MSP430F5528 16-bit Mixed-Signal Microcontroller

Specifications

Product Overview

The MSP430F5528 is a 16-bit mixed-signal microcontroller from Texas Instruments based on the MSP430 CPU architecture. It integrates a 16-bit RISC CPU running at up to 25 MHz with a rich set of peripherals for low-power embedded control applications. The device operates from a 1.8 V to 3.6 V supply range and includes an integrated LDO with programmable regulated core supply voltage for flexible power management. For peripheral integration, the MSP430F5528 includes 47 I/O pins, USB 2.0 full-speed operation with integrated USB PHY, 8 input endpoints, 8 output endpoints, an integrated 3.3 V and 1.8 V USB power system, and an integrated USB-PLL. Analog and timing resources include a 12-bit ADC with 12 channels (10 external and 2 internal), Timer_A0 with 5 capture/compare registers, Timer_A1 and Timer_A2 with 3 capture/compare registers each, and Timer_B0 with 7 capture/compare shadow registers. The device also supports serial communication via two USCIs providing UART, IrDA, SPI, and I2C interfaces, three DMA channels, and a hardware multiplier for 32-bit operations. Clock system includes VLO, REFO, XT1, and XT2 sources, with support for 32-kHz watch crystals and high-frequency crystals up to 32 MHz.

Procurement Notes

When requesting a quote for MSP430F5528, 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.
