peripherals include two USCI_A modules (UART/IrDA/SPI) and two USCI_B modules (I²C/SPI), a 200-KSPS 10-bit ADC10_A with internal reference and sample-and-hold, an 8-channel Comparator_B, RTC_A with alarm, CRC16 engine, and MPY32 hardware multiplier - all accessible via configurable port mapping.

FAQ
What is the maximum system clock frequency supported by the MSP430F5229IRGCR?
The MSP430F5229IRGCR supports a maximum system clock frequency of 25 MHz from its digitally controlled oscillator (DCO), and up to 32 MHz when using the high-frequency crystal oscillator (XT2) with external crystal. This allows flexible trade-offs between power efficiency and processing throughput depending on application demands.
Does the MSP430F5229IRGCR include an integrated real-time clock (RTC)?
Yes, the MSP430F5229IRGCR includes a dedicated RTC_A module with calendar mode, alarm functionality, and automatic leap-year compensation. It operates in LPM3 with a 32.768-kHz crystal connected to P5.4/XIN and P5.5/XOUT, drawing only 1.9 µA at 3.0 V - enabling precise timekeeping during ultra-low-power operation.
How many analog input channels does the MSP430F5229IRGCR's 10-bit ADC support?
The MSP430F5229IRGCR's ADC10_A module supports 12 total input channels: 10 external analog inputs (A0–A9 on P6.0–P6.7 and P5.0–P5.1) plus 2 internal references (VeREF+ and VeREF−). This configuration enables simultaneous monitoring of multiple sensors while retaining internal calibration capability.
Can the MSP430F5229IRGCR operate with separate I/O and core supply voltages?
Yes, the MSP430F5229IRGCR features a dual-supply architecture: DVCC (1.8–3.6 V) powers the core and DVCC-domain GPIOs, while DVIO (1.62–1.98 V) powers the DVIO-domain GPIOs. This allows direct interfacing with 1.8-V peripherals without external level-shifting circuitry - reducing BOM cost and board space.
What debug interface does the MSP430F5229IRGCR use, and how many pins are required?
The MSP430F5229IRGCR uses the Spy-Bi-Wire (SBW) interface, a 2-wire variant of JTAG, implemented on TEST/SBWTCK (pin 19) and RSTDVCC/SBWTDIO (pin 64). Only two dedicated pins plus ground are required for full programming, debugging, and boundary-scan access - simplifying test fixture design and PCB layout.
