Product details
Overview
MSP430F5217IRGCT from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 64 KB flash, 8 KB RAM, dual-supply operation (DVCC/DVIO), three 16-bit timers (TA0/TA1/TA2 and TB0), two USCI modules (UART/IrDA/SPI/I²C), RTC, hardware multiplier, DMA, and comparator. It targets battery-powered sensor nodes and portable data loggers requiring sub-2 µA standby current and fast 3.5 µs wake-up.
For engineers reviewing the MSP430F5217IRGCT datasheet, MSP430F5217IRGCT pinout, MSP430F5217IRGCT application, or MSP430F5217IRGCT equivalent, key selection criteria include DVIO-compatible I/O (1.62–1.98 V), LPM3 current (1.9 µA at 2.2 V), 64-pin VQFN package, absence of integrated ADC, and timer configuration (5+3+3 TA registers + 7 TB registers).
Technical Context
The MSP430F5217IRGCT implements a split-rail I/O architecture with DVCC (1.8–3.6 V) and DVIO (1.62–1.98 V) supplies, enabling direct interface to 1.8-V peripherals without level shifters. Its unified clock system integrates FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz) sources for flexible timing control across power modes.
It executes in Active Mode at 290 µA/MHz (8 MHz, 3.0 V, flash) and enters Standby (LPM3) with RTC active at 1.9 µA (2.2 V) or Off (LPM4) at 1.1 µA (3.0 V), supported by programmable LDO core regulation and brownout detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with constant generators and 25-MHz max system clock |
| Memory | 64 KB flash + 8 KB RAM - sufficient for firmware with real-time sensor processing and RTC alarm handling |
| Power Modes | LPM3: 1.9 µA @ 2.2 V with RTC/crystal; LPM4: 1.1 µA @ 3.0 V - enables multi-year battery life in sleep-dominated applications |
| Timers | Three Timer_A instances (5/3/3 capture/compare registers) + one Timer_B (7 registers) - supports complex PWM, input capture, and RTC synchronization |

FAQ
What is the maximum operating frequency of the MSP430F5217IRGCT?
The MSP430F5217IRGCT 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 deterministic real-time execution for time-critical sensor sampling and communication protocols while maintaining ultra-low power consumption in active mode.
Does the MSP430F5217IRGCT include an analog-to-digital converter (ADC)?
No, the MSP430F5217IRGCT does not include an integrated ADC. It belongs to the MSP430F521x series, which omits the ADC10_A module present in the F522x variants. Designers must use external ADCs or select MSP430F5227IRGCT if on-chip 10-bit conversion is required.
What package type and dimensions does the MSP430F5217IRGCT use?
The MSP430F5217IRGCT uses a 64-pin VQFN (RGC) package with a 9 mm × 9 mm body size and an exposed thermal pad. TI recommends connecting the thermal pad to DVSS for optimal thermal performance and electrical stability in high-reliability applications.
How many general-purpose I/O pins does the MSP430F5217IRGCT support?
The MSP430F5217IRGCT provides up to 22 I/O pins supplied by DVCC (1.8–3.6 V) and up to 31 I/O pins supplied by DVIO (1.62–1.98 V), totaling 53 configurable GPIOs. Pin mapping is fully programmable via port control registers, with interrupt capability on all DVCC- and DVIO-domain pins.
What low-power modes are available on the MSP430F5217IRGCT and their typical currents?
The MSP430F5217IRGCT supports LPM3 (1.9 µA @ 2.2 V with RTC), LPM4 (1.1 µA @ 3.0 V), and LPM4.5 (0.18 µA @ 3.0 V). These modes retain full RAM content and support fast wake-up, making them ideal for applications requiring long idle periods with periodic RTC-triggered activity.
