부품 번호: CY8C3846AXE-175 ✓ 활성CY8C3846AXE-175 개요
A microcontroller is a semiconductor integrated circuit containing a processor core, nonvolatile program memory, data memory, and peripherals on one die. In the broader IC hierarchy, the CY8C3846AXE-175 belongs to the embedded-microcontroller category and provides a compact platform for combining control logic with analog functions. Its 8051 architecture and PSoC 3 family position it between simple fixed-function controllers and higher-performance 32-bit microcontrollers.
The principal verified features include a 48 MHz operating frequency, 64 KB of flash organized as 64K x 8 bits, 8-bit processing, and a 100-TQFP gull-wing package. Distributor records also identify 2.5 V, 3.3 V, and 5 V operating options for this device family. Its 100 terminals provide a substantial number of external connections compared with smaller 8-, 16-, or 32-pin microcontroller packages, supporting integration into control and mixed-signal systems that require numerous I/O resources.
The CY8C38xx architecture combines an 8051-compatible core with programmable analog blocks, digital blocks, and programmable system resources. This enables designers to consolidate functions that might otherwise require separate analog and digital ICs. The 64 KB flash capacity provides sufficient on-chip storage for embedded firmware, while the 48 MHz clock rate supports responsive control and measurement routines. However, it remains an 8-bit MCU rather than a 32-bit processor, so workloads requiring large data movement, complex operating systems, or high computational bandwidth may benefit from a more capable platform.
Typical uses include industrial control panels, building automation modules, sensor interfaces, motor and power-control systems, consumer appliances, and compact embedded instruments. The high pin count can reduce external glue when a design needs numerous GPIO, communication, control, or analog connections. Firmware and board validation remain essential because peripheral availability, routing, and operating conditions depend on the selected PSoC configuration.
Designers should use the manufacturer datasheet for the definitive pin map, electrical limits, programming requirements, and exposed-pad connection details. Layout planning should preserve the required decoupling structure, provide clean grounding for sensitive analog measurements, and route high-speed or switching signals away from precision analog inputs. Firmware should also include startup and brownout behavior appropriate to the selected supply range.
This product record consolidates verified distributor specifications, current commercial information, and practical engineering guidance. It also distinguishes confirmed facts from unavailable details rather than inferring pin assignments, electrical limits, lifecycle guarantees, or cross-references that are not present in the supplied source data.

Industrial Control and Automation
The CY8C3846AXE-175 fits compact industrial control modules that need a 48 MHz 8051-compatible core, 64 KB of flash, and numerous external connections in a 100-pin TQFP package. Its PSoC 3 architecture can consolidate programmable analog and digital functions around a single microcontroller, reducing the need for separate interface devices. The verified 0.5 V to 5.5 V range also provides flexibility across common industrial supply levels. For a production design, validate input thresholds, ESD protection, isolation boundaries, and timing margins against the manufacturer datasheet. The supplied minimum operating temperature is -40 C, but industrial qualification requirements may be more demanding.

