MSP430F2011TN - 16MHz 16-Bit MCU | Texas Instruments | Embedded
N.º de pieza: MSP430F2011TN ✓ ActivoMSP430F2011TN Descripción general
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. In the MSP430 family, the 16-bit RISC core is optimized for low-power embedded control, while integrated timers and comparators reduce the need for external components. The MSP430F2011TN therefore sits within the hierarchy of microcontroller, embedded processor, mixed-signal MCU, and semiconductor.
The primary verified specifications are a 16 MHz operating frequency, 2 KB of Flash, and 128 bytes of SRAM. The device also includes a timer and comparator, according to the Texas Instruments product page. Its 14-pin PDIP package is intended for conventional through-hole PCB assembly, prototyping, and legacy or industrial control designs where a leaded package simplifies inspection and manual servicing.
The MSP430F2011TN uses a 16-bit CPU architecture and combines digital control with analog comparison functions. Although the verified distributor snippet also describes a 2K × 8 organization plus 256 bytes of Flash, the official product summary identifies 2 KB of Flash and 128 bytes of SRAM; engineers should therefore confirm the exact memory map in the manufacturer datasheet before allocating program or data space.
Typical uses include low-power sensor nodes, simple control panels, battery-operated instruments, comparator-based threshold circuits, and compact industrial controllers. The comparator can monitor an analog input locally, while the timer supports periodic measurement, timing, or control functions. The 14-pin package is especially suitable where a small through-hole controller is preferred over a fine-pitch surface-mount device.
When designing around this MCU, verify the oscillator, reset, I/O, comparator-input, and supply-pin assignments against the exact package drawing before laying out the PCB. Program and data budgets must also be checked because only 2 KB of Flash and 128 bytes of SRAM are available in the verified product summary. Decoupling, reset behavior, and unused-pin handling should follow the manufacturer’s hardware guidelines.
This page consolidates verified manufacturer and distributor information, orderable MPN details, price context, drop-in alternatives, and practical selection guidance. It is designed to help engineers identify whether the MSP430F2011TN is suitable for a new embedded design or as a controlled replacement within the 14-pin PDIP MSP430F2011 family.

Aplicaciones típicas
MSP430F2011TN es adecuado para 6 aplicacións: Battery-Powered Sensor Node, Comparator-Based Threshold Control, Industrial Timer and Sequence Controller, UART-Based Configuration Interface, Portable Measurement Instrument, RS-232 and CAN Network Endpoint.
Battery-Powered Sensor Node
The MSP430F2011TN fits compact, battery-operated sensor nodes that require local control, periodic sampling, and low standby activity. Its verified 16 MHz 16-bit CPU provides straightforward execution for sensor conditioning logic, while 128 bytes of SRAM and 2 KB of Flash support small firmware routines rather than buffered data analysis. The timer can establish sampling intervals, and the integrated comparator can implement a simple threshold event without a separate comparator IC. Because the verified sources do not provide operating-current figures for this exact MPN, battery sizing must use the manufacturer’s electrical characteristics. A low-quiescent-current regulator and controlled use of peripheral clocks should be included in the power budget.
Recomendado
Comparator-Based Threshold Control
The MSP430F2011TN is appropriate when an analog signal must be compared against a threshold before a digital control action is taken. Its integrated comparator avoids allocating a separate comparator package and board area, while the 16-bit CPU can debounce the result, update a counter, and drive an output. The verified 16 MHz operating frequency is substantially faster than the immediate threshold decision itself, leaving execution time for application logic and serial reporting. Exact comparator input selection, reference method, and response timing must be confirmed in the manufacturer datasheet because those details were not included in the supplied snippets. Firmware should also account for input noise and switching transients when defining a practical threshold margin.
