CY8C5367LTI-003 - 32-Bit Cortex-M3 PSoC 5 MCU | Infineon
MPN： CY8C5367LTI-003 ✓ 啟用中CY8C5367LTI-003 概覽
A PSoC, or programmable system-on-chip, is a microcontroller architecture that integrates a CPU with configurable analog and digital blocks on one device. The PSoC 5 family is positioned within the broader embedded-control hierarchy as a programmable microcontroller, system-on-chip, and power-management-oriented embedded controller. Instead of relying only on fixed peripherals, suitable designs can use configurable blocks for functions such as digital logic, analog conversion, timers, communication, and signal conditioning. This reduces the need for separate external components when the application can be mapped onto the available programmable resources.
The CY8C5367LTI-003 is identified as part of the CY8C53 PSoC 5 family and includes an ARM Cortex-M3 processor core with a maximum listed speed of 67 MHz. Its 128 KB flash is organized as 128K x 8, and the device provides 32K x 8 RAM. The 36 available I/O pins provide connections for sensors, displays, communication interfaces, control outputs, and external peripheral control. The industrial temperature designation and no-lead surface-mount format are suitable for compact embedded equipment requiring a permanent-board installation.
Typical applications include industrial sensor controllers, building and automation equipment, motor and actuator control interfaces, communication equipment, consumer peripherals, and compact embedded instruments. The programmable peripheral architecture can consolidate functions that would otherwise require separate analog, digital, and timing ICs. The 67 MHz Cortex-M3 core and 128 KB flash also make the device appropriate for protocol handling, supervisory logic, data acquisition, and control systems requiring deterministic peripheral configuration.
Design decisions should account for the exposed-pad thermal path, PCB copper area, operating-temperature limits, and the exact pin assignment of the selected package. Use the manufacturer datasheet for pin descriptions, power sequencing, decoupling recommendations, clocking, programming, and peripheral resource details. The 68-pin package is not represented by a dedicated standard package-diagram key in the available package library, so the generic package illustration should be used together with the manufacturer pinout documentation.
This product page combines the core device identity, package information, technical specifications, design considerations, and a structured comparison with related CY8C53-family devices. It is intended to support component selection, board-layout planning, firmware preparation, and procurement review without replacing the manufacturer datasheet for final design sign-off.

典型應用
CY8C5367LTI-003 適用於 6 應用s: Industrial Sensor and Condition Monitoring, Building Automation Controller, Motor and Actuator Control, Communication Equipment and Protocol Bridge, Compact Embedded Instrument, Data Acquisition and Control Module.
Industrial Sensor and Condition Monitoring
The CY8C5367LTI-003 fits industrial sensing designs that require real-time signal acquisition, local filtering, status reporting, and control logic in one compact controller. Its ARM Cortex-M3 core operates up to 67 MHz, providing enough processing performance for sensor fusion and communication tasks, while the PSoC 5 programmable architecture can consolidate configurable analog and digital functions. The 128 KB flash accommodates firmware, configuration data, and field-upgrade logic, while 32 KB RAM supports buffers and working variables. With 36 I/O pins and an industrial temperature grade, the device can interface sensors, status indicators, communications, and alarms while reducing the number of discrete components in a compact control board.
推薦
Building Automation Controller
A building-automation controller must supervise many digital inputs, maintain deterministic timing, and coordinate outputs across lighting, access, HVAC, or occupancy equipment. The CY8C5367LTI-003 provides a 67 MHz 32-bit Cortex-M3 core for protocol handling and supervisory logic, 128 KB flash for application firmware, and 32 KB RAM for message and state buffers. Its 36 I/O pins can support sensors, switches, relays, and interface circuits, while configurable PSoC blocks can offload timing and digital functions. The 8 mm by 8 mm 68-QFN package also supports compact controller boards where connector density and long product life matter.
