Texas Instruments MSP430F2002TPWR

Overview

MSP430F2002TPWR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 1KB Flash + 256B information memory, 128B RAM, and a 16-bit Timer_A with two capture/compare registers. It operates from 1.8 V to 3.6 V, achieves active-mode current of 220 µA at 1 MHz/2.2 V, and supports five power-saving modes including sub-1 µs wake-up from standby. It targets battery-powered sensor nodes requiring analog signal acquisition and local processing.

For engineers reviewing the MSP430F2002TPWR datasheet, MSP430F2002TPWR pinout, MSP430F2002TPWR application, or MSP430F2002TPWR equivalent, key selection criteria include its 10-bit ADC (200 ksps), USI supporting SPI/I²C, brownout detection, Spy-Bi-Wire on-chip emulation, and TSSOP-14 package compatibility with industrial temperature range (–40°C to 105°C).

Technical Context

The MSP430F2002TPWR 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 support for 32-kHz crystal or internal low-frequency oscillator.

It includes a 10-bit SAR ADC with internal reference, sample-and-hold, autoscan, and eight analog input channels (A0–A7). The Universal Serial Interface (USI) provides hardware-level SPI and I²C protocol support, while Timer_A2 delivers PWM, interval timing, and input capture with interrupt capability on overflow and each compare/capture event.

FAQ

What is the maximum operating frequency of the MSP430F2002TPWR?

The MSP430F2002TPWR features a factory-calibrated digitally controlled oscillator (DCO) with four precision frequency points: 1 MHz, 8 MHz, 12 MHz, and 16 MHz. While the DCO can be tuned beyond these points, TI specifies 16 MHz as the maximum guaranteed operating frequency under all conditions per the SLAS491I datasheet.

Does the MSP430F2002TPWR support in-system programming?

Yes, the MSP430F2002TPWR supports in-system programming via its Spy-Bi-Wire (SBW) interface using only two pins: TEST/SBWTCK and RST/NMI/SBWTDIO. This allows full Flash and information memory programming without removing the device from the PCB, and is compatible with TI's MSP-FET and open-source tools like naken_asm.

What ADC resolution and sampling rate does the MSP430F2002TPWR provide?

The MSP430F2002TPWR integrates a 10-bit successive approximation register (SAR) ADC capable of 200 ksps maximum sampling rate. It includes an internal reference, sample-and-hold circuit, and autoscan functionality across eight analog input channels (A0–A7), as confirmed in Section 1 of the SLAS491I datasheet.

Is the MSP430F2002TPWR pin-compatible with other devices in the MSP430F20xx family?

Yes, the MSP430F2002TPWR shares identical pinout and package (TSSOP-14) with all members of the MSP430F20xx series, including MSP430F2001TPWR, MSP430F2012TPWR, and MSP430F2013TPWR. This enables direct hardware reuse across variants differing only in Flash size, ADC type, or peripheral configuration.

What is the operating temperature range for the 'T' grade of MSP430F2002TPWR?

The 'T' suffix in MSP430F2002TPWR denotes the extended industrial temperature grade, rated from –40°C to +105°C. This is explicitly documented in Table 1 "Available Options" of the SLAS491I datasheet, distinguishing it from the standard 'I' grade (–40°C to +85°C).
