부품 번호: MSP430F110IDW ✓ 활성MSP430F110IDW 개요
A mixed-signal microcontroller combines a digital microprocessor core with analog and timing peripherals on one integrated device. The MSP430 belongs to the broader hierarchy of embedded processor, microcontroller, and semiconductor categories. Its 16-bit RISC architecture supports efficient instruction execution, while the integrated clock, memory, and mixed-signal peripherals reduce the number of discrete components required in a measurement or control design.
Key characteristics include an 8 MHz clock capability, a 125 ns instruction-cycle time, 1 KB of flash memory organized as 1K x 8 plus 128 bytes of RAM, and a 3.6 V maximum low-supply voltage. The device also supports standby and low-power off operation, including a stated 0.1 µA off current with RAM retention. These characteristics make it useful for low-duty-cycle sensing, control, metering, and embedded measurement systems.
The MSP430 architecture emphasizes efficient mixed-signal system design through its basic clock module, 16-bit RISC processing, and integrated low-power operating modes. Its 128-byte RAM supports stack, variables, and short working data sets, while flash provides nonvolatile program storage. At an 8 MHz maximum clock, the stated 125 ns instruction-cycle time corresponds to a fast instruction execution rate, allowing the core to service timing-sensitive peripheral operations without an external processor.
Typical applications include low-power sensor nodes, compact industrial measurement instruments, battery-operated monitoring equipment, digital meters, and embedded control modules. The MSP430F110IDW can also serve as the central controller in designs where compact package size, low standby demand, and integrated analog measurement functions matter more than large memory capacity or extensive connectivity.
Designers should verify the exact pin assignment and peripheral multiplexing in the Texas Instruments MSP430F110 datasheet before laying out a PCB. Because the device provides only 1 KB of flash and 128 bytes of RAM, firmware must remain compact, interrupt service routines should be efficient, and application code must avoid unnecessary buffering. The 20-pin SOIC footprint simplifies assembly but requires careful assignment of communication, analog, clock, and debug functions among the available pins.
This product page combines the exact MSP430F110IDW device identity, package and memory details, verified pricing channels, replacement assessment, and practical design guidance. It also highlights where similarly named MSP430 devices share the 20-pin SOIC footprint and where their available functions and memory resources must be checked before a replacement is approved.

일반적인 애플리케이션
MSP430F110IDW 적합 용도: 6 애플리케이션s: Low-Power Sensor Node, Compact Digital Meter, Industrial Control Module, Battery-Operated Monitoring Equipment, Timing-Critical Control Module, Embedded Data-Acquisition Front End.
Low-Power Sensor Node
The MSP430F110IDW fits intermittent sensor nodes that wake, acquire a measurement, process it briefly, and return to standby. Its 16-bit RISC core operates up to 8 MHz, while the 1 KB flash and 128 bytes of RAM support compact firmware and small working buffers. The stated 0.1 µA off current with RAM retention helps preserve operating state between measurements. A practical design should disable unused peripherals, minimize active-time energy, and use the Texas Instruments MSP430F110 datasheet to configure wake-up timing and port states.
추천
Compact Digital Meter
The MSP430F110IDW is appropriate for a compact digital meter in which deterministic timing, low power, and local signal processing are more important than large application memory. Its 16-bit RISC architecture, 8 MHz maximum clock, and 125 ns instruction-cycle time support responsive display updates and input handling, while 1 KB of flash constrains the program to a focused measurement routine. The 3.6 V maximum supply voltage also simplifies integration with compact low-voltage systems. Use the manufacturer pin-description table to assign display, switch, and measurement interfaces without conflicting multiplexed functions.
