Texas Instruments MSP430F5513IRGCR

Overview

MSP430F5513IRGCR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with USB 2.0 interface, integrated USB-PHY, USB-PLL, and USB-LDO; 64 KB flash, 4 KB + 2 KB RAM; 47 general-purpose I/O pins; and real-time clock (RTC) with alarm capability. It operates from 1.8 V to 3.6 V and targets battery-powered USB-connected sensor nodes and portable data loggers.

For engineers reviewing the MSP430F5513IRGCR datasheet, MSP430F5513IRGCR pinout, MSP430F5513IRGCR application, or MSP430F5513IRGCR equivalent, key selection criteria include USB 2.0 PHY integration, LPM4.5 shutdown current (0.18 µA), 3.5 µs wake-up from LPM3, 47-I/O count in 64-pin VQFN, and absence of integrated 12-bit ADC (unlike F552x variants).

Technical Context

The MSP430F5513IRGCR implements a 16-bit RISC CPU with constant generators and digitally controlled oscillator (DCO), enabling 25-MHz system clock operation. Its unified clock system includes FLL stabilization, low-frequency VLO and REFO internal sources, 32-kHz XT1 crystal support, and up to 32-MHz XT2 crystal input.

Power management integrates a programmable LDO core regulator, supply voltage supervisor (SVS), brownout reset (BOR), and five low-power modes (LPM0–LPM4.5). Peripherals include three-channel DMA, hardware multiplier (MPY32), four 16-bit timers (TA0/TA1/TA2/TB0), two USCIs (USCI_A0/A1/B0/B1), RTC_A, COMP_B (8-channel), and USB module with eight endpoints.

FAQ

Does the MSP430F5513IRGCR include an integrated 12-bit analog-to-digital converter (ADC)?

No, the MSP430F5513IRGCR does not include the ADC12_A module. Unlike the MSP430F552x series, the F551x family (including MSP430F5513IRGCR) omits the 12-bit ADC. This is confirmed in the device comparison and functional block diagrams - Figure 4-4 explicitly shows no ADC12_A block for MSP430F5513IRGCR. External ADCs or alternative F552x variants must be used if analog digitization is required.

What is the maximum system clock frequency supported by the MSP430F5513IRGCR?

The MSP430F5513IRGCR supports a maximum system clock frequency of 25 MHz. This is achieved using the FLL-controlled DCO or high-frequency crystals up to 32 MHz on XT2. The 25-MHz limit is specified in the "Description" section and validated across all operating conditions in the "Recommended Operating Conditions" table (Section 8.3) of the datasheet.

Which USB speed and protocol classes does the MSP430F5513IRGCR support?

The MSP430F5513IRGCR supports full-speed USB 2.0 (12 Mbps) and implements standard USB device classes including CDC ACM (virtual COM port), HID, and MSC (mass storage) via software stack. Its integrated USB-PHY, USB-PLL, and eight endpoints enable compliant enumeration and data transfer without external transceivers or clock sources.

How many general-purpose I/O pins does the MSP430F5513IRGCR provide in its VQFN-64 package?

The MSP430F5513IRGCR provides 47 general-purpose I/O pins in the RGC (VQFN-64) package. This is explicitly stated in the "Description" section: "The MSP430F5514 and MSP430F5513 microcontrollers [...] have 47 I/O pins." Pin diagrams and signal descriptions in Section 7 confirm allocation across Ports P1–P6, with dedicated USB (DP/DM/PUR), reset, and crystal pins excluded from GPIO count.

What is the lowest power-consumption mode available on the MSP430F5513IRGCR, and what is its typical current draw?

The lowest power-consumption mode is LPM4.5 (shutdown mode), with a typical current draw of 0.18 µA at 3.0 V. In this mode, the supply supervisor remains active, full RAM is retained, and wake-up is possible via RST/NMI or selected I/O interrupts. This value is measured and published in Section 8.5 ("Low-Power Mode Supply Currents") of the official datasheet.
