Product details
Overview
MSP430F5505IRGZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with integrated USB 2.0 PHY, 16 KB flash, 4 KB + 2 KB RAM, 10-bit ADC (6 external + 2 internal channels), single USCI (UART/IrDA/SPI/I²C), four 16-bit timers, RTC, hardware multiplier, and DMA - designed for battery-powered sensor nodes and USB-connected data loggers.
For engineers reviewing the MSP430F5505IRGZR datasheet, MSP430F5505IRGZR pinout, MSP430F5505IRGZR application, or MSP430F5505IRGZR equivalent, key selection criteria include USB PHY integration, 31 I/O count in 48-pin VQFN, LPM4.5 shutdown current (0.18 µA), 16 KB flash size, and single-USCI peripheral configuration versus higher-family variants.
Technical Context
The MSP430F5505IRGZR implements a unified clock system with FLL stabilization, dual crystal support (XT1 for 32-kHz RTC, XT2 up to 32 MHz), and low-power internal sources (VLO, REFO). Its power management includes an integrated LDO with programmable core voltage and supply supervision with brownout detection.
It executes code from flash at up to 25 MHz with 195 µA/MHz active-mode current (3 V, 8 MHz), supports fast wake-up (<5 µs) from LPM3 standby, and uses port mapping on P4 to configure USCI functions - limiting simultaneous signal availability per package constraints.
