FAQ
What is the maximum LCD segment count supported by the MSP430FR4133IG48?
The MSP430FR4133IG48 supports up to 4×24 or 8×20 segment LCD configurations, as specified in TI's official device comparison table. This is less than the 64-pin variant's 4×36/8×32 capability due to reduced COM/SEG pin count in the 48-pin TSSOP package. The LCD driver includes an on-chip charge pump enabling operation in LPM3.5 mode.
Does the MSP430FR4133IG48 include hardware support for capacitive touch sensing?
Yes, the MSP430FR4133IG48 includes dedicated capacitive touch sensing (CTS) hardware. All 44 GPIO pins are configurable as capacitive touch I/Os, allowing implementation of touch buttons, sliders, or proximity detection without external components. This capability is documented in Section 1 of the SLAS865F datasheet and confirmed in the functional block diagram.
What are the key power consumption figures for the MSP430FR4133IG48 in low-power modes?
The MSP430FR4133IG48 achieves 15 nA in LPM4.5 (shutdown), <1 µA in LPM3.5 (RTC + LCD active), and 126 µA/MHz in active mode at 3 V. These values are measured under recommended operating conditions and reflect the device's optimized ULP architecture - critical for battery-operated applications like smart meters and medical monitors.
Is the MSP430FR4133IG48 pin-compatible with other members of the MSP430FR413x family in the same package?
Yes, the MSP430FR4133IG48 shares identical pinout and footprint with MSP430FR4132IG48 and MSP430FR4131IG48 in the 48-pin TSSOP (DGG) package. Differences are limited to memory size (FRAM/RAM) and do not affect electrical pin behavior, peripheral mapping, or PCB layout - enabling firmware-only differentiation across variants.
What communication interfaces does the MSP430FR4133IG48 support?
The MSP430FR4133IG48 integrates eUSCI_A0 supporting UART, IrDA, and SPI, and eUSCI_B0 supporting SPI and I²C. These are hardware-peripheral modules with independent clocking and DMA-ready registers. No external transceivers are needed for basic serial communication, and both modules operate across all active and low-power modes where clocks are enabled.
