Product details
Overview
MSP430F5509IZXH 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 nodes and USB-connected data loggers.
For engineers reviewing the MSP430F5509IZXH datasheet, MSP430F5509IZXH pinout, MSP430F5509IZXH application, or MSP430F5509IZXH equivalent, key selection criteria include USB PHY integration, 80-pin nFBGA package (5 mm × 5 mm), LPM4.5 shutdown current (0.18 µA), RTC alarm capability, and dual USCI support with port-mapped flexibility on P4.
Technical Context
The MSP430F5509IZXH implements a unified clock system with FLL stabilization, VLO/REFO/XT1/XT2 sources, and programmable LDO core regulation. Its CPUXV2 core executes instructions at up to 25 MHz with <5 µs wakeup from LPM3 standby mode.
Peripherals are organized around three-channel DMA, dual USCI modules (USCI_A0/A1 supporting UART/IrDA/SPI; USCI_B0/B1 supporting I²C/SPI), and Timer_B0 with seven capture/compare shadow registers - enabling precise PWM generation and input capture in USB-synchronized timing applications.

FAQ
What is the maximum operating frequency of the MSP430F5509IZXH?
The MSP430F5509IZXH supports a maximum system clock frequency of 25 MHz, enabled by its digitally controlled oscillator (DCO) and FLL-based clock stabilization. This allows high-throughput execution of USB packet handling, ADC conversions, and real-time signal processing while maintaining ultra-low active-mode current (195 µA/MHz at 8 MHz, 3 V). The MSP430F5509IZXH achieves this performance within its 1.8–3.6 V supply range.
Does the MSP430F5509IZXH require an external USB transceiver?
No, the MSP430F5509IZXH integrates a full-speed USB 2.0 PHY, eliminating the need for an external transceiver. It provides dedicated DP and DM pins, internal 1.5-kΩ pull-up (controlled via PUR pin), and dual USB power rails (3.3 V and 1.8 V). This integration reduces bill-of-materials cost, PCB area, and design complexity - a key differentiator of the MSP430F5509IZXH versus non-USB MCUs.
How many analog input channels does the ADC in the MSP430F5509IZXH support?
The MSP430F5509IZXH features the ADC10_A module with six external analog input channels (A0–A5 on P6.x) and two internal channels (VeREF+ and VeREF− on P5.0/P5.1), totaling eight selectable inputs. It delivers 10-bit resolution at up to 200 ksps with built-in window comparator functionality - enabling threshold-triggered interrupts without CPU intervention. This configuration is confirmed for the MSP430F5509IZXH in the device comparison table and functional block diagrams.
What low-power modes are available on the MSP430F5509IZXH, and what is the lowest current draw?
The MSP430F5509IZXH offers six low-power modes (LPM0–LPM4.5). The deepest state is LPM4.5 (shutdown mode), drawing just 0.18 µA at 3 V with full RAM retention and fast wakeup. LPM3 (RTC mode) draws 1.9 µA at 2.2 V, keeping the real-time clock, watchdog, and supply supervisor active. These values are measured and specified in the datasheet's Section 5.5 and reflect actual silicon behavior - critical for battery-life estimation in the MSP430F5509IZXH.
Is the MSP430F5509IZXH pin-compatible with other devices in the F55xx family?
Yes, the MSP430F5509IZXH shares identical pinout and package (80-pin nFBGA, ZXH) with MSP430F5510IZXH and MSP430F5508IZXH. All three support the same peripheral mappings, voltage domains, and USB interface signaling on the ZXH footprint. This allows direct substitution in existing layouts when flash requirements change - for example, upgrading to MSP430F5510IZXH for larger firmware or downgrading to MSP430F5508IZXH for cost optimization - without PCB revision.
