MSP430F5529 16-bit Ultra-Low-Power MCU

Specifications

Product Overview

The Texas Instruments MSP430F5529 is a 16-bit ultra-low-power MCU built around the MSP430F55xx 16-bit RISC architecture. It supports an operating supply voltage range of 1.8 V to 3.6 V and a system clock up to 25 MHz. For the MSP430F5529IPN ordering option, the package is LQFP (80), 12 mm × 12 mm, supporting board-level assembly where an 80-pin package is appropriate. The device integrates a full-speed USB 2.0 interface with an integrated PHY, providing 8 input and 8 output endpoints for peripheral connectivity. Its power management system features multiple low-power modes including LPM3 standby with full RAM retention, consuming only 1.9 µA typical at 2.2 V, and LPM4.5 shutdown mode at 0.18 µA typical. Clock generation is handled by a unified clock system offering low-power VLO, trimmed REFO, 32-kHz watch crystal (XT1), and high-frequency crystal up to 32 MHz (XT2). On-chip peripherals include a 12-bit ADC with 12 channels, three 16-bit Timer_A modules, one 16-bit Timer_B module, two universal serial communication interfaces supporting UART, SPI, and I2C, a real-time clock with alarm capabilities, 3-channel DMA, a comparator, and a 32-bit hardware multiplier. These specifications make the MSP430F5529 suitable for embedded designs that require a balance of processing capability, USB connectivity, analog measurement, and low standby power consumption.

Procurement Notes

When requesting a quote for MSP430F5529, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.

If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.

For MCU, processor and logic IC sourcing, package, operating voltage, temperature grade, speed or frequency grade, firmware or mask version, lifecycle status and programming requirements should be checked before approval.
