N.º da peça: CY8C5368LTI-026 ✓ AtivoCY8C5368LTI-026 Visão geral
A programmable system-on-chip, or PSoC, is a semiconductor platform that integrates a microcontroller with configurable analog and digital functional blocks. Its place in the product hierarchy is microcontroller → programmable system-on-chip → embedded processor → semiconductor. Compared with a conventional microcontroller that relies mainly on fixed peripherals, a PSoC allows designers to adapt selected input, output, analog, and digital functions to the target application. This flexibility can reduce external component requirements and support compact control-system designs.
The CY8C5368LTI-026 combines a 67 MHz maximum operating frequency with 256 KB of embedded flash and 64 KB of SRAM. Its 32-bit Cortex-M3 architecture provides the processing foundation for control logic, state-machine handling, communications, and supervisory functions. The 68-QFN surface-mount package supports dense PCB layouts, while its exposed-pad construction provides a thermal path from the device to the board. Exact pin assignments, programmable-function details, clock limits, and electrical operating limits should be taken from the manufacturer datasheet and pin-description tables.
The CY8C53 family combines conventional microcontroller functions with programmable analog and digital blocks. This architecture is useful when a design requires adaptable signal conditioning, control interfaces, or timing behavior rather than several unrelated fixed peripherals. Firmware and development-tool support determine how those resources are assigned. Engineers should review the relevant PSoC Creator device configuration, peripheral documentation, and electrical recommendations before finalizing clocks, analog ranges, pin multiplexing, and power sequencing.
Typical applications include industrial monitoring and control, connected sensor nodes, programmable signal-conditioning systems, building automation equipment, consumer interfaces, and embedded control platforms. The 67 MHz Cortex-M3 core is suitable for coordinating multiple software tasks, while the PSoC resources can reduce the need for separate analog and digital interface devices. The 256 KB flash capacity provides room for application firmware, and the 64 KB SRAM supports working memory, buffers, and real-time control state.
PCB implementation should preserve the package thermal pad connectivity, route sensitive analog inputs away from fast-switching nodes, and follow the manufacturer’s decoupling and exposed-pad recommendations. Validate the selected configuration for clock frequency, operating voltage, peripheral limits, startup behavior, and environmental requirements. Migration or replacement decisions must be based on package pin mapping and device configuration rather than processor family or memory size alone.
This page consolidates the manufacturer-part identity, memory and package characteristics, replacement considerations, comparison parameters, and practical design guidance into one engineering-focused reference. It distinguishes confirmed device attributes from parameters that require validation, helping designers evaluate PCB reuse, firmware portability, supply-chain continuity, and application suitability more efficiently.

Aplicações típicas
CY8C5368LTI-026 é adequado para 6 aplicaçãos: Industrial Monitoring and Control, Connected Sensor Node, Programmable Signal Conditioning, Building Automation Controller, Consumer Interface Controller, Programmable Control Platform.
Industrial Monitoring and Control
The CY8C5368LTI-026 fits industrial monitoring equipment that needs to acquire sensor information, apply configurable signal conditioning, and execute real-time control logic on one microcontroller platform. Its ARM Cortex-M3 core operates up to 67 MHz, providing enough processing headroom for state machines, communication handling, diagnostics, and supervisory functions. The 256 KB of flash supports application code and configuration storage, while 64 KB of SRAM accommodates working buffers and real-time state. PSoC programmable resources can reduce the number of separate interface components when their electrical limits match the industrial design. The selected operating-voltage range, temperature grade, isolation method, and analog-input limits must be verified before deployment.
Connected Sensor Node
The CY8C5368LTI-026 is suitable for a connected sensor node that must process local measurements before forwarding results through a serial or network interface. Its 67 MHz Cortex-M3 core supports protocol processing, data conditioning, and event handling, while 256 KB of flash provides room for firmware, calibration data, and communication code. The 64 KB of SRAM can hold sample buffers and protocol state. PSoC configurability is particularly useful when analog front-end functions and digital routing must be adapted to different sensors. Before assigning communication pins, confirm that the required UART, SPI, CAN, USB, or other interface is present in the device configuration and remains valid at the intended voltage and frequency.