推薦
Motor and Actuator Control
The CY8C5367LTI-003 can serve as the supervisory controller in actuator and small-motor systems where position sensing, timing, fault handling, and communication must be coordinated. The 67 MHz Cortex-M3 core can execute motion-state logic and diagnostic routines, while configurable PSoC timers and digital blocks can support precise event handling. Its 36 I/O pins provide connections to encoders, limit sensors, driver-control signals, and status indicators. Designers should pair the MCU with an appropriate transistor or motor-driver stage and verify current limits, protection timing, grounding, and thermal performance separately because the microcontroller itself is not the power stage.
推薦
Communication Equipment and Protocol Bridge
The CY8C5367LTI-003 is appropriate for embedded protocol converters and communication controllers that need deterministic timing alongside configurable peripheral support. The 32-bit Cortex-M3 core at up to 67 MHz can handle framing, checksums, buffering, and protocol conversion, while 128 KB flash and 32 KB RAM provide room for firmware and message storage. The 36 I/O pins can support UART, SPI, I2C, or discrete control signals when the corresponding PSoC resources are configured appropriately. For field equipment, add the appropriate isolation, surge protection, and transceiver components, and validate timing margins against the highest supported bus rate.
推薦
Compact Embedded Instrument
The CY8C5367LTI-003 can serve as the control platform for compact instruments that combine a local display, keypad, sensor interface, and communications port. Its 67 MHz processor supports responsive measurement control and menu logic, while 128 KB flash accommodates application code and 32 KB RAM supports sampled-data and display buffers. The 36 I/O pins provide enough connectivity for display control, buttons, status LEDs, and external interface signals. The PSoC programmable blocks can also reduce the need for separate logic, timing, or analog-support ICs, provided the selected peripheral configuration is validated for the required measurement accuracy and latency.
推薦
Data Acquisition and Control Module
For data-acquisition and control modules, the CY8C5367LTI-003 combines a 67 MHz 32-bit processing core with programmable analog and digital resources in a single device. The 128 KB flash can store acquisition firmware, calibration tables, and configuration, while 32 KB RAM supports sample buffering and working state. With 36 I/O pins, the controller can operate multiple sensor channels, trigger inputs, status outputs, and communications links. The PSoC architecture is particularly useful when repeatable timing and configurable signal paths are needed, although front-end protection, reference accuracy, channel multiplexing, and input bandwidth should be designed around the manufacturer’s peripheral limits.

設計說明
Treat the exposed pad as part of the thermal and electrical design. Place the device on a multilayer PCB with a continuous ground or supply plane beneath the pad, use the manufacturer land pattern, and minimize thermal vias directly beneath fine-pitch pins. Estimate junction temperature from actual power loss and the effective board thermal resistance, then apply the manufacturer maximum junction and ambient limits. The 8 mm by 8 mm QFN footprint can conduct heat effectively only when the pad, vias, and copper area are designed as one thermal system.
Follow the manufacturer PCB layout and decoupling guidance exactly, especially for supply pins, analog references, clock inputs, and exposed-pad connections. Keep high-current return paths away from sensitive analog traces, provide a quiet ground reference, and route communications and switching interfaces away from precision signal paths. Validate the final layer stack, via placement, and copper geometry with the manufacturer’s land-pattern and thermal recommendations before fabrication.
Do not assume that every CY8C53-family device is software- and pin-compatible. Before substituting another family member, verify the ordering suffix, package dimensions, exposed-pad connection, supply pins, debug interface, clock requirements, peripheral resource map, memory sizes, and temperature grade. Also distinguish the original device from CY8C5367LTI-003T because the final suffix can identify a different orderable packaging or delivery form even when the base MPN is identical.
Plan the power tree around the manufacturer’s recommended operating ranges and startup behavior. The MCU may require multiple internal rails even though the package exposes a single device identifier, and peripherals can create additional current demand during operation. Use local decoupling at each applicable supply pin, preserve clean power sequencing, and measure startup and shutdown behavior across the intended voltage range. The exposed pad must follow the manufacturer’s electrical connection guidance rather than being treated as an optional thermal feature.
合規資訊
The device is described as industrial grade, but no explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statement appears in the manufacturer-linked datasheet listing. AEC-Q100 is marked not applicable because this is an industrial microcontroller rather than an automotive-qualified device.
