Product details
Overview
MSP430F5659IZQWR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, 512 KB flash, 64 KB + 2 KB RAM, 12-bit ADC (200 ksps, 16 channels), dual 12-bit DACs, and 74 GPIO pins in a 113-ball MicroStar Junior™ BGA package. It targets battery-powered sensor nodes and portable instrumentation requiring RTC backup, LCD drive, and fast wake-up (3 µs) from LPM3.
For engineers reviewing the MSP430F5659IZQWR datasheet, MSP430F5659IZQWR pinout, MSP430F5659IZQWR application, or MSP430F5659IZQWR equivalent, key selection criteria include USB integration without external PHY, LPM3.5 RTC operation at 1.1 µA, 160-segment LCD driver capability, hardware multiplier support for 32-bit operations, and compatibility with TI's MSP430F5xx toolchain and development ecosystem.
Technical Context
The MSP430F5659IZQWR implements a 16-bit RISC CPUXV2 core with constant generators and 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 architecture includes an integrated LDO with programmable core voltage, supply supervision, and brownout detection.
Peripheral integration centers on three USCIs (two UART/IrDA/SPI-capable, one I²C/SPI-capable), four 16-bit timers (TA0 with 5 CC registers; TA1/TA2 with 3 each; TB0 with 7), 6-channel DMA, and USB 2.0 full-speed interface with integrated 3.3-V/1.8-V power system and USB-PLL - all operating under five low-power modes optimized for sub-µA standby and shutdown currents.

FAQ
What is the maximum operating frequency of the MSP430F5659IZQWR?
The MSP430F5659IZQWR supports a maximum system clock frequency of 20 MHz, achieved using the integrated FLL with either internal DCO or external crystal sources (XT1 or XT2). This frequency enables real-time signal processing and high-throughput USB communication while maintaining ultra-low-power operation in active mode (295 µA/MHz at 3.0 V).
Does the MSP430F5659IZQWR support USB device mode only, or can it act as a USB host?
The MSP430F5659IZQWR implements a full-speed USB 2.0 device controller with integrated PHY and supports only USB device mode - not host mode. It complies with USB 2.0 specification and supports standard classes including CDC, HID, and MSC. The MSP430F5659IZQWR does not include OTG capability or host stack hardware.
What is the pin-compatible alternative to MSP430F5659IZQWR in LQFP package?
The MSP430F5659IPZ is the direct pin-compatible alternative in 100-pin LQFP (14 mm × 14 mm) package. It shares identical flash (512 KB), RAM (64 KB + 2 KB), peripherals (USB, ADC12_A, DAC12_A, USCI, timers), and electrical specifications with the MSP430F5659IZQWR - differing only in package type and thermal characteristics.
Can the MSP430F5659IZQWR operate from a single 3.0-V supply without external regulators?
Yes, the MSP430F5659IZQWR operates from a single 3.0-V supply. Its integrated LDO generates a regulated core voltage (VCORE), and DVCC/AVCC rails are internally derived. External decoupling (100 nF ceramic per supply pin) is required, but no external regulator IC is needed - simplifying power design for compact battery-powered systems.
What is the RTC backup capability of the MSP430F5659IZQWR in LPM3.5 mode?
In LPM3.5 mode, the MSP430F5659IZQWR maintains RTC operation using a 32-kHz crystal while consuming only 1.1 µA at 3.0 V. The RTC_B module retains calendar/time registers and alarm functionality with battery backup path enabled - allowing accurate timekeeping during main power removal, critical for energy metering and data-logging applications.
