Product details
Overview
MSP430F5509IRGCT 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 MSP430F5509IRGCT datasheet, MSP430F5509IRGCT pinout, MSP430F5509IRGCT application, or MSP430F5509IRGCT equivalent, key selection criteria include USB PHY integration, 48-pin VQFN (7 mm × 7 mm) package compatibility, LPM4.5 shutdown current (0.18 µA), 1.8–3.6 V supply range, and dual-USCI peripheral flexibility for simultaneous UART + I²C or SPI + IrDA interfaces.
Technical Context
The MSP430F5509IRGCT implements a unified clock system with FLL stabilization, programmable LDO core regulation, and flexible port mapping via P4 controller - enabling dynamic reassignment of USCI_A1/USCI_B1 signals to shared pins. Its USB subsystem integrates dedicated 3.3-V and 1.8-V power rails, USB-PLL, and eight bidirectional endpoints without external transceivers.
It supports three low-power modes with sub-5 µs wake-up: LPM3 (1.9 µA @ 2.2 V with RTC active), LPM4 (1.1 µA @ 3 V), and LPM4.5 (0.18 µA). The 10-bit ADC achieves 200 ksps sampling with window comparator and internal reference (REFO), while Timer_B0 provides seven capture/compare registers for complex PWM generation.

FAQ
What USB speed and device classes does the MSP430F5509IRGCT support?
The MSP430F5509IRGCT supports full-speed USB 2.0 (12 Mbps) with an integrated PHY and complies with USB specification 2.0. It implements standard device classes including CDC ACM (virtual COM port), HID, and MSC through firmware - no external USB controller is required. Its eight bidirectional endpoints and dedicated USB-PLL enable robust enumeration and sustained data throughput in MSP430F5509IRGCT-based designs.
Does the MSP430F5509IRGCT require external components for USB functionality?
No, the MSP430F5509IRGCT integrates a full-speed USB PHY, 3.3-V and 1.8-V USB power regulators, USB-PLL, and internal 1.5-kΩ pull-up resistor (controlled by PUR pin), eliminating all external USB transceivers, level shifters, and discrete regulators. Only standard USB-series 27-Ω resistors and proper PCB layout per USB spec are required - significantly reducing BOM and board area for MSP430F5509IRGCT implementations.
How many ADC channels and what resolution does the MSP430F5509IRGCT provide?
The MSP430F5509IRGCT features a 10-bit successive-approximation ADC (ADC10_A) with 200 ksps maximum sampling rate, six external analog inputs (P6.0–P6.5), and two internal channels (VeREF+ and VeREF−). It includes a programmable window comparator for autonomous threshold detection and supports internal reference (REFO) or external VREF - all confirmed in the SLAS645L datasheet for MSP430F5509IRGCT.
What low-power modes and wake-up times are supported by the MSP430F5509IRGCT?
The MSP430F5509IRGCT supports five low-power modes: LPM0–LPM4 and LPM4.5. Wake-up from LPM3 (RTC active) takes less than 5 µs; LPM4.5 (shutdown) draws only 0.18 µA at 3 V. Real-time clock operation, full RAM retention, and fast wake-up are maintained across LPM3/LPM4 - enabling MSP430F5509IRGCT to achieve multi-year battery life in intermittent-sensing applications.
Is the MSP430F5509IRGCT pin-compatible with other devices in the MSP430F55xx family?
Yes, the MSP430F5509IRGCT in the 48-pin VQFN (RGCT) package shares identical pinout and electrical characteristics with MSP430F5510IRGCT, MSP430F5508IRGCT, MSP430F5507IRGCT, and MSP430F5504IRGCT - all use the same RGZ/PT/RGCT footprint. This allows direct substitution within the same package variant, provided firmware accommodates differences in flash size, ADC channel count, and USCI module count.
