N.º de pieza: CY8C5466AXI-064 ✓ ActivoCY8C5466AXI-064 Descripción general
A PSoC, or programmable system-on-chip, is a mixed-signal microcontroller architecture that integrates a CPU with configurable analog and digital peripheral blocks. The CY8C54 device family extends the PSoC concept with Arm Cortex-M3 processing, deterministic peripheral resources, and programmable signal-chain functions. This architecture reduces the number of separate components required in sensing, control, and communication-oriented embedded products.
The principal device characteristics include a 67 MHz operating frequency, 64 KB of flash program memory, 16 KB of SRAM, 60 general-purpose I/O pins, and support for 1.8 V, 3.3 V, and 5 V operating voltages. The integrated internal oscillator reduces dependence on an external timing component, while the large pin count provides parallel interface options and extensive peripheral connectivity.
Its programmable architecture allows designers to assign digital functions such as timers, serial interfaces, and logic blocks while also using analog resources for signal conditioning. This configurability is useful when a product must combine control logic with sensor input, waveform generation, data acquisition, or communication functions while maintaining a compact bill of materials.
Typical PSoC 5 applications include industrial sensor controllers, building and automation equipment, consumer interfaces, communications equipment, and compact embedded control systems. The Arm Cortex-M3 processor handles conventional control tasks, while the PSoC peripherals can accelerate input/output operations and reduce reliance on discrete analog and logic ICs.
Designers should verify the pin configuration, power rails, clock requirements, and programmable peripheral assignments in the manufacturer datasheet and PSoC Creator project settings. The 100-pin TQFP footprint is suitable for multilayer boards, but careful grounding, decoupling, and routing of sensitive analog signals remain important for predictable performance.
This page organizes the core MCU specifications, package characteristics, application guidance, comparison considerations, and replacement limits into one engineering reference. It also distinguishes confirmed device attributes from parameters that still require verification against the exact ordering code and manufacturer documentation.

Aplicaciones típicas
CY8C5466AXI-064 es adecuado para 6 aplicacións: Industrial Sensor Controllers, Building Automation Equipment, Consumer Interface Controllers, Communication Equipment, Data Acquisition Modules, LED and Lighting Control.
Industrial Sensor Controllers
The CY8C5466AXI-064 fits industrial sensor controllers that must acquire, condition, and process several signals locally. Its 67 MHz Arm Cortex-M3 core supports responsive control logic, while 64 KB of flash accommodates application firmware and 16 KB of SRAM provides working memory for acquisition and conditioning tasks. The 60 available I/O pins allow sensors, indicators, and communications peripherals to share one controller. According to the Infineon product documentation, configurable digital and analog blocks can reduce the number of separate interface ICs. The trade-off is that the 100-pin TQFP requires careful routing and adequate board area, and the exact operating-temperature grade must be confirmed before deployment in an industrial enclosure.

Notas de diseño
Confirm every supply rail and its permitted sequence in the manufacturer datasheet before laying out the board. The device is associated with 1.8 V, 3.3 V, and 5 V operating options, but those values do not by themselves define every core, analog, or I/O rail. Place the recommended bypass capacitors adjacent to their associated supply pins, provide adequate current margin for 67 MHz operation and configured peripherals, and isolate sensitive analog supply paths from switching and high-current digital returns.
The 100-pin TQFP footprint has fine-pitch leads on all four sides and should be placed on a multilayer board with a continuous ground plane. Keep the MCU footprint free of accidental thermal-pad or exposed-pad assumptions unless the exact package drawing confirms one. Follow the manufacturer land-pattern dimensions rather than creating a footprint from the generic 14 mm body dimension, and provide unobstructed routing access to all peripheral pins.
Separate analog and digital return currents even though the device integrates both functions. Route sensitive analog inputs away from clock, switching-node, and high-current output paths; use a quiet ground reference for analog blocks and place analog input conditioning components close to their associated pins. Confirm which pins are routable in the selected PSoC Creator configuration because assigning a peripheral may restrict alternate functions on the same pad.
Do not treat the -064 suffix as a complete description of the device. Verify the 67 MHz speed grade, memory configuration, package, temperature range, and peripheral set against the exact ordering information. When evaluating the listed alternatives, compare both package pins and firmware configuration; a shared TQFP footprint does not ensure that analog routing, interrupt assignments, clock dividers, or peripheral resources are identical.
