Product details
Overview
MSP430F5308IRGCT 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 12 channels (10 external + 2 internal), 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 MSP430F5308IRGCT datasheet, MSP430F5308IRGCT pinout, MSP430F5308IRGCT application, or MSP430F5308IRGCT equivalent, key selection criteria include LPM3 current (1.9 µA @ 2.2 V), 47 I/O count in RGC package, dual-USCI flexibility, 200 kSPS ADC sampling rate, and integrated 3.3-V LDO with programmable core voltage regulation.
Technical Context
The MSP430F5308IRGCT 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 a flexible power-management system with supply supervision and brownout detection.
Peripherals are accessed via port mapping controllers (e.g., P4 configurable for USCI_B1 and USCI_A1 functions), enabling runtime reassignment of secondary functions without hardware changes. The device uses CPUXV2 core architecture with constant generators for optimized code efficiency and sub-5-µs wake-up from standby mode.

FAQ
What is the maximum operating frequency of the MSP430F5308IRGCT?
The MSP430F5308IRGCT supports a maximum system clock frequency of 25 MHz, enabled by its digitally controlled oscillator (DCO) and FLL-based unified clock system. This allows high-speed instruction execution while maintaining ultra-low power consumption in active mode (195 µA/MHz typical at 8 MHz, 3 V). The device achieves this performance without external high-frequency crystals, though XT2 supports up to 32 MHz for specialized timing requirements.
Does the MSP430F5308IRGCT support hardware debugging during development?
Yes, the MSP430F5308IRGCT supports full hardware debugging via Spy-Bi-Wire (SBW) using the RST/NMI/SBWTDIO and TEST/SBWTCK pins. This 2-wire interface enables flash programming, real-time breakpoint setting, register inspection, and step-through execution-eliminating the need for dedicated JTAG pins and reducing PCB footprint. SBW is fully supported by TI's Code Composer Studio and MSP430 Flash Emulation Tool (FET).
How many analog input channels does the ADC support on the MSP430F5308IRGCT?
The MSP430F5308IRGCT integrates a 10-bit ADC (ADC10_A) with 12 total input channels: 10 external analog inputs (A0–A9) and 2 internal references (VeREF+ and VeREF−). Channel selection is software-configurable, and the ADC supports window comparator functionality for autonomous threshold detection without CPU intervention-ideal for battery voltage monitoring or sensor fault detection.
Can the MSP430F5308IRGCT operate from a single 2.0-V battery?
Yes, the MSP430F5308IRGCT is fully specified to operate across 1.8 V to 3.6 V, making it compatible with a single 2.0-V alkaline or NiMH cell. Its integrated LDO maintains stable 3.3-V core and I/O supply down to 1.8 V input, and low-power modes (e.g., LPM3 at 1.9 µA @ 2.2 V) ensure viable runtime even as battery voltage declines-critical for long-life portable instrumentation.
Is the MSP430F5308IRGCT pin-compatible with other devices in the MSP430F53xx family?
Yes, the MSP430F5308IRGCT in the 64-pin RGC package shares identical pinout and electrical characteristics with MSP430F5310IRGCT and MSP430F5309IRGCT. All three devices support the same peripheral mappings, voltage ratings, and timing specifications-enabling direct substitution in existing designs for memory scaling (8 KB → 16 KB → 24 KB → 32 KB) without PCB revision.
