Product details
Overview
MSP430F5308IRGCR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 16 KB flash, 6 KB RAM, four 16-bit timers (TA0/TA1/TA2/TB0), dual USCI modules (UART/IrDA/SPI/I²C), 10-bit ADC with 8-channel input (6 external + 2 internal), RTC, hardware multiplier, and DMA. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and portable measurement devices.
For engineers reviewing the MSP430F5308IRGCR datasheet, MSP430F5308IRGCR pinout, MSP430F5308IRGCR application, or MSP430F5308IRGCR equivalent, key selection criteria include standby current (1.9 µA at 3 V), wake-up time (<5 µs), 47 I/O pins in 64-pin VQFN, dual USCI support, and integrated LDO for single-supply operation.
Technical Context
The MSP430F5308IRGCR implements a unified clock system (UCS) with FLL-based frequency stabilization, programmable LDO core regulation, and five low-power modes (LPM0–LPM4.5). Its CPUXV2 core executes instructions at up to 25 MHz with constant generators for optimized code efficiency.
Peripherals are managed via port mapping control on P4, enabling flexible USCI signal routing. The device integrates a 10-bit ADC with window comparator, Comparator_B, and RTC_A with alarm capability-each accessible without external components in typical embedded sensing configurations.

FAQ
What is the maximum operating frequency of the MSP430F5308IRGCR?
The MSP430F5308IRGCR supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This allows high-speed execution of time-critical tasks such as real-time ADC sampling, PWM generation, or communication protocol handling while maintaining ultra-low power consumption in active mode.
Does the MSP430F5308IRGCR support crystal oscillators?
Yes, the MSP430F5308IRGCR supports both low-frequency (32 kHz) watch crystals via XT1 (P5.4/XIN and P5.5/XOUT) and high-frequency crystals up to 32 MHz via XT2 (P5.2/XT2IN and P5.3/XT2OUT). These provide precise, low-jitter clock sources for RTC accuracy and high-speed peripheral operation.
How many I/O pins does the MSP430F5308IRGCR have in the RGC package?
The MSP430F5308IRGCR in the 64-pin VQFN (RGC) package provides 47 general-purpose I/O pins, as confirmed in TI's SLAS677G device comparison table. This includes all P1–P6, PJ, and PU ports with functional assignments defined in the pinout diagrams and signal descriptions.
Can the MSP430F5308IRGCR operate from a single 3.3-V supply?
Yes, the MSP430F5308IRGCR integrates a 3.3-V LDO power system that accepts input voltages from 1.8 V to 3.6 V and regulates internally to 3.3 V for core and I/O domains. This allows direct connection to standard 3.3-V rails or single-cell lithium batteries without external regulators.
Is the MSP430F5308IRGCR pin-compatible with other devices in the MSP430F53xx family?
Yes, the MSP430F5308IRGCR shares identical pinout, package dimensions, and peripheral mapping with MSP430F5309IRGCR and MSP430F5310IRGCR in the 64-pin RGC package. This enables drop-in replacement for memory-scaling upgrades without PCB redesign.
