Product details
Overview
MSP430F5522IRGCR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, 12-bit ADC (12-channel), four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), RTC, hardware multiplier, and 3-channel DMA. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and USB-connected data loggers.
For engineers reviewing the MSP430F5522IRGCR datasheet, MSP430F5522IRGCR pinout, MSP430F5522IRGCR application, or MSP430F5522IRGCR equivalent, key selection criteria include its 47 GPIO count, RGC64 package footprint, USB-capable active-mode current (290 µA/MHz @ 8 MHz), LPM3 standby current (1.9 µA @ 3.0 V), and 64 KB flash / 8 KB + 2 KB RAM memory configuration.
Technical Context
The MSP430F5522IRGCR implements a 16-bit RISC CPUXV2 core with constant generators and unified clock system featuring FLL stabilization, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power architecture includes an integrated LDO with programmable core voltage, SVS/SVM supervision, and brownout reset.
Peripherals are organized around three USCI modules (USCI_A0/A1/B0/B1), full-speed USB 2.0 interface with dedicated USB-LDO and USB-PLL, 12-bit ADC12_A with autoscan and internal reference, and Timer_B0 with seven capture/compare shadow registers - all mapped to 47 I/O pins in the RGC64 package.

FAQ
What is the maximum operating frequency of the MSP430F5522IRGCR?
The MSP430F5522IRGCR supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This frequency ensures full compliance with USB 2.0 full-speed timing requirements and enables real-time execution of sensor fusion algorithms without external clock sources.
Does the MSP430F5522IRGCR include an integrated USB transceiver?
Yes, the MSP430F5522IRGCR integrates a full-speed USB 2.0 PHY, USB-PLL, and dual-voltage USB power system (3.3 V and 1.8 V). This eliminates the need for external USB transceivers, level shifters, or dedicated USB LDOs - reducing BOM count and PCB area while maintaining USB electrical compliance.
How many analog input channels does the ADC support on the MSP430F5522IRGCR?
The MSP430F5522IRGCR features a 12-bit ADC12_A module with 12 total input channels: 10 external analog inputs (P6.0–P6.7, P7.0–P7.1) and 2 internal sources (temperature sensor and VREF generator). Channel selection is fully programmable via ADC12MCTLx registers and supports autoscan sequencing.
What low-power modes are supported by the MSP430F5522IRGCR?
The MSP430F5522IRGCR supports five low-power modes: LPM0–LPM3 with varying peripheral activity, plus LPM4.5 (shutdown). In LPM3, it draws just 1.9 µA at 3.0 V with RTC, watchdog, and full RAM retention - enabling multi-year operation on standard coin-cell batteries in always-on sensor applications.
Is the MSP430F5522IRGCR pin-compatible with other devices in the MSP430F55xx family?
Yes, the MSP430F5522IRGCR in the RGC64 package shares identical pinout and signal mapping with MSP430F5524IRGC, MSP430F5526IRGC, and MSP430F5528IRGC. This allows direct substitution within the same PCB footprint when memory or peripheral requirements change - no layout revision needed.