Recomendado
Industrial Timer and Sequence Controller
The MSP430F2011TN can implement a compact industrial timer, duty-cycle sequencer, or simple process controller when it must operate directly from a through-hole assembly. The verified timer peripheral supports periodic timing, while the 16-bit CPU executes the state machine and the comparator provides an additional local threshold input. Its 14-pin PDIP package is mechanically convenient for boards where components are assembled by insertion rather than fine-pitch reflow. Firmware should be kept within the verified 2 KB Flash and 128-byte SRAM limits, or a higher-memory family member should be considered. Industrial qualification, supply voltage limits, and operating-temperature requirements are not specified in the supplied data and must be checked before deployment.
Recomendado
UART-Based Configuration Interface
The MSP430F2011TN can serve as the low-power controller behind a simple UART configuration port used for field updates, diagnostics, or production programming. Its 16-bit CPU is sufficient for protocol handling and command parsing, while 2 KB of Flash favors concise firmware and 128 bytes of SRAM requires careful buffering. A bridge such as the CP2102N family can translate USB to a serial interface during development or commissioning. Because the verified data does not specify the MCU’s UART peripheral details, pin assignment, baud-rate support, or electrical levels, engineers must consult the exact manufacturer datasheet before selecting pull-ups, connector protection, or level-shifting components.
Recomendado
Portable Measurement Instrument
The MSP430F2011TN fits portable measurement instruments where a small mixed-signal controller can combine timing, threshold detection, and local control. The comparator can monitor a slowly changing analog quantity, while the timer establishes a measurement or calibration interval and the MCU records status through a serial interface. Its compact 14-pin PDIP package is useful in handheld or laboratory modules where through-hole assembly is acceptable. The verified memory limits are tight for trace storage, so the device is best suited to streaming or summarized measurements rather than large data logs. A precision reference, analog front end, and regulator must be selected separately, and the final accuracy budget should include comparator offset, noise, and temperature effects from the manufacturer data.
Recomendado
RS-232 and CAN Network Endpoint
The MSP430F2011TN can be used as a compact protocol-conversion or status endpoint when the board must combine local timing and analog monitoring with an external communications interface. The 16 MHz MSP430 core can supervise the serial transceiver while the timer maintains periodic update intervals and the comparator provides a digital event source. MAX232DR is a relevant RS-232 level-interface option, and TCAN334DR is a relevant CAN interface option for designs requiring that network type. These devices are interface companions rather than drop-in MCU substitutes. Firmware, interrupt allocation, and buffer sizing must remain within the verified 128 bytes of SRAM, while the 2 KB Flash limit favors a compact communication state machine and selective feature support.

Notas de diseño
Estimate the average and peak supply current before fixing the power architecture because the supplied sources do not include operating-current values for MSP430F2011TN. Multiply active-state current by the measured MCU duty cycle, add comparator, timer, oscillator, and interface loads, and compare the result with regulator capacity. Keep the regulator, decoupling network, and any communication interface on the same ground reference. The manufacturer datasheet should provide the exact supply range and current limits required for a production design.
Obtain the official N-package drawing before assigning the 14 leads. Place the MCU near the oscillator components when an external crystal or resonator is used, and route oscillator traces away from switching nodes and communication lines. Follow the manufacturer’s recommended supply and ground layout, with short paths and local decoupling. Because the exact pin map was not included in the verified search data, a provisional board layout should not be released until the official 14-pin diagram has been cross-checked.
The most important firmware risk is exceeding the verified 2 KB Flash and 128-byte SRAM limits. Include compiler overhead, interrupt vectors, constants, stack depth, and communication buffers in the memory budget rather than counting only application source code. Remove unused library features, avoid large frame buffers, and test worst-case interrupt nesting. The DigiKey Flash description differs from the official summary, so the device memory map should also be checked before assigning addresses or relying on reserved regions.
Do not treat every 14-pin PDIP MSP430 as an unconditional substitute. Confirm power pins, reset behavior, oscillator connections, I/O assignments, comparator channels, timer resources, voltage limits, and temperature grade against the manufacturer’s ordering table and datasheet. In particular, MSP430F2011IN is web-verified, while the other listed family alternatives come from model knowledge and require direct TI documentation review before schematic or firmware release.
