CY8C28533-24AXI - 24MHz 16KB Mixed-Signal MCU | Infineon
MPN: CY8C28533-24AXI ✓ AktifCY8C28533-24AXI Genel Bakış
A PSoC, or Programmable System-on-Chip, is an integrated circuit that places a microcontroller core, programmable analog and digital blocks, and configurable peripherals into a single package. The PSoC 1 family belongs to the broader embedded-microcontroller and programmable-logic hierarchy. This integration can reduce the number of discrete components in control boards while allowing software to configure peripheral functions for a particular product.
Verified product information identifies the CY8C28533-24AXI as an M8C-based CY8C28xxx device with 24 MHz operating speed and 16 KB, expressed as 16K x 8, of flash memory. Its feature set includes programmable mixed-signal control, PWM capability, and I2C support. These functions suit compact controllers that must coordinate sensing, timing, actuator drive, and communication without relying on a larger external mixed-signal controller.
The 44-pin TQFP package provides 44 physical leads and supports surface-mount assembly. Its 10 x 10 mm body is substantially larger than the smallest packages but offers more exposed I/O than compact leadless packages. Because the supplied sources do not expose the complete pin map, detailed voltage ratings, RAM capacity, analog conversion performance, and operating-temperature limits should be confirmed in the manufacturer datasheet before schematic release.
Typical uses include industrial keypad and panel controllers, compact motor-control modules, programmable signal generators, sensor-interface boards, and low-cost consumer-control products. In a PWM-based project, the device can generate deterministic control waveforms while using I2C for communication with a sensor or configuration controller. In a compact instrument, the integrated mixed-signal architecture may shorten the design by consolidating multiple peripheral functions.
The primary design consideration is verification of board-level constraints. Engineers should confirm the exact pin assignments, exposed lead functions, decoupling requirements, clock configuration, and programming interface in the manufacturer datasheet. PCB layout should preserve a short ground-return path and place required bypass capacitors adjacent to the appropriate supply pins.
This product record consolidates the verified distributor description, package information, 24 MHz operating speed, 16 KB flash capacity, PWM and I2C positioning, current sourcing information, and application-oriented engineering guidance. It also identifies same-family replacement candidates separately from verified cross-brand equivalents so procurement and design-review decisions remain traceable.

Tipik Uygulamalar
CY8C28533-24AXI için uygundur 6 uygulamas: Industrial Control Panels, Compact PWM Motor Controllers, Programmable Sensor Interfaces, Low-Cost Consumer Controls, Instrumentation and Signal Generation, Communication-Assisted Embedded Modules.
Industrial Control Panels
The CY8C28533-24AXI fits compact industrial control panels because its 24 MHz M8C processor can coordinate button or encoder inputs, indicator logic, timers, and serial configuration while programmable mixed-signal resources handle analog conditioning. The verified 16 KB flash budget is suitable for a focused embedded controller rather than a large graphical user interface. A 44-TQFP package also provides 44 leads for external control signals and debugging. The practical trade-off is that the complete pin map and peripheral limits are unavailable in the supplied records, so the schematic must be based on the manufacturer pin table. Confirm I/O ratings, ADC performance, clock setup, and supply constraints before releasing an industrial board.
Önerilen
Compact PWM Motor Controllers
The CY8C28533-24AXI is suitable for small PWM-based motor or solenoid controllers because its verified 24 MHz execution speed provides dedicated timing capacity and the device is explicitly identified as supporting PWM. Firmware can generate control waveforms, read feedback inputs, and manage an I2C command or sensor interface within one compact controller. The 16 KB flash capacity supports a focused control algorithm rather than a complex high-level operating system. Before selecting it for a motor design, engineers should verify timer resolution, output-pin electrical limits, PWM frequency, and whether the external driver interface matches the board. The MCU should remain separate from the power stage and use protection appropriate to the load.
