Product details
Overview
CY8C4247LTI-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 automotive body electronics.
For engineers reviewing the CY8C4247LTI-L475 datasheet, CY8C4247LTI-L475 pinout, CY8C4247LTI-L475 application, or CY8C4247LTI-L475 equivalent, key selection criteria include Deep Sleep current (20 nA), 94 GPIOs with CAPSENSE™ support, CSD SNR >5:1, and dual CAN 2.0B compliance for real-time networked control systems.
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 operable in Deep Sleep mode and two low-power comparators, all configurable for ADC input buffering or comparator-triggered TCPWM kill signals.
Digital flexibility stems from eight universal digital blocks (UDBs), each with 8 macrocells and an 8-bit datapath, 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 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LTI-L485 | Same package and core; adds 16 kB additional SRAM and one extra SCB block | Better suited for complex protocol stacks requiring multiple concurrent UART/I²C peripherals | Select when firmware complexity demands >32 kB SRAM or fifth serial interface |
| STM32G071CBT6 | Arm® Cortex®-M0+, no integrated CAPSENSE™ or CSD; requires external opamps/comparators for analog sensing | Lacks hardware capacitive sensing and programmable analog; relies on software-based touch algorithms | Choose for cost-sensitive designs where analog sensing is minimal and CAN is not required |
Compared with CY8C4247LTI-L475, CY8C4248LTI-L485 offers expanded memory and serial interface headroom, while STM32G071CBT6 trades integrated analog programmability for lower unit cost and simpler toolchain-but lacks hardware CSD, dual CAN, and Deep Sleep opamp support.

FAQ
Does CY8C4247LTI-L475 support USB device functionality without external PHY?
Yes. The part integrates a full-speed USB 2.0 device controller with on-die transceiver and Battery Charger Detect circuitry. No external PHY or level-shifting components are required for standard USB connectivity at 12 Mbps.
What is the maximum operating frequency of the CAN controllers?
The dual CAN 2.0B controllers operate up to 1 Mbit/s with full ISO 11898-1 compliance. Each uses dedicated clock routing and message RAM, supporting concurrent transmission/reception on separate buses without CPU intervention.
Can the opamps be used during Deep Sleep mode?
Yes. All four CTBm opamps remain functional in Deep Sleep mode with typical current draw below 1 µA per opamp. They retain full configurability for ADC input buffering or comparator operation while preserving low-power state.
How many pins support CAPSENSE™ functionality?
Up to 94 GPIO pins support CAPSENSE™, enabled via the two integrated CSD blocks. Pin assignment is fully flexible in PSoC™ Creator, allowing any combination of pins to serve as sensors or shields without hardware constraints.
