Texas Instruments MSP430F5529IPNR

Overview

MSP430F5529IPNR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with integrated USB 2.0 PHY, 128 KB flash, 8 KB + 2 KB RAM, 63 GPIO, and a 12-bit 200 ksps ADC. It operates from 1.8 V to 3.6 V and achieves 290 µA/MHz active current at 8 MHz (flash execution) and 1.9 µA standby (LPM3 with RTC). It targets battery-powered sensor nodes requiring USB connectivity and precise analog acquisition.

For engineers reviewing the MSP430F5529IPNR datasheet, MSP430F5529IPNR pinout, MSP430F5529IPNR application, or MSP430F5529IPNR equivalent, key selection criteria include USB PHY integration, 63-pin LQFP package compatibility, 12-bit ADC channel count (16 total, 14 external), wake-up time from LPM3 (3.5 µs), and support for full-speed USB host enumeration without external transceivers.

Technical Context

The MSP430F5529IPNR implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling 3.5 µs wake-up from LPM3. Its unified clock system integrates FLL stabilization, dual crystal oscillators (XT1 up to 32 kHz, XT2 up to 32 MHz), REFO, and VLO - all programmable via software-controlled registers.

Peripherals include four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules supporting UART/IrDA/SPI/I²C, hardware multiplier (MPY32), 3-channel DMA, RTC_A with alarm, and COMP_B. The integrated USB subsystem provides eight endpoints, USB-PLL, dual LDOs (3.3 V and 1.8 V), and full PHY compliance per USB 2.0 specification.

FAQ

What USB speed and device classes does the MSP430F5529IPNR support?

The MSP430F5529IPNR supports full-speed USB 2.0 (12 Mbps) with integrated PHY, USB-PLL, and dual LDOs. It natively implements CDC, HID, and MSC device classes via firmware - no external transceiver required. The USB module includes eight endpoints, configurable buffers, and automatic suspend/resume handling, enabling robust host enumeration and data transfer in MSP430F5529IPNR-based designs.

Does the MSP430F5529IPNR include a hardware ADC and what are its key analog specs?

Yes, the MSP430F5529IPNR integrates a 12-bit SAR ADC (ADC12_A) with 200 ksps maximum sampling rate, 16 input channels (14 external, 2 internal), sample-and-hold, autoscan mode, and selectable internal reference (1.5 V or 2.5 V). It supports single-ended and differential inputs, programmable conversion timing, and DMA-triggered transfers - all confirmed in the MSP430F5529IPNR datasheet Section 8.35–8.39.

What is the lowest power consumption mode available on the MSP430F5529IPNR and how is it configured?

The MSP430F5529IPNR achieves 0.18 µA in LPM4.5 (shutdown mode) with full RAM retention and supply supervisor active. This mode disables all clocks and core logic while preserving register state. Entry requires writing specific bits to the SCG0, SCG1, OSCOFF, and CPUOFF registers, then executing LPM4.5 instruction - verified in Section 9.2 of the MSP430F5529IPNR datasheet.

How many GPIO pins does the MSP430F5529IPNR provide and what I/O features are supported?

The MSP430F5529IPNR provides 63 GPIO pins in its LQFP-80 package. Each pin supports programmable pullup/pulldown resistors, Schmitt-trigger inputs, full/reduced drive strength, and peripheral function multiplexing via port-select registers. All GPIO retain state in LPM3/LPM4, and 20 pins support capacitive touch I/O - details confirmed in Section 7.2 and Table 7-1 of the MSP430F5529IPNR datasheet.

Is the MSP430F5529IPNR pin-compatible with other members of the MSP430F55xx family?

Yes, the MSP430F5529IPNR shares identical pinout and package (LQFP-80) with MSP430F5527IPN, MSP430F5525IPN, and MSP430F5521IPN. These variants differ only in flash/RAM size and peripheral enablement - e.g., MSP430F5527IPN has 96 KB flash and same ADC - making them drop-in replacements where memory requirements align, as documented in TI's Device Comparison table (Section 6).
