Texas Instruments MSP430F2003IPWR

Overview

MSP430F2003IPWR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 1 KB + 256 B flash memory, 128 B RAM, and a 16-bit Sigma-Delta A/D converter with differential PGA inputs and internal reference. It operates from 1.8 V to 3.6 V and supports five power-saving modes, enabling sub-1 µs wake-up from standby - ideal for battery-powered sensor front ends and portable measurement systems.

For engineers reviewing the MSP430F2003IPWR datasheet, MSP430F2003IPWR pinout, MSP430F2003IPWR application, or MSP430F2003IPWR equivalent, key selection criteria include its 16-bit SD16_A ADC resolution, Spy-Bi-Wire debug interface, TSSOP-14 package compatibility, and integrated USI supporting SPI/I²C for sensor data aggregation in constrained embedded designs.

Technical Context

The MSP430F2003IPWR implements a 16-bit RISC CPU with constant generators and six operating modes (AM, LPM0–LPM4), where LPM4 draws only 0.1 µA with RAM retention. Its basic clock module integrates a digitally controlled oscillator (DCO) calibrated to ±1% at 1/8/12/16 MHz, plus support for 32-kHz crystal or internal low-frequency oscillator.

It features a 16-bit Timer_A2 with two capture/compare registers, universal serial interface (USI) for synchronous SPI or I²C communication, and a dedicated 16-bit sigma-delta ADC (SD16_A) with eight differential analog input channels, programmable gain amplifier, and internal reference - all mapped to a fixed 14-pin TSSOP footprint.

FAQ

What is the maximum clock frequency supported by the MSP430F2003IPWR?

The MSP430F2003IPWR supports an internal digitally controlled oscillator (DCO) calibrated to four factory-set frequencies: 1 MHz, 8 MHz, 12 MHz, and 16 MHz, with ±1% accuracy. External clock sources up to 16 MHz are also accepted via XIN/P2.6. The MSP430F2003IPWR does not support higher frequencies - exceeding 16 MHz may cause timing violations or instability.

Does the MSP430F2003IPWR include hardware UART support?

No, the MSP430F2003IPWR does not include a hardware UART peripheral. It features a Universal Serial Interface (USI) module supporting SPI and I²C protocols only. UART functionality must be implemented in software (bit-banged) or added externally. For native UART, consider TI's MSP430G2xx or MSP430FRxx families - the MSP430F2003IPWR is optimized for low-power analog sensing, not serial host interfacing.

What ADC resolution and architecture does the MSP430F2003IPWR provide?

The MSP430F2003IPWR integrates a 16-bit Sigma-Delta A/D converter (SD16_A) with differential programmable-gain amplifier (PGA) inputs, internal reference, and eight selectable analog input channels. This architecture delivers high-resolution, low-noise conversion essential for precision sensor applications - distinct from the 10-bit SAR ADC in the MSP430F20x2 family. The SD16_A is confirmed for MSP430F20x3 devices including MSP430F2003IPWR.

Is the MSP430F2003IPWR pin-compatible with other MSP430F20xx variants in TSSOP-14?

Yes, the MSP430F2003IPWR shares identical pinout and electrical characteristics with all MSP430F20xx devices in the 14-pin TSSOP (PW) package, including MSP430F2001IPWR, MSP430F2002IPWR, MSP430F2011IPWR, MSP430F2012IPWR, and MSP430F2013IPWR. Function mapping differs per variant (e.g., comparator vs. ADC vs. USI), but PCB layout and footprint are fully interchangeable.

What debug interface does the MSP430F2003IPWR use, and what pins are required?

The MSP430F2003IPWR uses the Spy-Bi-Wire (SBW) interface - a 2-pin subset of JTAG - for programming and debugging. It requires only TEST/SBWTCK (pin 11) and RST/NMI/SBWTDIO (pin 10) connected to a compatible debugger (e.g., MSP-FET or LaunchPad). No additional pins or signals are needed, making SBW ideal for space-constrained designs where full 4-pin JTAG is impractical.
