N.º de pieza: CY8C4014PVI-422 ✓ ActivoCY8C4014PVI-422 Descripción general
A PSoC (Programmable System-on-Chip) is a mixed-signal microcontroller that integrates a CPU core with configurable analog and digital peripheral blocks plus a routing fabric that connects them to GPIO pins. In the hierarchy of embedded semiconductors, PSoC sits between a plain microcontroller and an application-specific mixed-signal SoC: it is still programmed in C with an Arm Cortex-M core, yet analog functions such as op-amps, comparators and ADCs can be placed and routed at run time instead of being fixed in silicon.
Key features of the CY8C4014PVI-422 include 32-bit Arm Cortex-M0 processing, 16 kByte (16K x 8) flash, 2 kByte of SRAM, a 1.71 V to 5.5 V supply range and a 16 MHz maximum clock. As a member of the CY8C4000 family, it inherits the family characteristic of configurable analog and digital blocks with automatic routing to GPIO pins, which reduces external passive count and lets one footprint serve multiple sensing or interface functions.
Architecturally, the device combines the Cortex-M0 instruction set with dedicated digital blocks such as timers, serial interfaces and a programmable filter block, alongside analog blocks that can be routed to any capable GPIO. The automatic routing fabric is what makes the family distinctive: peripheral placement is decided by firmware, so a board can be reconfigured for different sensor inputs or communication channels without a hardware spin.
Typical applications include low-cost sensor nodes, capacitive-touch keypads, small industrial condition-monitoring modules, USB-connected low-speed data loggers and compact consumer accessories. The SSOP-28 footprint keeps board area low while the 1.71 V minimum supply supports coin-cell and energy-harvesting front ends.
When designing around this part, plan the analog-capable pins carefully: their assignment to internal op-amps or comparators is firmware-driven, so fixing a pin map in the hardware schematic before the firmware block placement is decided is a common source of rework. Confirm the pin package and temperature options in the ordering information table for the PVI suffix.

Aplicaciones típicas
CY8C4014PVI-422 es adecuado para 6 aplicacións: Capacitive-Touch Keypads and Buttons, Industrial Condition-Monitoring Sensors, USB Low-Speed Data Loggers, Smart Home and IoT Sensor Nodes, Compact Consumer Accessories, Programmable Logic and Interface Consolidators.
Capacitive-Touch Keypads and Buttons
The CY8C4014PVI-422 fits capacitive-touch user interfaces because its configurable analog blocks provide the charge-transfer and capacitance-measurement front end on the die, removing dedicated touch controller silicon and external filter networks. With 16 kByte of flash and 2 kByte of SRAM, the Cortex-M0 core can run the touch scanning, debounce and gesture logic alongside a simple application layer. The 1.71 V to 5.5 V supply range allows the keypad to run directly from the same 3.3 V rail as the rest of the panel electronics. Compared with a discrete RC-scan approach, the PSoC routing fabric lets the same board layout support different keypad sizes by changing only the firmware block placement.
Recomendado
Industrial Condition-Monitoring Sensors
Condition-monitoring modules that watch vibration, temperature or humidity benefit from the CY8C4014PVI-422 because the PSoC 4000 architecture combines a 16 MHz Arm Cortex-M0 core with configurable analog and digital blocks on one die. External op-amps and multiplexers can be replaced by internal analog blocks routed to GPIO pins, lowering board area and power draw in a sensor node. The wide 1.71 V to 5.5 V supply range supports both 3.3 V industrial bus taps and lower-voltage battery installations, while 16 kByte of flash is adequate for local filtering, thresholding and a Modbus-style or proprietary serial output. Validate the analog block routing against your sensor impedance before layout release.
Recomendado
USB Low-Speed Data Loggers
Low-speed data loggers and configuration tools use the CY8C4014PVI-422 when a full USB-capable MCU would be overkill but USB connectivity is still required. The 28-SSOP footprint keeps the board compact, and the wide 1.71 V to 5.5 V supply range lets the logger run from a single 3.3 V rail without additional regulation. Its configurable digital blocks can be routed to implement the required communication and storage interfaces, while 16 kByte of flash holds the logging firmware and 2 kByte of SRAM buffers short acquisition bursts. Adding a USB-to-serial bridge keeps the USB electrical requirements outside the sensitive analog portion of the board.
Recomendado
Smart Home and IoT Sensor Nodes
Battery-operated smart-home sensor nodes can be built around the CY8C4014PVI-422 because the 1.71 V minimum supply voltage supports operation directly from a single alkaline cell or a low-voltage energy-harvesting regulator, and the on-chip analog blocks remove the need for always-on discrete sensing front ends. The 16 MHz Cortex-M0 core handles sensor fusion, thresholding and radio-control signalling from 16 kByte of flash with 2 kByte of SRAM. The compact 28-SSOP land pattern leaves board area for the radio module and antenna keep-out. Keep the analog-capable pins away from the switching supply section and follow the layout guidance in the manufacturer datasheet to preserve measurement accuracy.

