Product details

Overview

MSP430F2011TN from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 2KB+256B flash 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 is used in battery-powered sensor nodes requiring analog signal acquisition, timing control, and minimal energy consumption.

For engineers reviewing the MSP430F2011TN datasheet, MSP430F2011TN pinout, MSP430F2011TN application, or MSP430F2011TN equivalent, key selection criteria include its 14-pin TSSOP (PW) or PDIP (N) package, integrated comparator (MSP430F20x1 family), absence of ADC or USI peripherals, and compatibility with Spy-Bi-Wire on-chip emulation.

Technical Context

The MSP430F2011TN implements a 16-bit RISC CPU with 62.5-ns instruction cycle time and constant generators for optimized code efficiency. Its basic clock module delivers internal DCO frequencies up to 16 MHz with four factory-calibrated points (±1%), plus support for 32-kHz crystal or external digital clock sources.

It belongs to the MSP430F20x1 variant group and includes an on-chip analog comparator with eight-channel input multiplexer and CAOUT output, but excludes ADC10 (F20x2) and SD16_A (F20x3). The device uses a single 8-bit I/O port (P1) and two P2 pins, all with individually programmable pullup/pulldown resistors and edge-selectable interrupts.

FAQ

What is the maximum operating frequency of the MSP430F2011TN?

The MSP430F2011TN supports a digitally controlled oscillator (DCO) with four factory-calibrated frequencies up to 16 MHz (±1%). While the core executes instructions at 62.5-ns cycle time, sustained operation at 16 MHz requires proper decoupling and thermal management within the -40°C to 105°C rating. The device does not require an external crystal to achieve this speed.

Does the MSP430F2011TN include an analog-to-digital converter (ADC)?

No, the MSP430F2011TN does not include an ADC. It belongs to the MSP430F20x1 family, which features only the on-chip analog comparator (with eight inputs and CAOUT output). ADC functionality is present in the MSP430F20x2 (10-bit ADC10) and MSP430F20x3 (16-bit SD16_A) variants, but not in the MSP430F2011TN.

Which package options are available for the MSP430F2011TN?

The MSP430F2011TN is offered exclusively in the 14-pin plastic dual-inline package (PDIP-N), rated for -40°C to 105°C operation. Unlike the PW (TSSOP) and RSA (QFN) variants, the 'TN' suffix denotes the PDIP package with through-hole mounting - suitable for prototyping, legacy board designs, and high-reliability industrial assemblies.

How is debugging and programming performed on the MSP430F2011TN?

Debugging and programming of the MSP430F2011TN use the Spy-Bi-Wire interface, a two-wire variant of JTAG implemented on pins RST/NMI/SBWTDIO and TEST/SBWTCK. This eliminates the need for a full 4-wire JTAG header, reduces PCB space, and supports in-system programming without removing the device from the board.

What distinguishes the MSP430F2011TN from the MSP430F2013TN?

The MSP430F2011TN (F20x1) includes only the analog comparator, whereas the MSP430F2013TN (F20x3) integrates a 16-bit sigma-delta ADC (SD16_A) with differential PGA inputs and internal reference. Both share 2KB flash and 128B RAM, but the MSP430F2013TN consumes higher active current and targets high-precision sensor measurement, while the MSP430F2011TN prioritizes lowest possible power and comparator-based decision logic.
