Product Overview
The MSP430F5528 is a Texas Instruments ultra-low-power mixed-signal MCU built around the MSP430F55xx 16-bit RISC architecture. It operates from a 1.8 V to 3.6 V supply and supports a system clock up to 25 MHz, with an integrated LDO for programmable regulated core supply voltage. Low-power operation includes LPM3, LPM4, and LPM4.5 modes, with typical shutdown current of 0.18 uA at 3.0 V in LPM4.5 and a typical 3.5 us wakeup from standby to active mode.
The device integrates a unified clock system with FLL control loop, VLO, REFO, XT1 32-kHz watch-crystal support, and XT2 high-frequency crystal support up to 32 MHz. Peripheral resources include Timer_A and Timer_B blocks, 2 USCIs supporting UART, IrDA, SPI, and I2C modes, a full-speed USB interface, 12-bit ADC, COMP_B comparator channels, MPY32 hardware multiplier, 3-channel DMA, RTC features, and 47 I/O pins.
Package options cover VQFN (64) 9 mm x 9 mm, DSBGA (64), nFBGA (80) 5 mm x 5 mm, and MicroStar Junior BGA (80) 5 mm x 5 mm. These electrical and package characteristics support compact embedded control, USB interface, sensing, timing, and low-power data-acquisition designs.
