Texas Instruments MSP430F5513IRGCT

Overview

MSP430F5513IRGCT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), RTC, hardware multiplier, and 3-channel DMA. It operates from 1.8 V to 3.6 V, draws 1.4 µA in LPM3 standby with VLO active, and wakes in 3.5 µs-ideal for battery-powered USB-connected sensor nodes and portable data loggers.

For engineers reviewing the MSP430F5513IRGCT datasheet, MSP430F5513IRGCT pinout, MSP430F5513IRGCT application, or MSP430F5513IRGCT equivalent, key selection criteria include its 47 I/O count, 32 KB Flash / 4 KB + 2 KB RAM memory map, VQFN-64 package, USB-capable peripheral set, and verified low-power mode current specs across LPM3/LPM4/LPM4.5.

Technical Context

The MSP430F5513IRGCT implements a 16-bit RISC CPUXV2 core with constant generators and unified clock system featuring FLL stabilization, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management includes an integrated LDO with programmable core voltage, SVS/SVM monitoring, and brownout reset.

Peripherals are mapped via port-select registers and support flexible signal routing: USCI_A0/A1 provide UART/IrDA/SPI; USCI_B0/B1 support I²C/SPI; USB module integrates PHY, PLL, 3.3-V/1.8-V power system, and eight endpoints; Timer_B0 offers seven capture/compare shadow registers for precise PWM and event timing.

FAQ

What is the maximum system clock frequency supported by the MSP430F5513IRGCT?

The MSP430F5513IRGCT supports a maximum system clock frequency of 25 MHz, achieved via the FLL locking the DCO to high-frequency sources such as XT2 (up to 32 MHz crystal or external clock). This frequency is validated across the full operating voltage range (1.8 V to 3.6 V) and ambient temperature range (–40°C to 85°C), enabling deterministic real-time execution for time-critical USB and sensor tasks in the MSP430F5513IRGCT.

Does the MSP430F5513IRGCT include an analog-to-digital converter (ADC)?

No, the MSP430F5513IRGCT does not include an ADC. Unlike the MSP430F552x series, the MSP430F551x family-including the MSP430F5513IRGCT-omits the 12-bit ADC12_A module. This is confirmed in the device comparison tables and functional block diagrams (Figure 4-4), which show no ADC block for RGC-packaged MSP430F5513IRGCT. Designers requiring analog sensing must select an alternative part such as MSP430F5529IPN.

What USB speed and compliance level does the MSP430F5513IRGCT support?

The MSP430F5513IRGCT supports full-speed USB 2.0 (12 Mbps) with integrated PHY, meeting USB 2.0 specification requirements for device-side operation. It implements all necessary electrical signaling, endpoint management (eight total: four IN, four OUT), and protocol handling-including suspend/resume, SOF tracking, and descriptor responses-without external components. The MSP430F5513IRGCT's USB subsystem is fully compliant when used with TI's recommended layout and termination.

How many general-purpose I/O pins does the MSP430F5513IRGCT provide?

The MSP430F5513IRGCT provides 47 general-purpose I/O pins, as specified in the device description and confirmed in Figure 4-4 (functional block diagram) and Section 7 (Terminal Configuration). These are distributed across Ports P1–P6 with configurable pullup/pulldown, drive strength, and interrupt capability. This I/O count is consistent across all RGC-packaged MSP430F551x variants, including the MSP430F5513IRGCT.

What low-power modes are available on the MSP430F5513IRGCT, and what is the lowest current draw?

The MSP430F5513IRGCT supports five low-power modes: LPM0–LPM4 plus LPM4.5. The lowest operational current is 0.18 µA in LPM4.5 (shutdown mode) at 3.0 V, with full RAM retention and supply supervisor active. In LPM3 (real-time clock mode with VLO), it draws 1.4 µA at 3.0 V-enabling years of operation on small batteries. All values are measured and published in Section 8.5 of the official datasheet for the MSP430F5513IRGCT.
