Product details
Overview
MSP430F5310IRGCT from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 32 KB Flash, 6 KB RAM, dual USCI modules (UART/IrDA/SPI/I²C), 10-bit 200 kSPS ADC with window comparator, RTC, four 16-bit timers (TA0/TA1/TA2/TB0), hardware multiplier, and integrated 3.3-V LDO. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems requiring sub-2 µA standby current and <5 µs wake-up.
For engineers reviewing the MSP430F5310IRGCT datasheet, MSP430F5310IRGCT pinout, MSP430F5310IRGCT application, or MSP430F5310IRGCT equivalent, key selection criteria include its 48-pin VQFN (RGCT) package, 47 I/O pins, dual-USCI flexibility for concurrent serial protocols, and verified low-power operation down to 1.1 µA in LPM4 mode - critical for portable metering and timer applications.
Technical Context
The MSP430F5310IRGCT implements a 16-bit RISC CPUXV2 core with constant generators and unified clock system (UCS) supporting FLL-stabilized MCLK up to 25 MHz, REFO (32.768 kHz), VLO (10 kHz), XT1 (32 kHz crystal), and XT2 (up to 32 MHz crystal). Its power management includes programmable LDO core regulation, SVM/SVS brownout detection, and five low-power modes (LPM0–LPM4.5).
Peripherals are mapped via port mapping controller (P4), enabling dynamic reconfiguration of USCI signals on port 4 pins. The device integrates 3-channel DMA, CRC16 engine, and EEM (enhanced embedded memory) for efficient Flash programming - all optimized for deterministic real-time response in measurement-critical embedded control.

FAQ
What is the maximum system clock frequency supported by the MSP430F5310IRGCT?
The MSP430F5310IRGCT supports a maximum system clock (MCLK) frequency of 25 MHz, achieved via its integrated FLL control loop using XT2 (up to 32 MHz crystal) or internal DCO. This is confirmed in Section 1.1 Features and Figure 1-1 of the SLAS677F datasheet. The MSP430F5310IRGCT delivers deterministic real-time performance while maintaining ultra-low active-mode current of 195 µA/MHz at 8 MHz and 3 V.
Does the MSP430F5310IRGCT support crystal oscillators for both low-frequency and high-frequency operation?
Yes, the MSP430F5310IRGCT supports dual crystal oscillators: XT1 accepts a 32.768 kHz watch crystal for RTC and ACLK generation, while XT2 supports crystals up to 32 MHz for high-speed MCLK/SMCLK. Pin assignments P5.4/XIN and P5.5/XOUT are dedicated to XT1; XT2 uses P5.2/XT2IN and P5.3/XT2OUT. This dual-crystal capability is explicitly documented in the Functional Block Diagram (Figure 1-2) and Section 5.14–5.15 of the SLAS677F datasheet.
How many I/O pins does the MSP430F5310IRGCT provide in its VQFN-48 (RGCT) package?
The MSP430F5310IRGCT in the 48-pin VQFN (RGCT) package provides 47 general-purpose I/O pins, as confirmed in Table 3-1 (Device Comparison) and Section 1.3 Description of the SLAS677F datasheet. This includes all port pins (P1–P6, PU, PJ) except power, ground, and dedicated debug pins (RST/NMI, TEST/SBWTCK, TCK/TMS/TDI/TDO), which are counted separately.
What are the low-power mode current specifications for the MSP430F5310IRGCT?
The MSP430F5310IRGCT achieves 1.9 µA in LPM3 (RTC active, full RAM retention), 1.1 µA in LPM4 (off mode), and 0.18 µA in LPM4.5 (shutdown mode) - all at 3 V, per Section 1.1 Features and Section 5.5 of SLAS677F. These values are measured with integrated LDO enabled and exclude external circuitry, enabling multi-year battery life in always-on applications.
Can the MSP430F5310IRGCT simultaneously operate UART and I²C interfaces?
Yes, the MSP430F5310IRGCT integrates two independent USCI modules (USCI_A0/A1 and USCI_B0/B1), allowing concurrent UART and I²C operation. Section 1.1 confirms "Two Universal Serial Communication Interfaces (USCIs)" with separate A- and B-type functionality. Pin mapping on Port 4 (P4.0–P4.4) supports dynamic assignment of UCA1TXD/UCA1RXD and UCB1SCL/UCB1SDA, enabling true hardware-level protocol isolation without software arbitration.