추천
Industrial Control Module
The MSP430F110IDW can serve as the local controller in a small industrial control module that coordinates discrete inputs, timers, and simple actuators. Its 16-bit RISC core and 8 MHz clock provide responsive handling of control logic, while the 20-pin SOIC package remains compatible with conventional board assembly methods. The 1 KB flash and 128 bytes of RAM require a structured firmware architecture with limited buffering and short interrupt handlers. System-level qualification should cover temperature range, isolation, surge immunity, and electromagnetic compatibility because the component itself is a general-purpose mixed-signal controller.
추천
Battery-Operated Monitoring Equipment
The MSP430F110IDW suits battery-operated monitoring equipment that spends most of its operating time between short active intervals. Its low-power modes, 3.6 V maximum supply voltage, and stated 0.1 µA off current with RAM retention support energy-conscious operation, while the 16-bit RISC core provides enough arithmetic capability for basic filtering and threshold decisions. The limited 128 bytes of RAM favors streaming or single-sample processing rather than long records. Firmware should use the clock and low-power modules according to the Texas Instruments MSP430F110 datasheet to avoid unnecessary wake-ups and active-state overhead.
추천
Timing-Critical Control Module
The MSP430F110IDW is useful in a timing-critical embedded control module where predictable instruction execution and compact code size matter. Its 16-bit RISC core supports an 8 MHz maximum clock and a stated 125 ns instruction-cycle time, enabling efficient timer, counter, and discrete control tasks without an external processor. The device is particularly suitable when the required memory footprint is no more than 1 KB of flash and 128 bytes of RAM. Validate every timer input, interrupt vector, and output-pin multiplexing against the manufacturer datasheet, and keep interrupt routines short to preserve deterministic response.
추천
Embedded Data-Acquisition Front End
The MSP430F110IDW can act as the supervisory controller in a small mixed-signal data-acquisition front end. Its basic clock module and mixed-signal architecture allow digital control functions to coexist with an external analog conversion path, while the 8 MHz 16-bit core can handle sampling sequencing and threshold logic. The 128-byte RAM is suitable for short acquisition bursts but not large histories, so results should be transferred or summarized promptly. The 3.6 V maximum supply voltage supports low-voltage analog interfaces, although calibration, input bandwidth, reference accuracy, and channel isolation must be addressed at the circuit level.

설계 노트
Design the 3.6 V maximum supply rail with transient margin for the MSP430F110IDW and all attached peripherals. Place the regulator output capacitor and local bypass capacitor close to the device's supply and ground pins, and keep analog and digital return currents separated as far as the board area permits. Use the manufacturer power-pin connection diagram to identify every supply connection and avoid leaving an undocumented pad or test point to float.
Assign the 20 available pins from the MSP430F110 datasheet pin-description table before finalizing the schematic. Several MCU functions can be multiplexed onto the same pin, so changing an analog input to a digital output can affect neighboring circuitry. Preserve the recommended ground and decoupling layout, keep clock-related routing compact, and do not route high-current or high-voltage switching paths beneath sensitive analog inputs.
Avoid treating similar MSP430F110-family order codes as automatically interchangeable. The target has 1 KB of flash and 128 bytes of RAM, so firmware that links against another family member may exceed code or data space even when the package is identical. During substitution, compare linker-map requirements, interrupt vectors, timer assignments, port multiplexing, voltage limits, and temperature grade rather than checking only the package drawing.
Use the low-power modes only after accounting for leakage from external sensors, pull resistors, pull-up networks, and indicator circuits. The stated 0.1 µA off current with RAM retention applies to the microcontroller condition described in the datasheet and does not represent complete-system consumption. Disable unused ports and peripherals, avoid floating inputs, and measure the assembled board in its intended operating state to establish the real standby budget.
Keep analog acquisition paths short, shield them from switching nodes, and use a quiet reference arrangement for mixed-signal measurements. The 8 MHz digital clock and switching peripherals can couple into sensitive inputs even when the firmware is efficient. Route analog signals away from the basic clock module and MCU supply pins, use a continuous ground reference, and evaluate the completed layout for sensitivity to switching activity rather than relying only on schematic placement.
