部品番号: CY8C5248AXI-047 ✓ 生産中CY8C5248AXI-047 概要
A PSoC, or programmable system-on-chip, is a semiconductor platform that combines a microcontroller unit with configurable peripheral blocks. In this architecture, the MCU handles sequential control, while programmable digital, analog, timer, and communication resources can be arranged to match the system requirements. The CY8C5248AXI-047 belongs to the CY8C52 PSoC 5 family, which is intended for mixed-signal embedded designs.
The device is specified with a 40 MHz ARM Cortex-M3 processor core, 32-bit architecture, and 256 KB of flash memory. The 100-LQFP package provides a large pin count compared with smaller microcontroller packages, supporting the PSoC family’s combination of digital control and analog or peripheral connections. A 1.8 V operating or supply indication appears in the product listing information, while the full electrical limits and pin functions must be confirmed in the manufacturer datasheet.
Typical application areas include industrial control equipment, sensor and signal-conditioning systems, embedded measurement products, communications modules, and compact consumer or medical devices. The PSoC architecture is especially useful when a design needs multiple configurable peripheral functions without relying on a large collection of separate discrete ICs.
Designers should use the datasheet pin-description table when assigning the 100 package pins, especially for power, ground, analog, and special-function connections. Decoupling, exposed thermal behavior, programming, and analog calibration should be implemented according to the manufacturer’s recommended application circuit. This page combines the exact catalog identifiers and source links with practical context for selecting, comparing, and integrating the device.

Industrial Control Equipment
The CY8C5248AXI-047 fits embedded industrial-control designs that combine deterministic control tasks with configurable peripherals. Its 40 MHz ARM Cortex-M3 core provides 32-bit processing for supervisory logic, state machines, communications, and data handling, while 256 KB flash supports application firmware and configuration storage. The PSoC 5 architecture is useful when analog sensing, timers, and digital interfaces must share a single mixed-signal device. Designers should reserve the 100-LQFP footprint for the required power, ground, debug, communication, and peripheral signals, then verify every alternate function against the package drawing. The 1.8 V supply indication makes the device relevant to compact low-voltage industrial controllers, but the full electrical operating envelope and temperature grade must be checked in the manufacturer datasheet before production release.
おすすめ
Sensor and Signal Conditioning
The CY8C5248AXI-047 is appropriate for sensor nodes that need local acquisition, filtering, control, and communications in one programmable platform. Its configurable digital and analog peripheral blocks can simplify designs that combine sensor excitation, signal capture, threshold detection, and digital filtering alongside the main MCU workload. The 40 MHz Cortex-M3 core can supervise measurement sequences and handle protocol processing, and the 256 KB flash provides room for embedded algorithms and calibration parameters. The 100-LQFP package exposes substantially more pins than a small QFP, making it practical to route multiple analog and digital resources. Confirm converter, mixer, comparator, and I/O routing details in the PSoC 5 family documentation, because peripheral assignment and pin availability depend on the programmed device configuration.
おすすめ
Embedded Measurement Products
The CY8C5248AXI-047 supports embedded measurement instruments that combine acquisition, control, calibration, and a user or communications interface. The 40 MHz ARM Cortex-M3 core can execute sampling control and measurement algorithms, while the PSoC 5 programmable blocks can add analog and timing functions without requiring a separate microcontroller for every peripheral. With 256 KB flash, the device accommodates firmware, lookup data, calibration tables, and communication routines. Its 100-LQFP footprint offers enough external pins for multiple interfaces and test points, although routing density should be reviewed for signal integrity. Use the manufacturer pin-description table to assign debug, programming, and peripheral functions, and confirm the 1.8 V power architecture and analog supply requirements before final schematic release.
おすすめ
Communications Gateway
The CY8C5248AXI-047 can serve in embedded gateways that monitor local signals and translate them across serial or network-facing interfaces. Its 40 MHz 32-bit Cortex-M3 core handles protocol state machines, data framing, filtering, and supervisory logic, while PSoC 5 configurable resources can provide timers and peripheral functions around those tasks. The 256 KB flash is suitable for firmware and protocol configuration in compact gateways. Because the device offers many external pins in a 100-LQFP package, engineers can route dedicated communication signals and status or control lines without immediately adding an I/O expander. Interface transceivers remain necessary for RS-232 or RS-485 signal levels. Keep communication traces away from sensitive analog paths and follow the datasheet grounding and decoupling recommendations.
おすすめ
Low-Power Consumer Devices
The CY8C5248AXI-047 is suitable for compact consumer products that need programmable mixed-signal control, a conventional Cortex-M3 software ecosystem, and local serial connectivity. The PSoC 5 platform can consolidate control logic and configurable peripheral functions, reducing the number of separate ICs in a device such as a smart appliance controller, interface module, or compact user-control unit. The 40 MHz processor handles responsive control and user-interface tasks, while 256 KB flash holds firmware and configuration. The 1.8 V device indication is compatible with low-voltage system partitioning, although power-gating and shutdown behavior must be designed carefully. For cost-sensitive production, confirm the exact package, temperature grade, lifecycle commitment, and software-tool support with Infineon rather than inferring them from the family name.
おすすめ
Programmable System-on-Chip Platform
The CY8C5248AXI-047 is specifically suited to systems that benefit from PSoC 5’s configurable peripheral architecture rather than a fixed MCU-only feature set. The 40 MHz ARM Cortex-M3 core executes control code, while configurable digital and analog resources can be adapted to functions such as timers, serial interfaces, signal conditioning, or mixed-signal sequencing. Its 256 KB flash supports both firmware and programmable configuration data. The 100-LQFP package exposes a broad set of I/O options and is appropriate for designs where a smaller package would restrict pin multiplexing. Designers should allocate pins before committing to the PCB, review boot and programming requirements, and validate that each configured peripheral has adequate resources and routing. This application is best suited to product families where configurable hardware can reduce development effort across multiple models.

設計ノート
Use the 100-LQFP land pattern and the manufacturer package drawing when defining pads, solder-mask clearances, and copper. Because the package exposes many mixed-signal and debug functions, assign pins before final routing and confirm that alternate peripheral functions remain available after programming. Provide short ground-return paths and place decoupling capacitors adjacent to the associated supply pins according to the datasheet recommendation.
Plan the 1.8 V power architecture around the exact supply and I/O-domain limits in the manufacturer datasheet. Separate analog, digital, and switching-supply return paths where practical, and avoid routing converter current through sensitive signal areas. Check startup, power-sequencing, and brownout behavior before connecting external programming or test equipment.
Configure PSoC analog and digital functions only after reviewing the available routing matrix and pin constraints. Keep clocks and fast digital interfaces away from sensitive analog inputs, use continuous ground references where possible, and reserve test points for debug without introducing long stubs. Validate timing-sensitive interfaces and programmable analog blocks at the intended clock frequency.
Do not assume that the CY8C5248AXI-047 and CY8C5248AXI-047T are different silicon devices: the indexed T variant represents the tape-and-reel ordering format. Conversely, do not treat that packaging equivalence as permission to ignore temperature grade, lot traceability, or production status. Confirm the complete order code and application requirements before releasing the BOM.
コンプライアンス情報
The available product snippets do not state the complete material-compliance status. AEC-Q100 is not applicable because the device is categorized as an industrial embedded microcontroller rather than an automotive-qualified power component.
