Product details
Overview
MSP430F5308IRGZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 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 external channels, RTC, hardware multiplier, and 3-channel DMA. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and digital timers.
For engineers reviewing the MSP430F5308IRGZR datasheet, MSP430F5308IRGZR pinout, MSP430F5308IRGZR application, or MSP430F5308IRGZR equivalent, key selection criteria include LPM3 current (1.9 µA @ 2.2 V), 48-pin VQFN package footprint, dual-USCI interface flexibility, 10-bit ADC resolution with window comparator, and RTC alarm capability in low-power operation.
Technical Context
The MSP430F5308IRGZR implements a unified clock system (UCS) with FLL stabilization, VLO and REFO internal sources, and support for 32-kHz XT1 and up to 32-MHz XT2 crystals. Its five low-power modes-including LPM4.5 (0.18 µA shutdown)-are managed by an integrated LDO with programmable core voltage and supply supervision.
Peripherals are mapped via port mapping controller on Port 4, enabling dynamic reconfiguration of USCI_A1 and USCI_B1 functions (e.g., UART, I²C, SPI). The device includes Schmitt-trigger inputs on all general-purpose I/O pins and supports wake-up from standby in <5 µs.

FAQ
What is the maximum operating frequency of the MSP430F5308IRGZR?
The MSP430F5308IRGZR supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This frequency is validated across the full 1.8 V to 3.6 V supply range and specified in the recommended operating conditions table of the SLAS677G datasheet. The device maintains timing integrity at this rate while delivering 195 µA/MHz active-mode current at 3 V.
Does the MSP430F5308IRGZR support crystal oscillators?
Yes, the MSP430F5308IRGZR supports two crystal oscillator circuits: a low-frequency 32-kHz watch crystal (XT1) on P5.4/XIN and P5.5/XOUT, and a high-frequency crystal up to 32 MHz (XT2) on P5.2/XT2IN and P5.3/XT2OUT. Both are fully integrated into the unified clock system and can serve as FLL reference sources or direct clock inputs for peripherals.
How many I/O pins does the MSP430F5308IRGZR have in the RGZ package?
The MSP430F5308IRGZR in the 48-pin VQFN (RGZ) package provides 31 general-purpose I/O pins. This count excludes power, ground, reset, debug, and dedicated analog inputs (e.g., VeREF±), and aligns with the device comparison table in SLAS677G. All 31 pins support interrupt capability and Schmitt-trigger inputs.
Can the MSP430F5308IRGZR operate from a single 3.3-V supply?
Yes, the MSP430F5308IRGZR integrates a 3.3-V LDO regulator and is rated for operation from 1.8 V to 3.6 V. When powered from a nominal 3.3-V source, the internal LDO delivers regulated core voltage and powers analog/digital domains. No external regulator is required, simplifying power design for compact, low-component-count applications.
Is the MSP430F5308IRGZR pin-compatible with other devices in the F530x family?
Yes, the MSP430F5308IRGZR shares identical pinout and package dimensions with MSP430F5304IRGZR, MSP430F5309IRGZR, and MSP430F5310IRGZR in the 48-pin VQFN (RGZ) package. All four devices use the same signal mapping on each pin, enabling drop-in replacement within the same package variant-subject to firmware compatibility with memory size differences.
