Teilenummer: CY8C3245PVI-134 ✓ AktivCY8C3245PVI-134 Übersicht
A PSoC 3 microcontroller is a programmable embedded system-on-chip that integrates a microcontroller core, configurable analog and digital peripherals, memory, and interrupt resources. Its position in the embedded hierarchy is MCU → programmable system-on-chip → semiconductor. This integration allows designers to implement application-specific functions without relying on a large collection of discrete input and output components.
The CY8C3245PVI-134 provides 32 KB of Flash program memory and 4 KB of SRAM in an 8-bit, 8051-compatible architecture. Its clock can operate up to 50 MHz, while the dual datapointer feature supports efficient data movement. The device also includes 1 KB of data EEPROM, 8 KB of ECC Flash, and programmable analog and digital peripheral resources.
The device provides an interrupt system with 27 sources and eight priority levels. Its Peripheral Hub Unit includes eight parallel access paths for connected peripherals, supporting efficient data exchange within the programmable embedded architecture. These resources make the MCU suitable for designs requiring both control logic and configurable interface functions.
The CY8C3245PVI-134 is particularly suited to touch interfaces and LCD controllers because it combines an 8051 core, programmable peripherals, EEPROM, and Flash in one package. The same integration can serve compact human-machine interfaces, embedded control panels, sensor-conditioning systems, and low-power peripheral controllers.
Designers should verify the complete pin configuration, clock requirements, programming method, and peripheral assignments in the Infineon Technologies datasheet before laying out a 48-SSOP PCB. Operating-voltage compatibility with external components is especially important because the supported 1.71 V to 5.5 V range can span multiple electronic systems.
This product overview consolidates the device identity, operating limits, memory configuration, embedded peripherals, package information, design considerations, and source links needed for initial component selection. It also distinguishes confirmed characteristics from details that require direct review of the manufacturer documentation.

Typische Anwendungen
CY8C3245PVI-134 ist geeignet für 6 Anwendungs: Capacitive Touch User Interfaces, LCD Control and Human-Machine Interfaces, Embedded Sensor Signal Conditioning, Industrial Control Panels, Low-Voltage Embedded Accessories, Medical and Diagnostic Interfaces.
Capacitive Touch User Interfaces
The CY8C3245PVI-134 fits capacitive touch controls because its programmable analog and digital peripherals can be combined with a 50 MHz 8051 core and 32 KB of Flash in one 48-SSOP package. Use the device to scan touch inputs, apply filtering, maintain interface state, and report user actions without requiring a separate processor for basic sensing functions. The 4 KB SRAM supports working buffers for sampled data, while 1 KB of EEPROM can retain configuration parameters. Confirm the required touch-sensing block, scan timing, pin assignments, and calibration method against the manufacturer peripheral documentation before finalizing the PCB and firmware.
LCD Control and Human-Machine Interfaces
The CY8C3245PVI-134 can serve as the local controller for an LCD-based human-machine interface when designers want programmable peripherals and control logic in a compact package. Its 50 MHz 8051 core provides timing headroom for display updates and interface handling, while 32 KB Flash stores application code and 4 KB SRAM holds frame or command data. The 1.71 V to 5.5 V operating range also supports integration with multiple embedded voltage domains. Select and route the appropriate LCD interface pins, verify timing requirements, and account for display-bus loading before approving the design.
Embedded Sensor Signal Conditioning
The CY8C3245PVI-134 is appropriate for compact sensor-conditioning and data-processing modules because programmable analog and digital peripherals can be configured alongside an 8-bit 8051 core. The device can acquire inputs, execute control logic, and manage sensor-related data within a single 48-SSOP device. Its 32 KB Flash supports embedded application programs, and 4 KB SRAM can accommodate measurement buffers and protocol state. The practical benefit is reduced component count and board area, although the selected analog resources, interrupt latency, signal range, and precision must be validated for the target sensor and operating conditions.
Industrial Control Panels
The CY8C3245PVI-134 fits industrial control-panel electronics that combine local controls, status display, and configurable I/O in a small embedded system. A 50 MHz 8051 core can coordinate panel events, while 32 KB Flash, 4 KB SRAM, 1 KB EEPROM, and 8 KB ECC Flash provide local code and data resources. Programmable analog and digital peripherals reduce the need for separate interface devices. For an industrial deployment, verify the operating-temperature grade, isolation boundaries, ESD requirements, update method, and long-term supply plan against the exact manufacturer ordering information before production release.
Low-Voltage Embedded Accessories
The CY8C3245PVI-134 is useful in low-voltage embedded accessories where an 8-bit controller can handle local I/O, communication, and configuration functions without a higher-complexity processor. Its operation from 1.71 V to 5.5 V supports integration near 1.8 V, 2.5 V, 3.3 V, or 5 V system rails, subject to the requirements of the selected peripherals. The 48-SSOP package can also simplify compact, high-density layouts. Designers should confirm internal clock behavior, required external components, I/O levels, and programming voltage before finalizing the accessory architecture.
Medical and Diagnostic Interfaces
The CY8C3245PVI-134 can support low-level medical or diagnostic interface modules that require local control, programmable signal handling, and persistent configuration data. Its 50 MHz 8051 core can execute deterministic control tasks, while the 32 KB Flash, 4 KB SRAM, 1 KB EEPROM, and 8 KB ECC Flash provide integrated firmware resources. The 1.71 V to 5.5 V range allows flexible integration into isolated low-voltage subsystems. Because the device is not identified as an AEC-Q100 automotive or medical-qualified part in the product information, confirm the applicable quality, electrical-safety, and regulatory requirements separately before using it in patient-connected equipment.

Wichtigste Unterscheidungsmerkmale
- Higher memory density than the identified CY8C3444 comparison (vs. CY8C3444PVI-100)
- 8051-compatible control architecture (vs. CY8C3444PVI-100)
- Configurable system integration (vs. CY8C3245PVI-167)
Designhinweise
Assign the 48-SSOP pins directly from the Infineon Technologies pin-description table before routing the PCB. The PSoC architecture can offer multiple peripheral functions on many pads, so reserve the required programming pins and confirm that each selected analog or digital peripheral is available on the chosen package. Keep sensitive analog inputs away from fast-switching digital routes, and provide short return paths to the device ground pins.
Design the supply network for the full 1.71 V to 5.5 V operating range and place the required bypass capacitors close to the corresponding power pins. Check each peripheral's permitted voltage range because core voltage, analog supplies, and external interface levels can have different limits. Use the manufacturer recommended capacitor values and stability configuration rather than substituting generic values that may alter startup behavior, noise performance, or peripheral operation.
Do not assume that a device with the same 48-SSOP package is a drop-in replacement. The CY8C3245PVI-167 comparison includes ordering differences, the CY8C3245PVI-134T is a tape-and-reel ordering form, and the CY8C3444PVI-100 has 16 KB rather than 32 KB of Flash. Validate the exact suffix, memory map, core behavior, peripheral resources, pin assignments, and programming configuration before changing the released MPN.
Compliance-Informationen
The exact-ordering-configuration compliance declarations should be checked in the Infineon Technologies product documentation. No AEC-Q100 automotive qualification is identified for this MPN.
