CY8C5246LTI-029 - 40MHz PSoC 5 MCU | Infineon
部品番号: CY8C5246LTI-029 ✓ 生産中CY8C5246LTI-029 概要
A programmable system-on-chip, or PSoC, is an MCU category that integrates a CPU with configurable digital and analog peripheral blocks. The CY8C52 family belongs to the broader embedded-controller hierarchy: PSoC 5 -> programmable system-on-chip -> microcontroller -> embedded processor -> semiconductor. Its Cortex-M3-based architecture combines conventional firmware-driven control with programmable peripheral routing, reducing the need for discrete logic around sensing and interface functions.
The principal verified features of the CY8C5246LTI-029 include a 40 MHz maximum clock, 64 KB flash memory, 32-bit processing, and a compact 68-QFN package measuring 8 x 8 mm. The -029 ordering option is associated with capacitive-touch human-machine-interface applications, according to the verified product listing. These characteristics support mixed signal and control designs where board area, processing capability, and configurable peripherals are important.
The CY8C5246 family provides a platform for embedded products requiring more flexibility than a basic fixed-function MCU. Its programmable architecture can support control logic, communications, analog measurement, and user-interface functions while retaining conventional microcontroller firmware workflows. This makes the CY8C5246LTI-029 relevant to industrial interfaces, consumer controls, human-machine interfaces, and connected peripheral designs where reducing external component count is beneficial.
Typical uses include capacitive-touch keypads and panels, USB-enabled human-machine interfaces, LIN-connected controls, industrial operator panels, compact embedded controllers, and low-cost consumer peripherals. The 40 MHz Cortex-M3 core provides the processing headroom required for protocol handling, control-loop execution, and supervisory logic, while 64 KB flash provides local program storage for embedded applications.
Design planning should begin with the exact 68-QFN land pattern and thermal pad requirements in the manufacturer datasheet. The verified web data does not include the complete pin names, exposed-pad connection, electrical limits, SRAM capacity, or detailed temperature ratings; these values must be confirmed before schematic capture or PCB release. Component availability and pricing should also be reconfirmed with the selected authorized distributor.
This product page consolidates verified distributor specifications, exact package information, pricing references, compatible family alternatives, and practical engineering guidance. It also clearly identifies unavailable technical fields instead of estimating them, providing a safer basis for sourcing and preliminary design decisions.

主な用途
CY8C5246LTI-029 の用途: 6 件s: Capacitive-Touch Human-Machine Interfaces, USB-Enabled Embedded Controls, LIN-Connected Vehicle and Equipment Controls, Industrial Operator Panels, Consumer Appliance User Interfaces, Low-Cost Connected Peripherals.
Capacitive-Touch Human-Machine Interfaces
The CY8C5246LTI-029 fits capacitive-touch keypads, control panels, and compact human-machine interfaces because the verified product listing identifies it as a capacitive-touch MCU with a 40 MHz ARM Cortex-M3 core. Its 64 KB flash provides local storage for touch-processing firmware, interface state machines, and communication routines. The 68-QFN 8 x 8 mm package also limits PCB footprint compared with a discrete MCU and separate sensing controller. Before layout release, engineers should verify the required touch channels, acquisition timing, electrode configuration, exposed-pad connection, and grounding strategy in the manufacturer documentation.
おすすめ
USB-Enabled Embedded Controls
The CY8C5246LTI-029 can serve as the central controller in a USB-enabled peripheral where firmware must combine protocol handling with configurable control logic. Its verified 40 MHz Cortex-M3 core and 64 KB flash provide a defined baseline for USB task scheduling, device-state management, and local configuration storage. The PSoC architecture can also reduce discrete logic around programmable digital functions. Integration still requires exact USB pin mapping, transceiver requirements, bus-power requirements, and package-level electrical checks because those details are not included in the supplied verified data.
おすすめ
LIN-Connected Vehicle and Equipment Controls
The CY8C5246LTI-029 is suitable for compact LIN-oriented control modules because its verified product description explicitly references USB/LIN use and the device provides a 40 MHz Cortex-M3 core for protocol and supervisory tasks. The 64 KB flash supports embedded application code, while the 68-QFN package supports space-constrained control boards. A production design must confirm the LIN transceiver interface pins, transceiver supply requirements, wake-up behavior, and automotive qualification. The supplied data does not establish AEC-Q100 status or the complete LIN peripheral configuration.
おすすめ
Industrial Operator Panels
The CY8C5246LTI-029 can support compact industrial operator panels that combine touch input, local indication, and supervisory control. Its 40 MHz processing rate allows firmware to service multiple input tasks, while the PSoC family's programmable resources can implement control functions without relying entirely on discrete logic. The 8 x 8 mm 68-QFN package helps minimize board area in densely populated panels. Industrial suitability must be evaluated using the missing supply-voltage, operating-temperature, EMC, and lifecycle data, followed by validation against the actual panel sensor and communication architecture.
おすすめ
Consumer Appliance User Interfaces
The CY8C5246LTI-029 fits consumer appliance controls that need capacitive sensing and programmable logic within a compact board area. The verified 64 KB flash supports local firmware for buttons, indicators, interlocks, and user feedback, while the 40 MHz Cortex-M3 core handles concurrent control functions. Its QFN form factor supports automated assembly but requires adequate thermal-via and exposed-pad layout. Engineers should confirm whether the product's electrical limits suit the selected appliance rail and verify that the default package drawing is replaced by the authoritative 68-QFN drawing before release.
おすすめ
Low-Cost Connected Peripherals
The CY8C5246LTI-029 can be used in low-cost connected peripherals that require more local control capability than a basic 8-bit MCU. Its 32-bit Cortex-M3 architecture operates at 40 MHz, and its verified 64 KB flash is sufficient for many protocol stacks, configuration logic, and control tasks. The 8 x 8 mm package helps reduce board size, while the PSoC concept can consolidate programmable peripheral functions. Actual suitability depends on communication peripheral availability, SRAM, power consumption, and the number of exposed I/O pins, none of which were specified in the supplied distributor snippets.

設計ノート
Do not release the layout from the default package image. The verified device uses a 68-QFN 8 x 8 mm package, but the supplied data does not include the authoritative pin map or exposed-pad connection. Download the manufacturer package drawing, verify pin 1 orientation, place the exposed-pad vias according to its land-pattern guidance, and confirm the thermal-pad net before Gerber release.
The supplied data does not state the operating-voltage range, absolute maximum ratings, or I/O current limits. Before connecting the 40 MHz Cortex-M3 core, sensors, USB, or LIN transceivers, confirm supply and I/O voltage compatibility in the datasheet. Include local bulk and high-frequency decoupling close to the device, and ensure any external transceiver has an independently validated supply arrangement.
Do not treat the 68-QFN footprint as a generic 68-pin QFN. The target is a specific PSoC 5 device whose package can expose a thermal pad and whose multiplexing depends on the programming configuration. Verify the exact ordering option, complete pin names, alternate-function limitations, boot or programming pins, and the exposed-pad connection against the manufacturer documentation before creating a schematic.
Although the verified operating frequency is 40 MHz, device dissipation cannot be calculated from the supplied data because core voltage, active current, and package thermal resistance are absent. Use the manufacturer power-dissipation and thermal-resistance data during worst-case design. Provide copper area and thermal vias under the exposed pad only in accordance with the recommended land pattern, and avoid placing temperature-sensitive components immediately beneath the package.
コンプライアンス情報
The supplied verified web data does not contain explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. These fields remain unknown rather than being inferred from manufacturer identity.
