Product details
Overview
CY8C4247AZI-L475 from Infineon is a PSoC™ 4200L programmable system-on-chip featuring a 48 MHz Arm® Cortex®-M0 CPU, 256 kB flash, 32 kB SRAM, four opamps with comparator mode, and dual CAN controllers. It integrates programmable analog/digital blocks, capacitive sensing (CSD), and USB Full-Speed for embedded control in industrial HMI and automotive body electronics.
For engineers reviewing the CY8C4247AZI-L475 datasheet, CY8C4247AZI-L475 pinout, CY8C4247AZI-L475 application, or CY8C4247AZI-L475 equivalent, key selection criteria include Deep Sleep current (20 nA), 94 GPIOs with CAPSENSE™ support, 8 TCPWM blocks, dual CAN 2.0B interfaces, and VFBGA-124 package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The device implements a tightly coupled mixed-signal architecture where the Arm® Cortex®-M0 core executes firmware while eight Universal Digital Blocks (UDBs) provide hardware-reconfigurable logic for real-time signal processing. Analog subsystems include four CTBm opamps with Deep Sleep operation and two low-power comparators.
Its clock system combines IMO (internal main oscillator), ILO (internal low-speed oscillator), and external crystal/PLL support to drive four reconfigurable Serial Communication Blocks (SCBs) - each capable of I²C, SPI, or UART - plus dedicated USB and dual CAN controllers with message RAM and filtering.

Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CSD calibration eliminates manual sensor tuning and maintains stable touch performance across temperature/humidity variations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-BL483 | Same PSoC™ 4200L family; differs in flash/SRAM (256/32 kB same), but uses QFN-68 package and lacks USB interface. | Suitable for space-constrained designs needing CAN + CAPSENSE™ but no USB connectivity or VFBGA assembly. | Select when board layout requires smaller footprint and USB is unused; verify CAN routing and thermal pad soldering process compatibility. |
| STM32G474RET6 | Arm® Cortex®-M4F @ 170 MHz, 512 kB flash, 128 kB SRAM, no integrated CAPSENSE™ or programmable analog/digital blocks. | Better for compute-intensive tasks (e.g., motor FOC), but requires external touch controller and analog signal chain components. | Choose when floating-point math or higher clock speed dominates design needs, and system cost allows added analog peripherals. |
Compared with CY8C4247AZI-L475, CY8C4248LQI-BL483 trades USB and package size for identical mixed-signal capability, while STM32G474RET6 delivers higher CPU performance at the expense of integrated analog flexibility and touch functionality - making the CY8C4247AZI-L475 optimal for compact, sensor-rich, low-power HMI systems.

FAQ
What development tools support CY8C4247AZI-L475 firmware and hardware configuration?
CY8C4247AZI-L475 is fully supported by Infineon's free PSoC™ Creator IDE, which enables schematic-based hardware design, automatic analog/digital routing, and API-driven firmware generation. Debug and programming use MiniProg4 or KitProg2 interfaces. ARM GCC and Keil MDK toolchains are also compatible post-configuration.
Does CY8C4247AZI-L475 support true hardware-based capacitive touch with water tolerance?
Yes. Its dual Capacitive Sigma-Delta (CSD) blocks deliver >5:1 signal-to-noise ratio and built-in water rejection through shield electrode support and adaptive baseline tracking. SmartSense™ auto-tuning configures sensitivity thresholds automatically, eliminating manual calibration for wet or humid environments.
Can the opamps in CY8C4247AZI-L475 operate during Deep Sleep mode?
Yes. All four CTBm opamps retain full functionality in Deep Sleep mode with typical current draw of 1 µA per opamp. They support rail-to-rail input/output, programmable gain, and comparator mode - enabling continuous analog monitoring without waking the CPU.
What is the maximum operating frequency of the CAN controllers on CY8C4247AZI-L475?
The dual CAN 2.0B controllers operate at up to 1 Mbps nominal bit rate. Each includes 32-message object RAM, hardware acceptance filtering, and loopback/self-test modes. Clock source is derived from the internal PLL or external crystal, supporting precise timing for automotive and industrial networks.
