Texas Instruments MSP430F2001TRSAR

Overview

MSP430F2001TRSAR from Texas Instruments is an ultra-low-power 16-bit RISC 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 requiring sub-1µs wake-up and <0.1µA off-mode retention.

For engineers reviewing the MSP430F2001TRSAR datasheet, MSP430F2001TRSAR pinout, MSP430F2001TRSAR application, or MSP430F2001TRSAR equivalent, key selection criteria include its 14-pin TSSOP package, -40°C to 105°C extended temperature rating, 1.8–3.6V supply range, and absence of ADC or USI peripherals - distinguishing it from F20x2/F20x3 family members.

Technical Context

The MSP430F2001TRSAR implements a 16-bit 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), SMCLK, and MCLK - with factory-calibrated DCO frequencies up to 16 MHz enabling sub-1µs active-mode wake-up from LPM4.

It features one 8-bit I/O port (P1) with individually configurable pullup/pulldown resistors and edge-selectable interrupts, plus two P2 pins (XIN/XOUT) supporting crystal or digital clock input. The integrated Comparator_A+ supports eight-channel analog input multiplexing and rail-to-rail operation, but lacks dedicated voltage reference buffers or DAC output.

FAQ

What is the maximum operating frequency of the MSP430F2001TRSAR?

The MSP430F2001TRSAR supports a maximum system clock (MCLK) of 16 MHz, achieved via its factory-calibrated digitally controlled oscillator (DCO). This frequency is confirmed in the SLAS491I datasheet Section 1 "Features" and Table 11 "DCO Calibration Data", where CALBC1_16MHZ and CALDCO_16MHZ values are provided in info memory segment A. The DCO stabilizes in less than 1 µs, enabling rapid transitions from low-power modes.

Does the MSP430F2001TRSAR include an analog-to-digital converter (ADC)?

No, the MSP430F2001TRSAR does not include an ADC. It belongs to the MSP430F20x1 family variant, which integrates only the Comparator_A+ module - not the 10-bit ADC10 (found in F20x2) or 16-bit SD16_A (found in F20x3). This is explicitly stated in the "DESCRIPTION" section of SLAS491I: "The MSP430F20x1 has a versatile analog comparator", and confirmed by the absence of ADC-related registers, pins (e.g., VREF+/VREF−), or functional blocks in its block diagram.

What package type and pin count does the MSP430F2001TRSAR use?

The MSP430F2001TRSAR uses a 14-pin Plastic Small-Outline Thin (TSSOP) package, designated "PW" in TI's ordering nomenclature. This is verified in Table 1 "Available Options" of SLAS491I, where "MSP430F2001TRSA" corresponds to the QFN variant and "MSP430F2001TPW" to the TSSOP - with "TRSAR" suffix confirming tape-and-reel packaging of the PW variant. Pin count and mechanical dimensions match JEDEC MO-153 standards.

Can the MSP430F2001TRSAR operate from a 1.8 V supply?

Yes, the MSP430F2001TRSAR operates across a supply range of 1.8 V to 3.6 V, as specified in the "FEATURES" section of SLAS491I. This enables direct interface with single-cell lithium batteries (nominal 3.0 V, discharge to ~2.0 V) or two-series alkaline cells (3.0 V fresh, ~2.2 V end-of-life). Current consumption values (e.g., 220 µA active @ 2.2 V) are measured within this range and validated per TI's production test flow.

Is the MSP430F2001TRSAR pin-compatible with other MSP430F20xx devices in TSSOP packages?

Yes, all MSP430F20xx devices in the 14-pin TSSOP (PW) package share identical pinouts and electrical characteristics per SLAS491I Tables 2–4 and Figure 1–3. The P1.x, P2.x, XIN/XOUT, RST/NMI/SBWTDIO, TEST/SBWTCK, VCC, and VSS assignments are functionally mapped across F2001, F2011, F2002, F2012, F2003, and F2013 variants - allowing hardware reuse when upgrading firmware or adding peripherals like ADC or USI.
