Product details
Overview
CY8C4248BZI-L469 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 programmable 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-L469 datasheet, CY8C4248BZI-L469 pinout, CY8C4248BZI-L469 application, or CY8C4248BZI-L469 equivalent, key selection criteria include Deep Sleep current (20 nA), 94 GPIOs with CAPSENSE™ support, dual CAN 2.0B compliance, CSD SNR >5:1, and USB Battery Charger Detect capability.
Technical Context
The device implements an Arm® Cortex®-M0 core with single-cycle multiply and a configurable digital fabric of eight Universal Digital Blocks (UDBs), each with 8 macrocells and an 8-bit datapath. Its analog subsystem includes four CTBm opamps supporting Deep Sleep operation, two low-power comparators, and a 12-bit SAR ADC with programmable input buffering.
Dual CAN 2.0B controllers operate independently with dedicated message RAM and filtering logic; four SCBs provide runtime-reconfigurable I²C/SPI/UART; and two CSD blocks deliver hardware-accelerated capacitive sensing with SmartSense™ auto-tuning and water tolerance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LTI-L485 | Same PSoC™ 4200L family; 68-pin QFN package, no USB PHY, reduced GPIO count (68 vs. 94) | Lacks USB connectivity and has fewer CAPSENSE™-capable pins - suitable for CAN-only edge nodes without host interface | Select when USB is unnecessary and board space constraints favor QFN over VFBGA. |
| STM32G474RET6 | Arm® Cortex®-M4F @ 170 MHz; no integrated CAPSENSE™ or programmable analog fabric; requires external touch controller | Higher CPU performance but lacks hardware-accelerated capacitive sensing and analog reconfiguration - better for compute-intensive control than HMI-centric designs | Select when floating-point math or DSP workloads dominate, and touch is implemented externally. |
Compared with CY8C4248BZI-L469, CY8C4247LTI-L485 trades USB and pin count for smaller footprint, while STM32G474RET6 offers higher CPU throughput at the cost of integrated analog flexibility and touch capability - choice depends on whether HMI integration or computational headroom is primary.

FAQ
Does CY8C4248BZI-L469 support USB device enumeration without external components?
Yes. The part integrates a full-speed USB 2.0 PHY with on-die termination resistors and Battery Charger Detect circuitry. It enumerates as a standard USB device using only passive ESD protection on DP/DM lines and requires no external transceiver or level-shifting components.
What is the maximum operating temperature for CY8C4248BZI-L469 in automotive applications?
CY8C4248BZI-L469 is rated for industrial temperature range (–40 °C to +85 °C). While used in automotive body electronics, it is not AEC-Q100 qualified; Infineon recommends CY8C4248AZI-L477 for automotive-grade qualification per AEC-Q100 Grade 2 (–40 °C to +105 °C).
Can the CSD blocks perform mutual-capacitance scanning for projected-capacitive touchscreens?
No. The two CSD blocks support only self-capacitance scanning for button/slider/wheel interfaces. Mutual capacitance requires dedicated touchscreen controllers such as CapSense™ MBR3 or third-party TSPs; this device targets overlay-free touch panels and proximity sensing.
How many simultaneous CAN messages can be buffered in hardware?
Each CAN controller has 32 message objects with configurable acceptance filtering and transmit/receive FIFOs. With both controllers active, up to 64 independent CAN messages can be managed in hardware without CPU intervention, supporting high-throughput diagnostic and control traffic.
