Product Overview
The MSP430F5527 is a Texas Instruments ultra-low-power mixed-signal MCU built around the 16-bit RISC MSP430F552x architecture. It operates from 1.8 V to 3.6 V with a system clock frequency up to 25 MHz. Active-mode current is 290 uA/MHz typical (flash, 8 MHz, 3.0 V) or 150 uA/MHz typical (RAM, same conditions).
For low-power operation, the device supports LPM3 standby with full RAM retention at 1.9 uA typical (RTC crystal, 2.2 V) or 2.1 uA typical (3.0 V, same mode). LPM4 consumes 1.1 uA typical and LPM4.5 shutdown draws 0.18 uA typical. Wakeup from standby to active takes 3.5 us typical.
The PN package is an 80-pin LQFP measuring approximately 12 mm x 12 mm. Integrated peripherals include full-speed USB 2.0 with PHY, USB power system and PLL, a 12-bit ADC (12 channels), 63 I/O pins, Timer_A and Timer_B resources, two USCI modules (UART, IrDA, SPI, I2C), 3-channel DMA, MPY32 hardware multiplier, JTAG, and Spy-Bi-Wire debug.