Programmable Signal Conditioning
The CY8C5368LTI-026 can serve as the controller for programmable analog and digital signal-conditioning stages because it combines a Cortex-M3 processor with configurable PSoC resources. The processor handles calibration, range selection, filtering decisions, fault detection, and communications, while the programmable blocks implement signal paths close to the sensor or source. Its 67 MHz operating capability supports deterministic control and measurement sequences, and its 256 KB of flash leaves room for calibration tables and application logic. Exact ADC, DAC, comparator, amplifier, routing, and sampling characteristics must be taken from the manufacturer datasheet rather than inferred from the product family name.
Building Automation Controller
The CY8C5368LTI-026 is appropriate for building-automation equipment that coordinates sensors, relays, user interfaces, and communications within a single embedded controller. Its 32-bit Cortex-M3 architecture can manage multiple control tasks, while 256 KB of flash and 64 KB of SRAM provide useful memory headroom for protocol stacks and application logic. Configurable digital and analog resources can simplify adaptation between different building systems and field-configurable products. A production design must still account for the required operating-temperature range, supply interruptions, relay transients, safety margins, and communication-interface availability. Firmware should include recovery behavior and validated device configuration for each supported building subsystem.
Consumer Interface Controller
The CY8C5368LTI-026 can implement a configurable consumer interface that combines touch or control inputs, indicator outputs, communications, and application logic. Its PSoC architecture allows selected digital routing and analog functions to be adapted while the Cortex-M3 core executes user-interface logic, debounce processing, state management, and data exchange. The 67 MHz clock supports responsive control, and the memory capacities are suitable for moderate embedded applications. Actual touch performance depends on the selected analog block and front end, so input range, resolution, acquisition time, and noise performance must be confirmed in the datasheet. The 8 mm by 8 mm QFN package also requires careful exposed-pad and thermal design.
Programmable Control Platform
The CY8C5368LTI-026 works well as a reusable embedded control platform for prototypes and production products requiring adaptable peripherals rather than a fixed pin arrangement. Its 67 MHz ARM Cortex-M3 core executes control algorithms, the 256 KB flash stores application and configuration data, and the 64 KB SRAM supports runtime working memory. PSoC programmable resources can consolidate functions such as timers, serial interfaces, analog paths, and routing into one device, reducing board complexity when properly configured. Development should include a complete pin-assignment review, timing analysis, peripheral resource allocation, and power-state tests. Firmware migration is easiest when another 68-QFN member has the same memory organization and peripheral compatibility.

- Exact manufacturing identity preserves the target's resource configuration (vs CY8C5368LTI-026T)
Notas de projeto
Design the 68-QFN footprint directly from the manufacturer package drawing. Preserve the exposed-pad connection, verify pin-one orientation, and follow the specified solder-mask and land-pattern guidance. Place input and output decoupling capacitors close to their associated pins, provide a low-impedance ground plane, and route high-current or fast-switching nodes away from sensitive analog inputs. The generic package image should not be used to create solder stencils or PCB artwork.
Use the exposed thermal pad as part of the thermal design rather than treating it as an unused electrical land. Connect it to the ground plane through the package-specific via arrangement and maintain adequate copper area on both sides of the PCB where the board construction permits. Validate the final junction temperature at the highest expected clock rate, peripheral loading, ambient temperature, and supply voltage. Package thermal characteristics should be taken from the manufacturer documentation and adapted to the actual board stack-up.
Do not treat a shared QFN outline as proof of drop-in compatibility. The identified CY8C5365LTI-104 comparison part has only 32 KB of flash versus 256 KB in the CY8C5368LTI-026, so firmware footprint, initialization code, pin functions, and peripheral assignments may differ. Review the complete device configuration and pin tables before any substitution. Likewise, distinguish the target ordering code from the -026T tape-and-reel shipping form when creating procurement records or assembly BOMs.
Separate analog, digital, and clock-sensitive routes as far as practical. Keep sensor inputs short, place analog grounding components near their pins, and avoid routing them beneath or alongside high-speed digital nets. PSoC signal routing is configurable, but electrical performance still depends on correct pin assignment, impedance assumptions, and the device's routing rules. Validate final configurations with the manufacturer design tools and test the assembled board across voltage, temperature, and intended clock conditions.
