Product details
Overview
CY8C4246AZI-L445 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 CY8C4246AZI-L445 datasheet, CY8C4246AZI-L445 pinout, CY8C4246AZI-L445 application, or CY8C4246AZI-L445 equivalent, this device supports field-tunable mixed-signal design, low-power Deep Sleep operation (20 nA), and hardware-accelerated CAPSENSE™ with SmartSense™ tuning - critical for touch interface and motor control firmware development.
Technical Context
The CY8C4246AZI-L445 implements an Arm® Cortex®-M0 core with single-cycle multiply and a dedicated DMA engine (32 channels) for offloading peripheral data movement. Its analog subsystem includes four CTBm opamps supporting Deep Sleep mode, two low-power comparators, and a 12-bit SAR ADC with programmable input buffering.
Digital flexibility is delivered via 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 independent CAN 2.0B controllers - enabling concurrent industrial networking and human-machine interface processing.

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 |
|---|---|---|---|
| CY8C4247AZI-L485 | Same package and core; adds 16 kB additional flash (272 kB total) and 4 kB extra SRAM (36 kB) | Better suited for designs requiring larger bootloader, cryptographic libraries, or dual-CAN firmware with extended message buffers | Select when firmware footprint exceeds 256 kB or when future feature expansion is anticipated |
| CY8C4248LQI-BL483 | 68-pin QFN package; same flash/SRAM; lacks USB PHY but adds more GPIOs (98 vs. 94) and enhanced analog routing | Preferred for space-constrained PCBs needing high pin count and no USB connectivity, e.g., motor driver gate control boards | Choose for non-USB applications where board area and GPIO density outweigh integrated USB benefits |
Compared with CY8C4246AZI-L445, the L485 variant offers headroom for firmware growth without changing layout, while the BL483 QFN option trades USB integration for higher I/O count and smaller footprint - making each alternative optimal under distinct mechanical and protocol constraints.

FAQ
Does CY8C4246AZI-L445 support USB device enumeration without external components?
Yes. The part integrates a full-speed USB 2.0 transceiver with Battery Charger Detect (BC1.2) compliance. It requires only standard USB DP/DM routing and 1.5 kΩ pull-up on D+ for enumeration - no external PHY, level shifter, or charger-detection IC is needed.
What is the maximum operating temperature range for CY8C4246AZI-L445?
The CY8C4246AZI-L445 is rated for industrial temperature operation from –40 °C to +85 °C. This is confirmed in Section 5.2.1 of the official datasheet (001-91686 Rev. *L), with validated performance across voltage (1.71–5.5 V) and frequency (up to 48 MHz) within that range.
Can the opamps operate during Deep Sleep mode?
Yes. All four CTBm opamps retain full functionality in Deep Sleep mode with typical current consumption below 1 µA per opamp. They maintain output drive capability and can be used for wake-on-analog-event sensing, as documented in Section 2.3.3 of the datasheet.
How many pins support CAPSENSE™ functionality on CY8C4246AZI-L445?
Up to 94 GPIO pins support CAPSENSE™, including all pins in Port 0 through Port 12 except dedicated power, reset, and crystal oscillator pins. This is explicitly stated in the "Features" section (page 1) and verified in the pinout table (Section 3) of the datasheet.
