Product details
Overview
MSP430F5222IRGZT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 64 KB Flash, 8 KB RAM, dual-supply I/O (DVCC/DVIO), 10-bit ADC (8 external + 2 internal channels), two USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers, RTC, hardware multiplier, and DMA - designed for battery-powered sensor systems and data loggers.
For engineers reviewing the MSP430F5222IRGZT datasheet, MSP430F5222IRGZT pinout, MSP430F5222IRGZT application, or MSP430F5222IRGZT equivalent, key selection criteria include its 48-pin VQFN (RGZ) package, split-rail I/O (1.62–1.98 V DVIO), sub-2 µA LPM3 current, 3.5 µs wake-up time, and integrated ADC with internal reference - critical for precision analog sensing in constrained power budgets.
Technical Context
The MSP430F5222IRGZT implements a unified clock system with FLL stabilization, VLO/REFO/XT1/XT2 sources, and programmable LDO core regulation. Its dual-supply architecture isolates DVIO (1.62–1.98 V) from DVCC (1.8–3.6 V), enabling direct interface to 1.8-V peripherals without level shifters.
It integrates three USCI modules (USCI_A0/A1/B0) supporting UART with auto-baud detection, IrDA, SPI master/slave, and I²C - all configurable via register-level control. The 10-bit ADC10_A operates up to 200 kSPS with sample-and-hold, selectable internal reference (1.5 V/2.0 V/2.5 V), and 8 external analog inputs mapped across P6.x and P5.x pins.

FAQ
What is the maximum operating frequency of the MSP430F5222IRGZT?
The MSP430F5222IRGZT supports a maximum system clock frequency of 25 MHz, enabled by its digitally controlled oscillator (DCO) with FLL stabilization. This allows high-speed execution while maintaining ultra-low-power operation - for example, achieving 290 µA/MHz in active mode at 8 MHz and 3.0 V. The actual achievable frequency depends on supply voltage and temperature, with full 25-MHz operation specified at DVCC ≥ 2.2 V.
Does the MSP430F5222IRGZT support crystal oscillators for both low- and high-frequency operation?
Yes, the MSP430F5222IRGZT supports dual crystal oscillators: XT1 accepts 32-kHz watch crystals for RTC and low-frequency timing, while XT2 supports high-frequency crystals up to 32 MHz for system clock generation. Pins P5.4/XIN and P5.5/XOUT are dedicated to XT1; P5.2/XT2IN and P5.3/XT2OUT serve XT2. Both oscillators include fault detection and automatic failover to internal sources (VLO/REFO) if external crystals stop.
How many analog input channels does the MSP430F5222IRGZT ADC support, and what reference options are available?
The MSP430F5222IRGZT integrates the ADC10_A module with 8 external analog input channels (A0–A7 on P6.x and P5.x) plus 2 internal references (temperature sensor and VCC/2). It supports selectable internal references of 1.5 V, 2.0 V, or 2.5 V, and accepts external references up to AVCC. The ADC achieves 200 kSPS with integral nonlinearity (INL) of ±1 LSB and supports sample-and-hold for accurate multi-channel acquisition.
What debug interface does the MSP430F5222IRGZT use, and is JTAG required?
The MSP430F5222IRGZT supports both Spy-Bi-Wire (SBW) and JTAG debug interfaces. SBW uses a single bidirectional pin (RSTDVCC/SBWTDIO) plus ground, making it ideal for space-constrained designs; JTAG requires four pins (TCK/TMS/TDI/TDO) and is supported via PJ.x pins. No external programming voltage is needed - onboard serial programming works via SBW or JTAG using standard TI tools like MSP-FET or LaunchPad debuggers.
Can the MSP430F5222IRGZT operate with different supply voltages for core and I/O domains?
Yes, the MSP430F5222IRGZT implements a true dual-supply architecture: DVCC (1.8–3.6 V) powers the core, analog peripherals (ADC, comparator), and AVCC; DVIO (1.62–1.98 V) powers all general-purpose digital I/O ports (P1–P7, PJ). This allows direct interfacing with 1.8-V logic and sensors without external level translators - verified by Schmitt-trigger inputs and full-drive-strength outputs on the DVIO rail.
