MSP430F149CY - 16-Bit 8MHz Mixed-Signal MCU | Texas Instruments
料号： MSP430F149CY ✓ 量产中MSP430F149CY 概述
A mixed-signal microcontroller combines a digital processor with analog and communication peripherals on one integrated device. The MSP430 CPU uses a 16-bit RISC architecture and provides the processing foundation for control firmware, while the ADC enables direct measurement of analog inputs without a separate external converter. In the power-management hierarchy, the MSP430 family targets embedded systems where low power consumption and compact integration are important.
The verified MSP430F149 family information identifies an 8 MHz clock, 60 KB of Flash program memory, 2 KB of SRAM, a 12-bit ADC, a comparator, SPI, and UART/USART connectivity. The MSP430F14x family also provides two 16-bit timers and a hardware multiplier, while the MSP430F149 specifically supports two USARTs. These peripherals reduce external component count and provide useful mixed-signal integration for sensor, control, and data-acquisition products.
The MSP430F149CY is identified in distributor results as an MSP430x1xx mixed-signal microcontroller with a 16-bit CPU, 8 MHz speed, and 60 KB Flash memory. The C Y suffix and the distributor listings indicate the packaged ordering variant, while the exact temperature range, voltage limits, pin names, package dimensions, and electrical limits were not supplied in the verified data and must be confirmed from the manufacturer datasheet before design release.
Typical applications include battery-powered industrial sensors, portable measurement instruments, building and environmental monitoring, motor or actuator control, low-power data loggers, and connected embedded systems. The ADC supports analog sensor conditioning, and the two USARTs support external sensors, radios, displays, or host controllers. The SPI interface can connect to higher-speed peripherals when the application requires it.
Designers should budget analog conditioning around the ADC, validate the exact MSP430F149CY pinout and package details, and confirm clock, memory, peripheral, and power requirements against the TI datasheet. This page synthesizes the verified distributor and manufacturer information, while clearly separating unavailable technical values from confirmed specifications.

典型应用
MSP430F149CY 适用于 6 应用s: Battery-Powered Environmental Sensors, Industrial Data Acquisition, Portable Measurement Instruments, Low-Power Motor and Actuator Control, Connected Sensor Hubs, Building Automation and Monitoring.
Battery-Powered Environmental Sensors
The MSP430F149CY fits environmental monitoring designs that combine sensor acquisition, local control, and low-power communications. Its 12-bit ADC can digitize suitable sensor signals, while the 60 KB Flash provides room for firmware, calibration tables, and communication routines. The 2 KB SRAM supports buffering and control logic, although the exact memory limit must be checked against the application state requirements. With the integrated comparator, timers, and serial interfaces, the device can supervise thresholds and transmit measurements through UART or SPI-connected peripherals. Low-current performance values were not supplied in the verified data and should be confirmed in the TI datasheet before sizing the battery.
推荐
Industrial Data Acquisition
The MSP430F149CY is suitable for compact industrial data-acquisition equipment that needs analog measurement and embedded processing in one controller. The 12-bit ADC handles sensor and control-loop inputs, while the two 16-bit timers support periodic sampling, timing, and actuator control. SPI can connect to higher-speed converters or storage, and the two USARTs can serve external instruments or service ports. The 60 KB Flash and 2 KB SRAM provide a useful resource balance for local firmware and buffering. Designers should verify ADC input range, sampling behavior, isolation requirements, and electrical limits from the manufacturer documentation before selecting the device for industrial safety or precision applications.
推荐
Portable Measurement Instruments
The MSP430F149CY can serve portable instruments where a low-power controller must acquire analog signals and manage a local user or communications interface. Its mixed-signal integration reduces the need for separate digital control and ADC components, while the hardware multiplier and 16-bit CPU support efficient signal and control computations. The two USARTs can connect to a display, host, or configuration interface, and SPI can support external memory or acquisition components. The verified data does not provide ADC resolution details beyond 12-bit, input-channel count, noise performance, or reference voltage, so those specifications must be checked before setting measurement accuracy targets.
推荐
Low-Power Motor and Actuator Control
The MSP430F149CY can be used in actuator-control systems that require embedded timing, sensor feedback, and serial coordination. The two built-in 16-bit timers provide timing resources for PWM-related control, periodic measurement, or sequencing, while the comparator can assist with threshold detection and protection functions. The 12-bit ADC supports feedback from position, current, or environmental sensors, and the USARTs can connect to a higher-level controller or diagnostics interface. Exact timer modes, PWM resolution, ADC acquisition time, and output-drive ratings were not provided in the verified data and must be verified before defining motor-drive timing or protection thresholds.
推荐
Connected Sensor Hubs
The MSP430F149CY is appropriate for a small sensor hub that aggregates measurements from local sensors and forwards information through a serial link. Its two USARTs can support multiple device roles, SPI can connect to a sensor or storage device, and the ADC handles compatible analog channels in a compact embedded design. The 60 KB Flash is useful for protocol handling and configuration storage, while the 2 KB SRAM can hold short-lived measurement and protocol data. Because the verified information does not specify USB, Ethernet, radio integration, or exact pin multiplexing, the design should use an external companion for those functions and validate power and signal integrity on the final PCB.
推荐
Building Automation and Monitoring
The MSP430F149CY can support building-automation nodes that monitor analog environmental conditions and coordinate local equipment. The 12-bit ADC is useful for temperature, light, occupancy, or other sensor inputs after appropriate signal conditioning, and the two USARTs can communicate with building controllers or sensor nodes. The hardware multiplier and timers can support local filtering, periodic sampling, and control logic, while the integrated comparator can monitor thresholds. The exact low-power modes and current consumption are not provided in the verified data, so battery sizing and maintenance intervals require confirmation from the MSP430F149 documentation and a representative hardware test.

设计说明
Confirm the exact supply range, operating current, and sleep-current behavior in the TI MSP430F149 datasheet before selecting the device for a battery-powered design. The verified data confirms 2.5 V to 3.3 V operation but does not provide current-consumption figures. Use the MCU's low-power modes only after checking the required startup time, ADC availability, timer behavior, and serial-interface state retention.
Use a manufacturer-approved land pattern for the exact MSP430F149CY package and verify pin 1 orientation, pad dimensions, and exposed-pad requirements before PCB release. The verified results identify a 48-I/O mixed-signal MCU but do not provide the complete pinout. Keep analog inputs away from high-current switching paths, provide local decoupling at the supply pins, and route ground returns according to the TI recommended layout.
Do not treat MSP430F149 and MSP430F149CY as interchangeable solely from their similar names. Check the TI ordering information for package, temperature grade, qualification, and lifecycle details. Also verify the ADC input range and acquisition timing, USART multiplexing, timer pin assignments, and supply tolerances against the complete datasheet before freezing firmware and PCB interfaces.
合规信息
The supplied verified web data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than inferred.