Compact Consumer Accessories
Small consumer accessories such as personal-care devices, kitchen gadgets and compact appliances benefit from the CY8C4014PVI-422 because a single 28-SSOP device can host the application MCU, motor or solenoid control, and the analog sensing front end in one package. The configurable analog and digital blocks routed to GPIO pins let a single board layout serve multiple product variants with different motor loads and sensor arrangements, changing only firmware. With 16 kByte of flash, 2 kByte of SRAM and a 16 MHz clock, the part handles button handling, motor timing and closed-loop control without a secondary MCU. The low-voltage supply range simplifies powering from the accessory main rail.
Recomendado
Programmable Logic and Interface Consolidators
Interface consolidators that merge several slow serial peripherals into one controller often use the CY8C4014PVI-422 because the PSoC routing fabric can place timers, serial interfaces and logic functions on different GPIO pins without redesigning the board. The 16 MHz Cortex-M0 core handles protocol translation and framing between an upstream host and downstream sensors, while the same silicon can supervise power sequencing through its digital blocks. The 28-SSOP package reduces the pin count compared with discrete logic ICs, and the 1.71 V to 5.5 V supply range supports both 5 V and 3.3 V legacy systems. Firmware-defined block placement makes the same hardware reusable across product generations.

Notas de diseño
Fix the analog-capable pin assignments in the schematic before committing to the PCB. In PSoC 4000 devices the internal op-amps, comparators and ADC channels are routed to GPIO pins by firmware, so a pin that was reserved as a general-purpose IO in the schematic can become unusable for touch sensing or measurement once block placement is locked. Reserve a generous set of analog-capable pins near the connector or sensor, and keep the routing fabric decision inside the firmware configuration step rather than the layout step.
Provide local decoupling close to the supply pins and keep the 28-SSOP footprint within standard assembly capability. Place the bulk and ceramic capacitors on the same side of the board as the device, with the shortest possible loop between the capacitor return and the device ground pins. The 1.71 V to 5.5 V operating range means supply noise directly modulates measurement accuracy in analog sensing designs, so treat the power return path as part of the analog signal path rather than a separate mechanical concern.
Do not assume the flash size of a sibling family member matches. The CY8C4014PVI-422 carries 16 kByte of flash and 2 kByte of SRAM, while lower-numbered members of the same 28-SSOP family ship with less flash, and the CY8C4124PVI-442 offers more. Before swapping a part, rebuild the linked image against the new device and confirm the code plus configuration tables still fit, then re-check the brown-out and clock settings in the device configuration header.
Estimated: with a 3.3 V supply at 16 MHz and typical Cortex-M0 activity, average core current in the low-milliamperes range is expected, but the exact figure depends on the enabled analog blocks and duty cycle. Calculate the supply budget by adding sensor and radio currents to the MCU load and size the input capacitor for the source impedance. The 1.71 V lower limit means a cell stack that sags under load can brown out the part, so include bulk capacitance or a regulator when the source is marginal.
Información de cumplimiento
No RoHS, REACH, lead-free or halogen-free statements appear in the available product information for the CY8C4014PVI-422. Confirm environmental and material compliance on the Infineon product page before release. The device is a general-purpose commercial microcontroller, so AEC-Q100 automotive qualification does not apply unless an automotive-grade ordering code is selected.
