Product details
Overview
CY8C4014PVI-412 from Infineon (formerly Cypress) is a 32-bit programmable system-on-chip (PSoC® 4000 family) microcontroller featuring an Arm® Cortex™-M0 CPU running at 16 MHz, 16 KB flash with Read Accelerator, 2 KB SRAM, integrated CapSense® capacitive sensing, two current DACs (IDACs), one low-power comparator, and one 16-bit TCPWM block. It targets compact embedded systems requiring touch interfaces, low-power operation, and mixed-signal integration - such as smart home sensors and portable industrial controls.
For engineers reviewing the CY8C4014PVI-412 datasheet, CY8C4014PVI-412 pinout, CY8C4014PVI-412 application, or CY8C4014PVI-412 equivalent, key selection criteria include its 20 GPIO count, Deep Sleep wake-up on I²C address match, SmartSense™ auto-tuning for 5–45 pF sensor range, 1.71–5.5 V supply range, and SWD debug interface compatibility with industry-standard Arm tools.
Technical Context
The device implements a tightly coupled MCU subsystem with clock-gated CPU in Sleep mode and full subsystem shutdown in Deep Sleep (35 µs wake-up). Its analog resources are purpose-built for capacitive sensing: the CapSense Sigma-Delta (CSD) block delivers high SNR and water tolerance, while the comparator uses a fixed 1.2-V internal reference and supports pin-selectable inputs.
Digital peripherals include a multi-master I²C block capable of address matching during Deep Sleep, and a single TCPWM supporting center-aligned, edge-aligned, and pseudo-random PWM modes with comparator-triggered kill signals - enabling precise timing control in motor drive and safety-critical logic applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 16 MHz max - enables binary-compatible migration to Cortex-M3/M4 and deterministic real-time execution. |
| Flash Memory | 16 KB with Read Accelerator - delivers zero wait-state access at full speed, reducing code fetch latency in time-critical ISR handling. |
| SRAM | 2 KB, zero wait-state - supports fast stack operations and real-time data buffering without performance penalty. |
| CapSense | Cypress CSD architecture with SmartSense™ - automatically tunes sensor response across 5–45 pF range, eliminating manual calibration in production. |
| I²C Block | Multi-master with Deep Sleep address detect - allows wake-up from ultra-low-power state upon targeted slave address match, extending battery life. |
| Power Range | 1.71 V to 5.5 V - supports direct connection to Li-ion, coin-cell, or 3.3/5 V rails without external regulators. |
| TCPWM | 1 × 16-bit timer/counter/PWM - provides flexible waveform generation including center-aligned PWM for reduced EMI in motor control. |
Pinout & Package
CY8C4014PVI-412 is housed in a 28-pin SSOP (Shrink Small Outline Package) with 0.635 mm pitch and exposed thermal pad. Pin functions are fully configurable via PSoC Creator IDE, with dedicated SWD debug pins (SWDIO/SWCLK), I²C SDA/SCL, and GPIOs mapped across Ports 0–2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply input | Accepts 1.71–5.5 V; powers all digital and analog blocks including CapSense modulator. |
| VSS | Ground reference | Common return path for all circuits; must be low-impedance for stable CapSense SNR. |
| SWDIO / SWCLK | Serial Wire Debug interface | Enables full on-chip debugging and flash programming using standard Arm SWD protocol. |
| P0[0]–P0[7], P1[0]–P1[7], P2[0]–P2[3] | Programmable GPIO | 20 total pins; each supports CapSense, analog comparator input, IDAC output, or digital I/O with configurable drive strength. |
| SCL / SDA | I²C serial interface | Supports multi-master operation and Deep Sleep wake-up on address match without CPU intervention. |
| XRES | External reset input | Active-low asynchronous reset; internal pull-up ensures defined state when unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated calibration of CapSense sensors across 5–45 pF range eliminates firmware tuning overhead and improves production yield. |
| Deep Sleep Wake-up on I²C Match | Allows full system power-down while retaining I²C bus monitoring capability - critical for battery-powered remote nodes. |
| Comparator with Fixed 1.2-V Reference | Enables reliable threshold detection for analog inputs without external reference components or calibration. |
| Configurable GPIO Drive Modes | Supports open-drain, strong, resistive pull-up/down, and high-Z states - simplifies interface to diverse peripherals and reduces BOM count. |
| SWD Debug Interface | Industry-standard 2-wire debug enables full visibility into CPU state, memory, and peripherals without requiring JTAG header space. |
Applications
| Smart Appliance Touch Panel | Industrial Sensor Node |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4014LQI-412 | Same core specs but in 24-pin QFN package; lacks XRES pin and has fewer GPIOs (16 vs 20). | Better suited for space-constrained PCBs where external reset is managed elsewhere. | Select when footprint size is critical and Deep Sleep wake-up via I²C suffices without XRES dependency. |
| STM32F030F4P6 | ARM Cortex-M0 at 48 MHz, 16 KB flash, 4 KB SRAM, no integrated CapSense or IDACs; requires external touch controller. | Lower BOM cost for non-touch applications; higher CPU throughput but added design complexity for capacitive sensing. | Select when raw processing headroom matters more than integrated analog sensing and layout simplicity. |
Compared with CY8C4014LQI-412, the PVI-412 offers greater GPIO count and external reset flexibility; versus STM32F030F4P6, it trades raw clock speed for integrated CapSense, lower system-level power, and reduced component count in touch-centric designs.

FAQ
What debug interface does CY8C4014PVI-412 support?
CY8C4014PVI-412 uses the Arm Serial-Wire Debug (SWD) interface with two-wire connectivity (SWDIO and SWCLK). It supports full on-chip debugging, flash programming, and real-time trace without requiring JTAG headers or external pods. The interface is compatible with standard Arm development tools including Keil MDK, IAR Embedded Workbench, and OpenOCD.
Does CY8C4014PVI-412 require external crystals for basic operation?
No. CY8C4014PVI-412 operates from its internal main oscillator (IMO) trimmed to ±2% accuracy at 24 or 32 MHz, and internal low-frequency oscillator (ILO) at 40 kHz. External crystals are optional and only needed for applications requiring tighter timing accuracy (e.g., USB or precise RTC), as the IMO alone satisfies most CapSense and general-purpose MCU timing needs.
How many CapSense electrodes can CY8C4014PVI-412 support?
CY8C4014PVI-412 supports up to 20 CapSense electrodes using its CSD block, limited only by available GPIO pins (20 total) and routing constraints in PSoC Creator. Electrode count is not fixed in hardware - it scales with design configuration, and SmartSense™ auto-tunes each electrode individually across the 5–45 pF range without firmware intervention.
Can CY8C4014PVI-412 operate from a 1.8-V supply?
Yes. CY8C4014PVI-412 is fully specified for operation from 1.71 V to 5.5 V. At 1.8 V, it maintains full functionality including 16 MHz CPU operation, CapSense sensing, IDAC output, and I²C communication. This enables direct use with single-cell Li-ion or NiMH batteries without regulation, and supports brown-out detection down to 1.6 V with configurable reset threshold.
