CY8C3445AXE-097 - 50MHz 32KB Flash 8-Bit MCU | Infineon
料号： CY8C3445AXE-097 ✓ 量产中CY8C3445AXE-097 概述
A microcontroller is a programmable semiconductor integrated circuit that executes firmware, reads inputs, controls outputs, and manages system behavior. The CY8C3445AXE-097 sits within the PSoC 3 family, combining an 8-bit 8051 processing core with programmable resources on one mixed-signal chip. This integration allows designers to implement embedded control functions without relying exclusively on external discrete components.
The verified device data identifies a 50 MHz maximum clock frequency and 32 KB, or 32K x 8 bits, of flash memory. Its 100-TQFP package provides 100 physical pins and a 14 mm by 14 mm body size. These package and memory characteristics are the primary selection criteria for designs that cannot use a smaller microcontroller package or require more flash capacity than entry-level devices provide.
The PSoC 3 architecture combines programmable digital blocks, analog functions, and fixed peripherals around the 8051 processor core. That mixed-signal architecture is useful in control panels, instrumentation, communications equipment, and industrial products where analog measurement, digital control, serial communication, and general-purpose processing must coexist in a compact embedded platform.
Typical use cases include industrial monitoring and control, programmable logic, embedded communications, sensor acquisition, and compact consumer or appliance control systems. The 100-pin package is particularly useful when a design requires numerous general-purpose I/O connections, while the 32 KB flash allocation provides a defined code-storage budget for embedded firmware.
Designers should confirm the exact peripheral mix, operating voltage range, RAM capacity, I/O ratings, clock requirements, and package drawing before committing the part to a PCB. The available verified listing does not provide those electrical details, so they must be checked in the official device documentation rather than inferred from the family name.
This page combines verified distributor specifications, sourcing information, package attributes, application guidance, and explicit data gaps. It also distinguishes what is confirmed from what remains unverified, helping engineers identify the next documentation step without presenting unsupported pin, electrical, or compliance claims.

典型应用
CY8C3445AXE-097 适用于 6 应用s: Industrial Equipment Control, Sensor Acquisition and Signal Conditioning, Programmable Logic Controller, Communications Controller, Instrumentation and Measurement, Robotics and Automation Modules.
Industrial Equipment Control
The CY8C3445AXE-097 fits industrial equipment control when a design needs an 8051-compatible embedded processor, 32 KB of flash, and a generous 100-pin package. The verified 50 MHz operating frequency supports responsive firmware execution, while the PSoC 3 mixed-signal architecture can consolidate programmable control and analog functions. Its 14 mm by 14 mm TQFP footprint is larger than typical small-controller packages, but it provides substantial I/O capacity for operator interfaces, sensors, actuators, and status indicators. Engineers should verify supply voltage, timer resources, communications peripherals, and industrial temperature qualification before releasing the design.
推荐
Sensor Acquisition and Signal Conditioning
The CY8C3445AXE-097 can serve as the controller in a programmable sensor-acquisition system because PSoC 3 combines an embedded processor with programmable mixed-signal resources. Its 8-bit 8051 core and 50 MHz maximum clock support firmware-based measurement control, filtering, and data handling, while 32 KB of flash stores application code and calibration tables. The 100-TQFP package offers many external connections for sensors and conditioning circuitry. Before selecting the device, verify the required ADC or DAC resolution, amplifier resources, input ranges, acquisition timing, and whether external signal conditioning is still required.
推荐
Programmable Logic Controller
The CY8C3445AXE-097 is applicable to compact programmable logic and sequencing controllers where deterministic embedded control, configurable digital behavior, and multiple I/O connections are important. Its 8-bit 8051 architecture executes the control program from 32 KB of flash, while the PSoC 3 family provides programmable blocks that can reduce the need for discrete glue logic. The 100-TQFP package is advantageous for systems connecting several inputs, relay drivers, displays, and communications lines. Firmware developers should confirm timer accuracy, interrupt behavior, logic-cell allocation, and output-drive specifications in the official documentation.
推荐
Communications Controller
The CY8C3445AXE-097 can serve as a communications gateway controller when the product requires local protocol handling alongside general embedded functions. Its 50 MHz maximum operating frequency and 32 KB of flash allow firmware to manage message framing, state machines, diagnostics, and configuration storage, while the 100-pin package offers ample connections for a communications interface and supporting control signals. The verified listing does not identify specific UART, SPI, USB, CAN, or Ethernet resources, so the exact protocol peripheral and electrical interface must be confirmed before assigning this device to a communications design.
推荐
Instrumentation and Measurement
The CY8C3445AXE-097 is a candidate for instrumentation and measurement equipment that needs embedded control, configurable mixed-signal functions, and a relatively high pin count. The PSoC 3 architecture can place programmable analog and digital resources close to an 8051 control core, helping designers implement measurement, excitation, filtering, and user-interface functions in one package. Its 32 KB flash budget supports moderate firmware, and the 100-TQFP package accommodates numerous front-panel and external connections. Instrumentation engineers should verify ADC and DAC accuracy, analog noise, reference options, timing precision, calibration support, and operating-temperature limits before selecting the exact device.
推荐
Robotics and Automation Modules
The CY8C3445AXE-097 can be used in compact robotics and automation modules that coordinate sensors, actuators, user controls, and communications through one embedded device. Its 8051 core and 50 MHz clock provide a defined platform for motion-state logic and peripheral coordination, while the PSoC 3 programmable resources offer flexibility for common automation functions. The 100-pin package is especially useful where numerous discrete control connections would otherwise require added logic. Designers must validate timer resolution, pulse-width-measurement resources, interrupt latency, I/O voltage tolerance, and thermal performance under the expected motor and relay switching environment.

设计说明
Use the official 100-TQFP land pattern and verify pin-1 orientation against the current Infineon package drawing before PCB release. The verified listing establishes a 14 mm by 14 mm TQFP body but does not provide the complete pin table, so library selection should not rely only on the generic package name. Also review courtyard, paste mask, solder-profile, and adjacent-component spacing requirements because the exact lead pitch was not included in the supplied data.
Confirm the supported supply range, core and I/O voltage limits, decoupling requirements, and power-consumption characteristics in the official device documentation before designing the power tree. A mixed-signal PSoC design can include switching analog and digital sections, so analog and digital supply filtering should follow the manufacturer reference layout. The verified 50 MHz clock and 32 KB flash figures do not establish supply-current demand, and therefore cannot be used to size regulators or copper.
Plan sensitive analog and communication routes to avoid coupling from digital switching nodes, high-current outputs, clocks, and external switching regulators. Place required input, output, analog, and bypass capacitors at the pins identified by the official reference design; their values were not present in the verified data and must not be guessed. A quiet ground and power partitioning strategy is especially important when the PSoC 3 analog resources are used for precision measurement rather than simple digital control.
Do not treat a device with the same PSoC 3 family name as a drop-in replacement without comparing its complete ordering code, package revision, pinout, memory map, clocking, peripherals, and startup behavior. The supplied cross-reference results contain general lookup tools but no verified replacement MPN. Before a board substitution, compare the old and new devices' errata, configuration requirements, firmware, and mixed-signal block availability, then perform hardware and firmware regression testing.
合规信息
The supplied verified listings do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These values must be confirmed from the current manufacturer product documentation or declaration.