Building Automation and Environmental Control
The CY8C3846AXE-175 is appropriate for building-control nodes that combine sensor conditioning, digital logic, and communications in a space-constrained board. Its 48 MHz processing speed supports responsive control tasks, while 64 KB of flash can hold embedded application firmware. The 100-pin package offers ample GPIO and peripheral routing options for temperature, occupancy, lighting, or actuator interfaces. PSoC 3 programmable resources can help reduce external component count, although the final partitioning depends on the selected device configuration and available analog routing. Firmware must preserve correct startup behavior and configured peripheral clocks, while PCB layout should separate sensitive analog inputs from switching nodes and communication return currents.
추천
Industrial Sensor Interface
The CY8C3846AXE-175 can serve as the control hub for a multi-sensor industrial module because its PSoC 3 architecture combines an 8-bit, 48 MHz MCU with programmable system resources. The 64 KB flash capacity accommodates embedded firmware for calibration, filtering, diagnostics, and data formatting, while the 100-pin TQFP package supports numerous inputs and outputs. The supplied records confirm a 0.5 V to 5.5 V operating range, making the device suitable for carefully designed low- and higher-voltage sensor interfaces. Engineers must verify each analog block's usable range and routing in the manufacturer documentation, apply suitable input protection, and avoid assuming that nominal MCU I/O limits directly apply to every sensor signal.
추천
Motor and Power-System Control
The CY8C3846AXE-175 is suited to supervisory control in motor drives, power supplies, and actuator modules where an 8051-compatible 48 MHz controller must coordinate multiple digital signals. Its PSoC 3 resources can be configured to reduce the number of external building blocks, and the 100-pin package provides substantial connectivity for status inputs, fault signals, and gate-control interfaces. The MCU should supervise rather than directly absorb high-power switching energy. Designers must provide suitable gate drivers, protection networks, isolation where required, and fault-safe shutdown behavior. All timing and electrical limits must come from the exact manufacturer documentation because the supplied search results do not provide PWM, ADC, or absolute-maximum ratings.
추천
Communication and Protocol Interface
The CY8C3846AXE-175 works as a protocol-facing microcontroller in compact communications equipment requiring deterministic embedded control, 64 KB of flash, and a high pin count. Its 8051-compatible 48 MHz core can manage framing, timers, status reporting, and configuration while PSoC peripherals support analog or digital interface functions. The 100-pin TQFP package makes it practical to expose multiple interface and control signals without an external large-lead-count device. For RS-485, CAN, or other physical-layer links, use a qualified transceiver and verify the MCU port mapping, interrupt behavior, and electrical limits in the manufacturer documentation. Isolation, termination, surge protection, and grounding must be designed at the board level rather than assumed from the MCU specification.
추천
Consumer Appliance and Embedded Products
The CY8C3846AXE-175 can serve as the main controller in appliances, compact instruments, and other embedded products where a low-cost 8-bit MCU must combine control logic with programmable mixed-signal functions. Its 48 MHz operating rate provides responsive handling of user inputs and actuators, and 64 KB of flash supports embedded application code. The 100-pin TQFP package is larger than a minimal controller package but offers many routed connections for displays, switches, sensors, and communication ports. Product designers should evaluate whether the available package and internal resources justify the footprint, and should verify EMC, ESD, temperature, and lifecycle requirements before release. JEDEC test information and exact timing characteristics were not included in the supplied source data.

설계 노트
Treat the 100-pin TQFP footprint and its exposed thermal structure as a high-pin-count fine-pitch layout. Follow the exact manufacturer land pattern, pin-1 orientation, solder mask, and paste recommendations rather than relying on a generic LFQFP drawing. Provide local input and output decoupling close to the corresponding supply pins, preserve a continuous ground reference, and route sensitive analog inputs away from digital clocks and switching-node copper. Check the package drawing and PCB library against the exact ordering code before fabrication.
Design the supply rails for the confirmed 0.5 V to 5.5 V device range and the particular internal configuration used by the application. PSoC configuration, active peripherals, I/O loading, and clocking can affect supply demand, so evaluate worst-case demand rather than only average current. Use the manufacturer guidance for bypass capacitance, startup, brownout, and sequencing. Do not infer analog or I/O operating limits from the headline supply range; each rail and pin must satisfy the datasheet limits.
Plan analog and digital signal routing before assigning PSoC functions because internal routing and external pin multiplexing can constrain implementation options. Keep sensor traces short, guard them with an appropriate ground reference, and isolate high-impedance analog paths from clock, pulse-width-modulation, and switching-converter nodes. For communication or control interfaces, verify signal timing, interrupt latency, and peripheral mapping in the manufacturer documentation. Validate the assembled board with the intended clock, load, temperature, and supply conditions.
Do not substitute a generic 48 MHz, 64 KB-flash MCU without checking the complete pinout, memory map, peripheral set, interrupt vectors, startup sequence, clock configuration, and development-tool support. Equal clock rate and flash size do not make two devices firmware- or pin-compatible. Similarly, do not treat the X suffix, temperature grade, or package code as interchangeable without reviewing the Infineon ordering guide. This caution is especially important because the supplied sources did not expose a verified cross-reference replacement.
