Product details

Overview

MSP430F2003TPW from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 1 KB + 256 B flash, 128 B RAM, a 16-bit Sigma-Delta ADC (SD16_A) with differential PGA inputs and internal reference, USI supporting SPI/I²C, and operation across –40°C to 105°C. It targets battery-powered sensor front ends requiring high-precision analog measurement and low-energy wireless telemetry.

For engineers reviewing the MSP430F2003TPW datasheet, MSP430F2003TPW pinout, MSP430F2003TPW application, or MSP430F2003TPW equivalent, key selection criteria include its 16-bit sigma-delta ADC resolution, differential analog input capability, Spy-Bi-Wire debug interface, TSSOP-14 package footprint, and extended temperature grade for industrial sensing deployments.

Technical Context

The MSP430F2003TPW 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 ultra-fast wake-up (<1 µs) from LPM4.

It integrates SD16_A - a 16-bit sigma-delta ADC with programmable gain amplifier (PGA), differential input pairs (A0±, A1±, A2±, A3±), internal 1.2-V reference, and oversampling support - alongside Timer_A2 (two capture/compare registers), USI (SPI/I²C), and brownout detection. All peripherals are memory-mapped and accessible via standard instructions.

FAQ

What is the maximum operating frequency of the MSP430F2003TPW?

The MSP430F2003TPW supports a maximum CPU clock frequency of 16 MHz, achieved via its factory-calibrated digitally controlled oscillator (DCO). This frequency is guaranteed across the full –40°C to +105°C temperature range and 1.8–3.6 V supply, with four internal calibration points ensuring ±1% accuracy without external components. The MSP430F2003TPW does not require an external crystal to reach 16 MHz.

Does the MSP430F2003TPW support differential analog measurements?

Yes, the MSP430F2003TPW supports true differential analog measurements via its SD16_A 16-bit sigma-delta ADC, which provides four dedicated differential input pairs: A0±, A1±, A2±, and A3±. Each pair accepts signals referenced to the internal 1.2-V reference or external VREF, enabling high common-mode rejection ratio (CMRR) and elimination of external instrumentation amplifiers in bridge or thermocouple interfaces.

What debug interface does the MSP430F2003TPW use?

The MSP430F2003TPW uses the Spy-Bi-Wire (SBW) interface - a 2-pin variant of JTAG - for in-circuit debugging and flash programming. It requires only RST/NMI/SBWTDIO and TEST/SBWTCK pins, eliminating the need for full 4-pin JTAG headers. This interface supports full-speed emulation, hardware breakpoints, flash erase/write, and is compatible with TI's MSP-FET and all major IDEs including Code Composer Studio.

Is the MSP430F2003TPW pin-compatible with other devices in the MSP430F20xx family?

Yes, the MSP430F2003TPW is pin-compatible with all TSSOP-14 variants in the MSP430F20xx family, including MSP430F2001TPW, MSP430F2002TPW, MSP430F2011TPW, MSP430F2012TPW, and MSP430F2013TPW. They share identical pin functions, electrical characteristics, and package dimensions, allowing drop-in replacement where flash size, ADC type, or USI capability align with design requirements.

What is the lowest power consumption mode of the MSP430F2003TPW?

The lowest power consumption mode of the MSP430F2003TPW is Low-Power Mode 4 (LPM4), which disables all clocks including ACLK, and retains only RAM contents. In this mode, the device draws just 0.1 µA at 2.2 V and 25°C - verified across the full –40°C to +105°C operating range. Wake-up from LPM4 to active mode occurs in less than 1 µs via any enabled interrupt source.
