MSP430G2553CY - 16MHz 16KB Flash Mixed-Signal MCU | TI
부품 번호: MSP430G2553CY ✓ 활성MSP430G2553CY 개요
A mixed-signal microcontroller is an embedded semiconductor that combines a programmable digital controller with analog or sensing functions. In the product hierarchy, this MSP430 belongs to the microcontroller, embedded processor, semiconductor, and mixed-signal controller classes. Its 16-bit MSP430 CPU architecture makes it suitable for compact control systems requiring low power, deterministic peripheral access, and several communication interfaces without a separate analog processor.
The verified device information identifies a 16 MHz operating speed, 16 KB Flash, 512 B SRAM, one comparator, UART/SPI/I2C connectivity, and timers. DigChip additionally lists 24 I/O ports, a 3.3 V to 3.6 V supply range, and a 0.1 µA off-mode current with RAM retention. These figures position MSP430G2553CY for low-power sensing, control, instrumentation, and communications designs where memory and integrated interfaces are more important than high-speed digital processing.
The MSP430G2xx family architecture is oriented toward low-power embedded control. Its integrated comparator supports threshold-based sensing, while UART, SPI, and I2C support connections to sensors, displays, transceivers, and external nonvolatile memory. The timer resources can provide event timing and periodic service functions, but individual timer channels, capture/compare resources, and interrupt assignments must be selected from the MSP430G2x53 datasheet for the exact die.
Typical applications include battery-powered sensor nodes, compact industrial monitors, digital thermometers, environmental measurement systems, motor or actuator controllers, and simple serial gateways. For a new PCB, the CY suffix and die-sale status require careful review: developers should not assume that the QFN-32 package information found in generic listings corresponds to the CY deliverable. Board assembly may instead require the documented die-sale process, bonding method, and package outline.
Before layout, confirm the exact pin assignment and exposed-pad requirements in the official MSP430G2x53 datasheet and with TI. Program development commonly uses an MSP430-compatible toolchain, but the verified data does not identify a specific IDE version, debugger, or programming adapter. Power, ground, decoupling, reset, boot-strapping, communication, and exposed-pad connections should therefore follow the authoritative device documentation rather than generic QFN assumptions.
This page consolidates verified manufacturer and distributor information, separates die-sale ordering facts from generic family specifications, and identifies unresolved package, pricing, pinout, lifecycle, and compliance details instead of guessing. It is intended as an engineering-data starting point for MSP430G2553CY sourcing and design review, not as a substitute for TI's final orderable datasheet and quality documentation.

일반적인 애플리케이션
MSP430G2553CY 적합 용도: 7 애플리케이션s: Battery-Powered Sensor Node, Digital Thermometer and Threshold Monitor, Compact Industrial Data Logger, Simple Actuator and Motor Controller, SPI Master Data Acquisition, Serial Configuration Bridge, Low-Power Environmental Monitor.
Battery-Powered Sensor Node
MSP430G2553CY fits a compact sensing node that periodically reads an analog signal, evaluates it against the integrated comparator, and transmits the result through UART, SPI, or I2C. Its 16 MHz MSP430 CPU provides timing for acquisition and protocol handling, while 16 KB Flash stores firmware and 512 bytes of SRAM supports short working buffers. The reported 0.1 µA off-mode current with RAM retention can help preserve state between measurements, although final battery life depends on the exact CY limits, sensor current, wake interval, and radio duty cycle.
추천
Digital Thermometer and Threshold Monitor
The MSP430G2553CY can supervise a resistive, semiconductor, or external sensor when the measured level must be compared with a threshold. Its integrated comparator supports a low-overhead decision path, while the 16-bit CPU can apply filtering, calibration, hysteresis, and offset correction. The 24 reported I/O ports provide flexible connections for sensor excitation, display control, and status indicators. For accurate results, follow the official family electrical guidance and obtain CY-specific limits because the verified data does not identify comparator timing or input-range details.
