Product details
Overview
MSP430F5526IYFFT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, 64 KB flash, 8 KB + 2 KB RAM, 47 GPIO pins, and a 12-bit ADC with 12 input channels (10 external, 2 internal). It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and USB-connected data loggers requiring sub-2 µA standby current and 3.5 µs wake-up.
For engineers reviewing the MSP430F5526IYFFT datasheet, MSP430F5526IYFFT pinout, MSP430F5526IYFFT application, or MSP430F5526IYFFT equivalent, key selection criteria include verified USB 2.0 PHY integration, LPM3 current of 1.9 µA at 3.0 V, 12-bit ADC autoscan capability, DSBGA-64 package footprint, and compatibility with MSP430Ware™ development tools.
Technical Context
The MSP430F5526IYFFT 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, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz) sources.
It features four 16-bit timers (TA0/TA1/TA2/TB0), two USCIs supporting UART/IrDA/SPI/I²C, full-speed USB 2.0 with integrated PHY/LDO/PLL, hardware multiplier, 3-channel DMA, RTC_A module, and COMP_B with 8 channels - all optimized for deterministic real-time control in energy-constrained systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power USB MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5528IRGC | VQFN-64 package (9 mm × 9 mm); identical peripheral set and memory (64 KB flash, 8 KB + 2 KB RAM) | Requires larger PCB footprint and different thermal management; compatible with standard QFN reflow profiles | Select when board space allows larger package and thermal pad soldering is preferred over DSBGA assembly. |
| MSP430F5524IRGC | VQFN-64; reduced flash (32 KB) and RAM (4 KB + 2 KB); same 47 GPIO and USB/ADC/timer peripherals | Suitable for cost-sensitive designs with smaller firmware footprints and lower buffer requirements | Choose when application code fits in 32 KB flash and 4 KB RAM suffices for USB endpoint buffers and sensor data queues. |
Compared with MSP430F5526IYFFT, the MSP430F5528IRGC offers identical functionality in a more manufacturable VQFN package but increases board area by 10×; the MSP430F5524IRGC reduces memory to cut cost while retaining USB and ADC capabilities for simpler firmware deployments.

FAQ
What is the maximum operating frequency of the MSP430F5526IYFFT?
The MSP430F5526IYFFT supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This frequency is validated across the full operating voltage range (1.8 V to 3.6 V) and temperature range (–40°C to 85°C), enabling deterministic real-time execution for time-critical sensor fusion and USB transaction handling in the MSP430F5526IYFFT.
Does the MSP430F5526IYFFT include an integrated USB transceiver?
Yes, the MSP430F5526IYFFT integrates a full-speed USB 2.0 physical layer (PHY), USB power system (3.3-V and 1.8-V LDOs), and USB-PLL - eliminating the need for external transceivers or voltage regulators. This integration is confirmed in the functional block diagram (Figure 4-2) and electrical specifications (Sections 8.44–8.47) of the MSP430F5526IYFFT datasheet.
How many analog input channels does the ADC support on the MSP430F5526IYFFT?
The MSP430F5526IYFFT features the ADC12_A module with 12 total input channels: 10 external analog inputs (A0–A9) and 2 internal sources (temperature sensor and VREF/2). This configuration is explicitly stated in the "Description" section and functional block diagram (Figure 4-2) for the MSP430F5526IYFFT, distinguishing it from higher-pin-count variants with 16 channels.
What is the standby current consumption of the MSP430F5526IYFFT in LPM3 mode?
In LPM3 mode with RTC, watchdog, and supply supervisor active and full RAM retention, the MSP430F5526IYFFT consumes 1.9 µA at 3.0 V (typical), as specified in Section 1 "Features" and Table 8.5 of the datasheet. This value is measured with a 32.768 kHz crystal connected to XT1 and reflects the lowest power state enabling timekeeping and fast wakeup.
Which development tools are officially supported for the MSP430F5526IYFFT?
Texas Instruments officially supports the MSP430F5526IYFFT with the MSP-EXP430F5529LP LaunchPad™ (via software compatibility), MSP-TS430RGC64USB target board (with adapter), and MSP430Ware™ software suite. Code Composer Studio™ IDE provides full debugging, and TI Resource Explorer delivers validated code examples - all documented in Section 3 and "Tools and Software" (Section 10.3) for the MSP430F5526IYFFT.
