Product details
Overview
MSP430F5222IRGZR 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), four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), hardware multiplier, DMA, RTC, and comparator. 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 MSP430F5222IRGZR datasheet, MSP430F5222IRGZR pinout, MSP430F5222IRGZR application, or MSP430F5222IRGZR equivalent, key selection criteria include its 48-pin VQFN (RGZ) package, split 3.6–1.8 V DVCC / 1.62–1.98 V DVIO supply rails, 20 DVCC-domain and 17 DVIO-domain I/Os, 200 kSPS ADC sampling rate, and LPM4.5 shutdown current of 0.18 µA at 3.0 V.
Technical Context
The MSP430F5222IRGZR implements a unified clock system with FLL stabilization, low-power 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 three independent Timer_A modules (5/3/3 capture/compare registers), one Timer_B (7 registers), dual USCI_A (UART/IrDA/SPI) and USCI_B (I²C/SPI), 10-bit ADC10_A with internal reference and sample-and-hold, and Comparator_B with 6 input channels - all operating under flexible low-power mode control with full RAM retention down to LPM4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with constant generators and 25-MHz max system clock for efficient code execution in resource-constrained embedded applications. |
| Memory | 64 KB Flash (in-system programmable, no external VPP) + 8 KB RAM with full retention in LPM3/LPM4 modes. |
| ADC | 10-bit ADC10_A with 200 kSPS sampling rate, 8 external + 2 internal analog inputs, and integrated reference for standalone sensor interfacing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5224IRGZ | Same RGZ package, identical peripherals and pinout, but with 128 KB Flash and 8 ext + 2 int ADC channels - no functional difference for MSP430F5222IRGZR use cases. | Preferred where future firmware expansion or larger data buffers are anticipated; otherwise pin- and code-compatible drop-in replacement. | Select MSP430F5224IRGZ if Flash headroom is required; otherwise MSP430F5222IRGZR optimizes cost for fixed-function deployments. |
| MSP430F5212IRGZ | Same RGZ package and I/O count, but lacks ADC10_A module - no analog input capability; otherwise matches timers, USCI, RTC, and power specs. | Suitable only for purely digital control or sensor systems using external ADC; cannot replace MSP430F5222IRGZR in ADC-dependent designs. | Choose MSP430F5212IRGZ only when analog sensing is handled externally; verify all ADC-dependent firmware paths are removed or redirected. |

FAQ
What is the maximum operating frequency of the MSP430F5222IRGZR?
The MSP430F5222IRGZR supports a maximum system clock frequency of 25 MHz, enabled by its digitally controlled oscillator (DCO) and FLL-based clock system. This allows high-speed instruction execution while maintaining ultra-low-power characteristics - verified in the SLAS718H datasheet Section 5.25 (DCO Frequency) under recommended operating conditions of 3.0 V and 25 °C.
Does the MSP430F5222IRGZR support crystal oscillators?
Yes, the MSP430F5222IRGZR supports both low-frequency (32 kHz) crystals via XT1 pins (P5.4/P5.5) and high-frequency crystals up to 32 MHz via XT2 pins (P5.2/P5.3). The device also includes internal VLO and REFO oscillators for clock redundancy and ultra-low-power operation - detailed in Sections 5.21–5.24 of the SLAS718H datasheet.
How many I/O pins does the MSP430F5222IRGZR have, and what are their voltage domains?
The MSP430F5222IRGZR provides 20 general-purpose I/Os powered by DVCC (1.8–3.6 V) and 17 I/Os powered by DVIO (1.62–1.98 V), totaling 37 usable GPIOs in its 48-pin RGZ package. Pin assignments and domain mapping are defined in Figure 4-2 and Table 4-2 of the SLAS718H datasheet.
Can the MSP430F5222IRGZR operate without an external crystal?
Yes, the MSP430F5222IRGZR can operate using its internal VLO (10 kHz typical) or trimmed REFO (32.768 kHz) oscillators - eliminating need for external crystals in applications where timing precision is secondary to power savings. Crystal-free operation is validated in LPM3 and active mode per Section 5.23–5.24 of SLAS718H.
What debug interface does the MSP430F5222IRGZR use?
The MSP430F5222IRGZR uses the Spy-Bi-Wire (SBW) interface via the RSTDVCC/SBWTDIO pin (Pin 46) and TEST/SBWTCK (Pin 19), requiring only two connections for full programming and debugging - compatible with TI's MSP-FET and LaunchPad development tools. JTAG is not supported on this device variant.
