Overview
MSP430F5309IRGCR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 24 KB flash, 6 KB RAM, integrated 3.3-V LDO, four 16-bit timers (TA0/TA1/TA2/TB0), dual USCI modules (UART/IrDA/SPI/I²C), 10-bit ADC with window comparator, RTC, hardware multiplier, and 31 I/O pins in a 64-pin VQFN package. It targets battery-powered sensor systems and digital timers requiring sub-2 µA standby current.
For engineers reviewing the MSP430F5309IRGCR datasheet, MSP430F5309IRGCR pinout, MSP430F5309IRGCR application, or MSP430F5309IRGCR equivalent, key selection criteria include LPM3 current (1.9 µA @ 2.2 V), 10-bit ADC channel count (10 external + 2 internal), dual USCI support, 47 I/O capability in RGC package, and RTC alarm functionality with crystal oscillator interface.
Technical Context
The MSP430F5309IRGCR implements a unified clock system (UCS) with FLL stabilization, VLO and REFO internal sources, and support for both 32-kHz XT1 and up to 32-MHz XT2 crystals.

FAQ
What is the maximum system clock frequency supported by the MSP430F5309IRGCR?
The MSP430F5309IRGCR supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) stabilized by the FLL loop within the Unified Clock System. This frequency is confirmed in the device description and functional block diagrams, and enables high-speed instruction execution while maintaining ultra-low-power operation in active mode.
Does the MSP430F5309IRGCR support crystal oscillators for both low- and high-frequency operation?
Yes, the MSP430F5309IRGCR supports both low-frequency (32-kHz) watch crystals via XT1 and high-frequency crystals up to 32 MHz via XT2. The XT1 pins (P5.4/XIN and P5.5/XOUT) are dedicated to 32-kHz crystals for RTC operation, while XT2 pins (P5.2/XT2IN and P5.3/XT2OUT) accept higher-frequency crystals for system clock derivation - all explicitly documented in Section 1.3 and Figure 1-1.
How many I/O pins does the MSP430F5309IRGCR provide in the RGC package?
The MSP430F5309IRGCR in the 64-pin VQFN (RGC) package provides 47 general-purpose I/O pins, as specified in Table 3-1 (Device Comparison) and confirmed in the functional block diagram for RGC/ZXH/ZQE packages. This includes all port pins except power, ground, and dedicated analog/digital supply terminals.
Is the MSP430F5309IRGCR pin-compatible with other devices in the MSP430F53xx family?
Yes, the MSP430F5309IRGCR shares identical pinouts with MSP430F5310IRGCR and MSP430F5308IRGCR in the RGC package, as shown in Figure 4-1 and verified in Table 3-1. All three devices use the same 64-pin VQFN footprint, signal assignments, and electrical characteristics - enabling drop-in replacement within this variant group.
What is the role of the port mapping controller in the MSP430F5309IRGCR?
The port mapping controller in the MSP430F5309IRGCR enables dynamic assignment of USCI_A1 and USCI_B1 secondary functions to Port 4 pins (P4.0–P4.4). This allows flexible routing of UART, SPI, or I²C signals without fixed pin constraints - critical for board layout optimization and multi-protocol design, as detailed in Section 1.3 and Table 4-1.
