MPN: CY8C3445AXE-107 ✓ AktifCY8C3445AXE-107 Genel Bakış
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripheral functions into one device. The CY8C3445AXE-107 is specifically an 8-bit MCU with an 8051 instruction-set core. In the product hierarchy, it is an MCU, then a general-purpose embedded processor, and ultimately a semiconductor designed for compact control and monitoring systems. Its 50 MHz clock rate supports faster instruction execution than lower-frequency 8-bit MCUs while retaining a compact architecture.
The principal verified features of this device include 32 KB flash memory organized as 32K x 8, 8-bit processing, 50 MHz maximum operating frequency, and a 1.71 V to 5.5 V supply range. The 100-TQFP package provides 100 external connection points and is suitable for automated board assembly. These characteristics make the part applicable to embedded controls, consumer products, industrial equipment, and connected peripherals that require a modest code-memory footprint and broad supply compatibility.
The CY8C3445AXE-107 combines an embedded MCU with programmable system functionality associated with the PSoC 3 family. The verified distributor description identifies the device as an 8051 PSoC 3 CY8C34xx MCU. Its operating voltage range allows integration with 1.8 V, 2.5 V, 3.3 V, and 5 V system rails when the associated clock, memory, and peripheral requirements are met. A 50 MHz operating specification provides a useful benchmark for firmware performance, interrupt latency, and peripheral timing.
Typical uses include embedded control panels, sensor hubs, motor and actuator controllers, communication modules, and compact consumer appliances. The MCU can execute application firmware from its 32 KB flash memory while coordinating external sensors, communications, and power-control components. For a board-level design, engineers should verify the complete pin mapping, clock requirements, and peripheral configuration against the manufacturer datasheet before finalizing the PCB.
The most important design consideration is power-rail compatibility: the accepted input range is 1.71 V to 5.5 V, so the external supply must remain within that interval under transient and tolerance conditions. Designers should also place required bypass and decoupling capacitors close to the supply pins, route clock signals away from noisy switching nodes, and preserve the component's exposed thermal-relief and soldering requirements.
This page consolidates distributor availability, verified device specifications, application guidance, and pin-compatible family alternatives. The practical benefit is a concise engineering reference that distinguishes known parameters from information that still requires confirmation from the manufacturer datasheet, helping designers evaluate the CY8C3445AXE-107 before committing a PCB footprint.

Tipik Uygulamalar
CY8C3445AXE-107 için uygundur 6 uygulamas: Embedded Consumer Control, Industrial Sensor Hub, Motor and Actuator Controller, Communication Adapter, Power and Charging Controller, Programmable Logic Controller.
Embedded Consumer Control
The CY8C3445AXE-107 fits compact consumer-control boards that require an 8-bit processor, moderate firmware storage, and a broad supply range. Its 32 KB flash provides space for control logic, configuration data, and communication routines, while the 50 MHz rating supports responsive state-machine execution. The 1.71 V to 5.5 V operating range simplifies compatibility with common low-voltage system rails and mixed-voltage interfaces. Designers can use the 100-TQFP footprint when adequate I/O and routing density are valuable. Before layout release, verify the exact pin assignments, clock requirements, and peripheral constraints in the manufacturer datasheet, then implement local decoupling close to the supply pins.
Önerilen
Industrial Sensor Hub
The CY8C3445AXE-107 is suitable for a sensor-hub controller that gathers readings, applies filtering, and forwards status to a host processor. Its 32K x 8 flash capacity can hold acquisition routines and protocol handlers, while the 8-bit 8051 architecture supports typical supervisory control tasks. The 50 MHz maximum frequency provides a defined performance target for polling and interrupt-driven operation. A broad 1.71 V to 5.5 V supply range supports integration into industrial boards operating from several common rails. The principal qualification questions are temperature range, EMC resilience, and exact peripheral availability; these must be confirmed before using the device in production equipment.
