Product details
Overview
MSP430F2002TN from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller featuring 1KB + 256B flash memory, 128B RAM, and a 16-bit Timer_A with two capture/compare registers. It operates from 1.8 V to 3.6 V, supports Spy-Bi-Wire on-chip emulation, and targets battery-powered sensor systems requiring sub-1µs wake-up and analog signal acquisition.
For engineers reviewing the MSP430F2002TN datasheet, MSP430F2002TN pinout, MSP430F2002TN application, or MSP430F2002TN equivalent, key selection criteria include its 10-bit 200-ksps ADC with internal reference and autoscan, USI supporting SPI/I²C, brownout detection, and five power-saving modes - all in a 14-pin PDIP (TN) package rated for –40°C to 105°C operation.
Technical Context
The MSP430F2002TN implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its basic clock module integrates a digitally controlled oscillator (DCO) calibrated to ±1% at 1 MHz, 8 MHz, 12 MHz, and 16 MHz, plus internal low-frequency and external 32-kHz crystal support.
It features a 10-bit successive-approximation ADC (ADC10) with eight analog inputs, internal reference (1.5 V/2.5 V), sample-and-hold, and DMA-triggered autoscan. The Universal Serial Interface (USI) provides hardware-configurable SPI or I²C communication without dedicated peripheral clocks.

FAQ
What is the maximum operating frequency of the MSP430F2002TN's DCO?
The MSP430F2002TN's digitally controlled oscillator (DCO) is factory-calibrated to operate at up to 16 MHz with ±1% accuracy across voltage and temperature. This maximum frequency is achieved using CALBC1_16MHZ and CALDCO_16MHZ values stored in information memory segment A, and enables full-speed execution of the 16-bit RISC core without external crystals.
Does the MSP430F2002TN support hardware UART communication?
No, the MSP430F2002TN does not include a dedicated UART peripheral. It features a Universal Serial Interface (USI) module that supports only SPI and I²C protocols in hardware. UART functionality must be implemented in software using Timer_A outputs and GPIO pins, which increases CPU load and limits baud rate flexibility compared to hardware UART solutions.
Can the MSP430F2002TN's ADC10 perform conversions while the device is in LPM3 mode?
Yes, the MSP430F2002TN's ADC10 can operate autonomously in LPM3 mode when ACLK remains active (e.g., driven by a 32-kHz crystal). The ADC10 control logic and reference remain powered, allowing trigger-based conversions (e.g., timer compare match) and interrupt-driven data handling without waking the CPU - reducing average system current significantly.
What is the purpose of the TEST/SBWTCK pin on the MSP430F2002TN?
The TEST/SBWTCK pin on the MSP430F2002TN serves as the Spy-Bi-Wire test clock input during programming and debug sessions. When pulled high during power-up, it enables the two-wire debug interface for flash programming and real-time emulation. In normal operation, it must be held high externally to prevent accidental entry into test mode, as floating or low states may disrupt device startup.
How many analog input channels does the MSP430F2002TN's ADC10 support?
The MSP430F2002TN's ADC10 supports eight analog input channels (A0 through A7), mapped directly to P1.0 through P1.7. All channels are accessible via the ADC10CTL1 register's INCHx bits, and the autoscan feature allows sequential conversion across any contiguous subset without CPU intervention - ideal for multi-sensor polling.
