MSP430F5507IRGZR - 25MHz MCU, 32KB Flash, USB 2.0 | Texas Instruments
N.º da peça: MSP430F5507IRGZR ✓ AtivoMSP430F5507IRGZR Visão geral
An MSP430 microcontroller is a 16-bit RISC mixed-signal MCU platform from Texas Instruments that occupies the low-power and battery-aware tier of the embedded MCU hierarchy. Within that platform hierarchy the device sits as: MSP430F5xx -> MSP430F55xx (USB sub-family) -> MSP430F550x -> MSP430F5507. The 'F' prefix indicates in-system programmable Flash, the '5' indicates the F5xx generation with the CPUXV2 core and 25 MHz operation, and the trailing digits indicate memory size and feature set. The platform is widely used where deterministic low power and integrated analog matter more than raw MHz.
Key differentiating features include active-mode current of 180-195 uA/MHz at 3V, standby current of a few uA, a 1.4 V to 3.6 V wide core supply range (3.6 V absolute max), a true hardware USB 2.0 full-speed transceiver on-chip, a 10-bit successive-approximation ADC with up to 12 external input channels and sample-and-hold, a 32-bit hardware multiplier that accelerates DSP routines, and 31 general-purpose I/O pins. The internal oscillator removes an external crystal in many designs, and the DMA controller offloads data movement between peripherals and memory.
At the architectural level, the device uses TI's von-Neumann unified memory map with a 16-bit CPUXV2 core, a 3-stage pipeline, and four hardware multiplier operating modes. The integrated USB peripheral includes an on-chip PHY and pull-up resistors; code can implement HID, CDC, or vendor-class stacks directly. The 10-bit ADC is shared across eight internal and up to twelve external channels through the analog mux, while the DMA engine can stream ADC conversions directly into memory without CPU intervention.
Typical applications include USB human-interface devices such as keyboards, mice, and game controllers; portable medical and wellness peripherals; industrial sensor nodes and data loggers; low-power metering; and battery-powered instrumentation that needs an MCU + USB in a single chip. The wide I/O count and integrated analog make it a good fit when an external ADC or signal-conditioning chain would otherwise inflate the BOM.
When designing with this part, follow the TI MSP430x5xx Family User's Guide for power-management sequencing, especially the wake-from-LPM transitions and the USB suspend current budget. Reserve the exposed thermal pad for soldering to a ground copper pour to meet the package's thermal-resistance spec and to reduce EMI on the USB DP/DM lines. Use TI's USB Descriptor Tool and MSP430 USB Developers Package firmware to accelerate stack bring-up.

Aplicações típicas
MSP430F5507IRGZR é adequado para 6 aplicaçãos: USB Human-Interface Devices (HID), Portable Medical / Wellness Peripherals, Industrial Sensor Nodes and Data Loggers, Low-Power Metering and Energy Monitoring, Battery-Powered Instrumentation, USB-Connected Wearable / IoT Hubs.
USB Human-Interface Devices (HID)
The MSP430F5507IRGZR's integrated USB 2.0 full-speed peripheral with on-chip PHY makes it a strong fit for USB HID peripherals such as keyboards, mice, and game controllers. The device's 25 MHz CPUXV2 core comfortably runs HID report-rate polling loops while the 32 KB Flash holds a complete HID stack, descriptor table, and application code. The on-chip hardware multiplier accelerates matrix-scanning and gesture-decoding math without burdening the CPU. With active-mode current around 180-195 uA/MHz at 3 V and standby current in single-digit uA, the part is well-suited to USB-powered or battery-augmented designs that must meet USB suspend-current budgets.
Recomendado
Portable Medical / Wellness Peripherals
The MSP430F5507IRGZR's combination of 10-bit SAR ADC, low active current, and integrated USB suits portable medical and wellness peripherals such as heart-rate monitors, pulse oximeters, and connected thermometers. The ADC's sample-and-hold plus DMA streaming lets the firmware continuously digitize sensor output without CPU intervention, extending battery life. The on-chip USB PHY enables tether-free USB charging and data offload without an external transceiver. At 180-195 uA/MHz active and LPM3 currents in the single-digit uA, the part supports multi-day operation on a small Li-ion cell.
