Product details
Overview
CY8C4248LTQ-L485 from Infineon is a 32-bit Arm® Cortex®-M0 microcontroller in the PSoC™ 4200L family, integrating programmable analog (4 opamps, 2 comparators, 12-bit SAR ADC), digital (8 UDBs, 4 SCBs, 2 CAN blocks), and capacitive sensing (CSD) subsystems. It operates from 1.71–5.5 V, delivers 48 MHz CPU performance, and supports up to 256 kB flash/32 kB SRAM for embedded control in industrial HMI and automotive body electronics.
For engineers reviewing the CY8C4248LTQ-L485 datasheet, CY8C4248LTQ-L485 pinout, CY8C4248LTQ-L485 application, or CY8C4248LTQ-L485 equivalent, key selection criteria include Deep Sleep current (20 nA), CAPSENSE™ SNR (>5:1), USB Full-Speed + dual CAN support, and reconfigurable analog/digital routing in PSoC™ Creator.
Technical Context
The device implements an Arm® Cortex®-M0 core with single-cycle multiply, coupled with two independent CAN 2.0B controllers supporting bit rates up to 1 Mbps and integrated bus fault recovery logic. Its analog subsystem includes four CTBm opamps configurable as buffers, comparators, or PGA stages, each with Deep Sleep operation and pin-flexible input routing.
Digital flexibility derives from eight Universal Digital Blocks (UDBs), each containing 8 macrocells and an 8-bit data path, enabling custom state machines or peripheral extensions. Four Serial Communication Blocks (SCBs) support runtime-reconfigurable I²C/SPI/UART, while two CSD blocks deliver hardware-accelerated capacitive sensing with SmartSense™ auto-tuning and water tolerance.

FAQ
Does CY8C4248LTQ-L485 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) without external PHY. It requires only standard USB termination resistors and a crystal oscillator (12 MHz or 24 MHz) for clock generation.
What is the maximum operating temperature for CY8C4248LTQ-L485 in industrial grade?
The CY8C4248LTQ-L485 is rated for industrial temperature range: –40°C to +85°C ambient. Its 48-pin TQFP package has thermal resistance θJA of 52.6°C/W, enabling sustained operation at full speed under natural convection cooling in enclosed enclosures.
Can the CSD blocks perform mutual-capacitance sensing?
No. The two CSD blocks in CY8C4248LTQ-L485 support only self-capacitance sensing with shield electrode capability. Mutual capacitance requires PSoC™ 4100M or PSoC™ 6 devices with dedicated CSD hardware supporting matrix scanning.
Is there hardware support for CAN FD on this device?
No. CY8C4248LTQ-L485 implements two CAN 2.0B controllers compliant with ISO 11898-1:2003, supporting bit rates up to 1 Mbps but not CAN FD features such as flexible data-rate or extended data length. CAN FD requires PSoC™ 6200 series or AURIX™ TC3xx devices.