Önerilen
Motor and Actuator Controller
The CY8C3445AXE-107 can serve as the supervisory controller in a motor, relay, or actuator subsystem where a deterministic embedded state machine coordinates external drivers. The 50 MHz operating specification supports timely task execution, and 32 KB of flash is appropriate for moderate motion sequences, fault handling, and communication code. Its 1.71 V to 5.5 V range can accommodate logic domains commonly found in compact mixed-signal control boards. Because motor environments introduce switching noise and wide transients, designers should separate sensitive routing, add robust supply filtering, and confirm the device's exact I/O and timing configuration against the datasheet rather than inferring pin functions from the family name.
Önerilen
Communication Adapter
The CY8C3445AXE-107 can be used in a compact communication adapter that converts host commands into configuration updates or peripheral control actions. Its 32 KB flash supports protocol framing, command validation, and device-state storage, while the 50 MHz 8051 core provides a useful rate for packet processing. The 1.71 V to 5.5 V operating range offers flexibility when the adapter interfaces with 1.8 V, 3.3 V, or 5 V system sections. For dependable communication, the board should provide stable clocking, correct termination, and uninterrupted power. Firmware engineers should also verify the exact UART, timer, and port resources required for the selected interface because those details were not present in the supplied listing snippets.
Önerilen
Power and Charging Controller
The CY8C3445AXE-107 is appropriate for supervisory power-system blocks that monitor operating conditions and coordinate protection, load switching, or charger state. The 32 KB flash capacity can accommodate state tables, fault logs, and update routines, while the 50 MHz rating supports fast decision-making around sampled signals. Its supply-voltage range of 1.71 V to 5.5 V allows use as a low-voltage logic controller alongside higher-voltage switching stages. The design must keep noisy power stages separate from sensitive routing and provide local input filtering. Engineers should also validate the MCU's exact analog capabilities, timer resources, and maximum pin tolerances against the manufacturer datasheet before assigning a safety-related role.
Önerilen
Programmable Logic Controller
The CY8C3445AXE-107 can act as the central controller in a compact programmable logic panel with discrete inputs and outputs. An 8-bit MCU is often sufficient for deterministic relay sequencing, interlocks, status-lamp control, and local diagnostics, while 32 KB of flash provides capacity for structured application logic. The 50 MHz rating helps maintain predictable task execution across multiple peripheral events. The 100-pin TQFP package offers many external connections for compact boards, but every assigned signal must be checked against the verified package pinout. A robust PLC implementation should also include watchdogs, safe-state defaults, input debouncing, and supply supervision where required by the machine-safety design.

Tasarım Notları
Keep the CY8C3445AXE-107 supply within the verified 1.71 V to 5.5 V range under tolerance, startup, and transient conditions. Place the manufacturer-required input bypass capacitors directly beside the corresponding supply pins and keep their return paths short. The supplied data does not specify the required capacitance, so designers must obtain the official values from the manufacturer datasheet rather than select a generic value from an unrelated MCU.
Use the 100-TQFP land pattern and pin-1 orientation defined by the manufacturer package drawing. Because the complete pinout was not available in the supplied source, do not assign signals solely from the MPN or package dimensions. Check every power, ground, programming, clock, and peripheral connection against the current datasheet before Gerber release, and confirm that the assembly process supports the 14 x 14 mm TQFP footprint.
Route clock and high-speed signals away from switching nodes, relay drivers, and power-conversion inductors. Provide a quiet return path for sensitive inputs and use local filtering when external connectors can introduce transients. The 50 MHz figure is the processor's maximum operating frequency, so the actual clock source, distribution method, and any required timing margins must be validated against the electrical characteristics in the manufacturer datasheet.
Do not substitute CY8C3445AXC-107 or CY8C3445AXI-107 solely because the package and headline memory rating match. The ordering suffix can represent a different temperature, qualification, or configuration requirement, and the supplied data does not expose those limits. Also avoid treating CY8C3444AXI-116 as a direct replacement because its verified flash capacity is only 16 KB compared with 32 KB for the target.
Uyumluluk Bilgisi
The supplied distributor results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because this product is presented as a general-purpose microcontroller rather than an explicitly automotive-qualified part. Confirm all declarations on the current manufacturer product page and applicable material declarations.
