Texas Instruments MSP430F2001TRSAT

Overview

MSP430F2001TRSAT 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 from standby mode.

For engineers reviewing the MSP430F2001TRSAT datasheet, MSP430F2001TRSAT pinout, MSP430F2001TRSAT application, or MSP430F2001TRSAT equivalent, key selection criteria include its 1.8–3.6 V supply range, 0.1 µA off-mode current with RAM retention, TSSOP-14 package footprint, and absence of ADC or USI peripherals - distinguishing it from MSP430F20x2/x3 variants.

Technical Context

The MSP430F2001TRSAT implements a 16-bit CPU with seven addressing modes and register-to-register execution in one MCLK cycle. 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 <1 µs active-mode wake-up from LPM4.

It features a single 8-bit I/O port (P1) with individually configurable pullup/pulldown resistors and edge-selectable interrupts on all eight pins, plus two P2 I/O bits (XIN/XOUT). The integrated Comparator_A+ supports eight-channel analog input multiplexing and rail-to-rail operation, but lacks sigma-delta or SAR ADC functionality present in F20x2/F20x3 family members.

FAQ

What is the maximum operating frequency of the MSP430F2001TRSAT?

The MSP430F2001TRSAT supports a digitally controlled oscillator (DCO) with factory-calibrated frequencies up to 16 MHz ±1%, enabling instruction execution at 16 million cycles per second. This maximum frequency is achievable across the full 1.8–3.6 V supply range and -40°C to +105°C temperature range, as verified in TI's SLAS491I datasheet revision December 2012.

Does the MSP430F2001TRSAT include an analog-to-digital converter (ADC)?

No, the MSP430F2001TRSAT does not include an ADC. It belongs to the MSP430F20x1 subfamily, which integrates only the Comparator_A+ module - not the 10-bit ADC10 (found in F20x2) or 16-bit SD16_A (found in F20x3). Analog signal digitization requires external ADC or comparator-based slope-A/D techniques using Timer_A.

What debug interface does the MSP430F2001TRSAT support?

The MSP430F2001TRSAT supports Spy-Bi-Wire (SBW), a two-wire variant of JTAG implemented via RST/NMI/SBWTDIO and TEST/SBWTCK pins. This interface enables full in-system programming, breakpoint debugging, and memory inspection using TI's MSP-FET or compatible tools - eliminating the need for a 4-pin JTAG header.

Is the MSP430F2001TRSAT pin-compatible with other MSP430F20xx devices in TSSOP-14?

Yes, the MSP430F2001TRSAT shares identical pinout and electrical characteristics with MSP430F2011TRSAT, MSP430F2002TRSAT, and MSP430F2012TRSAT in the TSSOP-14 (PW) package. All F20xx TSSOP-14 variants use the same terminal functions and I/O mapping, enabling hardware reuse across memory and peripheral variants.

What is the purpose of the CAOUT pin on the MSP430F2001TRSAT?

The CAOUT pin (P1.3 and P1.7) provides the direct output of the integrated Comparator_A+. It asserts logic-high when the positive input exceeds the negative input, enabling zero-crossing detection, window-compare logic, or wake-up triggering without CPU involvement - reducing active-mode time and power consumption.
