Product details
Overview
MSP430F5529IPN from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, 128 KB flash, 8 KB + 2 KB RAM, 12-bit ADC (200 ksps, 16 channels), four 16-bit timers, two USCI modules, and RTC-designed for battery-powered sensor systems and USB-connected data loggers.
For engineers reviewing the MSP430F5529IPN datasheet, MSP430F5529IPN pinout, MSP430F5529IPN application, or MSP430F5529IPN equivalent, key selection criteria include USB PHY integration, LPM3 standby current (1.9 µA at 3.0 V), 80-pin LQFP package compatibility, and full peripheral set including ADC12_A and hardware multiplier.
Technical Context
The MSP430F5529IPN implements a 16-bit RISC CPUXV2 core with constant generators and unified clock system featuring FLL stabilization, dual crystal support (XT1 up to 32 kHz, XT2 up to 32 MHz), and low-power oscillators (VLO, REFO). Its power management includes an integrated LDO with programmable core voltage and supply supervision with brownout detection.
Peripherals are tightly coupled to the DMA controller (3-channel) and interrupt architecture, enabling autonomous operation in low-power modes. The USB subsystem integrates PHY, PLL, 3.3-V/1.8-V power system, and eight endpoints-supporting full-speed (12 Mbps) device-mode operation without external components.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5527IPN | Same 80-pin LQFP package, identical USB/ADC/timer peripherals, but 96 KB flash and 6 KB + 2 KB RAM. | Suitable where firmware size exceeds 128 KB or RAM buffer requirements are lower. | Select when firmware footprint is <96 KB and cost sensitivity favors smaller memory configuration. |
| MSP430F5528IRGC | 64-pin VQFN (9 mm × 9 mm), 128 KB flash, 8 KB + 2 KB RAM, but only 47 GPIO and 12-channel ADC. | Better suited for space-constrained designs with fewer analog inputs and no LCD/complex I/O needs. | Choose for compact layouts requiring USB and moderate analog I/O-accepts trade-off of reduced pin count and ADC channel count. |
Compared with MSP430F5527IPN, the MSP430F5529IPN offers larger flash for complex USB stacks or OTA-ready firmware; versus MSP430F5528IRGC, it delivers 16 additional GPIO and 4 extra ADC channels at the cost of larger footprint-critical for sensor-rich, expandable designs.

FAQ
What USB speed and device classes does the MSP430F5529IPN support?
The MSP430F5529IPN supports full-speed USB 2.0 (12 Mbps) in device mode only. It implements the USB specification at the PHY and link layer, enabling standard device classes including CDC ACM (virtual COM port), HID, MSC (mass storage), and custom vendor-defined classes via its eight configurable endpoints. The MSP430F5529IPN does not support USB host mode or high-speed operation.
Does the MSP430F5529IPN require external components for USB functionality?
No, the MSP430F5529IPN integrates a full USB 2.0 PHY, USB-PLL, and dual-voltage power system (3.3 V and 1.8 V), eliminating the need for external transceivers, termination resistors, or voltage regulators. Only the DP/DM lines and optional PUR pin control are required; the MSP430F5529IPN handles all physical-layer signaling internally.
What is the maximum sampling rate and resolution of the integrated ADC on the MSP430F5529IPN?
The MSP430F5529IPN features a 12-bit successive-approximation ADC (ADC12_A) with a maximum conversion rate of 200 ksps. It supports autoscan across 16 input channels (14 external, 2 internal), internal reference voltage (1.5 V or 2.5 V), sample-and-hold, and configurable conversion timing-all without CPU intervention using DMA triggers.
How many low-power modes does the MSP430F5529IPN support, and what is the lowest active current?
The MSP430F5529IPN supports six low-power modes (LPM0–LPM4.5). Active mode (AM) current is 290 µA/MHz at 8 MHz and 3.0 V during flash execution. The lowest operational mode is LPM4.5 (shutdown), drawing just 0.18 µA at 3.0 V with full RAM retention and fast wakeup-ideal for energy-harvesting or maintenance-free deployments.
Is the MSP430F5529IPN pin-compatible with other devices in the MSP430F55xx family?
Yes, the MSP430F5529IPN in the 80-pin LQFP (PN) package shares identical pinout with MSP430F5527IPN, MSP430F5525IPN, and MSP430F5521IPN. This allows direct substitution within the same footprint for memory- or feature-downgraded variants, provided firmware accommodates differences in flash/RAM size and peripheral enablement.
