Product details
Overview
MSP430F2001TPW 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 integrates an analog comparator (Comparator_A+), brownout protection, and Spy-Bi-Wire on-chip emulation. Designed for battery-powered sensor nodes and portable measurement systems, it operates from 1.8 V to 3.6 V and supports five power-saving modes.
For engineers reviewing the MSP430F2001TPW datasheet, MSP430F2001TPW pinout, MSP430F2001TPW application, or MSP430F2001TPW equivalent, key selection criteria include its 14-pin TSSOP (PW) package, absence of ADC or USI peripherals, verified 1 µs wake-up from LPM3/LPM4, and compatibility with TI's MSP430x2xx toolchain and Code Composer Studio.
Technical Context
The MSP430F2001TPW implements a 16-bit RISC CPU with seven addressing modes and constant generators for high code efficiency. Its basic clock module delivers ACLK (from internal LF oscillator or external 32-kHz crystal), MCLK (DCO-derived up to 16 MHz), and SMCLK - all digitally controlled and calibrated at factory for ±1% accuracy across four frequencies (1/8/12/16 MHz).
It uses a single 8-bit I/O port (P1) with individually configurable pullup/pulldown resistors and edge-selectable interrupts on all eight pins, plus two dedicated P2 pins (XIN/XOUT) supporting crystal or digital clock input. The analog comparator features eight-channel input multiplexing (CA0–CA7), programmable hysteresis, and output routing to P1.3 or P1.7.

FAQ
What is the maximum operating frequency of the MSP430F2001TPW?
The MSP430F2001TPW supports a maximum system clock (MCLK) of 16 MHz, achieved using the factory-calibrated digitally controlled oscillator (DCO). This frequency is guaranteed across the full industrial temperature range (–40°C to +105°C) and supply voltage (1.8 V to 3.6 V), with no external crystal required due to internal calibration data stored in Flash Segment A.
Does the MSP430F2001TPW include an analog-to-digital converter (ADC)?
No, the MSP430F2001TPW does not include an ADC. It belongs to the MSP430F20x1 family variant, which features only the analog comparator (Comparator_A+) - not the 10-bit ADC10 (found in F20x2) or 16-bit SD16_A (found in F20x3). For ADC functionality, consider the pin-compatible MSP430F2002TPW or MSP430F2003TPW.
What debug interface does the MSP430F2001TPW support?
The MSP430F2001TPW supports the Spy-Bi-Wire (SBW) interface using two pins: RST/NMI/SBWTDIO (pin 10) and TEST/SBWTCK (pin 11). This two-wire protocol is fully compatible with TI's MSP-FET and LaunchPad development tools, enabling full flash programming, real-time debugging, and breakpoint execution without requiring a full 4-pin JTAG header.
Can the MSP430F2001TPW operate without an external crystal?
Yes, the MSP430F2001TPW can operate entirely without an external crystal. Its basic clock module includes an internal digitally controlled oscillator (DCO) with four factory-calibrated frequencies (1/8/12/16 MHz) accurate to ±1%. ACLK can also use the internal very-low-power LF oscillator, eliminating all external timing components for many low-accuracy timing applications.
What is the purpose of the CAOUT pin on the MSP430F2001TPW?
The CAOUT signal on the MSP430F2001TPW is the output of the integrated analog comparator (Comparator_A+). It appears on P1.3 and/or P1.7 depending on configuration and can drive GPIO interrupts or feed into Timer_A for event-triggered timing. This allows zero-latency threshold detection - for example, waking the CPU immediately when a sensor voltage crosses a setpoint - without CPU polling or ADC conversion overhead.
