Texas Instruments MSP430F5525IPN

Overview

MSP430F5525IPN 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 USCIs, RTC, and 63 GPIO pins in an 80-pin LQFP package. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems requiring USB connectivity and precise analog acquisition.

For engineers reviewing the MSP430F5525IPN datasheet, MSP430F5525IPN pinout, MSP430F5525IPN application, or MSP430F5525IPN equivalent, key selection criteria include USB 2.0 PHY integration, 12-bit ADC channel count and sampling rate, LPM3/LPM4 current consumption at 3.0 V, wake-up time from standby, and 80-pin LQFP package compatibility with existing MSP430F552x design layouts.

Technical Context

The MSP430F5525IPN implements a 16-bit RISC CPU with extended memory addressing, digitally controlled oscillator (DCO) stabilized by FLL, and unified clock system supporting XT1 (32-kHz crystal), XT2 (up to 32 MHz), REFO, and VLO sources. Its power architecture includes an integrated LDO with programmable core voltage, supply supervision, and brownout detection.

Peripherals are tightly coupled to the 3-channel DMA controller and port mapping logic, enabling low-CPU-overhead data movement for USB transfers, ADC conversions, and timer-triggered I/O operations. The device supports full-speed USB 2.0 via integrated PHY, USB-PLL, and dual 3.3-V/1.8-V USB power system - all without external components.

FAQ

What USB speed and device classes does the MSP430F5525IPN support?

The MSP430F5525IPN supports full-speed USB 2.0 (12 Mbps) with integrated PHY, USB-PLL, and dual-voltage power system. It natively implements USB device functionality including CDC, HID, and MSC classes via firmware - no external transceiver required. The MSP430F5525IPN USB module includes eight endpoints (four IN, four OUT) and supports descriptor-based enumeration compliant with USB 2.0 specification.

Does the MSP430F5525IPN include a hardware ADC and what are its key analog specifications?

Yes, the MSP430F5525IPN integrates a 12-bit ADC (ADC12_A) with 200 ksps maximum sample rate, 16 input channels (14 external, 2 internal), autoscan mode, and selectable internal reference (1.5 V or 2.5 V). It supports sample-and-hold, burst conversion, and hardware-triggered sequences - all confirmed in the SLAS590P datasheet Section 8.35–8.39 for the MSP430F5525IPN variant.

What is the standby current consumption of the MSP430F5525IPN and under what conditions is it measured?

The MSP430F5525IPN draws 1.9 µA in Standby mode (LPM3) at 3.0 V with RTC, watchdog, and supply supervisor active and full RAM retention - per SLAS590P datasheet Section 8.5. This value is measured with VLO disabled, REFO enabled, and crystal oscillator (XT1) running at 32.768 kHz. Fast wakeup occurs in 3.5 µs, enabling responsive sensor event handling.

Which package and pin count does the MSP430F5525IPN use, and is it pin-compatible with other MSP430F552x devices?

The MSP430F5525IPN uses an 80-pin LQFP (PN) package, 12 mm × 12 mm body size. It shares identical pinout, package dimensions, and signal assignments with MSP430F5529IPN and MSP430F5527IPN - confirmed in Figure 4-1 and Device Information table of SLAS590P. This enables direct PCB footprint reuse across the 80-pin MSP430F552x family.

What low-power modes and wake-up sources are available on the MSP430F5525IPN?

The MSP430F5525IPN supports five low-power modes: AM (active), LPM0–LPM3 (with varying clocks disabled), LPM4 (full RAM retention, supply supervisor only), and LPM4.5 (shutdown). Wake-up sources include RTC alarm, GPIO interrupts, comparator output, timer expiration, USCI receive events, and USB resume - all documented in Section 9.2 of SLAS590P for the MSP430F5525IPN.
