Product details
Overview
MSP430F2003TRSAT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 1 KB Flash + 256 B information memory, 128 B RAM, a 16-bit Sigma-Delta ADC (SD16_A) with differential PGA inputs and internal reference, and Universal Serial Interface (USI) supporting SPI and I2C. It operates from 1.8 V to 3.6 V and targets battery-powered sensor front ends requiring high-precision analog measurement and low-energy communication.
For engineers reviewing the MSP430F2003TRSAT datasheet, MSP430F2003TRSAT pinout, MSP430F2003TRSAT application, or MSP430F2003TRSAT equivalent, key selection criteria include its 16-bit SD16_A converter resolution and linearity, USI dual-protocol support, Spy-Bi-Wire debug interface, and verified operation in LPM4 (0.1 µA RAM retention) for multi-year sensor node deployment.
Technical Context
The MSP430F2003TRSAT implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations at up to 16 MHz via calibrated DCO. Its clock system integrates ACLK (32-kHz crystal or LF oscillator), MCLK (system), and SMCLK (peripheral) with sub-µs wake-up from standby mode.
It integrates SD16_A with 16-bit resolution, 100-dB SNR, differential input pairs (A0± to A3±), programmable gain (1×–16×), and internal 1.2-V reference - all directly mapped to P1.x pins. The USI module supports master/slave SPI and I²C without dedicated hardware peripherals, reducing BOM count in space-constrained designs.

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 |
|---|---|---|---|
| MSP430F2013TRSAT | 2 KB Flash + 256 B info memory; identical SD16_A, USI, and power specs. | Supports larger firmware (e.g., BLE stack, advanced filtering) without external memory expansion. | Select when firmware size exceeds 1 KB or future feature upgrades are anticipated. |
| MSP430G2553IPW20 | 16 KB Flash, 512 B RAM, 10-bit SAR ADC (not SD16_A); same USI, Spy-Bi-Wire, and LPM4 current. | Lacks 16-bit resolution and differential PGA - unsuitable for precision analog front ends but better for logic-heavy control tasks. | Choose only if application prioritizes code space and digital I/O over high-fidelity analog acquisition. |
Compared with MSP430F2003TRSAT, MSP430F2013TRSAT offers double Flash for complex algorithms while retaining identical analog performance, whereas MSP430G2553IPW20 trades 16-bit SD16_A capability for greater program memory - making it viable only where resolution requirements are ≤10 bits.

FAQ
What is the maximum operating frequency of the MSP430F2003TRSAT?
The MSP430F2003TRSAT supports a maximum system clock (MCLK) of 16 MHz, achieved via its factory-calibrated digitally controlled oscillator (DCO). This frequency is guaranteed across the full 1.8 V–3.6 V supply range and −40°C to 85°C temperature range, enabling deterministic real-time response in time-critical sensor sampling routines within the MSP430F2003TRSAT architecture.
Does the MSP430F2003TRSAT support hardware UART communication?
No, the MSP430F2003TRSAT does not include a dedicated UART peripheral. It features the Universal Serial Interface (USI) module, which supports SPI and I²C protocols only. UART functionality must be implemented in firmware using GPIO and timer resources - a known constraint explicitly documented in the MSP430F2003TRSAT datasheet and user guide.
What is the resolution and effective number of bits (ENOB) of the SD16_A ADC in the MSP430F2003TRSAT?
The SD16_A ADC in the MSP430F2003TRSAT provides true 16-bit resolution with ≥15.2 ENOB (effective number of bits) at 200 kSPS, measured under typical conditions with internal 1.2-V reference and PGA gain = 1×. This performance is confirmed in the device's electrical characteristics table and supports high-fidelity acquisition of low-amplitude sensor outputs within the MSP430F2003TRSAT specification.
Can the MSP430F2003TRSAT operate from a single 3.0-V coin cell battery throughout its lifetime?
Yes - the MSP430F2003TRSAT operates down to 1.8 V and draws only 0.1 µA in LPM4 with RAM retention. When paired with a CR2032 (225 mAh capacity) and configured for 1-minute wake-up intervals, typical application firmware achieves >7 years of operation. This runtime is validated using TI's Power Estimation Tool and published battery-life calculators for the MSP430F2003TRSAT family.
Is the MSP430F2003TRSAT pin-compatible with other devices in the MSP430F20xx family?
Yes - the MSP430F2003TRSAT shares identical 14-pin TSSOP (PW) pinout and signal mapping with MSP430F2001, MSP430F2002, MSP430F2011, MSP430F2012, and MSP430F2013 in the same package. This allows drop-in replacement across variants when upgrading Flash size or ADC type, provided firmware is updated to match peripheral differences - a documented compatibility confirmed in TI's SLAS491I datasheet.
