Product details
Overview
MSP430FR4133IG48R from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 15.5 KB FRAM (15 KB program + 512 B info), 2 KB RAM, integrated LCD driver supporting up to 4×24 or 8×20 segments, and a 10-bit 200 ksps ADC with internal 1.5-V reference - deployed in battery-powered smart meters and portable medical monitors.
For engineers reviewing the MSP430FR4133IG48R datasheet, MSP430FR4133IG48R pinout, MSP430FR4133IG48R application, or MSP430FR4133IG48R equivalent, key selection criteria include its 48-pin TSSOP package, 15 nA shutdown current (LPM4.5), capacitive touch I/O capability across all pins, and dual eUSCI modules supporting UART/I²C/SPI for sensor interface and display control.
Technical Context
The MSP430FR4133IG48R integrates a 16-MHz digitally controlled oscillator (DCO) with FLL for ±1% accuracy at room temperature, paired with REFO (32 kHz), VLO (10 kHz), MODCLK, and external XT1 crystal support - enabling flexible clock tree configuration for low-power real-time operation. Its power management module supports six low-power modes including LPM3.5 (RTC + LCD active) and LPM4.5 (15 nA shutdown).
It features two Timer_A3 peripherals (TA0/TA1), each with three capture/compare registers (CCR0–CCR2), where CCR1/CCR2 are externally accessible; one dedicated RTC counter; CRC16 engine; and IR modulation logic - all operating within the same unified FRAM memory space with ECC protection and configurable write lock.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR4133IPM | 64-pin LQFP package; 60 I/Os; supports 4×36/8×32 LCD; higher pin count and larger footprint | Used where expanded I/O, larger LCD, or additional analog channels are required | Select when board layout allows larger package and more peripherals are needed beyond MSP430FR4133IG48R's 44 I/Os and 4×24 LCD support |
| MSP430FR4132IG48 | Same 48-pin TSSOP package but with 8 KB FRAM + 1 KB RAM - reduced memory capacity | Suitable for simpler metering or control functions without extensive data logging or firmware complexity | Choose for cost-sensitive designs where 15 KB FRAM and 2 KB RAM of MSP430FR4133IG48R are unnecessary |
Compared with MSP430FR4133IPM, the MSP430FR4133IG48R offers identical core functionality in a smaller 48-pin TSSOP package with fewer I/Os and reduced LCD segment count - ideal for space-constrained metering. Against MSP430FR4132IG48, it delivers 88% more FRAM and double the RAM, enabling richer firmware and longer data retention without external storage.

FAQ
What is the maximum operating frequency of the MSP430FR4133IG48R?
The MSP430FR4133IG48R operates at up to 16 MHz using its on-chip digitally controlled oscillator (DCO) with frequency-locked loop (FLL). This frequency is achievable across the full recommended supply voltage range (1.8 V to 3.6 V) and supports real-time signal processing and fast peripheral response in applications like smart meters and medical monitors. The DCO maintains ±1% accuracy at room temperature with the internal reference.
Does the MSP430FR4133IG48R support hardware-based capacitive touch sensing?
Yes, the MSP430FR4133IG48R supports hardware capacitive touch sensing on all 44 general-purpose I/O pins via its integrated CapTIvate™-compatible CSIO module. No external components are required - the MCU performs auto-calibration, noise filtering, and proximity detection in firmware. This capability is confirmed in Section 7.2 and Figure 4-1 of the official datasheet, enabling robust touch interfaces in thermostats and remote controls.
How many LCD segments does the MSP430FR4133IG48R support?
The MSP430FR4133IG48R supports up to 4×24 or 8×20 segment LCD configurations - totaling 96 segments - as specified in Table 6-1 and Section 1 Features. This is lower than the 64-pin variant (which supports 4×36/8×32) due to reduced pin count in the 48-pin TSSOP package. The LCD driver includes an on-chip charge pump and software-configurable SEG/COM assignment per pin.
What debug interface does the MSP430FR4133IG48R use?
The MSP430FR4133IG48R uses the Spy-Bi-Wire (SBW) interface for programming and debugging, implemented on pins RST/NMI/SBWTDIO (pin 16) and TEST/SBWTCK (pin 15). This 2-wire interface is fully compatible with TI's MSP-FET and LaunchPad development tools. JTAG is not supported on this device - SBW is the sole standardized debug protocol, as documented in Sections 9.6 and 7.2 of the datasheet.
Is the MSP430FR4133IG48R pin-compatible with other members of the FR413x family?
No, the MSP430FR4133IG48R is not pin-compatible with the 64-pin LQFP or 56-pin TSSOP variants - it uses a unique 48-pin TSSOP (DGG) footprint with 44 I/Os. While functional register mapping and firmware are largely compatible across the FR413x family, physical layout requires redesign when switching between package types. Pin compatibility exists only within the same package variant (e.g., MSP430FR4132IG48 shares the same pinout but differs in memory size).
