Product details
Overview
CY8C4248AZI-L475 from Infineon is a 32-bit Arm® Cortex®-M0 PSoC™ 4200L programmable system-on-chip integrating MCU, reconfigurable analog (4 opamps, 2 comparators, 12-bit SAR ADC), digital logic (8 UDBs), capacitive sensing (CSD), USB 2.0 Full-Speed, dual CAN, and up to 94 GPIOs in a 124-ball VFBGA package. It targets embedded control with integrated signal conditioning and human interface functions.
For engineers reviewing the CY8C4248AZI-L475 datasheet, CY8C4248AZI-L475 pinout, CY8C4248AZI-L475 application, or CY8C4248AZI-L475 equivalent, key selection factors include Deep Sleep current (20 nA), CSD SNR (>5:1), USB + dual CAN coexistence, SmartSense™ auto-tuning, and PSoC™ Creator schematic-based design flow.
Technical Context
The device implements an Arm Cortex-M0 core running at up to 48 MHz with 256 kB flash and 32 kB SRAM, coupled with a dedicated DMA engine (32 channels) for peripheral offload. Its analog subsystem includes four rail-to-rail opamps supporting comparator mode and ADC input buffering, plus two low-power comparators active in Deep Sleep.
Digital flexibility stems from eight Universal Digital Blocks (UDBs), each with 8 macrocells and an 8-bit datapath, enabling custom state machines or logic synthesis via Verilog. Four reconfigurable Serial Communication Blocks (SCBs) support concurrent I²C/SPI/UART, while two independent CAN 2.0B controllers operate with hardware message filtering and FIFO buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 48 MHz max - enables real-time deterministic control with single-cycle multiply for motor or sensor algorithms. |
| Flash / SRAM | 256 kB flash with Read Accelerator, 32 kB SRAM - supports complex firmware with bootloader, secure updates, and data logging buffers. |
| Analog Peripherals | 12-bit SAR ADC (1 Msps), 4 opamps (Deep Sleep capable), 2 comparators - allows simultaneous analog signal acquisition, conditioning, and threshold detection without waking CPU. |
| Digital Logic | 8 UDBs (8 macrocells each), 8 TCPWM blocks - provides hardware-accelerated PWM generation, custom protocol engines, or glue logic without CPU overhead. |
| Communication | 4 SCBs (I²C/SPI/UART), USB 2.0 FS (12 Mbps), 2 CAN 2.0B controllers - enables multi-protocol connectivity including industrial fieldbus and host PC interface in one chip. |

| Power Modes | 20 nA Stop Mode, Deep Sleep with GPIO wakeup - extends battery life in portable HMI or sensor nodes requiring periodic wake events. |
Pinout & Package
Package: 124-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA), 6 × 6 mm, 0.4 mm pitch, RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO0–VDDIO3 | I/O power supply domains | Independent 1.71–5.5 V supplies per port group enable mixed-voltage interfacing (e.g., 3.3 V MCU core + 1.8 V sensor interface). |
| P0.0–P15.7 (up to 94 pins) | Programmable GPIO | Each pin supports CAPSENSE™, analog input/output, digital logic, or serial communication - routed automatically by PSoC™ Creator. |
| USB_DP / USB_DM | USB 2.0 Full-Speed differential pair | Integrated transceiver with Battery Charger Detect (BCD) eliminates external USB PHY and enables plug-and-play charging detection. |
| CAN0_TX / CAN0_RX / CAN1_TX / CAN1_RX | Dual CAN physical layer interfaces | Hardware-filtered CAN message handling with dedicated TX/RX buffers reduces CPU load in automotive body control or industrial PLC nodes. |
| XRES | External reset input | Active-low asynchronous reset with internal pull-up; accepts 1.71–5.5 V logic levels for compatibility with diverse reset supervisors. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ Auto-Tuning | Hardware-accelerated CSD calibration adjusts sensitivity and baseline in real time, eliminating manual tuning across temperature/humidity variations. |
| Deep Sleep Analog Operation | Opamps and comparators remain active at 20 nA system current, enabling continuous analog monitoring (e.g., intrusion detection) without CPU wake. |
| Reconfigurable SCBs | Four serial blocks dynamically switch between I²C master/slave, SPI master/slave, or UART modes at runtime - simplifies BOM by consolidating multiple interface ICs. |
| UDB-Based Logic Synthesis | Verilog or schematic entry compiles into dedicated PLD fabric, delivering deterministic timing for custom protocols (e.g., DALI, LIN) without software latency. |
| Segment LCD Drive | Up to 64 segment/common outputs driven directly from GPIOs in Deep Sleep mode with 4-bit memory retention - enables ultra-low-power display in medical or metering devices. |

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 |
|---|---|---|---|
| CY8C4247AZI-M475 | Same core and peripherals but 128 kB flash / 16 kB SRAM; no USB interface. | Suitable where USB host connectivity is unnecessary and lower code footprint suffices. | Select when cost-sensitive designs omit USB and require smaller memory footprint. |
| STM32G071KBT6 | Arm Cortex-M0+, 64 kB flash, no programmable analog/digital blocks, no CSD, single CAN. | Requires external components for capacitive sensing or custom logic; better for pure control tasks. | Choose when fixed-function peripherals meet requirements and PSoC™ reconfigurability adds unnecessary complexity. |
Compared with CY8C4247AZI-M475 and STM32G071KBT6, the CY8C4248AZI-L475 uniquely combines USB + dual CAN + CSD + programmable analog/digital in one die - critical for space-constrained HMI or automotive nodes needing field-upgradable logic and robust touch.
