Product details
Overview
CY8C4247LTI-L485 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 automotive body electronics.
For engineers reviewing the CY8C4247LTI-L485 datasheet, CY8C4247LTI-L485 pinout, CY8C4247LTI-L485 application, or CY8C4247LTI-L485 equivalent, key selection criteria include its 48-pin TQFP package, Deep Sleep current of 20 nA, dual CAN 2.0B support, CSD-based touch interface capability, and PSoC™ Creator IDE integration for hardware/firmware co-design.
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-with operation down to 20 nA 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 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LTI-L489 | Same die, 64 kB SRAM (vs. 32 kB), 256 kB flash - higher RAM for RTOS or large buffers. | Better suited for applications requiring FreeRTOS task stacks, audio buffering, or multi-protocol network stacks. | Select when firmware complexity demands >32 kB RAM; pin-compatible but requires updated BOM and layout review for thermal dissipation. |
| STM32G474RET6 | Arm Cortex-M4F @ 170 MHz, no integrated CSD or UDBs; includes FPU and advanced timers. | Lacks native capacitive sensing and programmable logic; relies on external touch controller or GPIO-based solutions. | Choose when floating-point math, high-speed ADC, or DSP functions dominate over mixed-signal configurability. |
Compared with CY8C4247LTI-L485, CY8C4248LTI-L489 offers double SRAM for richer firmware services, while STM32G474RET6 trades PSoC's analog/digital reconfigurability for raw M4F compute performance and peripheral richness - selection hinges on whether design value lies in hardware adaptability or computational throughput.

FAQ
Does CY8C4247LTI-L485 support USB device functionality without external PHY?
Yes. The part integrates a full-speed USB 2.0 device controller with internal transceiver, supporting 12 Mbps operation and Battery Charger Detect (BCD) without external PHY. It requires only standard USB connector wiring and proper VBUS sensing circuitry per Section 2.5.3 of the datasheet.
What development tools are required to program and debug CY8C4247LTI-L485?
PSoC™ Creator IDE (free Windows tool) is required for schematic-based hardware configuration and component-driven firmware generation. Debugging uses SWDIO/SWCLK pins with MiniProg4 or CMSIS-DAP-compliant debug probes. No JTAG adapter is needed.
Can the opamps in CY8C4247LTI-L485 operate independently during Deep Sleep mode?
Yes. All four CTBm opamps retain full functionality-including amplifier, comparator, and ADC buffer modes-at currents as low as 200 nA per opamp in Deep Sleep mode, enabling continuous analog monitoring without CPU intervention.
Is CY8C4247LTI-L485 qualified for automotive applications?
No. While it includes two CAN 2.0B controllers and operates across –40°C to +85°C, CY8C4247LTI-L485 is not AEC-Q100 qualified. For automotive use, Infineon recommends the AEC-Q100 qualified CY8C4247LTI-AI485 variant with identical pinout and feature set.
