Product details
Overview
MSP430F5527IPN from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, 12-bit ADC (200 ksps, 16-channel autoscan), four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), and RTC. It operates from 1.8 V to 3.6 V and delivers 290 µA/MHz active current at 8 MHz (flash execution) and 1.9 µA standby (LPM3 with RTC). It targets USB-connected sensor nodes and portable data loggers requiring long battery life and on-chip signal acquisition.
For engineers reviewing the MSP430F5527IPN datasheet, MSP430F5527IPN pinout, MSP430F5527IPN application, or MSP430F5527IPN equivalent, key selection criteria include USB PHY integration, 63 GPIO count in LQFP-80, 12-bit ADC channel count and sample rate, low-power mode wake-up time (3.5 µs), and core voltage regulation via integrated LDO - all confirmed for the exact MSP430F5527IPN variant.
Technical Context
The MSP430F5527IPN 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), VLO, and REFO. Its power architecture includes programmable LDO core regulation, supply voltage supervisor (SVS), brownout reset (BOR), and five low-power modes (LPM0–LPM4.5).
Peripherals are tightly coupled to DMA (3 channels) and interrupt vectors: ADC12_A supports 16 external + 2 internal inputs with autoscan; USB module provides full-speed operation with integrated 3.3-V/1.8-V power system and USB-PLL; Timer_B0 offers 7 capture/compare shadow registers for precise PWM and event timing.

FAQ
What USB speed and device classes does the MSP430F5527IPN support?
The MSP430F5527IPN supports full-speed USB 2.0 (12 Mbps) with integrated PHY and power system. It natively implements USB device classes including CDC (virtual COM port), HID (human interface device), and MSC (mass storage) via TI-provided USB stack libraries. The MSP430F5527IPN does not support high-speed USB or USB host functionality - it operates exclusively as a USB peripheral device.
Does the MSP430F5527IPN include a hardware real-time clock (RTC)?
Yes, the MSP430F5527IPN integrates RTC_A - a calendar-mode real-time clock with alarm, calibration, and battery-backup capability. It operates in LPM3 with 32.768-kHz crystal (XT1) and maintains full RAM retention. The MSP430F5527IPN RTC supports time-of-day stamping, periodic interrupts, and wake-up events - essential for time-stamped data logging without external RTC ICs.
What is the maximum ADC sampling rate and channel count for the MSP430F5527IPN?
The MSP430F5527IPN features ADC12_A with a maximum sampling rate of 200 ksps and supports up to 16 external analog inputs plus 2 internal sources (temperature sensor and VREF). Channel autoscan enables sequential conversion without CPU overhead. This specification is confirmed for the MSP430F5527IPN and matches the MSP430F5529IPN and MSP430F5525IPN variants in the same PN-package group.
How many GPIO pins are available on the MSP430F5527IPN, and what packaging does it use?
The MSP430F5527IPN provides 63 GPIO pins in an LQFP-80 (12 mm × 12 mm) package with exposed thermal pad. All I/Os support multiple functions including analog input, timer capture/compare, USCI signals, and USB DP/DM. Pin mapping is identical across MSP430F5529IPN, MSP430F5527IPN, and MSP430F5525IPN - enabling drop-in replacement within the same memory tier.
What low-power modes and wake-up times are specified for the MSP430F5527IPN?
The MSP430F5527IPN supports five low-power modes: LPM0–LPM4.5. Wake-up from LPM3 (RTC active) takes 3.5 µs (typical) to active mode. LPM4.5 achieves 0.18 µA shutdown current at 3.0 V. These values are measured and specified for the MSP430F5527IPN in its LQFP-80 package under standard conditions - matching the performance of MSP430F5529IPN and MSP430F5525IPN in the same functional block diagram group.
