Product details
Overview
MSP430F5504IRGZT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, 8 KB flash, 4 KB + 2 KB RAM, 10-bit ADC (6 external + 2 internal channels), single USCI (UART/IrDA/SPI/I²C), four 16-bit timers, RTC, and hardware multiplier - designed for battery-powered sensor nodes and USB-connected data loggers.
For engineers reviewing the MSP430F5504IRGZT datasheet, MSP430F5504IRGZT pinout, MSP430F5504IRGZT application, or MSP430F5504IRGZT equivalent, key selection criteria include its 48-pin VQFN package, 1.8–3.6 V operation, sub-2 µA LPM3 current, USB endpoint count, ADC channel mapping, and USCI configuration flexibility via port mapping controller on P4.
Technical Context
The MSP430F5504IRGZT implements a 16-bit RISC CPUXV2 core with constant generators and unified clock system featuring FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management includes programmable LDO, SVS/SVM, brownout reset, and five low-power modes (LPM0–LPM4.5) with wake-up in <5 µs from standby.
Peripherals are mapped through a port mapping controller on P4, limiting simultaneous USCI function availability; only one USCI module (USCI_B1 or USCI_A1) is implemented, supporting either I²C/SPI or UART/IrDA/SPI depending on runtime configuration - not both concurrently on the same instance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPUXV2 with constant generators and 25-MHz max system clock - enables efficient C code execution and deterministic real-time response. |
| Flash / RAM | 8 KB flash + 4 KB + 2 KB RAM (USB SRAM usable as general-purpose when USB inactive) - supports firmware updates and dual-bank buffering for USB streaming. |
| ADC10_A | 10-bit SAR ADC with 200 ksps sampling, 6 external + 2 internal input channels, window comparator - suitable for multi-sensor analog front-end acquisition. |
| USB Interface | Full-speed USB 2.0 with integrated PHY, 3.3-V/1.8-V power system, USB-PLL, and 8 IN/8 OUT endpoints - enables direct host communication without external transceiver. |

FAQ
What is the maximum operating frequency of the MSP430F5504IRGZT?
The MSP430F5504IRGZT supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This allows high-speed instruction execution while maintaining ultra-low power consumption in active mode - critical for real-time sensor processing and USB packet handling without external clock sources.
Does the MSP430F5504IRGZT support USB device enumeration without external components?
Yes, the MSP430F5504IRGZT integrates a full-speed USB 2.0 PHY, USB-PLL, and dedicated 3.3-V/1.8-V power regulators (VUSB and V18), enabling complete USB device enumeration using only passive decoupling capacitors and standard USB termination. No external transceiver, level shifter, or crystal is required for basic HID or CDC operation.
How many analog input channels does the ADC10_A module support on the MSP430F5504IRGZT?
The ADC10_A module on the MSP430F5504IRGZT supports six external analog input channels (A0–A5 on P6.0–P6.5) and two internal sources (VeREF+ and VeREF− on P5.0/P5.1), totaling eight selectable inputs. Channel selection is software-controlled via ADC10CTL1 register, and conversion results are stored in ADC10MEM with window comparator functionality.
Can the MSP430F5504IRGZT operate from a single 1.8-V supply?
Yes, the MSP430F5504IRGZT operates across a supply range of 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including USB (with VUSB/V18 regulation), ADC operation, and 16-MHz DCO performance - verified in TI's recommended operating conditions table. This enables direct use with single-cell Li-ion or two-cell alkaline systems.
What debug interface does the MSP430F5504IRGZT support?
The MSP430F5504IRGZT supports both JTAG and Spy-Bi-Wire (SBW) debug interfaces via pins PJ.0–PJ.3 and TEST/SBWTCK (pin 47) and RST/NMI/SBWTDIO (pin 48). SBW uses a two-wire interface compatible with TI's MSP-FET and LaunchPad debuggers, reducing debug footprint versus full JTAG while retaining full flash programming and real-time debugging capability.
