Product details
Overview
MSP430FR4133IG56 from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 56-pin TSSOP package, featuring 15.5KB nonvolatile FRAM (15KB program + 512B info), 2KB RAM, 8-channel 10-bit ADC, and integrated LCD driver supporting up to 4×30 or 8×26 segments - deployed in battery-powered smart meters and portable medical monitors.
For engineers reviewing the MSP430FR4133IG56 datasheet, MSP430FR4133IG56 pinout, MSP430FR4133IG56 application, or MSP430FR4133IG56 equivalent, key selection criteria include standby current <1 µA with RTC+LCD active, 15 nA shutdown mode, capacitive touch I/O on all pins, and dual eUSCI modules supporting UART/I²C/SPI for sensor interface and display control.
Technical Context
The MSP430FR4133IG56 integrates a 16-MHz digitally controlled oscillator (DCO) with FLL, ±1% accuracy at room temperature, and multiple clock sources including REFO (32 kHz), VLO (10 kHz), MODCLK, and external XT1 crystal - enabling rapid wake-up (<10 µs) from LPM3.5 while sustaining LCD and RTC operation. Its memory architecture unifies FRAM for code, constants, and data storage with ECC protection and 10¹⁵ write endurance.
Peripherals include two Timer_A3 modules (each with three capture/compare registers), CRC16 engine, IR modulation logic, and dual eUSCI blocks: eUSCI_A0 supports UART/IrDA/SPI; eUSCI_B0 supports SPI/I²C. All 52 GPIOs are capacitive-touch-capable and support interrupt-driven wake-up from low-power modes.

FAQ
What is the maximum LCD segment count supported by the MSP430FR4133IG56?
The MSP430FR4133IG56 supports up to 4×30 or 8×26 segment LCD configurations - fewer than the 64-pin variant due to reduced I/O count in the 56-pin TSSOP package. This limitation arises from dedicated LCD pin allocation and internal multiplexing constraints, not driver capability. The charge pump remains fully functional for bias generation in low-power modes.
Does the MSP430FR4133IG56 include hardware-based capacitive touch sensing?
No - the MSP430FR4133IG56 does not contain dedicated capacitive touch hardware. However, all 52 GPIOs support software-based capacitive touch sensing using built-in comparator and timer peripherals, enabling button, slider, and proximity detection without external ICs. TI provides CapTIvate™ software libraries optimized for this implementation on MSP430FR4133IG56.
What is the minimum supply voltage for reliable operation of the MSP430FR4133IG56?
The MSP430FR4133IG56 operates reliably from 1.8 V to 3.6 V. Below 1.8 V, the supply voltage supervisor (SVS) may trigger reset depending on configured thresholds. The datasheet specifies 1.8 V as the absolute minimum under recommended operating conditions - sustained operation below this level risks FRAM corruption, ADC inaccuracy, and clock instability.
Can the MSP430FR4133IG56 use an external 32.768-kHz crystal for RTC operation?
Yes - the MSP430FR4133IG56 supports external 32-kHz crystal oscillation via XIN (pin 13) and XOUT (pin 12) in the TSSOP-56 package. This configuration provides high-accuracy RTC timing essential for utility metering and medical timestamping. Load capacitance and PCB layout must follow TI's crystal oscillator design guidelines to ensure stable startup and low jitter.
How many independent serial interfaces does the MSP430FR4133IG56 support?
The MSP430FR4133IG56 supports two independent enhanced USCI modules: eUSCI_A0 (configurable as UART, IrDA, or SPI) and eUSCI_B0 (configurable as SPI or I²C). Both operate concurrently with separate clock domains and interrupt vectors, enabling simultaneous communication with display, sensor, and wireless modules without CPU arbitration overhead.
