Texas Instruments MSP430FR2153TDBTR

Overview

MSP430FR2153TDBTR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in 38-pin TSSOP package, featuring 16KB program FRAM + 512B data FRAM, 2KB RAM, 12-bit SAR ADC (12-channel, 200 ksps), two enhanced comparators with integrated 6-bit DAC, and dual eUSCI_A (UART/IrDA/SPI) and eUSCI_B (SPI/I²C) modules. It operates from 1.8 V to 3.6 V across –40°C to 105°C and targets battery-powered sensor signal conditioning and industrial monitoring.

For engineers reviewing the MSP430FR2153TDBTR datasheet, MSP430FR2153TDBTR pinout, MSP430FR2153TDBTR application, or MSP430FR2153TDBTR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 current (620 nA), 24-MHz DCO accuracy (±1% at room temperature), and I/O count (34 pins) in compact TSSOP-38.

Technical Context

This MCU implements a 16-bit RISC CPU with constant generator and 24-MHz digitally controlled oscillator (DCO) locked via FLL to internal or external references. Its power management module supports six low-power modes, including LPM3.5 (620 nA with RTC active) and LPM4.5 (42 nA shutdown), enabled by SVS monitoring of DVCC.

The analog subsystem integrates a 12-bit SAR ADC with programmable sample-and-hold, two eCOMP units (one with 100-ns response, one with 1.5-µA low-power mode), and shared internal voltage references (1.5/2.0/2.5 V). Unlike MSP430FR235x variants, MSP430FR2153TDBTR excludes Smart Analog Combo (SAC) modules.

FAQ

What is the maximum operating frequency of the MSP430FR2153TDBTR?

The MSP430FR2153TDBTR features a 24-MHz digitally controlled oscillator (DCO) with frequency-locked loop (FLL), enabling a maximum CPU clock of 24 MHz. This frequency is achievable across the full operating voltage range (1.8 V to 3.6 V) and temperature range (–40°C to 105°C), with ±1% accuracy at room temperature when referenced to the internal REFO oscillator. The MSP430FR2153TDBTR maintains deterministic timing for real-time sensor sampling and control loops without external crystal dependency.

Does the MSP430FR2153TDBTR support hardware debugging?

Yes, the MSP430FR2153TDBTR supports hardware debugging via the Spy-Bi-Wire (SBW) interface using the SBWTDIO and SBWTCK pins. This 2-wire interface enables full-speed emulation, breakpoint setting, register inspection, and flash programming through TI's MSP-FET and compatible debug probes. No JTAG header is required, reducing PCB footprint. The MSP430FR2153TDBTR also supports ROM-based bootloader (BSL) for field firmware updates over UART or I²C, eliminating need for physical debugger access after deployment.

How many analog input channels does the MSP430FR2153TDBTR ADC support?

The MSP430FR2153TDBTR integrates a 12-bit successive approximation register (SAR) ADC with up to 12 single-ended input channels (A0–A11), mapped across multiple GPIO ports. All channels share programmable sample-and-hold and selectable internal references (1.5 V, 2.0 V, or 2.5 V). The ADC achieves 200 ksps throughput and supports configurable conversion triggers (timer, software, or comparator output), making it suitable for multi-sensor polling in smoke detectors or battery monitors. Differential mode is not supported - only single-ended acquisition is implemented.

Is the MSP430FR2153TDBTR pin-compatible with other devices in the MSP430FR215x family?

Yes, the MSP430FR2153TDBTR is pin-compatible with other TSSOP-38 variants in the MSP430FR215x family, including MSP430FR2155TDBTR. Both share identical pin count, pinout assignment, electrical characteristics, and package dimensions (9.7 mm × 4.4 mm). This allows direct substitution for increased FRAM/RAM capacity without PCB changes. However, it is not pin-compatible with LQFP-48, VQFN-40, or VQFN-32 variants due to differing pin counts and layouts - those require board redesign.

What is the endurance rating of the FRAM in the MSP430FR2153TDBTR?

The FRAM in the MSP430FR2153TDBTR is rated for 10¹⁵ write cycles - orders of magnitude higher than EEPROM or flash memory. This endurance applies to both program and data FRAM segments (16KB + 512B) and is guaranteed across the full operating temperature range (–40°C to 105°C). Unlike flash, FRAM writes occur at bus speed with no erase latency, enabling real-time logging of transient events (e.g., fault timestamps in circuit breakers) without wear leveling or block management overhead. The MSP430FR2153TDBTR FRAM also includes built-in error correction code (ECC) for single-bit error correction and detection.