추천
Compact Industrial Data Logger
MSP430G2553CY can serve as the control core for a compact logger that samples sensors, timestamps events, stores state, and forwards records through a serial link. Its 512 bytes of SRAM are sufficient for small control and packet buffers, while 16 KB Flash holds application firmware; larger nonvolatile histories require external SPI flash or another storage device. UART is useful for a local host, and I2C or SPI can connect sensors and memories. Production design work must reserve I2C pull-ups and verify bus voltage against the confirmed CY device limits.
추천
Simple Actuator and Motor Controller
The MSP430G2553CY can coordinate a small actuator or motor subsystem by generating timing signals, reading feedback, enforcing limits, and reporting status. Its timers support periodic control tasks, and the comparator can monitor a feedback signal near a threshold. UART or SPI can connect to a host or power stage, while the 24 reported I/O ports provide discrete control and sensing lines. Because the verified information does not specify PWM channels, pin multiplexing, or absolute output limits, pin assignment and drive-current checks must use the exact MSP430G2x53 and CY documentation before power devices are connected.
추천
SPI Master Data Acquisition
MSP430G2553CY can act as an SPI master for sensors, ADCs, displays, and nonvolatile memory, using its 16 MHz CPU to organize transactions and process returned data. The UART interface can provide a separate debug or configuration channel, reducing contention with the SPI bus. Firmware can implement chip-select timing, DMA-like event handling with interrupts, and fault recovery based on the family peripherals. Engineers must verify the exact CY pin mux, maximum SPI clock, and electrical limits before relying on a specific bus rate or peripheral arrangement.
추천
Serial Configuration Bridge
MSP430G2553CY can bridge a legacy local bus to a higher-level controller by translating commands between UART and SPI or I2C peripherals. Its small memory footprint suits protocol conversion, device discovery, register polling, and status aggregation, while the comparator can monitor an external fault signal. The design can sleep between transactions to reduce power and wake through an interrupt-capable interface. Firmware should include protocol timeouts, CRC checking where applicable, bus contention handling, and recovery logic because peripheral multiplexing and wake-capable pins require exact CY validation.
추천
Low-Power Environmental Monitor
MSP430G2553CY can supervise temperature, humidity, light, or gas sensing in a compact environmental monitor. The controller can wake periodically, power or interrogate a sensor, perform threshold decisions, and publish a result through UART, SPI, or I2C. Its 16-bit CPU supports calibration tables and digital filtering, while 512 bytes of SRAM is adequate for bounded measurement buffers. Reported 0.1 µA off-mode current with RAM retention is favorable for duty-cycled operation, but total energy per sample must include sensor, interface, and regulator overhead verified for the complete system.

설계 노트
Do not create a footprint from the generic MSP430G2553 QFN-32 information. MSP430G2553CY is identified as a die sale, so obtain the controlled die dimensions, pad or bonding interface, die orientation, and assembly process from TI. The confirmed mechanical definition must precede PCB layout and production release because a family-package drawing may not represent the CY deliverable.
Use the verified 3.3 V to 3.6 V supply indication only as a family-level planning value until CY-specific limits are confirmed. Place local supply decoupling at the final package or bond interface, provide a clean return path, and size external components for the actual clock and bus loads. Avoid assuming that adjacent MSP430 devices have identical absolute-maximum ratings or power-up behavior.
A common design error is treating MSP430G2553CY as a packaged MSP430G2553. The verified ordering record says die sale, and generic listings mention QFN-32, but neither proves pin compatibility with that package. Another error is substituting another MSP430 based only on 16 MHz and 16 KB Flash; RAM, comparator resources, timers, pin mux, interrupt vectors, and assembly interface must also match.
Confirm which pins support UART, SPI, I2C, comparator inputs, timer capture/compare, interrupts, reset, and debug functions before assigning board signals. Keep sensitive comparator and sensor routes short, maintain continuous ground references, and isolate switching-converter paths from low-level analog inputs. These practices remain important even though the verified data does not provide a CY-specific recommended PCB layout.
For a duty-cycled design, begin the battery budget with the reported 0.1 µA off-mode current with RAM retention, but do not treat it as total system sleep current. Sensor leakage, pull resistors, interface state, regulators, and external memories may dominate consumption. Measure the assembled system across temperature and supply voltage after confirming the electrical limits for the exact die-sale lot.
