Product details
Overview
CY8C4248BZI-L479 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 two CAN controllers. It integrates reconfigurable analog/digital blocks, capacitive sensing (CSD), and USB Full-Speed for embedded control in industrial HMI and automotive body electronics.
For engineers reviewing the CY8C4248BZI-L479 datasheet, CY8C4248BZI-L479 pinout, CY8C4248BZI-L479 application, or CY8C4248BZI-L479 equivalent, key selection criteria include its dual CAN interface, Deep Sleep operation at 20 nA, 94 GPIOs with CAPSENSE™ support, and hardware-accelerated SmartSense™ capacitive tuning.
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-each configurable as amplifier, comparator, or ADC buffer-and two low-power comparators active in Deep Sleep mode.
Digital flexibility derives from eight Universal Digital Blocks (UDBs), each with 8 macrocells and an 8-bit data path, plus four reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART and two fixed-function CAN 2.0B controllers compliant with ISO 11898-1.

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 |
|---|---|---|---|
| CY8C4247LTI-L485 | Same PSoC™ 4200L family; 64-pin TQFP, 256 kB flash, but no USB PHY and only one CAN controller. | Suitable for cost-sensitive CAN-only nodes where USB connectivity and second CAN channel are unnecessary. | Select when board layout requires TQFP and USB/CAN2 are not required. |
| STM32G474RET6 | Arm® Cortex®-M4F @ 170 MHz, 512 kB flash, 128 kB SRAM, no integrated capacitive sensing or UDBs. | Better for math-intensive control loops; lacks hardware CAPSENSE™ and analog reconfiguration, requiring external components for touch. | Choose when floating-point performance dominates over mixed-signal integration and touch capability. |
Compared with CY8C4247LTI-L485, this part adds USB and dual CAN-critical for diagnostics and redundancy. Versus STM32G474RET6, it trades raw compute for on-die analog/digital configurability, reducing external components in sensor-rich designs.
