Product details
Overview
MSP430F5509IRGCR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with integrated full-speed USB 2.0 PHY, 24 KB flash, 4 KB + 2 KB RAM, 10-bit ADC (6 external + 2 internal channels), two USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers, RTC, hardware multiplier, and DMA - designed for battery-powered sensor systems and USB-connected data loggers.
For engineers reviewing the MSP430F5509IRGCR datasheet, MSP430F5509IRGCR pinout, MSP430F5509IRGCR application, or MSP430F5509IRGCR equivalent, key selection criteria include USB PHY integration, 48-pin VQFN (7 mm × 7 mm) package compatibility, LPM4.5 shutdown current (0.18 µA), dual USCI support, and 24 KB flash capacity for firmware-rich embedded USB peripherals.
Technical Context
The MSP430F5509IRGCR implements a 16-bit RISC CPU with constant generators and extended memory addressing, paired with a unified clock system featuring FLL stabilization, VLO/REFO internal sources, and support for 32-kHz XT1 and up to 32-MHz XT2 crystals. Its power management includes an integrated LDO with programmable core voltage and supply supervision.
USB functionality is fully integrated: dedicated USB-PHY, USB-PLL, dual 3.3-V/1.8-V USB power rails, eight endpoints (4 IN + 4 OUT), and automatic suspend/resume handling. The device supports port-mapped USCI functions on P4, enabling flexible UART/I²C/SPI routing under software control.
