Product details
Overview
MSP430F5308IPTR 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/I²C/SPI), 10-bit ADC with 12 channels (10 external + 2 internal), and integrated RTC. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and digital timers.
For engineers reviewing the MSP430F5308IPTR datasheet, MSP430F5308IPTR pinout, MSP430F5308IPTR application, or MSP430F5308IPTR equivalent, key selection criteria include standby current (1.9 µA at 3 V), wake-up time (<5 µs), 48-pin LQFP package compatibility, and dual-USCI interface flexibility for UART/I²C coexistence in space-constrained designs.
Technical Context
The MSP430F5308IPTR implements a unified clock system (UCS) with FLL-based frequency stabilization, programmable LDO core regulation, and multiple low-power modes (LPM3/LPM4/LPM4.5). Its CPUXV2 core supports 16-bit RISC execution up to 25 MHz with constant generators for optimized code density.
Peripheral integration includes hardware multiplier for 32-bit operations, 3-channel DMA, comparator_B, and port mapping controller on P4 enabling dynamic reconfiguration of USCI_A1/USCI_B1 signals-critical for routing UART and I²C simultaneously within the 48-pin LQFP footprint.

Does the MSP430F5308IPTR support crystal oscillators for both low- and high-frequency operation?
Yes, the MSP430F5308IPTR supports dual crystal oscillators: a 32-kHz watch crystal (XT1) for RTC and low-frequency timing, and a high-frequency crystal up to 32 MHz (XT2) for system clock generation. Both are explicitly supported in the functional block diagram and electrical specifications of the MSP430F5308IPTR datasheet.
How many USCI modules does the MSP430F5308IPTR integrate, and what protocols do they support?
The MSP430F5308IPTR integrates two universal serial communication interfaces (USCI_A0/USCI_A1 and USCI_B0/USCI_B1), supporting UART, IrDA, SPI, and I²C protocols. Each USCI can be independently configured-USCI_A for asynchronous UART/IrDA or synchronous SPI, and USCI_B for I²C or SPI-as verified in the device overview and functional block diagrams for MSP430F5308IPTR.
What is the ADC resolution and channel count for the MSP430F5308IPTR?
The MSP430F5308IPTR features a 10-bit successive approximation register (SAR) ADC (ADC10_A) with 12 total input channels: 10 external analog inputs (A0–A9) and 2 internal sources (VeREF+ and VeREF−). This configuration is documented in Table 3-1 and Section 5.34 of the MSP430F5308IPTR datasheet.
Is the MSP430F5308IPTR pin-compatible with other members of the MSP430F53xx family in the same package?
Yes, the MSP430F5308IPTR is pin-compatible with MSP430F5309IPTR and MSP430F5304IPTR in the 48-pin LQFP (PT) and VQFN (RGZ) packages.
