Product details
Overview
MSP430FR2353TDBTR 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-channel 12-bit SAR ADC (200 ksps), four Smart Analog Combo (SAC-L3) modules, and dual eUSCI_A/eUSCI_B peripherals for UART/I²C/SPI. 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 MSP430FR2353TDBTR datasheet, MSP430FR2353TDBTR pinout, MSP430FR2353TDBTR application, or MSP430FR2353TDBTR equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 current (620 nA), SAC configurability (PGA ×1–×33), and 34 I/O count in compact TSSOP-38.
Technical Context
The MSP430FR2353TDBTR implements a 16-bit RISC CPU with 24-MHz DCO+FLL clock system, supporting ±1% accuracy at room temperature using on-chip reference. Its memory subsystem integrates unified FRAM (16KB + 512B) with ECC and configurable write protection, eliminating flash erase latency and enabling true atomic writes.
Digital peripherals include Timer_B3 (3 CCR), Timer_B7 (7 CCR), RTC counter, 16-bit CRC, MPY32 hardware multiplier, and Manchester codec (MFM). Analog subsystem comprises two enhanced comparators (eCOMP) with 6-bit DAC reference, and four SAC-L3 modules-each configurable as rail-to-rail OA, PGA, or 12-bit DAC-enabling flexible signal-chain integration without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2355TDBTR | 32KB program FRAM, 4KB RAM, full 12-channel ADC, 44 I/Os in same TSSOP-38 package | Higher memory and I/O count supports more complex firmware and additional sensors | Select when future firmware expansion or multi-sensor fusion is required; identical pinout and footprint enable drop-in upgrade. |
| MSP430FR2153TDBTR | No SAC modules; only two eCOMP; 10 ADC channels; same FRAM/RAM sizes and package | Lacks integrated programmable-gain amplification and DAC-based biasing-requires external analog components | Choose for cost-sensitive applications where SAC functionality is unnecessary and external signal conditioning is acceptable. |
Compared with MSP430FR2355TDBTR, the MSP430FR2353TDBTR trades 16KB FRAM and 2KB RAM for lower cost while retaining SAC and full ADC capability; versus MSP430FR2153TDBTR, it adds four SAC-L3 modules-enabling single-chip analog front-end integration previously requiring discrete op-amps and DACs.

FAQ
What is the maximum operating frequency of the MSP430FR2353TDBTR?
The MSP430FR2353TDBTR supports a maximum operating frequency of 24 MHz via its digitally controlled oscillator (DCO) with frequency-locked loop (FLL). This clock speed is achievable across the full operating voltage range (1.8 V to 3.6 V) and temperature range (–40°C to 105°C), and enables sub-10 µs wake-up from low-power modes. The DCO accuracy is ±1% at room temperature using the on-chip reference.
Does the MSP430FR2353TDBTR include hardware encryption or secure boot features?
No, the MSP430FR2353TDBTR does not include hardware encryption accelerators, secure boot, or tamper-detection circuitry. It relies on software-based security measures and external secure elements if cryptographic operations or firmware authentication are required. Its memory protection unit (MPU) supports basic FRAM write-protection configuration but does not provide AES, SHA, or key storage capabilities.
How many Smart Analog Combo (SAC) modules does the MSP430FR2353TDBTR integrate?
The MSP430FR2353TDBTR integrates four Smart Analog Combo (SAC-L3) modules. Each SAC can be independently configured as a programmable-gain amplifier (PGA) with gains from ×1 to ×33, a 12-bit DAC, or a general-purpose rail-to-rail operational amplifier. These modules share internal references and support offset/bias control via built-in 12-bit DACs-enabling flexible analog signal conditioning without external components.
What is the standby current consumption of the MSP430FR2353TDBTR in LPM3.5 mode?
In LPM3.5 mode-with the 32-kHz crystal oscillator active and SVS enabled-the MSP430FR2353TDBTR consumes 620 nA. This ultra-low quiescent current allows multi-year operation on coin-cell batteries in applications such as smoke detectors and wireless sensor nodes, while retaining RTC functionality and 32-byte backup memory operation.
Is the MSP430FR2353TDBTR pin-compatible with other devices in the MSP430FR235x family?
Yes, the MSP430FR2353TDBTR is pin-compatible with the MSP430FR2355TDBTR in the same TSSOP-38 (DBT) package. Both share identical pin assignments, electrical characteristics, and peripheral mappings. However, it is not pin-compatible with MSP430FR215x variants or different package types (e.g., LQFP-48 or VQFN-40), as pin functions and counts differ across packages and families.
