Product details
Overview
MSP430F5308IPT 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 channels (6 external + 2 internal), RTC, hardware multiplier, and 31 GPIOs in a 48-pin LQFP package. It targets battery-powered sensor systems and digital timers requiring sub-2 µA standby current.
For engineers reviewing the MSP430F5308IPT datasheet, MSP430F5308IPT pinout, MSP430F5308IPT application, or MSP430F5308IPT equivalent, key selection criteria include its 1.8–3.6 V supply range, <5 µs wake-up from LPM3, integrated 3.3-V LDO, port mapping controller for flexible USCI routing on P4, and RTC alarm capability with crystal support.
Technical Context
The MSP430F5308IPT implements a 16-bit RISC CPU with constant generators and extended memory addressing, paired with a unified clock system (UCS) including FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management includes programmable core voltage regulation via an integrated LDO and five low-power modes (AM, LPM0–LPM4.5).
Peripherals are organized around three-channel DMA, hardware multiplier supporting 32-bit operations, and dual USCI modules-USCI_A1 and USCI_B1-mapped exclusively to Port 4 via the port mapping controller, limiting simultaneous signal availability per configuration. The 10-bit ADC supports window comparator and up to 200 kSPS sampling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Flash Memory | 16 KB - Stores firmware with in-system programming; sufficient for sensor node firmware with RTOS or protocol stacks. |
| RAM | 6 KB - Supports real-time data buffering, stack depth for nested interrupts, and small heap allocations. |
| Supply Voltage | 1.8 V to 3.6 V - Enables direct operation from single Li-ion, two alkaline, or regulated 3.3-V rails without external level shifting. |
| Standby Current (LPM3) | 1.9 µA at 2.2 V - Enables multi-year battery life in RTC-critical applications like thermostats or utility meters. |
| Wake-up Time | <5 µs from LPM3 - Meets fast-response requirements in motor control fault detection or wake-on-event sensor hubs. |
| ADC Resolution & Channels | 10-bit, 8 channels (6 external + 2 internal) - Supports simultaneous analog sensing of temperature, voltage, and reference monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5309IPT | 24 KB flash, same RAM, peripherals, and pinout; higher program storage for larger firmware or bootloader + app partitioning. | Better suited for applications requiring field-upgradable firmware or integrated USB communication stacks. | Select when firmware size exceeds 16 KB but identical peripheral count and power profile are required. |
| MSP430F5304IPT | 8 KB flash, single USCI (USCI_A0 only), 31 GPIOs; lacks USCI_B0 and second USCI instance. | Targeted at cost-sensitive, single-interface designs such as basic timers or simple sensor loggers without I²C/SPI master capability. | Choose for lowest BOM cost where dual-USCI functionality is unnecessary and flash demand is under 8 KB. |
Compared with MSP430F5304IPT, the MSP430F5308IPT adds a second USCI module and doubles flash capacity-enabling richer connectivity and firmware features without changing PCB layout. Against MSP430F5309IPT, it trades 8 KB flash for lower unit cost while retaining identical peripheral sets and power performance.

FAQ
What is the maximum system clock frequency supported by the MSP430F5308IPT?
The MSP430F5308IPT supports a maximum system clock frequency of 25 MHz, achieved via the FLL-controlled DCO or external high-frequency crystals up to 32 MHz on XT2. This enables high-speed ADC sampling (200 kSPS), fast interrupt response, and efficient execution of real-time control algorithms within the 16-bit RISC architecture.
Does the MSP430F5308IPT support crystal oscillators for both low- and high-frequency operation?
Yes, the MSP430F5308IPT supports dual crystal oscillators: a 32-kHz watch crystal on XT1 for RTC and low-power timing, and a high-frequency crystal up to 32 MHz on XT2 for system clock generation. Both are fully integrated into the Unified Clock System (UCS) with automatic fail-safe switching and FLL stabilization.
How many USCI modules does the MSP430F5308IPT include, and how are they routed?
The MSP430F5308IPT includes two USCI modules: USCI_A1 and USCI_B1. Unlike fixed-function pins, their signals are routed exclusively through Port 4 using the port mapping controller-allowing dynamic assignment of UART, SPI, or I²C functions to P4.0–P4.4, though not all signals can be active simultaneously.
What is the ADC configuration of the MSP430F5308IPT, and does it include internal references?
The MSP430F5308IPT integrates a 10-bit ADC (ADC10_A) with 8 input channels: 6 external analog inputs (A0–A5) and 2 internal sources (VeREF+ and VeREF−). It supports internal references (1.5 V and 2.5 V) and accepts external references via P5.0/P5.1, enabling ratiometric or precision absolute measurements without external reference ICs.
Is the MSP430F5308IPT pin-compatible with other devices in the MSP430F53xx family?
Yes, the MSP430F5308IPT in the 48-pin LQFP (PT) package shares identical pinout and electrical characteristics with MSP430F5309IPT and MSP430F5304IPT. This enables drop-in replacement across the family-software and hardware designs can scale flash capacity (8 KB → 16 KB → 24 KB) without layout changes.
