MSP430F2001IN - 16MHz MCU, 1KB Flash | Texas Instruments
部品番号: MSP430F2001IN ✓ 生産中MSP430F2001IN 概要
A microcontroller is a programmable integrated circuit containing a processor core, nonvolatile program memory, working RAM, and peripherals. The MSP430F2001 belongs to the MSP430 MCU family, whose RISC architecture is designed for low-power embedded control. Within the hierarchy of embedded semiconductors, the MSP430F2001IN is a microcontroller, mixed-signal processor, embedded processor, and system-on-chip device with timer and comparator functions.
The most prominent specifications visible in the verified product information are its 16 MHz operating frequency, 1 KB Flash, 128 B SRAM, and 14-pin PDIP package. Its 16-bit RISC architecture supports efficient execution of compact control routines, while the on-chip timer supports periodic event generation and timing tasks. The integrated comparator allows threshold-based input decisions without requiring a separate comparator IC. Five power-saving modes, standby wake-up in less than 6 microseconds, and a 125 ns instruction-cycle time were also identified in the retrieved technical material.
The limited 1 KB Flash and 128 B SRAM distinguish this device from larger MSP430 products. Firmware must therefore be compact, while RAM variables and interrupt-service routines require careful memory budgeting. This constraint is not a drawback for simple sensing and control nodes, but it makes the MSP430F2001IN less suitable for protocol-heavy gateways, graphical interfaces, large protocol stacks, or applications requiring extensive data buffering.
Typical uses include battery-operated sensors, simple industrial measurement nodes, compact control panels, timer-based equipment, and low-power embedded systems. Designers can place the MCU between physical inputs and an actuator or communications interface, using the comparator for threshold detection and the timer for periodic measurement or control. Its small memory footprint can simplify firmware verification and make behavior easier to analyze than in a larger embedded platform.
The principal design consideration is to confirm the complete operating voltage range, current consumption, peripheral assignment, and exact pin mapping in the manufacturer datasheet before layout or firmware release. The verified material confirms the 14-pin PDIP package but does not provide a complete pin table, so pin assignments should not be inferred from the package count. This page consolidates verified product facts, sourcing information, drop-in candidates, and practical selection guidance beyond a distributor listing.
For new production designs, engineers should also evaluate MSP430 devices with more Flash or SRAM when future firmware growth is likely. For cost-sensitive, low-complexity products that fit within 1 KB Flash and 128 B SRAM, the MSP430F2001IN remains a compact mixed-signal MCU option with a documented 16 MHz clock and integrated timer and comparator resources.

主な用途
MSP430F2001IN の用途: 6 件s: Battery-Powered Sensor Node, Industrial Threshold Monitor, Timer-Based Control Module, Low-Power Data Logger, Simple Portable Instrument, Compact Control Panel.
Battery-Powered Sensor Node
MSP430F2001IN fits a compact sensor node because it combines a 16 MHz processor, 128 B SRAM, five power-saving modes, and standby wake-up in less than 6 microseconds. The timer can schedule periodic sampling while the comparator can perform a local threshold decision before data is transmitted. Its reported 0.1 uA off-mode current with RAM retention is useful for duty-cycled designs, although the final battery budget must use the manufacturer operating-current table. The 1 KB Flash limit favors short, event-driven firmware, and the 14-pin PDIP package simplifies through-hole prototypes and repairable low-volume assemblies.
おすすめ
Industrial Threshold Monitor
The integrated comparator makes MSP430F2001IN useful for a small industrial threshold monitor that evaluates a sensor or divided reference voltage. The 16 MHz clock and 125 ns instruction-cycle time allow the firmware to respond quickly, while the timer supports periodic sampling and alarm timing. Because only 128 B SRAM is available, the implementation should store summarized values rather than long data histories and should avoid large buffering arrays. The 14-pin PDIP package is practical for panel-mounted prototypes, while industrial production requirements should be checked against the verified operating-temperature and compliance information.
おすすめ
Timer-Based Control Module
MSP430F2001IN can implement a compact timer-based controller for pumps, indicators, heaters, or repetitive sequencing where the required logic fits within 1 KB Flash. Its on-chip timer reduces the need for a separate timing IC, and the 16 MHz CPU provides a short 125 ns instruction cycle for deterministic polling. The principal engineering trade-off is memory capacity: scheduling tables, communications handlers, and safety routines can consume the limited Flash quickly. Firmware should therefore use compact state representations, and the final design must verify timer resources, I/O assignments, and supply limits in the manufacturer documentation.
おすすめ
Low-Power Data Logger
MSP430F2001IN can serve as the control element in a very small data logger that wakes from a low-power state, samples an input, applies a threshold or scaling operation, and returns to sleep. Its five power-saving modes and less-than-6-microsecond standby wake-up suit event-driven acquisition, while the comparator can reduce the amount of processing required for simple crossings. The 128 B SRAM limits buffering depth, and the 1 KB Flash leaves little room for a complex file system or protocol stack. This approach works best when samples are summarized locally and retained data is transferred in small, bounded blocks.
おすすめ
Simple Portable Instrument
The MSP430F2001IN is suitable for a simple portable measurement instrument that combines a sensor input, a threshold decision, and a basic user indication. The 16 MHz maximum clock supports responsive control without demanding a high-performance processor, and the integrated timer can organize measurement intervals. Its 14-pin PDIP format is useful for a compact prototype or repairable instrument assembly, although a surface-mount option would normally be preferred for a high-volume portable product. With only 1 KB Flash and 128 B SRAM, the display routine, calibration data, and measurement code must be kept deliberately small.
おすすめ
Compact Control Panel
MSP430F2001IN can support a compact control panel with periodic button polling, indicator control, and one or more threshold inputs. Its integrated timer provides a scheduling resource, while the comparator handles simple level decisions without requiring another dedicated IC. The device is most appropriate when the panel contains only a few functions and the firmware does not require extensive graphics, logging, or communications. The through-hole 14-pin PDIP package makes hand assembly and prototype rework straightforward. Before release, engineers should confirm the available GPIO, timer channels, reset behavior, and exact operating limits against the manufacturer datasheet.

設計ノート
Estimate the average current from the actual duty cycle rather than from the 0.1 uA off-mode figure alone. The MSP430F2001IN can remain in a low-power state between events, but sensor conversion, comparator operation, timer wake-ups, and brief 16 MHz execution periods contribute to the average load. Use the manufacturer operating-current table at the selected supply voltage and clock frequency, then add measured peripheral current before sizing the battery.
Reserve the standard 14-pin PDIP footprint and follow the exact pin numbers and pin-1 orientation shown in the manufacturer package drawing. The verified data confirms the package and pin count but does not provide individual pin functions, so the schematic and PCB must be cross-checked against the official MSP430F2001 documentation. Do not infer I/O, reset, clock, or power assignments from neighboring pins or from another MSP430 variant.
Treat the 1 KB Flash and 128 B SRAM as hard design boundaries. Reserve space for interrupt vectors, constants, stack depth, and prospective bootloader functions, and avoid allocating large buffers. If the application later adds communications, calibration tables, logging, or richer user-interface behavior, move to a higher-memory MSP430 before PCB release rather than assuming the existing firmware can be expanded.
Keep the MSP430F2001IN supply bypass path short and follow the manufacturer's recommended input and output capacitor configuration once confirmed from the datasheet. For a mixed-signal design, route comparator-sensitive and timer-sensitive signals away from switching nodes and high-current actuator wiring. Because this is a through-hole PDIP package, also inspect lead spacing, soldering accessibility, and prototype rework requirements during layout review.
