Product details
Overview
MSP430F5229IYFFT from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128 KB Flash, 8 KB RAM, dual-supply operation (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. It targets battery-powered sensor systems and data loggers requiring sub-2 µA standby current and 3.5 µs wake-up.
For engineers reviewing the MSP430F5229IYFFT datasheet, MSP430F5229IYFFT pinout, MSP430F5229IYFFT application, or MSP430F5229IYFFT equivalent, key selection criteria include its split I/O supply (DVIO 1.62–1.98 V), 64-pin DSBGA package, 22 DVCC I/O + 31 DVIO I/O count, integrated hardware multiplier, and LPM4.5 shutdown current of 0.18 µA at 3.0 V.
Technical Context
The MSP430F5229IYFFT 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 includes an integrated LDO with programmable core voltage and SVM/SVS monitoring.
Peripherals are mapped via port mapping control (P4) and support flexible interrupt routing. The device uses a split I/O domain architecture: DVCC-supplied pins (e.g., P1.0–P1.3, P6.x) operate at 1.8–3.6 V, while DVIO-supplied pins (e.g., P1.4–P1.7, P2.x, P4.x) operate at 1.62–1.98 V-enabling direct interface to 1.8-V logic without level shifters.

FAQ
What is the operating voltage range for the DVIO supply of the MSP430F5229IYFFT?
The DVIO supply for the MSP430F5229IYFFT operates from 1.62 V to 1.98 V, enabling direct interface with 1.8-V logic and analog components without external level-shifting circuitry. This rail powers pins P1.4–P1.7, P2.x, P4.x, P7.x, and BSLEN. Operation outside this range may cause I/O malfunction or damage.
Does the MSP430F5229IYFFT support crystal oscillators for both low- and high-frequency clocks?
Yes, the MSP430F5229IYFFT supports dual crystal oscillator inputs: XT1 accepts a 32-kHz watch crystal for ACLK and RTC operation, while XT2 supports crystals up to 32 MHz for MCLK and SMCLK generation. Both are accessible on P5.4/P5.5 (XIN/XOUT) and P5.2/P5.3 (XT2IN/XT2OUT), respectively.
How many external analog input channels does the ADC10_A module support on the MSP430F5229IYFFT?
The ADC10_A module on the MSP430F5229IYFFT supports 10 external analog input channels (A0–A9), mapped to P6.0–P6.7 and P5.0–P5.1. Two additional internal channels (VeREF+ and VeREF−) provide reference monitoring capability, enabling self-calibration and supply tracking.
What is the minimum wake-up time from LPM3 to active mode for the MSP430F5229IYFFT?
The MSP430F5229IYFFT wakes from LPM3 to active mode in 3.5 µs (typical), measured from interrupt assertion to first instruction execution. This fast wake-up is enabled by the FLL-stabilized DCO and applies across the full operating voltage range (1.8–3.6 V), ensuring deterministic real-time response in duty-cycled applications.
Is the MSP430F5229IYFFT pin-compatible with other devices in the MSP430F522x family?
Yes, the MSP430F5229IYFFT shares identical pinout and package (64-ball DSBGA, YFF) with MSP430F5227IYFFT, MSP430F5219IYFFT, and MSP430F5217IYFFT. Firmware and hardware designs are interchangeable across these variants, differing only in Flash size (128 KB vs. 64 KB) and ADC presence (F522x has ADC; F521x does not).
