Product details
Overview
MSP430F5509IZQER from Texas Instruments is an ultra-low-power 16-bit 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 MSP430F5509IZQER datasheet, MSP430F5509IZQER pinout, MSP430F5509IZQER application, or MSP430F5509IZQER equivalent, key selection criteria include USB 2.0 endpoint count (8 IN/8 OUT), LPM4.5 shutdown current (0.18 µA), 32-kHz crystal RTC support, and MicroStar Junior™ BGA-80 package compatibility with space-constrained embedded designs.
Technical Context
The MSP430F5509IZQER implements a unified clock system with FLL-based frequency stabilization, dual crystal oscillators (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.
USB functionality is fully integrated: dedicated USB-PHY, on-chip 3.3-V/1.8-V power system, USB-PLL, and endpoint FIFOs - enabling self-contained USB device operation without external transceivers. The port mapping controller on P4 enables flexible USCI signal routing, though simultaneous use of all USCI functions is constrained by pin multiplexing.

FAQ
What is the maximum system clock frequency supported by the MSP430F5509IZQER?
The MSP430F5509IZQER supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization using either internal reference (REFO) or external crystals (XT2 up to 32 MHz). This frequency enables real-time processing of USB transactions and high-speed ADC sampling at 200 ksps without compromising ultra-low-power operation in active mode.
Does the MSP430F5509IZQER require an external USB transceiver?
No, the MSP430F5509IZQER integrates a full-speed USB 2.0 PHY, USB-PLL, and dedicated 3.3-V/1.8-V USB power system - eliminating the need for any external USB transceiver, level shifters, or clock generation components. The DP/DM pins connect directly to the USB connector, and the internal PUR pin controls the 1.5-kΩ pull-up resistor for USB enumeration.
How many analog input channels does the ADC10_A module support on the MSP430F5509IZQER?
The ADC10_A module on the MSP430F5509IZQER supports 8 total input channels: 6 external analog inputs (A0–A5 on P6.x) and 2 internal sources (VeREF+ and VeREF− on P5.0/P5.1). This configuration enables simultaneous monitoring of multiple sensors while retaining internal reference monitoring for supply integrity checks.
What low-power modes are available on the MSP430F5509IZQER, and what is the lowest current draw?
The MSP430F5509IZQER offers six low-power modes (LPM0–LPM4.5). The lowest power state is LPM4.5 (shutdown mode), drawing just 0.18 µA at 3 V with full RAM retention and fast wakeup. LPM3 (standby with RTC) consumes 1.9 µA at 2.2 V, supporting time-stamped wake-up events without external real-time clock circuitry.
Is the MSP430F5509IZQER pin-compatible with other devices in the MSP430F55xx family in the ZQE package?
Yes, the MSP430F5509IZQER is pin-compatible with MSP430F5510IZQER and MSP430F5508IZQER in the MicroStar Junior™ BGA-80 (ZQE) package - sharing identical pin assignments, power domains, and peripheral mappings. This allows direct substitution within the same PCB layout when adjusting flash size requirements without redesign.
