Texas Instruments MSP430G2001IPW14

Overview

MSP430G2001IPW14 from Texas Instruments is an ultralow-power 16-bit RISC microcontroller with 512 B flash, 128 B RAM, 10 I/O pins, a 16-bit Timer_A with two capture/compare registers, and support for 1.8 V to 3.6 V operation - used in battery-powered sensor nodes requiring sub-1 µs wake-up and <0.1 µA off-mode retention.

For engineers reviewing the MSP430G2001IPW14 datasheet, MSP430G2001IPW14 pinout, MSP430G2001IPW14 application, or MSP430G2001IPW14 equivalent, this page delivers verified functional identity, TSSOP-14 package mapping, confirmed low-power operating modes (LPM0–LPM4), validated I/O configuration, and real-world timing and power specifications directly traceable to TI SLAS695I.

Technical Context

The MSP430G2001IPW14 implements a 16-bit CPU with constant generators and seven addressing modes, executing register-to-register instructions in one MCLK cycle. Its clock system integrates a digitally controlled oscillator (DCO), internal low-frequency oscillator (VLO), and external crystal support (32 kHz) - enabling configurable ACLK, SMCLK, and MCLK domains.

It features a single 8-bit port P1 (8 I/O) and two-bit port P2 (2 I/O), each with individually programmable pullup/pulldown resistors, edge-selectable interrupts, and full read/write access via dedicated SFRs. The device lacks Comparator_A+ and flash information memory segments A–D calibration data - distinguishing it from G2x11 variants.

FAQ

What is the maximum operating frequency of the MSP430G2001IPW14?

The MSP430G2001IPW14 supports a maximum MCLK frequency of 16 MHz at VCC ≥ 3.3 V, 12 MHz at VCC = 2.7 V, and 6 MHz at VCC = 1.8 V. This is governed by the DCO calibration and voltage-dependent timing margins specified in SLAS695I Section 5.2. The MSP430G2001IPW14 achieves these frequencies without external crystals for core operation, though ACLK may use a 32.768 kHz crystal for real-time clock functions.

Does the MSP430G2001IPW14 include an analog comparator?

No, the MSP430G2001IPW14 does not include Comparator_A+. This is explicitly confirmed in Table 1 of SLAS695I, which lists "Comp_A+ Channel" as "–" for all MSP430G2001 variants. The comparator is present only in G2x11-family devices (e.g., MSP430G2111IPW14). The MSP430G2001IPW14 relies on external analog circuitry or software-based slope ADC techniques if analog threshold detection is required.

What debug interface does the MSP430G2001IPW14 support?

The MSP430G2001IPW14 supports Spy-Bi-Wire (SBW), a two-wire variant of JTAG implemented on pins RST/NMI/SBWTDIO (Pin 10) and TEST/SBWTCK (Pin 11). It does not support full 4-wire JTAG. This interface enables programming, erasure, and real-time debugging using TI's MSP-FET or compatible tools - confirmed in Section 1.1 and Figure 1 of SLAS695I. The MSP430G2001IPW14 requires no external voltage for programming.

How much flash memory is available on the MSP430G2001IPW14?

The MSP430G2001IPW14 contains 512 bytes of main flash memory, with no information memory (segments A–D) allocated. This is documented in Table 8 (Memory Organization) of SLAS695I, which shows "512B" under Flash for MSP430G2001. Unlike G2101/G2201 variants, the MSP430G2001IPW14 lacks factory-calibrated DCO settings in flash segment A, requiring user calibration if precise frequency accuracy is needed.

What are the key differences between MSP430G2001IPW14 and MSP430G2201IPW14?

The MSP430G2201IPW14 has 2 kB flash (vs. 512 B), retains the same 128 B RAM and 10 I/O pins, and adds a BSL bootloader and enhanced security fuse. Both share identical low-power modes, Timer_A2, clock system, and TSSOP-14 packaging. The MSP430G2001IPW14 targets minimal-footprint, fixed-function applications; the MSP430G2201IPW14 suits more complex firmware with field-update needs - confirmed in Table 1 of SLAS695I.
