Product details
Overview
MSP430F5522IRGCT 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, 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 delivers 290 µA/MHz active current at 8 MHz (flash execution), targeting battery-powered sensor nodes and USB-connected data loggers.
For engineers reviewing the MSP430F5522IRGCT datasheet, MSP430F5522IRGCT pinout, MSP430F5522IRGCT application, or MSP430F5522IRGCT equivalent, key selection criteria include its 47 I/O count, VQFN-64 package, USB-capable architecture, low-power LPM3/LPM4 modes (1.9 µA / 1.1 µA), and ADC channel count versus higher-pin-count F5529 variants.
Technical Context
The MSP430F5522IRGCT implements a 16-bit RISC CPU with extended memory addressing, digitally controlled oscillator (DCO), and unified clock system featuring FLL stabilization, REFO, VLO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management includes an integrated LDO with programmable core voltage and supply supervision.
It integrates full-speed USB 2.0 via on-die PHY, USB-PLL, dual 3.3-V/1.8-V USB power system, and eight endpoints - enabling direct host connectivity without external transceivers. The 12-bit ADC supports autoscan across 10 external + 2 internal channels at up to 200 ksps with internal reference and sample-and-hold.

FAQ
What is the maximum operating frequency of the MSP430F5522IRGCT?
The MSP430F5522IRGCT supports a maximum system clock frequency of 25 MHz, achieved via the integrated FLL stabilizing the DCO against XT2 (up to 32 MHz crystal) or internal references. This enables high-speed USB frame handling and efficient execution of real-time sensor algorithms within the MSP430F5522IRGCT's ultra-low-power architecture.
Does the MSP430F5522IRGCT support USB device enumeration without external components?
Yes, the MSP430F5522IRGCT integrates a full-speed USB 2.0 PHY, USB-PLL, and dual 3.3-V/1.8-V USB power system - allowing complete USB device enumeration and communication using only passive termination resistors and the DP/DM lines. No external transceiver or voltage translator is required for standard USB connections.
How many analog input channels does the MSP430F5522IRGCT ADC support?
The MSP430F5522IRGCT features a 12-bit ADC (ADC12_A) with support for 12 total channels: 10 external analog inputs (P1.0–P1.7, P2.0–P2.1) and 2 internal sources (temperature sensor and VREF generator). This configuration is confirmed in the functional block diagram (Figure 4-2) and electrical specifications (Section 8.35–8.39) of the MSP430F5522IRGCT datasheet.
What low-power modes are available on the MSP430F5522IRGCT, and what is the lowest current draw?
The MSP430F5522IRGCT supports five low-power modes (LPM0–LPM4.5). The lowest active-retention mode is LPM4.5, drawing 0.18 µA at 3.0 V with full RAM retention and supply supervisor enabled. LPM3 (RTC active) draws 1.9 µA at 3.0 V - both values are measured and specified in Section 8.5 of the MSP430F5522IRGCT datasheet.
Is the MSP430F5522IRGCT pin-compatible with other devices in the MSP430F55xx family?
The MSP430F5522IRGCT shares the same 64-pin VQFN (RGC) package and pinout with MSP430F5528IRGC, MSP430F5526IRGC, and MSP430F5524IRGC - enabling direct PCB reuse across these variants. However, it is not pin-compatible with 80-pin LQFP (e.g., MSP430F5529IPN) or different-package variants like ZQE or YFF.
