Texas Instruments MSP430F5517IPN

Overview

MSP430F5517IPN from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated full-speed 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 features 96 KB Flash, 6 KB + 2 KB SRAM, 63 I/O pins, and operates from 1.8 V to 3.6 V - designed for battery-powered sensor systems and USB-connected data loggers.

For engineers reviewing the MSP430F5517IPN datasheet, MSP430F5517IPN pinout, MSP430F5517IPN application, or MSP430F5517IPN equivalent, key selection criteria include USB PHY integration, LPM3 current (1.9 µA), wake-up time (3.5 µs), 63-pin LQFP package, and absence of integrated ADC - distinguishing it from F552x variants.

Technical Context

The MSP430F5517IPN implements a unified clock system with FLL stabilization, dual crystal support (XT1 for 32-kHz RTC, XT2 up to 32 MHz), and internal sources (VLO, REFO). Its power management includes an integrated LDO with programmable core voltage and supply supervision (SVS/SVM/BOR).

It executes code from Flash or RAM with CPUXV2 core, constant generators, and EEM (Enhanced Emulation Module). The device supports JTAG and Spy-Bi-Wire debugging, and its 63 GPIOs are mapped across Ports P1–P8 and PJ with configurable drive strength and Schmitt-trigger inputs.

Key Specifications

Pinout & Package

The MSP430F5517IPN is housed in an 80-pin LQFP (PN) package measuring 12 mm × 12 mm with exposed thermal pad (not electrically connected). Pin functions are defined per TI SLAS590N Rev. September 2018, Figure 4-1 and Section 4.2.

FAQ

Does the MSP430F5517IPN include an integrated analog-to-digital converter (ADC)?

No, the MSP430F5517IPN does not integrate an ADC. Per TI SLAS590N Section 3.1 Device Comparison, ADC12_A is explicitly omitted from all MSP430F551x devices (including MSP430F5517IPN), unlike the F552x series. Designers must use external ADCs or select F552x variants if on-chip 12-bit conversion is required.

What is the maximum system clock frequency supported by the MSP430F5517IPN?

The MSP430F5517IPN supports a maximum system clock (MCLK) frequency of 25 MHz, as specified in the "16-Bit RISC Architecture, Extended Memory, up to 25-MHz System Clock" feature list (SLAS590N Section 1.1). This is achieved using the FLL with XT2 (up to 32 MHz) or DCO calibration.

Is the MSP430F5517IPN pin-compatible with other devices in the MSP430F55xx family?

Yes - the MSP430F5517IPN shares the same 80-pin LQFP (PN) package and pinout with MSP430F5519IPN and MSP430F5515IPN (per Figure 1-3 and Table 3-1). All three support identical I/O mapping, USB, timer, and USCI signal locations, enabling hardware reuse across memory variants.

What USB speed and protocol layers does the MSP430F5517IPN support?

The MSP430F5517IPN supports full-speed USB 2.0 (12 Mbps) with integrated PHY, USB-PLL, and endpoint controller. It implements USB device-side functionality only (no host mode) and requires external software stack (e.g., TI USB stack) for class-specific protocols like CDC, HID, or MSC - the hardware provides physical layer and endpoint management.

How does the power management of the MSP430F5517IPN differ from earlier MSP430 generations?

The MSP430F5517IPN integrates a programmable LDO for core voltage regulation (1.3–1.45 V), supply voltage supervision (SVS/SVM), and brownout reset (BOR) - unlike older generations requiring external regulators. Its LPM3 current (1.9 µA) and 3.5-µs wake-up are optimized for USB-aware low-power operation, with dedicated USB power domains (VUSB/VSSU) and automatic PUR control.
