CY8C3245LTI-144 - 50MHz PSoC 3 MCU | Infineon
부품 번호: CY8C3245LTI-144 ✓ 활성CY8C3245LTI-144 개요
A PSoC 3 is a programmable embedded system-on-chip that combines a microcontroller core, memory, digital peripherals, analog peripherals, and programmable routing resources. This integration allows designers to implement application-specific control functions in a compact device instead of combining a separate microcontroller with multiple fixed-function analog and digital components. The 8051 CPU provides a familiar embedded-control architecture, while the PSoC peripheral architecture provides flexible resources for mixed-signal products.
Key features of the CY8C3245LTI-144 include a 50 MHz operating frequency, 32 KB of flash, 4 KB of SRAM, and 1 KB of EEPROM. The device also supports a DMA controller and programmable digital and analog peripherals. These features make it suitable for products requiring local signal acquisition, programmable control, data logging, communication, and compact user-interface handling without relying on a large external peripheral set.
The 50 MHz 8051 core provides faster instruction execution than standard low-speed 8-bit controllers while retaining the straightforward programming model associated with the 8051 ecosystem. The PSoC architecture adds configurable blocks that can be assigned to different signal-chain functions. This combination is particularly useful when product requirements are still evolving, because peripheral behavior can be adapted in firmware rather than requiring a hardware redesign for every input, output, timing, or analog-conditioning change.
Typical applications include industrial control panels, building automation, sensor-conditioning systems, instrumentation, consumer appliances, and compact embedded products. The 1.71 V to 5.5 V operating range supports integration into systems using modern low-voltage digital rails, although designers must observe the electrical limits associated with each supply rail, analog input, and I/O configuration.
A critical design step is to verify the exact package drawing and pin assignment for the ordering code before layout. Distributor records identify a 48-QFN package, while the manufacturer product page describes TQFP-144; use the package marked on the manufacturer ordering information and datasheet for the exact source and lot. Confirm pin multiplexing, exposed-pad requirements, decoupling, and clock configuration on the package drawing before fabrication.
This page combines manufacturer and distributor technical records, replacement guidance, application analysis, and practical design checks to support faster component evaluation. It highlights the configuration decisions that determine whether the PSoC 3 architecture, memory configuration, supply range, and package implementation fit a new embedded design.

일반적인 애플리케이션
CY8C3245LTI-144 적합 용도: 6 애플리케이션s: Industrial Sensor Conditioning, Building Automation Controller, Programmable Instrumentation, Smart Appliance Control, Data Logging and Edge Control, Connected IoT Sensor Node.
Industrial Sensor Conditioning
The CY8C3245LTI-144 fits industrial sensor-conditioning systems because its programmable analog and digital peripherals can process multiple external signals while the 50 MHz 8051 CPU handles configuration, filtering, and control decisions. The 32 KB flash provides room for application firmware, while 4 KB SRAM and 1 KB EEPROM support working state and retained parameters. A typical implementation routes sensor inputs through the configurable analog blocks, converts them through the PSoC ADC resources, and transfers results with DMA. This reduces external conditioning hardware, although the exact analog ranges, accuracy, noise, and sampling performance must be confirmed for each configured peripheral.
추천
Building Automation Controller
The CY8C3245LTI-144 is suitable for a building automation controller that must manage digital I/O, analog sensor inputs, timing functions, and communication-related logic. Its 50 MHz 8051 core provides deterministic instruction throughput, and the programmable PSoC peripherals allow functions such as input capture, output compare, and signal generation to be tailored to the system. With 32 KB flash, 4 KB SRAM, and 1 KB EEPROM, the device can combine control firmware with local configuration storage. Designers should still validate low-power behavior, peripheral timing, and the package-specific pin allocation before deploying it in a connected building-control product.
추천
Programmable Instrumentation
The CY8C3245LTI-144 works well in programmable instrumentation where analog measurement and digital control must share one microcontroller platform. Its configurable analog peripherals can support signal conditioning and conversion, while programmable digital blocks can handle capture, timing, or output functions without a fixed peripheral set. The 50 MHz 8051 core also allows the firmware to combine acquisition with local calculations and interface management. For laboratory or process equipment, validate accuracy, noise, temperature behavior, grounding, and calibration strategy against the final operating range; the core architecture alone does not establish metrology performance.
추천
Smart Appliance Control
The CY8C3245LTI-144 is appropriate for smart appliances that combine motor or user-interface control with programmable input conditioning. Its 50 MHz 8051 core has sufficient throughput for supervisory logic, while the PSoC architecture can place digital timing and analog functions close to the application. Memory resources include 32 KB flash for control code, 4 KB SRAM for active state, and 1 KB EEPROM for configuration values. A practical design should define peripheral assignments in firmware, isolate noisy switching paths, and confirm that the selected package exposes all required pins for the appliance’s sensors, communications, and power controls.
추천
Data Logging and Edge Control
The CY8C3245LTI-144 can serve as the central controller in a compact edge-data system that acquires sensor information, performs local decisions, and records operating state. The 50 MHz 8051 processor handles protocol framing and control logic, while DMA reduces the processor burden when transferring data between configurable peripherals and SRAM. Its 1.71 V to 5.5 V operating range supports integration into embedded power architectures, and EEPROM can retain calibration or configuration values. Designers must size firmware and RAM for the logging workload, avoid blocking memory operations during acquisition, and verify the package pins required for storage and external interfaces.
추천
Connected IoT Sensor Node
The CY8C3245LTI-144 fits a connected sensor node that needs local sensing, programmable signal conditioning, and compact control logic. The PSoC 3 architecture combines an 8051 core with configurable analog and digital peripherals, allowing designers to implement functions according to the selected sensor interface rather than relying on a fixed signal chain. Its 32 KB flash supports protocol and application firmware, while 4 KB SRAM accommodates active working buffers. In low-power IoT products, verify sleep behavior, wake sources, pin retention, and analog-state requirements in the manufacturer documentation because these functions depend on the programmed peripheral configuration.

설계 노트
Resolve the package before committing the footprint. Distributor records identify 48-QFN (7 mm x 7 mm), while the manufacturer product page describes TQFP-144 for the displayed ordering code. Download the exact ordering information and package drawing, then verify pin 1, exposed-pad requirements if applicable, land pattern, and solder mask. Do not combine a footprint from one package description with pin data from another.
Decouple each applicable supply rail directly at its package pins and follow the manufacturer’s recommended capacitance and voltage requirements. The device supports a 1.71 V to 5.5 V operating range, but individual core, analog, and I/O supplies may have narrower limits or sequencing rules. Verify every rail in the pin-description table and avoid allowing unused analog supplies to float. Keep high-current return paths away from sensitive analog grounding points.
Program the PSoC routing deliberately. Place external analog components near their assigned pins, keep sensitive traces short, and separate clocks, sensor inputs, and communication lines from switching-node current. The DMA controller can improve data-transfer efficiency, but correct performance still depends on assigning peripherals and buffers without contention. Validate timing and signal integrity across the intended clock, sensor, and I/O conditions before production.
Do not treat similar memory size or CPU frequency as proof of drop-in compatibility. A valid substitute must match the package, pin functions, supply requirements, peripheral assignments, programming model, memory map, and application expectations. The only identified related ordering code is CY8C3245LTI-144T; use its suffix-specific documentation to determine whether it meets the mechanical and procurement requirements of the target design.
