부품 번호: CY8C5466LTI-063 ✓ 활성CY8C5466LTI-063 개요
A programmable system-on-chip is a semiconductor category that places a microcontroller core, programmable logic, analog peripherals, and memory on one silicon device. The PSoC architecture lets designers implement application-specific functions in configurable digital and analog blocks rather than relying only on fixed hardware peripherals. Within the broader semiconductor hierarchy, this device is an embedded microcontroller and mixed-signal system-on-chip for industrial control applications.
The CY8C5466 family operates at up to 67 MHz and provides 64KB of Flash plus 16K x 8 RAM for firmware, working memory, configuration data, and control routines. Its 36 I/O pins support digital interfaces and programmable signal-processing resources. The device uses an internal oscillator, reducing the need for an external clock source in designs that do not require a more precise external reference.
The 68-VFQFN package is specified as an 8 x 8 mm square, no-lead industrial-temperature device with an exposed pad. The exposed thermal pad improves heat transfer from the die into the PCB copper, which is important when the integrated analog, digital, and processing resources operate continuously. The exposed pad still requires careful PCB layout and a thermal strategy based on actual activity and ambient temperature.
Typical applications include industrial monitoring, sensor acquisition, programmable signal conditioning, motor and process-control interfaces, embedded data acquisition, and compact control systems. The PSoC architecture can consolidate functions such as control logic, analog measurement, and communications peripheral support into one microcontroller-based design, reducing board-level component count when firmware and analog configuration are properly designed.
For a new layout, follow the manufacturer pin-assignment and land-pattern guidance, connect the exposed pad to the appropriate ground or thermal plane, and place decoupling capacitors close to the supply pins. Validate the configured clock, analog ranges, unused pins, bootloader, and power sequencing in the final firmware. Treat the 67 MHz maximum as a device capability rather than a requirement for every design.
This product record combines exact device characteristics with application guidance, parameter comparisons, package considerations, and strict same-footprint alternatives. It is intended to help engineers identify the correct memory configuration, package, temperature grade, and replacement strategy before committing a CY8C5466LTI-063 design to production.

Industrial Sensor Acquisition
The CY8C5466LTI-063 fits industrial sensor-acquisition systems that combine signal conditioning, control logic, and data handling in one device. Its ARM Cortex-M3 core operates up to 67 MHz, providing enough performance for sequencing measurements and applying calibration while 64KB of Flash stores firmware and configuration data. The 16K x 8 RAM supports buffers, acquisition state, and communication routines. Its 36 I/O pins simplify connections to sensors and digital interfaces, while the programmable analog and digital blocks can implement application-specific measurement functions without relying on a large external logic device.
추천
Programmable Signal Conditioning
The CY8C5466LTI-063 is suitable for programmable signal-conditioning front ends where analog measurement and digital processing must be coordinated. The PSoC architecture combines configurable analog resources, programmable digital blocks, and a 67 MHz ARM Cortex-M3 processor in one 8 x 8 mm device. Its 64KB Flash accommodates lookup tables, conversion routines, and calibration coefficients, while 16K x 8 RAM can hold sampled data and intermediate calculations. The 36 I/O pins allow sensor inputs, control outputs, and status signaling to be consolidated without placing every filtering function in external fixed-function components.
추천
Embedded Data Acquisition
The CY8C5466LTI-063 supports compact embedded data-acquisition equipment that must sample inputs, process records, and communicate results. The 67 MHz ARM Cortex-M3 core can manage interrupts and real-time acquisition tasks, while 64KB of Flash provides space for application firmware and 16K x 8 RAM accommodates working buffers. With 36 I/O pins, the device can serve multiplexed analog and digital inputs without relying on a large pin-count MCU. The exposed-pad 68-VFQFN package also supports compact board construction, although thermal analysis is essential when analog and digital blocks operate at high utilization.
추천
Process Control Interfaces
The CY8C5466LTI-063 is appropriate for distributed process-control interfaces that must translate sensor and operator inputs into actuator commands. Its 67 MHz ARM Cortex-M3 processor supports deterministic control loops, and its 36 I/O pins can be configured for digital I/O, timers, communication functions, and programmable peripheral activity. The PSoC architecture allows control logic and analog functions to share one device, reducing board complexity when the application does not require large external memory. Firmware must reserve sufficient Flash and RAM for diagnostics, while the PCB must provide the manufacturer's recommended exposed-pad land pattern and low-impedance supply distribution.
추천
Motor and Automation Control
The CY8C5466LTI-063 can serve as the control engine in compact automation and motor-interface modules where programmable timing, analog monitoring, and communications must coexist. Its 67 MHz ARM Cortex-M3 core can execute motion-control or supervisory logic, while the PSoC digital blocks and analog resources can offload dedicated functions from the CPU. The 64KB Flash and 16K x 8 RAM are suitable for moderate control firmware and state handling. Engineers should confirm timer routing, analog limits, motor-drive timing, and fault-response behavior in the device configuration, and use the exposed pad for effective thermal transfer.
추천
Low-Power Monitoring Node
The CY8C5466LTI-063 fits monitoring nodes that acquire local sensor information, execute threshold logic, and report system status. Its internal oscillator eliminates an external clock component in designs that tolerate internal timing accuracy, and the 64KB Flash supports protocol handlers and local configuration. SixteenK x 8 of RAM provides state and communication buffers, while 36 I/O pins simplify peripheral attachment. Designers should use the PSoC power-management controls to place unused blocks into low-power states, verify sleep and wake behavior, and size the exposed-pad copper area around the actual duty cycle rather than maximum clock performance.

설계 노트
Treat the exposed pad as a mandatory thermal and electrical-design feature rather than an optional copper feature. Follow the manufacturer land pattern, provide a low-impedance connection to the designated pad plane, and use thermal vias only where they do not interfere with the recommended layout. The available records do not state a thermal resistance, so junction temperature and copper-area requirements must be calculated from manufacturer limits and measured board performance before production release.
Place decoupling capacitors close to the associated supply and ground pins, with each loop kept as small as practical. Route high-current return paths into the ground or pad plane without splitting the plane beneath the device. Because the part combines high-frequency digital processing with programmable analog resources, supply distribution and return-current continuity are essential for predictable analog behavior as well as CPU performance.
Assign analog-sensitive nets away from switching-clock and high-current paths, and keep sensor inputs short and guarded against nearby digital activity. Check each peripheral's alternate routing and available pin resources before finalizing the schematic. The 36 I/O count should not be treated as permission to ignore pin-multiplexing constraints; verify the exact signal-to-pin mapping in the manufacturer pin table and device configuration.
Do not assume that the non-T and T orderings are interchangeable for the receiving operation: one is listed in tray packaging and the other uses a different shipping suffix. Also avoid changing the CY8C546x suffix solely to obtain more Flash without reviewing linker settings, boot code, programming configuration, qualification records, and the complete electrical specification. Perform a firmware and hardware regression check for every approved alternative.
