Product details
Overview
CY8C4124LQI-S413T from Infineon is a programmable 32-bit Arm® Cortex®-M0+ microcontroller with 48 MHz CPU, 64 KB flash, 8 KB SRAM, integrated CAPSENSE™ capacitive sensing, and reconfigurable analog/digital blocks. It supports 1.71–5.5 V operation, deep-sleep mode at 2.5 µA, and up to 36 GPIOs-designed for touch-enabled human interface applications in industrial control panels and consumer appliances.
For engineers reviewing the CY8C4124LQI-S413T datasheet, CY8C4124LQI-S413T pinout, CY8C4124LQI-S413T application, or CY8C4124LQI-S413T equivalent, key selection criteria include its integrated 12-bit 1-Msps SAR ADC, dual opamps with deep-sleep operation, SmartSense™ automatic tuning, TCPWM kill-signal triggering for motor safety, and SCB-based I²C/SPI/UART reconfiguration.
Technical Context
The device integrates a single-core Arm® Cortex®-M0+ CPU with hardware multiplier and tightly coupled memory subsystem (64 KB flash + 8 KB SRAM), enabling deterministic real-time execution. Its programmable analog system includes two continuous-time opamps, two low-power comparators, and a 12-bit SAR ADC with sequencer and signal averaging-all operable in Deep Sleep mode.
Digital flexibility is delivered via five TCPWM blocks supporting center-aligned PWM and quadrature decoding, three reconfigurable Serial Communication Blocks (SCBs) for runtime I²C/SPI/UART switching, and Smart I/O for pre-processing logic offload-enabling mixed-signal system-on-chip consolidation without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+ @ 48 MHz with single-cycle multiply - enables efficient firmware execution and real-time control loops. |
| Memory | 64 KB flash (with read accelerator) + 8 KB SRAM - supports medium-complexity embedded applications with firmware updates and data buffering. |
| Analog Peripherals | 12-bit 1-Msps SAR ADC with channel sequencer and averaging; two opamps; two low-power comparators - all functional in Deep Sleep mode for always-on sensing. |

| SmartSense™ Auto-Tuning | Hardware-accelerated CAPSENSE™ calibration adjusts sensor parameters in real time - eliminates factory calibration and compensates for PCB aging, humidity, and temperature drift. |
| TCPWM Kill Signal | Comparator-triggered immediate PWM shutdown across all TCPWM channels - meets functional safety requirements for motor drives and power converters. |
| LCD Segment Drive | Up to 32 segments driven directly from GPIOs without external driver - reduces component count in small-display HMI applications like thermostats and power tools. |
Applications
| Home Appliance Control Panel | Industrial HMI Terminal |
|---|---|
|
Use Scenario: Touch-sensitive front panel on washing machine or oven with waterproof overlay and LED feedback. IC Role / Device Role / Timing Role: Primary MCU executing CAPSENSE™ scanning, LED PWM dimming, and serial communication to main controller. Use Value: SmartSense™ maintains reliable touch detection through condensation and detergent residue; TCPWM provides flicker-free LED dimming with <1% duty cycle resolution. |
Use Scenario: Compact operator interface for PLC-connected machinery with status indicators and emergency stop monitoring. IC Role / Device Role / Timing Role: Standalone HMI controller handling button debouncing, LCD segment driving, and Modbus RTU over UART. Use Value: Integrated SCB configured as UART with hardware flow control ensures robust serial communication; GPIO-driven LCD eliminates external display driver IC. |
| Smart Thermostat Interface | Motorized Valve Controller |
|
Use Scenario: Battery-powered wall-mounted thermostat with capacitive buttons, ambient temperature sensing, and BLE gateway interface. IC Role / Device Role / Timing Role: Low-power system controller managing CAPSENSE™ wake events, 12-bit ADC temperature reading, and SCB-based UART to BLE module. Use Value: 2.5 µA Deep Sleep current extends battery life to >2 years; SAR ADC's signal averaging improves temperature measurement accuracy by 0.3°C RMS noise reduction. |
Use Scenario: Actuator module controlling HVAC damper position with position feedback, overcurrent protection, and soft-start PWM. IC Role / Device Role / Timing Role: Motor control unit generating center-aligned PWM, monitoring current sense via opamp + ADC, and triggering TCPWM kill signal on fault. Use Value: Comparator-based kill signal disables PWM within 100 ns - prevents MOSFET shoot-through during overcurrent; opamp operates in Deep Sleep to monitor standby current. |
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 PSoC™ 4100S architecture but with 32 KB flash, 4 KB SRAM, and no SmartSense™ auto-tuning - requires manual CAPSENSE™ tuning. | Targeted at cost-sensitive, lower-feature HMI where firmware size <32 KB and environmental stability is predictable. | Select when BOM cost is critical and design team has CAPSENSE™ tuning expertise; not suitable for high-humidity or uncalibrated production environments. |
| STM32G031K8T6 | Arm® Cortex®-M0+ MCU with 64 KB flash but no integrated CAPSENSE™, programmable analog, or Smart I/O - requires external touch controller and opamp circuitry. | Applicable where touch is absent or handled externally, and analog functions are minimal or discrete. | Choose only if existing STM32 toolchain familiarity outweighs the need for analog integration; adds ≥3 passive components and layout area vs. CY8C4124LQI-S413T. |
Compared with CY8C4124LQI-S413T, CY8C4024LQI-S403 reduces memory and removes SmartSense™, increasing calibration effort, while STM32G031K8T6 lacks on-die analog reconfigurability - making both less suitable for compact, self-contained touch-and-control SoC designs requiring minimal external components.

FAQ
Does CY8C4124LQI-S413T support USB connectivity?
No, CY8C4124LQI-S413T does not include a USB PHY or USB controller. It relies on external USB-to-UART bridge ICs (e.g., CP2102 or FT232RL) for host communication. The three SCBs support only I²C, SPI, and UART protocols natively - USB must be implemented at the system level.
What development tools are officially supported for this device?
Infineon officially supports ModusToolbox™ (v3.x+) and legacy PSoC™ Creator (v4.4) for CY8C4124LQI-S413T. ModusToolbox™ provides CMSIS-PACK-based BSPs, PDL drivers, CAPSENSE™ Tuner, and middleware; PSoC™ Creator offers schematic-based design entry and automatic analog/digital routing.
Can the SAR ADC perform simultaneous sampling on multiple channels?
No, the 12-bit SAR ADC is single-channel with a hardware channel sequencer. It scans up to 16 channels sequentially with programmable sample time per channel and supports signal averaging (up to 64 samples) per conversion - but true simultaneous sampling across channels is not supported.
Is the 48-pin TQFP package lead-free and RoHS-compliant?
Yes, CY8C4124LQI-S413T uses a lead-free, halogen-free, RoHS-compliant 48-pin TQFP package (7 mm × 7 mm, 0.5 mm pitch) with NiPdAu terminal finish - qualified per JEDEC J-STD-020 moisture sensitivity level 3 and rated for 260°C peak reflow.
