CY8C4244PVI-442 - PSoC 4200 48MHz Cortex-M0 MCU | Infineon
MPN： CY8C4244PVI-442 ✓ 啟用中CY8C4244PVI-442 概覽
A PSoC (Programmable System-on-Chip) is a mixed-signal MCU family that combines a CPU core with a configurable fabric of analog and digital blocks, enabling engineers to instantiate custom peripherals such as op-amps, comparators, DACs, PWMs and timers without discrete external components. PSoC 4200 sits within Infineon's broader MCU hierarchy (Cortex-M0 -> ARM Cortex family -> 32-bit microcontroller -> embedded system-on-chip), and it is positioned as the cost-optimized entry point below PSoC 4100/4100S/4100M and above PSoC 4000S, balancing analog performance with low power consumption.
Key features include operation from 1.71 V to 5.5 V supply (3.3 V/5 V tolerant I/O), low-power modes with down to 60 nA hibernate current, a USB 2.0 Full-Speed device with internal pull-up resistor, hardware I2C/SPI/UART, and an internal main oscillator trimmed to 0.25% accuracy across voltage and temperature. The 28-SSOP footprint is a compact, gull-wing surface-mount package suitable for hand-soldered prototypes and reflow production alike, with the exposed pad providing an additional thermal path for high-activity applications.
The architecture pairs the Cortex-M0 core with a digital system interconnect that can route any GPIO to any peripheral through the UDB fabric - effectively turning the device into a custom-logic-plus-MCU hybrid. The 12-bit SAR ADC, two op-amps and two comparators (referenced in the broader 4200 family datasheet) eliminate the need for external signal conditioning, while hardware CapSense enables touch-button and slider interfaces without dedicated touch ICs.
Typical applications include USB Human Interface Devices (HID) such as mice, keyboards and game controllers, CapSense touch-button control panels for white goods and industrial front panels, sensor conditioning nodes for IoT edge devices, low-cost motor control for small BLDC or stepper fans, and digital power conversion feedback loops. The wide 1.71-5.5 V supply range also makes the part suitable for direct connection to single-cell Li-ion or 3.3 V/5 V regulated rails without level shifters.
When designing with this device, plan for CapSense tuning using Infineon's CY8CKIT-145-40XX prototyping kit and the PSoC Creator IDE; route unused GPIO to fixed states with the internal pull-up/down to avoid spurious wake-ups. For USB applications, ensure the 5 V VBUS rail is decoupled within 25 mm of the VBUS pin, and verify the firmware uses the integrated USB regulator at 3.3 V rather than an external LDO if board area is constrained.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet - including parametric comparisons versus cross-brand ARM Cortex-M0 MCUs in the same 28-SSOP footprint.

典型應用
CY8C4244PVI-442 適用於 6 應用s: USB HID Devices, CapSense Touch Control Panels, IoT Edge Sensor Nodes, Small Motor Control (BLDC / Stepper), Industrial Sensor Signal Conditioning, Digital Power Conversion Feedback.
USB HID Devices
The CY8C4244PVI-442's integrated USB 2.0 Full-Speed controller with internal 1.5 kΩ pull-up makes it an ideal MCU for USB Human Interface Devices such as keyboards, mice, game controllers, and presentation remotes. The 48 MHz Cortex-M0 core runs standard HID class stacks with 4 KB SRAM sufficient for descriptors and HID reports. Place the part with the VBUS pin within 25 mm of the USB connector's VBUS rail; decouple with 1 µF and 0.1 µF ceramics. Compared with discrete MCUs needing an external USB PHY, the integrated controller reduces BOM cost and PCB area by roughly 30%.
推薦
CapSense Touch Control Panels
The CY8C4244PVI-442's hardware CapSense accelerator supports capacitive touch buttons, sliders, and proximity sensors for white goods, industrial control panels, and consumer appliances. The CapSense block scans autonomously, offloading the Cortex-M0 for application logic, and the analog routing fabric allows capacitive sensors to be mapped to any GPIO. Design recommendation: route shield patterns on adjacent layers and tune sensitivity via Infineon's CY8CKIT-145-40XX prototyping kit. A single CY8C4244PVI-442 typically replaces 3-4 discrete touch ICs in a 12-button appliance front panel.
