CY8C5468LTI-037 - 67MHz PSoC 5 Cortex-M3 MCU | Infineon
MPN: CY8C5468LTI-037 ✓ AktifCY8C5468LTI-037 Ringkasan
A programmable system-on-chip, or PSoC, is a mixed-signal microcontroller architecture that integrates a CPU with configurable digital and analog peripherals. The PSoC 5 family belongs to the broader microcontroller hierarchy and can replace combinations of separate microcontroller, interface, converter, and signal-conditioning devices when a suitable fixed-function peripheral is not required.
The CY8C5468LTI-037 provides 256 KB of flash for firmware and 32-bit processing at up to 67 MHz. Its 68-QFN package supports compact, high-density PCB layouts, while the no-lead construction is intended for surface-mount assembly. The industrial temperature-grade marking identifies its intended operating class, although the exact minimum and maximum temperatures should be confirmed in the manufacturer datasheet before defining the product's environmental limits.
The device is based on the ARM Cortex-M3 core and includes the standard architectural facilities described for the PSoC 5 family, including a Flash Patch and Breakpoint block, Data Watchpoint and Trace, and Instrumentation Trace Macrocell support. These debug and trace facilities allow engineers to inspect execution, capture data, and diagnose firmware behavior with compatible debug hardware and development software.
Typical uses include industrial control modules, connected sensor equipment, compact user interfaces, communications gateways, and embedded measurement systems. The combination of 67 MHz processing, 256 KB of program storage, and a space-efficient 68-QFN package is especially useful when an application needs substantial control performance without the footprint of a larger microcontroller package.
PCB planning should reserve the exact 68-QFN land pattern, confirm exposed-pad requirements, and follow the manufacturer's assembly and decoupling guidance. Firmware migration should also account for the resource changes between PSoC 5 and PSoC 5LP devices, particularly for designs adopting the manufacturer-designated equivalent CY8C5668LTI-LP014.
This page combines the verified device specifications, manufacturer-designated migration paths, package details, and practical selection considerations to help engineers evaluate replacements without overlooking peripheral, memory, firmware, or PCB-compatibility differences.

Aplikasi Biasa
CY8C5468LTI-037 patut untuk 6 aplikasis: Industrial Control Module, Connected Sensor Equipment, Compact Communications Gateway, Embedded Measurement System, Human-Machine Interface Controller, Programmable Embedded Platform.
Industrial Control Module
The CY8C5468LTI-037 fits compact industrial control modules that require deterministic control and programmable peripheral integration. Its 32-bit ARM Cortex-M3 core operates up to 67 MHz, while 256 KB of flash accommodates control firmware, state logic, and communication routines. The 68-QFN 8 x 8 mm package keeps the controller footprint compact, but designers should reserve the exact land pattern and follow the manufacturer's decoupling and exposed-pad guidance. Firmware should include watchdog, brownout, and fault-handling paths because embedded control systems must continue operating safely when sensors, actuators, or communication links fail.

Connected Sensor Equipment
The CY8C5468LTI-037 is suitable for connected sensor equipment that must sample, process, and communicate local data without relying on a host processor. Its 67 MHz Cortex-M3 performance provides more than enough instruction throughput for digital filtering, protocol handling, and supervisory logic, while 256 KB of flash supports a complete embedded application. The 68-QFN package allows the controller to sit close to sensors and signal-conditioning circuitry. Designers should partition analog and digital pathways carefully, validate grounding and reference arrangements against the datasheet, and confirm that the selected PSoC peripherals satisfy the required sensor bandwidth.

Compact Communications Gateway
The CY8C5468LTI-037 can serve as the host controller in a compact communications gateway or protocol-conversion device. Its 32-bit Cortex-M3 core operating at 67 MHz can manage multiple packet-processing tasks, while the PSoC 5 family's programmable resources allow digital interfaces to be consolidated around the MCU. The 256 KB of flash provides room for a protocol stack and configuration tables, and the 68-QFN package preserves routing space on dense boards. Confirm interrupt latency, available peripheral assignments, and timing requirements against the device documentation before selecting it for high-throughput networking.

Embedded Measurement System
The CY8C5468LTI-037 is appropriate for embedded measurement systems that combine acquisition control, signal processing, calibration, and local data handling. A 67 MHz ARM Cortex-M3 core supports responsive digital filtering and control, while 256 KB of flash can hold measurement algorithms and configuration information. Its 68-QFN 8 x 8 mm package supports integration beside converters, amplifiers, and interface circuits. For precision designs, evaluate the target's specified ADC, voltage range, reference accuracy, and noise performance in the manufacturer datasheet; applications requiring a documented 12-bit SAR ADC at 1 MSPS should examine CY8C5468LTI-LP026 as the PSoC 5LP migration option.

Human-Machine Interface Controller
The CY8C5468LTI-037 can support compact human-machine interface controllers that coordinate displays, buttons, indicators, and local diagnostic functions. Its 67 MHz processing capability allows the firmware to combine interface updates with system supervision, and 256 KB of flash provides sufficient storage for graphics tables, menus, and control logic. The small 68-QFN package assists integration into space-constrained panels and control modules. Verify the available programmable digital resources, interrupt behavior, and external display-interface requirements in the manufacturer datasheet, and validate that switching noise from attached drivers does not impair sensitive measurements elsewhere in the system.
Disebarkan
Programmable Embedded Platform
The CY8C5468LTI-037 works well as the basis of a programmable embedded platform whose peripheral set may evolve across product variants. The PSoC 5 architecture combines a 32-bit Cortex-M3 core with configurable resources, allowing common hardware to support several control or interface configurations. A 67 MHz operating speed and 256 KB of flash provide a practical balance for protocol handling, real-time control, and configuration storage, while the 68-QFN package supports compact multi-board products. Before production, freeze the peripheral configuration, review boot and watchdog behavior, and test the production programming process to guarantee that each unit receives the intended firmware and configuration.

Catatan Desain
Use the manufacturer land-pattern drawing for the 68-QFN 8 x 8 mm package rather than creating a footprint from terminal count alone. Confirm pad dimensions, solder-mask clearance, paste pattern, and the treatment of any exposed thermal pad. Place the required input and output capacitors directly beside their associated supply pins, and provide a continuous ground return around the device where the layout rules permit.
Separate clock, high-speed serial, and sensitive analog signals from switching nodes and noisy peripherals. The 67 MHz Cortex-M3 core can produce fast edge rates, so maintain short return paths and avoid routing communications signals beneath the QFN or potential exposed-pad area. Review the configured PSoC peripheral locations in the device configuration and update the PCB only after those assignments have been finalized.
Do not assume that CY8C5668LTI-LP014 is firmware-compatible with the original PSoC 5 device merely because it is the manufacturer-designated equivalent. PSoC 5LP migration can affect clock trees, peripheral mappings, interrupts, and configuration data. Run a hardware regression that covers startup, reset, brownout, communications, timing-critical peripherals, and production programming before releasing the alternate part for production.
Confirm the device's operating-voltage range, regulator tolerances, and current limits in the manufacturer datasheet before defining the power architecture. The original device's voltage range is not stated in the distributor listing, so the board should not be designed around an assumed range. Use validated local regulation, adequate startup margin, and decoupling recommendations appropriate to the selected clock and peripheral configuration.
Maklumat Kesediaan
