CY8C3444AXI-116 8-Bit 50MHz 16KB Flash MCU | Infineon
MPN: CY8C3444AXI-116 ✓ Hoạt độngCY8C3444AXI-116 Tóm tắt
A programmable system-on-chip is a microcontroller architecture that combines a CPU, Flash memory, programmable digital and analog blocks, and communication peripherals on one integrated circuit. Within the product hierarchy, the CY8C3444AXI-116 belongs to the PSoC 3 family, combining an 8051-compatible 8-bit MCU core with configurable mixed-signal resources. This integration can reduce the number of discrete components needed when a design requires digital control alongside analog sensing, signal conditioning, or communications.
The principal device characteristics are a 50 MHz clock rating, 16 KB of Flash program memory, and a 100-pin TQFP package. The operating-voltage range of 1.71 V to 5.5 V supports both lower-voltage and conventional 5 V system environments. The PSoC 3 architecture adds configurable blocks rather than relying solely on fixed peripherals, allowing the same device family to address multiple control-panel, embedded sensing, and compact industrial applications.
Program memory, RAM, EEPROM capacity, clock tolerance, and detailed peripheral specifications are not stated in the retrieved product summaries. These parameters must be confirmed in the manufacturer datasheet before final MCU selection. Likewise, the AXI and -116 order-code meanings, temperature range, device revision behavior, and exact pin assignments require verification against the official CY8C34-family documentation. The 14 x 14 mm TQFP format provides 100 external leads and is suitable for conventional surface-mount assembly when the board area and routing density permit.
Typical uses include compact industrial controllers, sensor-interface modules, keypad and display products, building-control equipment, and general embedded-control boards. A design is a strong fit when it benefits from an 8051-compatible software model, mixed-signal programmability, and a low pin-count package relative to more complex microcontroller families. The 50 MHz rating also provides additional execution headroom for interrupt-driven control, communication handling, and state-machine software.
Hardware design should begin with the exact datasheet pin table because this summary does not reproduce individual ball or lead functions. Confirm power pins, decoupling requirements, programming and debug connections, clock requirements, analog inputs, and exposed package details before layout. Because the family supports multiple supply conditions, the external circuitry and decoupling network should be designed for the exact voltage range and operating mode selected for the product.
This product page combines the verified CY8C3444AXI-116 ordering information with engineering-focused selection guidance, a structured specification record, sourcing questions, and design checks. It also identifies the important limitation that no defensible pin-to-pin alternatives were established from the available cross-reference results, preventing unrelated microcontrollers from being presented as drop-in replacements.

Ứng dụng tiêu biểu
CY8C3444AXI-116 phù hợp cho 6 Áp dụngs: Compact Industrial Control Module, Sensor Interface and Signal Conditioning, Communications Gateway, Human-Machine Interface Controller, Building and Environmental Control, Low-Power Embedded Product.
Compact Industrial Control Module
The CY8C3444AXI-116 fits compact control modules that combine an 8051-compatible 8-bit core with configurable digital and analog resources. Its 50 MHz maximum operating frequency provides execution headroom for state-machine logic, interrupt handling, and supervisory communication, while 16 KB of Flash supports a focused firmware image. The 1.71 V to 5.5 V operating range can simplify design planning across low-voltage and 5 V supply environments. Before layout, verify the exact peripheral assignments, power requirements, temperature limits, and 100-pin TQFP footprint in the CY8C34-family documentation.
Được đề xuất
Sensor Interface and Signal Conditioning
The PSoC 3 architecture makes the CY8C3444AXI-116 relevant to sensor-interface products requiring programmable analog and digital behavior alongside an embedded controller. Its 8051-compatible core can execute acquisition sequencing and control logic at rates up to 50 MHz, while 16 KB of Flash accommodates focused application firmware. The 100-pin TQFP provides access to a substantial pin set for sensors, communications, and supporting circuitry. Exact analog ranges, converter performance, routing options, and pin multiplexing must be confirmed in the datasheet before selecting input ranges or external components.
Được đề xuất
Communications Gateway
The CY8C3444AXI-116 can serve as the control processor in a compact communications gateway or protocol bridge where an 8051-compatible MCU, mixed-signal programmability, and 50 MHz execution are useful. The available 16 KB of Flash is suitable for focused protocol and routing firmware rather than large application stacks. Its 1.71 V to 5.5 V range supports multiple rail environments, and the 100-pin package leaves substantial routing flexibility. Interface timing, buffer strengths, available communication peripherals, and pin multiplexing should be reviewed before assigning an external transceiver.
Được đề xuất
Human-Machine Interface Controller
For keypads, display controllers, and compact human-machine interfaces, the CY8C3444AXI-116 provides an 8-bit control core with up to 50 MHz operation and programmable mixed-signal blocks. The 16 KB Flash capacity is appropriate for a focused interface firmware image, while the 100-pin TQFP can support display, keypad, communications, and status circuitry. Designers should confirm the required display interface, timing, GPIO mapping, and auxiliary peripheral set against the exact CY8C3444 device tables rather than assuming every PSoC 3 family member exposes the same resources.
Được đề xuất
Building and Environmental Control
The CY8C3444AXI-116 is suitable for environmental and building-control subsystems that combine local sensing, digital control, and status communication. Its low-voltage operation range begins at 1.71 V, and the 50 MHz 8051-compatible core supports responsive control logic. The 100-pin package provides a practical option for designs needing several discrete inputs, outputs, and communication links without moving to a larger pin-count package. Validate the exact temperature range, analog accuracy, watchdog behavior, and safety margins in the official documentation before using the device in occupied-building or equipment-control products.
Được đề xuất
Low-Power Embedded Product
The CY8C3444AXI-116 can support low-power embedded products when its clocking, sleep behavior, and analog configuration are matched to the workload. The 8051-compatible core runs at up to 50 MHz but need not operate continuously at that rate, and the 1.71 V minimum supply gives designers room to select compatible power-management components. The 16 KB Flash limit makes code footprint planning important. Confirm active and sleep current, wake-up sources, startup behavior, and brownout handling in the exact datasheet before establishing a battery-life target.

Hướng dẫn chọn lựa
Ghi chú thiết kế
Design the 100-pin TQFP footprint from the official package drawing rather than from a generic 100-pin library entry. Confirm lead pitch, exposed-pad or thermal features, body dimensions, pin-one orientation, and solder-mask geometry. Place programming and debug access, decoupling, clock components, and analog inputs according to the manufacturer pin table before routing power or high-speed signals.
Use a supply and decoupling plan that covers the device's documented 1.71 V to 5.5 V range and the voltage conditions of the selected operating mode. Place required capacitors at their associated supply pins, keep the return path short, and confirm whether any external regulator must support an inrush transient. Do not select passive ratings only from the nominal rail value.
Separate analog inputs, references, and sensitive control paths from fast-switching digital nets wherever the datasheet permits. Route clock and programming signals away from analog pins, use a continuous ground reference where practical, and observe the manufacturer's guidance for external crystal, resonator, or internal-clock configurations. Analog performance depends as much on reference quality and grounding as on the nominal converter specifications.
Do not substitute a generic 8-bit MCU solely because it also offers 16 KB of Flash or a 100-lead package. Firmware images, peripheral mappings, interrupt behavior, programming tools, boot logic, clock setup, and package pin assignments must be checked against the exact target. The CY8C3445AXE-107 has 32 KB of Flash and therefore requires a separate memory and compatibility review.