Önerilen
Programmable Sensor Interfaces
The CY8C28533-24AXI can serve as the control center of a compact sensor-interface board where analog signals must be digitized or compared and the result is used to operate another subsystem. Its programmable mixed-signal architecture and 24 MHz 8-bit M8C core are appropriate for thresholding, filtering, calibration, and actuator decisions in a focused embedded product. I2C support allows the MCU to communicate with a sensor or configuration IC, while 16 KB flash can hold application firmware and constants. The source records do not confirm ADC resolution, input count, accuracy, or input bandwidth, so those parameters must be verified before defining measurement performance. External filtering and grounding should be designed around the selected analog pins in the manufacturer documentation.
Önerilen
Low-Cost Consumer Controls
The CY8C28533-24AXI can implement a low-cost product controller for appliances, hobby equipment, or compact accessories where a dedicated 8-bit processor, PWM, I2C, and mixed-signal integration provide a practical balance of capability and cost. Its 24 MHz operating speed supports responsive sequential control, while the 16 KB flash is suitable for a focused firmware image and configuration parameters. The 44-TQFP package is easy to inspect and assemble, although it occupies more board area than a leadless package. Designers should account for the external crystal or clock arrangement, programming access, supply decoupling, and any unused leads. Consumer-product validation should also check the temperature range and regulatory requirements, because those specifications are not established by the supplied distributor records.
Önerilen
Instrumentation and Signal Generation
The CY8C28533-24AXI is a plausible controller for compact instrumentation or programmable signal-generation products because the 24 MHz processor can sequence measurements, generate PWM-related signals, and manage I2C-connected converters or displays. The 16 KB flash capacity is adequate for a narrowly defined control application with concise firmware, while programmable mixed-signal resources provide a path to local analog functions. For laboratory-grade results, however, engineers must verify ADC resolution, noise, reference accuracy, bandwidth, and calibration limits directly from the manufacturer documentation. The component should not be treated as a precision converter based solely on its mixed-signal description. A conservative design uses supported analog pins, local reference distribution, and short traces between the MCU and sensitive measurement circuitry.
Önerilen
Communication-Assisted Embedded Modules
The CY8C28533-24AXI can coordinate a small embedded module that combines local I/O, PWM, and I2C communication with a higher-level processor or remote transceiver. For example, it could supervise a sensor node, generate an actuator waveform, and relay configuration data over I2C. The verified 8-bit M8C architecture and 24 MHz speed suit deterministic peripheral servicing, while 16 KB flash limits the firmware scope compared with larger microcontrollers. This makes the part attractive for focused satellite functions rather than protocol-heavy gateways. Design review should verify the available I2C pins, interrupt behavior, timer channels, and serial timing. Keep the MCU supply and ground layout isolated from noisy communication drivers where practical, and use the package pin data to route signals without conflicts.

Tasarım Notları
Do not assume that every CY8C28xxx device with a 44-TQFP package has identical lead assignments or peripheral resources. The verified records establish the 44-TQFP 10 x 10 mm package, 24 MHz CPU, and 16 KB flash for CY8C28533-24AXI, but they do not provide the complete pin table. Before schematic capture, compare power, ground, reset, clock, programming, I2C, PWM, and analog pins against the official package drawing. This also prevents an apparently close same-family replacement from creating a no-board-change substitution failure.
Follow the manufacturer power-decoupling and voltage-sequence requirements exactly. The supplied distributor records do not state the operating voltage range or quiescent current, so an engineer should not infer acceptable rails from the 24 MHz CPU rating. Place the required input and output capacitors next to their designated power leads, provide a low-impedance ground plane, and keep switching or motor-drive return currents away from sensitive analog and microcontroller traces. Confirm absolute maximum and recommended operating limits in the manufacturer datasheet before power-up.
Preserve the signal integrity of I2C, clock, and PWM paths by routing them away from motor-switching nodes and high-current return paths. The 44-TQFP footprint provides 44 leads, but lead density still requires careful assembly planning. Use a continuous ground reference beneath the device where the package design permits, avoid routing sensitive analog inputs alongside fast digital nets, and place external support components near their associated pins. PCB finish, solder mask, and copper geometry should be checked against assembly-house capability because the 10 x 10 mm TQFP has relatively fine lead pitch.
Uyumluluk Bilgisi
The supplied distributor records do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These values remain unknown rather than being inferred from the manufacturer or package.