推薦
IoT Edge Sensor Nodes
The CY8C4244PVI-442's 12-bit 1 Msps SAR ADC and analog routing fabric enable direct connection to temperature, light, and analog sensor outputs without external signal conditioning. Its 1.71-5.5 V supply range supports single-cell Li-ion battery operation with up to 60 nA hibernate current for long-life sensor products. Combined with its I2C/SPI/UART peripherals, the part is suitable for IoT edge nodes that collect analog data and forward it via USB or wired serial. Use the integrated op-amps (referenced in the PSoC 4200 family datasheet) for active sensor bias to save an external dual op-amp IC.
推薦
Small Motor Control (BLDC / Stepper)
The CY8C4244PVI-442's four 16-bit TCPWM blocks generate the complementary PWMs needed for small brushless DC or stepper motor commutation up to 48 MHz switching frequency. Combined with the integrated 12-bit ADC for back-EMF sensing, the part provides a one-chip solution for low-power fans, pumps, and hobby servos. Plan TCPWM dead-time insertion in firmware and route the analog sense signals with 4 mm trace spacing to avoid PWM crosstalk. For steppers above 1 A phase current, pair with an external gate driver such as DRV8870 or A4989SLDTR-T.
推薦
Industrial Sensor Signal Conditioning
The CY8C4244PVI-442's combination of integrated op-amps, comparators, and a 12-bit SAR ADC enables compact industrial signal-conditioning front ends for 4-20 mA loops, RTDs and bridge sensors. The 1.71-5.5 V supply, -40C to +85C industrial temperature grade, and hardware CapSense block all suit factory floor deployment. Compare against the ATSAM D20 family: the CY8C4244PVI-442 wins on BOM integration, while ATSAM D20 wins on raw ADC linearity. For multi-loop PLC modules, multiple CY8C4244PVI-442 devices can be daisy-chained via I2C to a master MCU.
推薦
Digital Power Conversion Feedback
The CY8C4244PVI-442's 1 Msps ADC and programmable UDBs enable digital control loops for isolated DC-DC converters, LED drivers, and PoE powered devices. The 48 MHz CPU computes the control law per switching cycle, while the TCPWM blocks generate the gate drive timing. Compared to discrete analog controllers, the digital approach reduces component count and enables firmware-updatable compensation. Verify switching frequency is below 250 kHz so the ADC can sample twice per cycle for adequate phase margin.

設計說明
Place a 1 µF ceramic capacitor within 5 mm of VDDD (pin 9) and another 1 µF within 5 mm of VDDIO (pin 20); add a 0.1 µF decoupling cap adjacent to each supply pin. For USB applications, route VBUS (pin 23) through a ferrite bead before reaching the chip, and place a 4.7 µF bulk capacitor on the VUSB (pin 24) regulator output. The internal LDO generates 1.8 V for the core - do not connect an external 1.8 V supply to VDDD.
Route USB D+/D- (pins 21, 22) as a 90-ohm differential pair with continuous ground reference on the layer below. Use 4-mil trace width with 8-mil spacing on a 4-layer stackup; total length should not exceed 50 mm to avoid signal integrity issues. Keep D+/D- traces away from PWM or switching regulator signals to minimize crosstalk; the CY8C4244PVI-442 datasheet specifies a maximum trace length of 25 mm to a USB connector.
Do not leave unused GPIO floating - configure with internal pull-up or pull-down in firmware to avoid spurious wake-ups from deep-sleep mode. When using CapSense, route the shield electrode traces parallel to the sensor traces on the layer below to minimize parasitic capacitance; avoid placing sensor traces near noisy signals such as PWM or switching regulator nodes. Programming is via SWD (pins 11, 12) - ensure these pins remain accessible or include a 10-pin Cortex Debug header in the layout.
