MSP430F2618TPM - 16MHz 16-Bit MCU 116KB Flash | Texas Instruments
MPN： MSP430F2618TPM ✓ 啟用中MSP430F2618TPM 概覽
A mixed-signal microcontroller combines digital control logic with analog conversion and communication peripherals on one device. In the MSP430 family, the CPU, memory, ADC, DAC, serial interfaces, and low-power hardware are integrated into a compact package. This reduces component count and simplifies firmware-driven sensing and control compared with separate microcontroller, converter, and interface devices. The MSP430F2618TPM is therefore positioned between general-purpose control and dedicated signal-processing applications.
The device operates from a 2.2 V to 3.6 V supply and provides 64 I/O ports according to the product listing. Its 16 MHz maximum clock supports deterministic control loops and efficient processing of sampled data. The 116 KB flash memory provides 116K x 8 storage plus 256 bytes, while 8 KB of SRAM supports working data, stack space, and buffered acquisition results. A hardware multiplier accelerates multiply operations, and DMA reduces CPU involvement during peripheral transfers.
The integrated 12-bit ADC supports analog measurement, and the dual 12-bit DAC supports programmable analog output for control, excitation, signal generation, or test systems. I2C and SPI suit sensor and peripheral expansion, while UART supports serial communication with host systems, debug tools, or industrial equipment. These peripherals make the MCU useful for sensor acquisition, industrial instrumentation, data loggers, portable measurement equipment, and embedded control panels.
The main design consideration is power management. The MSP430 offers multiple low-power operating states, so firmware can remain in a low-current state between measurements and activate the CPU and peripherals only when data is required. Keep the supply within 2.2 V to 3.6 V, observe the recommended decoupling and analog-layout practices in the manufacturer datasheet, and verify the exact pin assignment and peripheral multiplexing for the LQFP-64 footprint before layout release.
This product page combines the manufacturer’s core device description, verified distributor specifications, package information, practical design guidance, and clearly qualified replacement considerations for engineers evaluating MSP430F2618TPM-based designs.

典型應用
MSP430F2618TPM 適用於 6 應用s: Portable Data Logger, Industrial Sensor Acquisition, Process Control Instrument, Battery-Powered Instrument, Communications Gateway, Precision Analog Signal Generator.
Portable Data Logger
The MSP430F2618TPM fits portable data loggers because its 16 MHz 16-bit CPU can process sensor data while five low-power modes reduce activity between capture events. The 116 KB flash provides substantial firmware and calibration storage, and the 8 KB SRAM supports acquisition buffers and working variables. Its 12-bit ADC acquires analog measurements, while UART provides a path to a host or data-transfer module. Power-budget the system around the device’s 2.2 V to 3.6 V operating range and use the low-power modes to extend battery life.
推薦
Industrial Sensor Acquisition
The MSP430F2618TPM is appropriate for industrial sensor acquisition because it combines a 12-bit ADC, 64 I/O ports, and I2C, SPI, and UART in one mixed-signal device. Firmware can sample sensors, apply filtering and calibration, and communicate results over a local serial bus or UART. The 16 MHz CPU supports responsive control and the hardware multiplier accelerates arithmetic-intensive processing. Validate the analog input limits, channel multiplexing, and 2.2 V to 3.6 V supply behavior against the manufacturer datasheet before production.
推薦
Process Control Instrument
The MSP430F2618TPM can serve as the control core in a process-control instrument where analog monitoring and programmable analog output are both required. The 12-bit ADC can sample a process variable, the dual 12-bit DACs can drive control or excitation outputs, and the 16-bit CPU can execute proportional, integral, and derivative calculations. Serial interfaces allow connection to sensors, displays, or service equipment. Confirm loop timing, DAC output loading, and control stability in the target system rather than relying only on nominal converter resolution.
推薦
Battery-Powered Instrument
The MSP430F2618TPM is designed for portable measurement systems that benefit from a 16-bit RISC CPU and five low-power modes. The processor can remain in a low-power state between readings, while the ADC, DAC, and communication peripherals operate when data is required. Its 8 KB SRAM is suitable for compact working sets, and the 116 KB flash supports firmware, calibration tables, and logged configuration data. For battery optimization, measure actual sleep and active currents on the assembled design, including sensor and interface loads.
推薦
Communications Gateway
The MSP430F2618TPM can be used in a compact communications gateway when a design requires both serial-interface flexibility and low-power operation. I2C and SPI support local sensor or transceiver expansion, UART supports host communication, and DMA can reduce processor involvement during transfers. The 64 I/O ports provide additional status, alarm, and routing signals. Because the exact pin multiplexing depends on the device configuration, assign alternate functions only after checking the MSP430F2618 family pin table and validating the selected firmware configuration.
推薦
Precision Analog Signal Generator
The MSP430F2618TPM can support compact analog signal-generation and test functions because it integrates dual 12-bit DACs with a 16 MHz 16-bit CPU. The CPU can calculate waveform values, update outputs, manage timing, and expose configuration through UART or another serial interface. Its 116 KB flash and 8 KB SRAM permit calibration and buffer storage. The 2.2 V to 3.6 V supply range simplifies low-voltage design integration, but output settling, reference accuracy, noise, and usable bandwidth must be evaluated in the final analog circuit.

主要差異化特點
- Integrated mixed-signal resource set (對比MSP430F2617TPM)
- Same-family ordering alternative (對比MSP430F2618TPMR)
- Dedicated low-power mixed-signal architecture (對比MSP430F2417TPM)
設計說明
Design the MSP430F2618TPM supply rail within the verified 2.2 V to 3.6 V operating range. Place the required bypass capacitors close to the device power pins and keep analog and digital return currents separated where practical. Because the device supports five low-power modes, measure sleep and active current on the complete board, including sensor bias, interface leakage, and pull-up networks.
Use the manufacturer’s 64-LQFP pin-description table to assign ADC, DAC, I2C, SPI, UART, reset, and clock functions before routing the PCB. Keep analog input traces short, isolate them from switching nodes and high-current return paths, and provide a quiet reference arrangement around the analog section. Verify exposed-pad or thermal requirements directly against the official package drawing.
Do not assume that every related MSP430F2xx TPM device has identical memory or peripheral resources. The MSP430F2618TPM is specifically identified with 116 KB flash, 8 KB SRAM, 16 MHz operation, a 12-bit ADC, and dual 12-bit DACs. For any alternative, check the manufacturer’s ordering table, pin multiplexing, memory map, and firmware assumptions before releasing a replacement design.
For serial links and sensor buses, keep I2C and SPI traces short, provide appropriate pull resistors, and route clock or data signals away from analog inputs. When using the ADC or DAC at low signal levels, use a controlled reference and layout, and evaluate noise, settling, and sampling behavior on the assembled system rather than inferring performance from converter resolution alone.
