MSP430F2012IN - 16MHz 2KB Flash 128B SRAM MCU | Texas Instruments
Référence : MSP430F2012IN ✓ ActifMSP430F2012IN Présentation
The MSP430 architecture is a mixed-signal MCU family in which the CPU, analog conversion, timers, communication peripherals, and low-power modes are integrated for compact instrumented systems. The 16-bit CPU supports efficient interrupt-driven control and deterministic timing, while the integrated 10-bit ADC reduces the need for external analog front-end components in battery-powered measurement designs.
Key features of the MSP430F2012IN include a 16 MHz maximum clock rate, 2 KB program Flash, 128 B SRAM, a 10-bit ADC, timer resources, I2C, and SPI. The 14-pin PDIP package is suited to through-hole prototyping, legacy industrial controllers, and designs where a socketed or hand-soldered microcontroller package is more practical than a surface-mount alternative.
The MSP430F2012IN is intended for applications such as low-cost sensor nodes, industrial measurement modules, portable instruments, simple motor and actuator controllers, battery-powered monitors, and compact embedded control boards. Its small memory footprint makes firmware design and code size important considerations, while the mixed-signal peripherals simplify designs that require measurement and serial communication.
A key design consideration is that the MSP430F2012IN is a small-footprint MCU with limited RAM and Flash. Applications should keep working buffers small, use efficient interrupt routines, and avoid relying on libraries that require substantial memory. A decoupling capacitor should be placed close to the supply pins, and unused inputs should be configured appropriately.
This product page combines the verified 16 MHz, 2 KB Flash, 128 B SRAM, 10-bit ADC, timer, I2C, SPI, and 14-pin PDIP information with procurement, comparison, and engineering guidance. It is intended to help engineers confirm fit, plan firmware constraints, and evaluate supply-chain options before designing a new board.

Applications typiques
MSP430F2012IN convient pour 6 applications: Battery-Powered Sensor Nodes, Industrial Measurement and Control, Portable Instrumentation, Simple Motor and Actuator Control, Embedded Data Acquisition, Prototype Embedded Control Boards.
Battery-Powered Sensor Nodes
The MSP430F2012IN is appropriate for compact sensor nodes that require analog measurement and serial connectivity without a separate digital signal processor. Its integrated 10-bit ADC can acquire analog sensor conditions, while the timer supports periodic sampling and wake-up control. The 16 MHz MSP430 core provides enough instruction throughput for interrupt-driven filtering, while the 2 KB Flash and 128 B SRAM require compact firmware. I2C and SPI allow connection to external sensors, memory, or transceivers. A practical design should use the low-power operating modes, measure average current with the intended sensor load, and verify startup and wake-up timing in the manufacturer datasheet.
Recommandé
Industrial Measurement and Control
The MSP430F2012IN supports small industrial measurement modules where a 16-bit MCU, 10-bit ADC, timer, and serial interfaces are required in a limited board area. The DIP package simplifies through-hole assembly and prototype revisions, and the operating range of -40 C to +85 C is stated in the verified product data. Use the ADC for process-signal monitoring, the timer for acquisition timing, and I2C or SPI for external sensors and digital peripherals. Because memory is limited to 2 KB Flash and 128 B SRAM, avoid large display or protocol stacks and keep interrupt handling deterministic. Verify the exact supply voltage, ADC performance, and I/O limits in the datasheet.
Recommandé
Portable Instrumentation
For handheld or portable measurement instruments, the MSP430F2012IN combines a 16-bit CPU with a 10-bit ADC, timer, I2C, and SPI in one 14-pin PDIP device. This allows a prototype to measure a battery-powered or external sensor and communicate with a display or data logger. The through-hole package is particularly useful when the product is assembled manually or uses socketed boards. Firmware should use the limited SRAM carefully by streaming data instead of buffering large sample sets. The ADC reference, input channels, conversion time, and low-power current are not included in the supplied verified data, so those values must be confirmed before defining measurement accuracy or battery-life targets.
Recommandé
Simple Motor and Actuator Control
The MSP430F2012IN can be used for small actuator-control boards that require deterministic timing, digital I/O, and basic analog feedback. The 16 MHz core and integrated timer provide a platform for timer-based control loops, while the ADC can monitor a current, position, or supply-feedback signal. I2C and SPI permit connection to sensors, H-bridge controllers, or external logic. The 14-pin PDIP footprint makes the part easy to prototype and replace during early hardware bring-up, although it consumes more board area than a surface-mount option. Firmware and PCB designs must account for the 2 KB Flash and 128 B SRAM limits, and motor-noise immunity must be evaluated with appropriate grounding and decoupling.
Recommandé
Embedded Data Acquisition
The MSP430F2012IN is suitable for small data-acquisition front ends where a 10-bit ADC, timer, and serial communications are sufficient. The timer can establish sampling intervals, the ADC can digitize one or more analog inputs, and I2C or SPI can transfer results to a host controller. The DIP package allows straightforward socketed prototyping and rework, while the MSP430 family's mixed-signal integration reduces the component count compared with a discrete ADC design. Design the acquisition chain around the exact ADC input range and reference voltage from the datasheet, calibrate the sensor path as required, and avoid storing large sample buffers because only 128 B of SRAM is available.
Recommandé
Prototype Embedded Control Boards
The MSP430F2012IN is well suited to educational prototypes, proof-of-concept boards, and legacy-style controller bring-up where a through-hole MCU package is easier to install and replace. Its 16 MHz execution rate and integrated timer, ADC, I2C, and SPI allow a single chip to support sensing, timing, and peripheral communication. The 14-pin PDIP footprint gives clear access to pins for oscilloscope probing and logic-analysis work, and the -40 C to +85 C temperature rating covers industrial ambient conditions. Plan memory carefully from the beginning: 2 KB Flash limits firmware size, and 128 B SRAM limits buffering and library overhead. Validate supply voltage and unused-pin states directly from the datasheet.

- Documented industrial ambient range (vs MSP430F2012)
Notes de conception
Place the supply bypass capacitor as close as practical to the MSP430F2012IN power pins and keep the analog and digital return path continuous. Because the supplied verified data does not state the recommended capacitor value, supply-voltage range, or quiescent current, use the decoupling and current-budget recommendations in the manufacturer datasheet rather than copying values from another MSP430 device.
Do not treat MSP430F2012IPWR as a mechanical drop-in for MSP430F2012IN. The verified listings identify MSP430F2012IN as 14-pin PDIP and MSP430F2012IPWR as 14-pin TSSOP. Although both are MSP430F2012-family devices, the footprints and assembly processes differ, and a DIP-hole PCB requires a layout or adapter change before using the TSSOP version.
The 2 KB Flash and 128 B SRAM are the dominant constraints in an MSP430F2012IN design. Use compact data structures, avoid large protocol or floating-point libraries, stream sampled data rather than buffering it, and estimate worst-case stack usage before adding interrupts. Confirm the final code size and RAM map with the compiler/linker because the verified distributor snippets do not provide the device's detailed memory-map values.
For ADC-based designs, route the sensor input away from switching nodes and keep the return path under the analog front end. The verified data confirms a 10-bit ADC but does not specify input impedance, acquisition time, reference accuracy, or channel multiplexing, so the source impedance and sampling strategy must be selected from the datasheet rather than inferred from the 16 MHz CPU clock.
Informations de conformité
The supplied verified sources identify the product, package, memory, clock, ADC, timer, serial interfaces, and temperature range, but they do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Confirm these attributes on the Texas Instruments product page or with the supplier.
