Product details
Overview
MSP430F5227IRGCT from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 64 KB Flash, 8 KB RAM, dual-supply I/O (DVCC/DVIO), 10-bit ADC with 10 external channels, two USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers, RTC, hardware multiplier, and DMA - deployed in battery-powered sensor nodes and data loggers.
For engineers reviewing the MSP430F5227IRGCT datasheet, MSP430F5227IRGCT pinout, MSP430F5227IRGCT application, or MSP430F5227IRGCT equivalent, key selection criteria include LPM3 current (1.9 µA), dual-voltage I/O support (1.62–1.98 V DVIO), 64-pin VQFN package, RTC alarm capability, and ADC sample rate (200 kSPS) for precision analog sensing.
Technical Context
The MSP430F5227IRGCT implements a CPUXV2 16-bit RISC core with constant generators and extended memory addressing, paired with a unified clock system including FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management includes an integrated LDO with programmable VCORE and supply supervision (SVM/SVS).
Peripherals are organized across two voltage domains: DVCC-supplied I/O (P1.0–P1.3, P5–P6, PJ) and DVIO-supplied I/O (P1.4–P1.7, P2–P4, P7), enabling direct interface to 1.8-V logic without level shifters. All timers (TA0/TA1/TA2/TB0) support capture/compare and PWM, with TB0 offering shadow registers for glitch-free updates.

FAQ
What is the maximum operating frequency of the MSP430F5227IRGCT?
The MSP430F5227IRGCT supports a maximum system clock (MCLK) frequency of 25 MHz, achieved via the FLL-controlled DCO using XT2 (up to 32 MHz crystal) or internal REFO/VLO references. This enables high-speed computation while retaining ultra-low-power operation in active mode (290 µA/MHz at 8 MHz, 3.0 V).
Does the MSP430F5227IRGCT support crystal oscillators for both low- and high-frequency operation?
Yes, the MSP430F5227IRGCT supports dual crystal oscillators: XT1 accepts 32.768-kHz watch crystals for RTC and ACLK generation, while XT2 supports high-frequency crystals up to 32 MHz for MCLK/SMCLK. Both are fully integrated with automatic gain control and fault detection circuitry.
How many external interrupt-capable pins does the MSP430F5227IRGCT have?
The MSP430F5227IRGCT provides up to 12 external interrupt-capable pins - all DVIO-supplied I/O (P1.4–P1.7, P2.0–P2.7) and selected DVCC-supplied I/O (P1.0–P1.3, PJ.0–PJ.3) support configurable edge-triggered interrupts, enabling responsive wake-up from LPM3/LPM4 modes.
Can the MSP430F5227IRGCT operate with different supply voltages for core and I/O?
Yes, the MSP430F5227IRGCT uses a split-supply architecture: DVCC (1.8–3.6 V) powers the core and DVCC-domain I/O, while DVIO (1.62–1.98 V) independently powers DVIO-domain I/O. This allows seamless interfacing with 1.8-V peripherals without external level translation.
Is the MSP430F5227IRGCT pin-compatible with other devices in the MSP430F52xx family?
Yes, the MSP430F5227IRGCT in the 64-pin RGC package shares identical pinout and electrical characteristics with MSP430F5229IRGCT, MSP430F5217IRGCT, and MSP430F5219IRGCT - enabling hardware reuse across variants differing only in Flash size or ADC inclusion.
