MSP430F2011IN - 16MHz 16-Bit Ultra-Low-Power MCU | Texas Instruments
MPN： MSP430F2011IN ✓ 啟用中MSP430F2011IN 概覽
A microcontroller is a programmable system-on-chip containing a processor core, nonvolatile program memory, working memory, and peripherals that acquire or control external signals. The MSP430 family follows the hierarchy MCU → embedded microcontroller → mixed-signal microcontroller → semiconductor. Its 16-bit RISC architecture uses 16-bit registers and a constant-memory instruction set optimized for compact control firmware. Five low-power modes and fast standby wake-up make this device especially appropriate for portable, battery-powered measurement systems.
The MSP430F2011IN provides integrated timing and analog-comparison resources, including timer functions and a comparator, while its scan interface supports background capture of selected internal signals. The FLL+ frequency-locked loop and maximum 16 MHz operating frequency provide useful processing headroom for sensor acquisition, timing, state-machine control, and low-rate communication. Five power-saving modes allow firmware to reduce energy consumption when continuous CPU execution is unnecessary.
The device supports an ultra-low supply-voltage range of 1.8 V to 3.6 V. Its 16-bit RISC core executes instructions with a stated 125 ns instruction-cycle time at the maximum clock frequency. Active-mode current is specified as 220 µA at 1 MHz and 2.2 V, demonstrating that performance can be scaled by clock and operating-state requirements rather than operating continuously at the maximum frequency.
Typical uses include portable multimeters, environmental sensors, industrial measurement instruments, battery-powered data loggers, and compact embedded control products. The combination of 2 KB Flash, 128 bytes of SRAM, integrated comparator functions, and standby current of 0.5 µA suits designs that periodically wake, measure, process, and return to a low-power state.
Designers should verify startup behavior, pin multiplexing, and application-specific peripheral assignments against the manufacturer datasheet before final PCB release. Because the IN orderable uses a 14-pin through-hole package, breadboarding and hand assembly are straightforward, but its larger footprint is less compact than an equivalent surface-mount implementation.
This page combines verified manufacturer and distributor information, practical power-management guidance, package constraints, and same-family replacement context. It also separates published facts from data that still requires device-specific verification, helping engineers plan a qualified MSP430F2011IN design without relying on unverified equivalent parts.

典型應用
MSP430F2011IN 適用於 6 應用s: Portable Digital Multimeter, Battery-Powered Environmental Sensor, Industrial Data Logger, Low-Power Sensor Interface, Battery-Powered Control Module, Timing and Event-Counter Instrument.
Portable Digital Multimeter
The MSP430F2011IN suits a portable digital multimeter because its 16-bit RISC CPU can handle range selection, display updates, and measurement state control while its low-power modes reduce consumption between readings. The verified 220 µA active current at 1 MHz and 2.2 V provides a defined operating point, while standby current of 0.5 µA is useful when the instrument waits for user input. The integrated comparator and timer can support threshold detection and measurement timing. Firmware should select a lower clock when full performance is unnecessary and enter standby between samples to extend battery life.
Battery-Powered Environmental Sensor
The MSP430F2011IN can control a compact environmental sensor that periodically samples temperature, humidity, or gas-related analog signals. Its 1.8 V to 3.6 V supply range supports low-voltage sensor systems, while the comparator offers a low-power threshold or discrete-signal interface alongside timer-based sampling. Off-mode current of 0.1 µA with RAM retention and standby current of 0.5 µA help preserve operating state between measurements. The 128 bytes of SRAM is limited, so acquisition buffering and long records should be handled carefully rather than assuming the 2 KB Flash can serve as RAM.
Industrial Data Logger
For a low-rate industrial data logger, the MSP430F2011IN provides enough 16-bit processing capability to supervise sensors, timestamps events, and manage nonvolatile records. Its 2 KB Flash must be allocated carefully because it holds both firmware and logged data, while the 128-byte SRAM limits simultaneous sample buffering. The scan interface can support background observation of selected internal signals, and the timer can establish regular acquisition periods. A practical design should use interrupt-driven sampling, store compact records, and verify Flash endurance against the expected logging rate before committing to a specific storage strategy.
Low-Power Sensor Interface
The MSP430F2011IN is appropriate for a dedicated sensor interface that translates comparator or digital sensor events into a system output. Its 16-bit registers simplify handling of signed or scaled measurements, and the 16 MHz maximum clock provides margin for filtering and protocol tasks without requiring a larger processor in every measurement cycle. Operating current of 220 µA at 1 MHz and 2.2 V is the verified active-mode reference. Select a lower clock when latency permits, and use the device’s standby and off modes to avoid holding the sensor path active when no conversion is pending.
Battery-Powered Control Module
The MSP430F2011IN can serve as the control core in a small battery-powered module that operates actuators, indicators, or discrete loads through external circuitry. Its timer resources support deterministic scheduling, while the comparator and general-purpose I/O support simple threshold decisions and direct sensing. The microcontroller should remain in a low-power state whenever the controlled system is idle, using the verified 0.5 µA standby and 0.1 µA off-mode figures to estimate battery impact. Because the IN device is a 14-PDIP, it is particularly convenient for prototypes and through-hole industrial control assemblies where physical serviceability matters.
Timing and Event-Counter Instrument
The MSP430F2011IN is suited to timing-sensitive instrumentation that counts events, measures intervals, or sequences external conditions. Its 16-bit CPU and stated 125 ns instruction-cycle time support precise timing tasks, while timer functions reduce the amount of external logic required. The comparator can provide a direct threshold interface for a sensor or trigger source. For accurate measurements, the firmware should minimize interrupt latency, account for oscillator tolerance, and avoid entering a low-power mode during a timing window. The 14-PDIP package also simplifies temporary instrumentation and laboratory validation.

主要差異化特點
- Verified low-power operating points (對比MSP430F2012IPM)
- Serviceable through-hole package (對比MSP430F2011TN)
- Compact memory and mixed-signal integration (對比MSP430F2001IPM)
設計說明
Use the published operating points as design anchors: active 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. Select the clock, peripherals, and duty cycle to match the application instead of leaving the device at its maximum frequency. Estimated battery impact should be calculated from the measured average current rather than from active-mode current alone.
The MSP430F2011IN uses a 14-PDIP footprint, which simplifies prototype insertion and through-hole assembly but occupies more board area than a surface-mount variant. Place the decoupling capacitor and any required VCAP or oscillator components according to the manufacturer layout guidance. Preserve access to all I/O pins and confirm that the chosen socket or PCB pattern does not interfere with adjacent tall components.
Do not treat MSP430F2011TN and MSP430F2011IN as interchangeable footprints, and do not assume every MSP430F2xx member has identical pin multiplexing, memory, or peripheral resources. Before substituting a same-family part, compare the complete manufacturer pin table, Flash size, SRAM capacity, timer channels, comparator inputs, clock requirements, and supply limits. The verified cross-reference result supports family similarity but does not establish complete drop-in equivalence.
For analog comparator or sensor measurements, use the manufacturer’s recommended analog and digital layout practices even though the package is through-hole. Keep analog inputs away from switching nodes and high-current return paths, provide a stable local supply path, and evaluate whether long DIP leads add capacitance or susceptibility. If timing accuracy is critical, characterize the complete assembled circuit rather than relying only on the nominal instruction-cycle time.
