Product details
Overview
CY8C4246AZI-L435 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 - deployed in industrial HMI, capacitive touch interfaces, and motor control edge nodes.
For engineers reviewing the CY8C4246AZI-L435 datasheet, CY8C4246AZI-L435 pinout, CY8C4246AZI-L435 application, or CY8C4246AZI-L435 equivalent, key selection criteria include Deep Sleep current (20 nA), CSD-based capacitive sensing SNR (>5:1), USB Full-Speed device support, and 94 GPIOs with configurable drive strength and slew rate.
Technical Context
The CY8C4246AZI-L435 integrates a fixed-function Arm® Cortex®-M0 core with reconfigurable analog (CTBm opamps, SAR ADC, CSD blocks) and digital (UDBs, TCPWM, SCBs) subsystems - enabling hardware-level customization without mask changes. Its clock system includes IMO (8–48 MHz), ILO (32.768 kHz), and external crystal/PLL support for precise timing across sleep/wake transitions.
It implements two independent CAN 2.0B controllers with dedicated message RAM and filtering, plus four SCBs supporting concurrent I²C/SPI/UART configurations - allowing mixed-protocol communication stacks in resource-constrained embedded nodes while maintaining deterministic latency via hardware-triggered TCPWM kill signals.

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0 core in CY8C4246AZI-L435?
The CY8C4246AZI-L435 operates its Arm® Cortex®-M0 CPU at up to 48 MHz, achieved using the internal main oscillator (IMO) or an external crystal with PLL multiplication. This frequency is fully supported across all voltage ranges (1.71–5.5 V) and temperature grades (–40°C to +85°C), with single-cycle multiply ensuring deterministic execution for real-time control tasks.
Does CY8C4246AZI-L435 support hardware-accelerated capacitive sensing?
Yes - it integrates two dedicated Capacitive Sigma-Delta (CSD) sensing blocks with hardware-based SmartSense™ auto-tuning. These blocks deliver >5:1 signal-to-noise ratio and tolerate water overlay, enabling robust touch interfaces without firmware-based calibration routines or external components.
Can the opamps in CY8C4246AZI-L435 operate during Deep Sleep mode?
Yes - all four CTBm opamps retain full functionality in Deep Sleep mode, drawing <1 µA each. They support comparator mode with interrupt generation, enabling analog threshold detection and wake-up events without exiting low-power state - critical for battery-operated sensor nodes.
Is USB device functionality available without external components?
Yes - CY8C4246AZI-L435 includes a full-speed (12 Mbps) USB 2.0 device controller with integrated transceiver, requiring only passive termination (1.5 kΩ pull-up on D+) and standard USB connector. Battery Charger Detect (BCD) is implemented in hardware, enabling automatic identification of charging ports.