Recomendado
Industrial Sensor Nodes and Data Loggers
The MSP430F5507IRGZR fits industrial sensor nodes and low-rate data loggers that need deterministic low-power operation with occasional USB service access. The 10-bit ADC with up to 12 external inputs handles 4-20 mA loop, RTD, or bridge-sensor conditioning through an external mux, and the DMA engine can store ADC bursts directly into the 6 KB SRAM for batch upload over USB. The industrial operating temperature range of -40C to +85C, plus TI's long-term product support on the F55xx family, makes the part attractive for factory-floor and outdoor installations. The 31 GPIOs are sufficient for status LEDs, switch inputs, and SPI-muxed sensor busses.
Recomendado
Low-Power Metering and Energy Monitoring
The MSP430F5507IRGZR's integrated 10-bit ADC and DMA controller make it a good fit for low-power metering modules such as electricity, gas, and water monitors that occasionally connect via USB for service or firmware updates. The 25 MHz core can run metering math with the on-chip 32-bit hardware multiplier, while the LPM3/LPM4 low-power modes keep quiescent current in the single-digit uA so battery-backed meters can last their full lifetime. The on-chip USB PHY removes the need for an external transceiver, simplifying the meter-side BOM. The 32 KB Flash is sufficient for a complete metering stack with USB firmware-update capability.
Recomendado
Battery-Powered Instrumentation
The MSP430F5507IRGZR's wide 2.4 V to 3.6 V supply range and ultra-low LPM3/LPM4 currents make it an excellent fit for battery-powered instrumentation such as handheld oscilloscope probes, field calibration tools, and environmental monitors. The device's 25 MHz CPUXV2 core provides the throughput needed for FFT and FIR-style signal processing without sacrificing standby battery life. USB 2.0 full-speed on-chip enables tethered data export or firmware updates without draining battery when running on USB. The 32 KB Flash holds calibration tables, FFT kernels, and USB stack, while 6 KB SRAM holds signal buffers.
Recomendado
USB-Connected Wearable / IoT Hubs
The MSP430F5507IRGZR's combination of USB 2.0 full-speed on-chip, low active current, and small 7x7 mm VQFN package makes it ideal for USB-connected wearable and IoT hub designs. The device can act as a USB-CDC bridge between a host PC and a sensor fabric over SPI or I2C, while its DMA engine streams sensor data without CPU involvement. The 31 GPIOs and multiple serial interfaces are sufficient to bridge to BLE modules, displays, and external sensors. The wide -40C to +85C operating range and TI's long-term F55xx supply commitment suit consumer wearables that ship in high volume.

Notas de projeto
Estimated: with VBUS = 5 V and active-mode current at 195 uA/MHz at 3 V at 25 MHz, the MCU draws roughly 4.9 mA from DVCC during peak compute. Add a 1 uF plus 100 nF decoupling pair at each DVCC pin and a ferrite bead between VBUS and DVCC if the rail shares USB VBUS. Ensure USB suspend-current compliance by gating USB VBUS to DVCC through a TPS2051B-style power switch and configuring the F5507's USBIE bits for suspend.
Solder the exposed thermal pad of the 48-VQFN (RGZ) package to a continuous ground copper pour to meet the package's thermal-resistance specification and to provide a low-impedance ground reference for the USB DP/DM differential pair. Keep the DP/DM trace lengths matched within 150 mil and route them over a continuous ground plane; place the USB decoupling caps within 100 mil of pins 13-15.
Do not exceed 3.6 V on DVCC - the F55xx family is not 5 V tolerant on GPIO. The PUR pin enables the internal USB pull-up and must be tied to DVCC or driven through firmware for device-mode enumeration. The TEST/SBWTCK pin is used for Spy-Bi-Wire programming; leave it accessible for field updates. The F55xx silicon revision affects errata - check TI's SLAS945-style device errata sheet for your specific lot.
The 10-bit SAR ADC achieves its rated accuracy only with a low-impedance source; add an external op-amp buffer (e.g. MCP6072T-E/SN) for high-impedance sensors. Use the DMA controller to stream ADC conversions directly into RAM without CPU intervention to reduce digital switching noise coupling into the analog rail. Place AVCC and AVSS pins with their own filtered supply, derived from DVCC through a ferrite bead and decoupling capacitor pair.
