Product details
Overview
CY8C4024LQS-S411T from Infineon is an AEC-Q100 qualified automotive-grade PSoC™ 4000S microcontroller featuring a 48-MHz Arm® Cortex®-M0+ CPU, 32 KB flash, 4 KB SRAM, integrated CAPSENSE™ capacitive sensing with >5:1 SNR, two low-power comparators operating in Deep Sleep mode (2.5 µA system current), and dual reconfigurable serial communication blocks (I²C/SPI/UART) - deployed in automotive body electronics for touch-enabled control panels.
For engineers reviewing the CY8C4024LQS-S411T datasheet, CY8C4024LQS-S411T pinout, CY8C4024LQS-S411T application, or CY8C4024LQS-S411T equivalent, key selection criteria include AEC-Q100 Grade S (–40°C to +105°C), programmable analog/digital routing, TCPWM kill-signal triggering for motor safety, and CAPSENSE™ hardware auto-tuning for wet-environment touch interfaces.
Technical Context
The device integrates a single-layer AHB-Lite bus interconnect linking the Cortex-M0+ core with peripherals including two SCBs, five TCPWM blocks, and a dedicated CAPSENSE™ sigma-delta (CSD) engine. Its analog subsystem includes two current DACs (IDACs) and two low-power comparators with Deep Sleep retention, enabling always-on capacitive wake-up at <2.5 µA.
Digital flexibility is delivered via programmable logic blocks supporting Boolean operations on GPIOs, while clocking relies on IMO (internal main oscillator), ILO (low-speed oscillator), and optional WCO (watch crystal oscillator) - all managed by a centralized clock control unit with dynamic frequency scaling support.

FAQ
What is the maximum operating frequency of the Arm® Cortex®-M0+ core in CY8C4024LQS-S411T?
The CY8C4024LQS-S411T operates its Arm® Cortex®-M0+ CPU at up to 48 MHz, enabled by the internal main oscillator (IMO) with optional PLL multiplication. This frequency is fully supported across the full –40°C to +105°C temperature range and 1.71 V to 5.5 V supply voltage, with deterministic timing for real-time automotive tasks.
Does CY8C4024LQS-S411T support hardware-accelerated cryptographic functions?
No, the CY8C4024LQS-S411T does not include dedicated cryptographic accelerators such as AES or SHA engines. Security relies on flash protection, debug disable, and customer-implemented software algorithms. For hardware crypto, Infineon's PSoC™ 6 or AURIX™ families are recommended alternatives.
Can the CAPSENSE™ block operate during Deep Sleep mode?
Yes, the CAPSENSE™ CSD engine remains fully functional in Deep Sleep mode with only 2.5 µA system current draw. The hardware auto-tuning algorithm continues to run, enabling wake-on-touch events without CPU involvement - critical for battery-powered automotive accessories.
What development tools are officially supported for CY8C4024LQS-S411T firmware creation?
Infineon officially supports PSoC™ Creator IDE (legacy) and ModusToolbox™ (current) for firmware development. Both provide CAPSENSE™ Tuner, TCPWM configuration GUIs, and SCB protocol stack generators. Arm®-compliant tools like Keil MDK and GCC-based builds are also validated via ModusToolbox™ SDK integration.
