Product details
Overview
CY8C4024LQS-S413 from Infineon is a 32-bit Arm® Cortex®-M0+ microcontroller in the PSoC™ 4000S family, integrating programmable analog (CAPSENSE™ v2, dual IDACs, low-power comparators), digital logic blocks, and two reconfigurable serial communication blocks (SCBs). It operates from 1.71 V to 5.5 V, delivers 48 MHz CPU performance, and supports up to 32 KB flash/4 KB SRAM. It is deployed in capacitive touch HMI systems requiring robust water tolerance and low-power deep-sleep operation.
For engineers reviewing the CY8C4024LQS-S413 datasheet, CY8C4024LQS-S413 pinout, CY8C4024LQS-S413 application, or CY8C4024LQS-S413 equivalent, key selection criteria include CAPSENSE™ sigma-delta SNR (>5:1), Deep Sleep current (2.5 µA), TCPWM kill-signal triggering for motor control, and SCB runtime reconfiguration between I²C/SPI/UART modes.
Technical Context
The device implements a single-layer AHB-Lite interconnect linking the Cortex-M0+ core, memory subsystem (32 KB flash with read accelerator, 4 KB SRAM, 8 KB ROM), and peripherals including five 16-bit TCPWM blocks with center-aligned/PWM/comparator-triggered kill functionality. Clocking includes ±2% IMO, 32 kHz WCO, and ILO for low-power timing.
Analog resources are centered on CAPSENSE™ v2 using capacitive sigma-delta modulation for high-SNR touch sensing, supported by two programmable IDACs and two Deep Sleep–capable comparators. Digital flexibility is provided via programmable logic blocks (PLDs) and a high-speed I/O matrix enabling per-pin function assignment across GPIO, analog, or CAPSENSE™ roles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz max - enables real-time firmware execution with single-cycle multiply for sensor fusion or motor control loops. |
| Flash / SRAM | 32 KB flash with read accelerator / 4 KB SRAM - supports moderate firmware footprint with deterministic code fetch latency for time-critical ISRs. |
| CAPSENSE™ SNR | >5:1 signal-to-noise ratio - ensures reliable touch detection under wet conditions and EMI-rich industrial environments. |
| Deep Sleep Current | 2.5 µA digital system current - enables multi-year battery life in portable touch interfaces with periodic wake-up events. |

| TCPWM Blocks | 5 × 16-bit timer/counter/PWM units - support center-aligned PWM, pseudo-random dithering, and comparator-triggered hardware kill signals for safe motor drive. |
| GPIO Pins | Up to 36 programmable pins - any pin supports CAPSENSE™, analog input/output, or digital logic with configurable drive strength and slew rate. |
Pinout & Package
CY8C4024LQS-S413 is housed in a 40-pin QFN package (6 × 6 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are fully configurable via PSoC™ Creator or ModusToolbox™, supporting mixed-signal routing without fixed peripheral pin assignments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Core & I/O supply | 1.71–5.5 V input; powers all digital logic, analog blocks, and GPIO drivers. |
| VSS | Ground reference | Common return path for analog/digital domains; requires low-impedance PCB connection to thermal pad. |

| P0[0]–P0[7], P1[0]–P1[7], etc. | Programmable GPIO | Multi-function pins assignable to CAPSENSE™, ADC, IDAC, SCB, TCPWM, or LCD segment drive at runtime. |
| XRES | External reset | Active-low asynchronous reset input - overrides internal POR and allows system-level recovery from fault states. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense™ auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual tuning effort and maintains sensitivity across temperature/humidity drift. |
| Reconfigurable SCBs | Two serial blocks dynamically switch between I²C master/slave, SPI master/slave, or UART modes without firmware reload or pin remapping. |
| Deep Sleep analog operation | Capacitive sensing and comparator functions remain active while CPU and most digital logic are powered down - enables wake-on-touch with <3 µA total current. |
| Programmable logic blocks (PLDs) | Boolean logic (AND/OR/XOR) applied directly to port inputs/outputs - offloads simple state-machine tasks from CPU to reduce ISR overhead. |
| Hardware kill signal | TCPWM outputs can be disabled within one clock cycle upon comparator threshold violation - critical for fail-safe motor control and power stage protection. |

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 |
|---|---|---|---|
| CY8C4024LQI-S403 | Same die, 40-pin QFN but with industrial temperature range (–40°C to +85°C) vs. CY8C4024LQS-S413's commercial range (0°C to +70°C). | Suitable for extended ambient deployments; not rated for consumer-grade cost-sensitive designs. | Select when operating temperature exceeds 70°C or when industrial qualification documentation is required. |
| CY8C4014LQS-S412 | Same package but reduced memory: 16 KB flash / 2 KB SRAM; lacks CAPSENSE™ v2 hardware acceleration and SmartSense™. | Targeted at basic GPIO + UART/I²C control only - no production-ready capacitive touch capability. | Choose only if touch functionality is unnecessary and BOM cost reduction outweighs design flexibility loss. |
Compared with CY8C4024LQS-S413, CY8C4024LQI-S403 adds temperature resilience without functional trade-offs, while CY8C4014LQS-S412 sacrifices CAPSENSE™ performance and memory to meet entry-level price targets - making the S413 optimal for touch-centric, thermally stable designs.

FAQ
Does CY8C4024LQS-S413 support USB connectivity?
No. The device does not include a USB PHY or USB controller. Communication is limited to its two SCBs (I²C/SPI/UART) and optional GPIO-based bit-banged protocols. For USB host/device functionality, an external USB bridge IC or migration to PSoC™ 4100S/4200S series is required.
Can CAPSENSE™ operate while the CPU is in Deep Sleep mode?
Yes. CAPSENSE™ v2 hardware runs independently in Deep Sleep mode using the ILO or WCO clock source. Touch scanning, baseline tracking, and SmartSense™ auto-calibration continue without CPU intervention, consuming only 2.5 µA total system current.
What debug interfaces are supported, and is JTAG available?
CY8C4024LQS-S413 supports ARM Serial Wire Debug (SWD) only - not JTAG. SWD uses SWDCLK and SWDIO pins for full programming, breakpoint debugging, and real-time trace. Debug features can be permanently disabled in firmware to prevent unauthorized access.
Is there hardware support for AES encryption or secure boot?
No. This part lacks dedicated cryptographic accelerators or secure boot ROM. Flash protection bits prevent read-out, but cryptographic operations must be implemented in software using the Cortex®-M0+ core - suitable for basic authentication but not for FIPS 140-2 or PSA Certified Level 2 requirements.
