Product details
Overview
CY8C4248LTI-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 reconfigurable analog/digital blocks, capacitive sensing (CSD), and USB Full-Speed for embedded control in industrial HMI and motor drive interfaces.
For engineers reviewing the CY8C4248LTI-L475 datasheet, CY8C4248LTI-L475 pinout, CY8C4248LTI-L475 application, or CY8C4248LTI-L475 equivalent, key selection criteria include Deep Sleep current (20 nA), 94 GPIOs with CAPSENSE™ support, TCPWM kill-signal triggering, and dual CAN 2.0B compliance for real-time industrial networking.
Technical Context
The device implements an Arm® Cortex®-M0 core with single-cycle multiply and a dedicated DMA engine supporting 32 channels. Its analog subsystem includes four CTBm opamps operating down to 20 nA in Deep Sleep, each configurable as amplifier, comparator, or ADC buffer with pin-flexible routing.
Digital resources comprise eight UDBs (8 macrocells each), four reconfigurable SCBs (I²C/SPI/UART), two independent CAN 2.0B controllers, and eight TCPWM blocks with center-aligned PWM and hardware-triggered kill signals for motor safety logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-L483 | Same core and peripherals but in 68-pin QFN package; lacks VFBGA thermal performance and 94-GPIO density | Better suited for prototyping or space-constrained non-thermal designs where BGA assembly is unavailable | Select when board-level reworkability or standard reflow compatibility outweighs maximum I/O count and thermal efficiency |
| STM32G474RET6 | Arm Cortex-M4F core, higher clock (170 MHz), no integrated CSD or analog routing flexibility; requires external CAN transceivers | Preferred for compute-intensive DSP tasks but adds BOM cost and layout complexity for capacitive sensing or dual CAN | Choose only if floating-point math throughput dominates over mixed-signal integration and low-power peripheral autonomy |
Compared with CY8C4248LTI-L475, the L483 variant trades package form factor for assembly simplicity, while the STM32G474 demands external components to match its integrated analog/digital reconfigurability and dual-CAN capability-increasing design cycle time and test validation scope.

FAQ
Does CY8C4248LTI-L475 support USB device enumeration without external PHY?
Yes. The part integrates a full-speed USB 2.0 device controller with on-die transceiver, supporting 12 Mbps operation and Battery Charger Detect (BCD) protocol. No external PHY or level-shifting components are required for standard USB-CDC or HID class implementations.
What is the minimum supply voltage for Deep Sleep mode with CSD active?
The device maintains full CSD functionality-including SmartSense™ auto-tuning-at 1.71 V supply. Deep Sleep current remains below 1 µA with CSD block enabled and one opamp configured as comparator, verified per datasheet Section 5.3.5.
Can both CAN controllers operate simultaneously on different bit rates?
Yes. Each CAN block has independent clock dividers, bit timing registers, and message RAM. They support concurrent operation at distinct bit rates (e.g., 500 kbps on CAN0, 125 kbps on CAN1) with no shared resource contention or arbitration delay.
Is PSoC™ Creator IDE still supported for CY8C4248LTI-L475 development?
Yes. Infineon continues to provide PSoC™ Creator v4.4 with full component library, code generation, and debug support for CY8C4248LTI-L475. Migration paths to ModusToolbox™ exist but are optional; legacy projects retain full toolchain compatibility.
