MSP430F2001TN - 16MHz Ultra-Low-Power MCU | Texas Instruments
部品番号: MSP430F2001TN ✓ 生産中MSP430F2001TN 概要
A mixed-signal microcontroller is an embedded semiconductor that combines digital processing with analog functions. The MSP430 architecture belongs to the broader hierarchy of microcontrollers, embedded processors, and semiconductors. Its 16-bit RISC core uses a 125 ns instruction cycle, while the digitally controlled oscillator and FLL+ support flexible clock generation for energy-efficient operation.
Low power is a defining feature of the MSP430F2001 family. Its supply-voltage range is 1.8 V to 3.6 V, active-mode current is 220 µA at 1 MHz and 2.2 V, standby current is 0.5 µA, and off-mode current with RAM retention is 0.1 µA. Five power-saving modes help reduce energy consumption when the application does not require continuous processing.
The device provides a 16 MHz clock capability, a built-in 16-bit timer, ten I/O pins, and a versatile analog comparator. The comparator can support threshold detection and basic signal conditioning, while the timer supports periodic timing, counting, and event generation. The digitally controlled oscillator permits wake-up from low-power modes to active mode in less than 1 µs.
Typical uses include battery-powered sensor nodes, compact industrial monitors, low-energy measurement instruments, appliance control modules, and embedded systems that periodically sample a sensor and return to a low-power state. Its small package and low active current are particularly useful where board space and average energy use are more important than maximum processing throughput.
When designing around the MSP430F2001TN, account for the limited 1 KB flash and 128 B SRAM when sizing code, buffers, and state variables. Keep interrupt routines short, use a low-power operating mode during idle intervals, and verify comparator and timer behavior across the intended supply-voltage range. The manufacturer pin-description table should be used when assigning PCB signals and programming test points.
This page combines the exact manufacturer and distributor product information with application guidance, power-mode considerations, and design notes that help engineers evaluate the MSP430F2001TN beyond a basic parameter list.

主な用途
MSP430F2001TN の用途: 6 件s: Battery-Powered Sensor Nodes, Compact Industrial Monitoring, Battery-Powered Measurement Instruments, Appliance Control Modules, Threshold Detection and Alarm Systems, Educational and Embedded Prototyping.
Battery-Powered Sensor Nodes
The MSP430F2001TN fits periodic sensor nodes because its 1.8 V to 3.6 V operating range and 0.5 µA standby current reduce the energy burden between measurements. The 16 MHz CPU can execute sampling and filtering tasks, while the 125 ns instruction cycle supports responsive control logic. Its 0.1 µA off-mode current with RAM retention also helps preserve state during long inactive periods. A typical design powers the analog sensor from the same low-voltage rail, samples at a controlled interval, and returns the MCU to standby to limit average consumption.
おすすめ
Compact Industrial Monitoring
The MSP430F2001TN is suitable for compact industrial monitors that combine a threshold signal with a timer-based sampling interval. Its integrated analog comparator can detect a sensor or control signal crossing a reference level without requiring a separate comparator IC. The built-in 16-bit timer supports periodic readings, debounce intervals, and timeout functions, while ten I/O pins can connect digital sensors, indicators, or a communications module. The low-power modes are valuable in remote installations where equipment operates intermittently.
おすすめ
Battery-Powered Measurement Instruments
The MSP430F2001TN supports handheld and portable measurement equipment where current consumption influences battery life. Its 220 µA active current at 1 MHz and 2.2 V provides a practical baseline for workloads that alternate between measurement and standby. The comparator handles simple threshold crossings, and the 16-bit timer can organize acquisition intervals or timeout behavior. With only 128 B of SRAM and 1 KB of flash, however, the design should stream complex data or use external storage rather than buffer large datasets locally.
おすすめ
Appliance Control Modules
The MSP430F2001TN can serve as the central controller in a small appliance module that operates buttons, indicators, a timing element, and a simple analog feedback path. Ten I/O pins provide enough connectivity for discrete controls, while the 16-bit timer supports delayed actions and repetitive sequences. The analog comparator can monitor a threshold derived from a potentiometer or another slow-moving signal. Its small PDIP package and low-voltage operation also simplify through-hole prototypes and low-power production boards.
おすすめ
Threshold Detection and Alarm Systems
The MSP430F2001TN is useful in threshold-detection products because its integrated analog comparator can supervise an analog input while the CPU handles acknowledgement, logging, or output control. The fast transition from low-power mode to active mode, stated as less than 1 µs, allows the system to react promptly to an interrupt-driven event. The timer can add retrigger delays or debounce behavior. Designers should verify comparator operating limits and output behavior across the full 1.8 V to 3.6 V supply range before finalizing the analog network.
おすすめ
Educational and Embedded Prototyping
The MSP430F2001TN works well in educational and embedded prototyping projects because it combines a 16-bit RISC core, timer, comparator, ten I/O pins, and accessible low-power modes in a 14-pin PDIP package. Through-hole construction makes it straightforward to mount on a solderless board or a perforated prototype board. Learners can use the timer for scheduling, the comparator for analog threshold experiments, and the GPIO ports for switches and indicators. Firmware development must remain within the 1 KB flash and 128 B SRAM limits while the design concept is being evaluated.

選定ガイド
Do not select it merely because another MSP430 has a similar CPU. A valid substitute must match the package, pin functions, supply range, and required peripherals, and its memory capacity must fit the firmware. The MSP430F135IPM may suit a larger or more connected embedded design, but it is not a pin-compatible replacement for the MSP430F2001TN. Likewise, a different package suffix in the same device family may require a different PCB footprint and pin assignment. Confirm programming, memory-map, timing, and peripheral requirements before approving any alternate device.

主な差別化要因
- Fast low-power response （vs General-purpose 16-bit MCUs without a comparably documented sub-microsecond wake-up)
- Integrated mixed-signal resources （vs A digital-only MCU requiring an external comparator)
- Low standby and off-mode consumption （vs A continuously active MCU)
設計ノート
Estimated: With a 3.0 V supply, 2.2 V output, and 10 mA average load, the ideal linear-regulator loss is 0.008 W using (3.0 V - 2.2 V) × 0.010 A. Actual consumption also includes the MCU active current, sensor load, regulator quiescent current, and leakage. Select the supply and regulator so the average current, peak load, and standby leakage remain inside the power budget; the specified 220 µA active current applies at 1 MHz and 2.2 V.
Do not size firmware and RAM as though this were a larger MSP430 model. The device has 1 KB of flash and 128 B of SRAM, so large lookup tables, buffering, libraries, or recursive routines can exhaust memory. Keep interrupt handlers short, measure stack depth, and place larger data sets in external memory if the application cannot be simplified. Confirm linker output and reserve sufficient stack space for interrupts and nested call chains.
Use the manufacturer pin-description table to assign the 14 PDIP connections and preserve the exposed supply and ground paths. Place decoupling capacitance close to the device supply pins with a short, low-inductance return to ground. Keep sensitive comparator inputs away from switching-node copper and high-current return paths. Because the through-hole package has generous lead spacing, lead length should still be minimized where signal timing or noise sensitivity is important.
Treat standby and active current as separate design targets. The device is specified at 0.5 µA in standby, 0.1 µA in off mode with RAM retention, and 220 µA in active mode at 1 MHz and 2.2 V. If the MCU wakes frequently, the active-mode duration and wake-up frequency may dominate average consumption. Measure the complete board, including pull resistors, sensors, indicators, and regulator losses, rather than relying only on the MCU current specification.
