Product details
Overview
MSP430F5526IYFFR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, 64 KB flash, 4 KB + 2 KB RAM, 12-bit ADC (12-channel), four 16-bit timers, two USCI modules (UART/IrDA/SPI/I²C), RTC, and hardware multiplier - deployed in portable sensor nodes and USB-connected data loggers.
For engineers reviewing the MSP430F5526IYFFR datasheet, MSP430F5526IYFFR pinout, MSP430F5526IYFFR application, or MSP430F5526IYFFR equivalent, key selection criteria include USB PHY integration, 47 I/O count, DSBGA-64 package footprint, LPM4.5 shutdown current (0.18 µA), and ADC channel count (12) versus higher-pin-count F5529 variants.
Technical Context
The MSP430F5526IYFFR implements a 16-bit RISC CPU with constant generators and digitally controlled oscillator (DCO), enabling 3.5 µs wake-up from LPM3 standby. Its unified clock system integrates FLL stabilization, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz) sources.
Power management includes a programmable LDO core regulator, supply voltage supervisor (SVS), brownout reset (BOR), and five low-power modes (LPM0–LPM4.5). The integrated USB subsystem features dedicated 3.3-V/1.8-V power rails, USB-PLL, and eight endpoints - all operating without external PHY components.

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 |
|---|---|---|---|
| MSP430F5529IPN | 80-pin LQFP, 63 I/O, 128 KB flash, 16-channel ADC, same USB/RTC/timer peripherals | Higher I/O count and flash support complex HMI or multi-sensor fusion; requires larger PCB area | Select when >47 GPIO or >64 KB code space is needed - not pin-compatible with MSP430F5526IYFFR |
| MSP430F5528IRGC | VQFN-64, identical peripheral set and memory, 47 I/O, but no DSBGA packaging | Suitable for reflow assembly with standard stencil; lacks DSBGA's board-area advantage for wearables | Choose for automated SMT lines preferring QFN over BGA - same functionality, different thermal/mechanical profile |
Compared with MSP430F5529IPN, MSP430F5526IYFFR trades I/O count and flash capacity for minimal footprint; compared with MSP430F5528IRGC, it delivers identical functionality in a smaller DSBGA package at the cost of more demanding assembly requirements.

FAQ
What USB speed and compliance level does the MSP430F5526IYFFR support?
The MSP430F5526IYFFR supports full-speed USB 2.0 (12 Mbps) with integrated PHY, USB-PLL, and endpoint controller. It complies with USB 2.0 specification for device enumeration, control transfers, and bulk/intr endpoints - verified per TI SLAS590P test reports. No external transceiver is required for MSP430F5526IYFFR USB operation.
How many analog input channels does the MSP430F5526IYFFR ADC support?
The MSP430F5526IYFFR integrates a 12-bit ADC (ADC12_A) with 12 total input channels: 10 external analog inputs (e.g., P1.0–P1.7, P2.0–P2.1) and 2 internal sources (temperature sensor and VREF generator). This matches the functional block diagram in Figure 4-2 and electrical specs in Section 8.35–8.39 of the datasheet.
What is the minimum supply voltage for active operation of the MSP430F5526IYFFR?
The MSP430F5526IYFFR operates in active mode down to 1.8 V, as specified in the "Low supply voltage range" feature list and confirmed in Section 8.3 (Recommended Operating Conditions). At 1.8 V, maximum system clock frequency is reduced to 8 MHz, while 25 MHz operation requires ≥2.2 V per the DC characteristics table.
Does the MSP430F5526IYFFR support real-time clock (RTC) functionality with crystal backup?
Yes, the MSP430F5526IYFFR includes RTC_A module with calendar mode, alarm capability, and dedicated XT1 oscillator support for 32.768-kHz crystals. It retains full RAM and RTC state in LPM3 (1.9 µA typical), enabling accurate timekeeping during battery-powered standby - documented in Section 3 and Figure 4-2.
What is the wake-up time from LPM3 standby mode for the MSP430F5526IYFFR?
The MSP430F5526IYFFR wakes from LPM3 to active mode in 3.5 µs (typical), as stated in both the Features section and Section 8.26 (Wake-up Times From Low-Power Modes). This timing applies when exiting via RTC alarm, GPIO interrupt, or watchdog timeout - critical for responsive sensor event handling.
