Product details
Overview
CY8C4124LQI-S413 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 deep-sleep operation at 2.5 µA, features three SCBs (I²C/SPI/UART), five TCPWM blocks, and 36 GPIOs-used in human-interface touch panels, industrial control HMI, and low-power sensor nodes.
For engineers reviewing the CY8C4124LQI-S413 datasheet, CY8C4124LQI-S413 pinout, CY8C4124LQI-S413 application, or CY8C4124LQI-S413 equivalent, key selection criteria include capacitive SNR (>5:1), Deep Sleep current (2.5 µA), SAR ADC resolution (12-bit, 1 Msps), TCPWM flexibility (center-aligned/edge/pseudo-random), and CAPSENSE™ SmartSense auto-tuning capability.
Technical Context
The device integrates a fixed-function Arm® Cortex®-M0+ core with programmable analog (two opamps, 12-bit SAR ADC, two IDACs, two low-power comparators) and digital (PLD logic, TCPWM, SCB) subsystems. All analog peripherals remain functional in Deep Sleep mode, enabling always-on touch and sensing.
Its clock system includes ±2% IMO, 32 kHz ILO, and WCO support; GPIOs are fully reconfigurable for CAPSENSE™, analog, or digital roles with programmable drive strength and slew rate. The 48-pin TQFP package enables high I/O density while maintaining signal integrity for mixed-signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+, 48 MHz - delivers deterministic real-time control with single-cycle multiply for motor timing and sensor fusion. |
| Memory | 64 KB flash + 8 KB SRAM - sufficient for firmware, CAPSENSE™ tuning data, and buffered sensor processing without external memory. |
| ADC | 12-bit SAR, 1 Msps, differential/single-ended - supports precision analog monitoring (e.g., battery voltage, temperature) with hardware sequencer and averaging. |
| CAPSENSE™ | Sigma-delta CSD with >5:1 SNR and water tolerance - enables robust touch buttons/sliders in humid or wet environments without shielding. |
| Low-Power Mode | Deep Sleep at 2.5 µA with active analog - allows continuous capacitive wake-up detection while preserving battery life in portable devices. |
| Serial Interfaces | 3 × SCBs - runtime-reconfigurable as I²C, SPI, or UART, enabling flexible peripheral connectivity without pin remapping. |
| TCPWM Blocks | 5 × 16-bit Timer/Counter/PWM - supports motor control (quadrature decode, kill signal triggering), LED dimming, and precision timing. |
Pinout & Package
Package: 48-pin TQFP (7 mm × 7 mm, 0.5 mm pitch). Pin functions are fully configurable per GPIO; dedicated power/ground pins ensure stable analog and digital supply separation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDA / VDDD | Analog/Digital Supply | Separate 1.71–5.5 V inputs enable noise isolation between analog sensing and digital logic domains. |
| XRES | Reset Input | Active-low reset with internal pull-up; accepts 1.2–5.5 V logic levels for compatibility with diverse host systems. |
| P0[0]–P0[7], P1[0]–P1[7], P2[0]–P2[7], P3[0]–P3[7] | Programmable GPIO | All 36 pins support CAPSENSE™, analog input/output, or digital logic with configurable drive strength (0.5–20 mA) and slew rate. |
| SWDIO / SWCLK | Debug Interface | Two-pin Serial Wire Debug interface enables in-circuit programming and real-time trace without dedicated debug header. |
| XTAL_IN / XTAL_OUT | WCO Connection | Supports external 32.768 kHz crystal for precise RTC and low-power wake-up timing. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense Auto-Tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual threshold tuning and adapts to environmental drift (e.g., humidity, temperature). |
| Reconfigurable SCBs | Three serial blocks can be independently assigned as I²C master/slave, SPI master/slave, or UART - reduces BOM count and PCB footprint. |
| Deep Sleep Analog Operation | Opamps, comparators, and CSD remain active during 2.5 µA Deep Sleep - enables wake-on-touch without full MCU wake-up latency. |
| Programmable CTB Opamps | Two continuous-time opamps support high-drive external mode (20 mA) or high-bandwidth internal mode (10 MHz GBW) - usable for sensor conditioning or DAC buffering. |
| GPIO Flexibility | Any pin supports analog input, CAPSENSE™ electrode, or digital logic with programmable pull-up/down, open-drain, or strong drive - simplifies layout and reuse across designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4124AZI-S423 | Same core and peripherals, but in 40-pin QFN package with different pin mapping and no WCO pins. | Lacks external 32 kHz crystal support; unsuitable for RTC-dependent applications requiring high timekeeping accuracy. | Select when space-constrained layouts prioritize QFN and RTC functionality is not required. |
| CY8C4024LQI-S412 | Lower memory (32 KB flash, 4 KB SRAM), no TCPWM kill signal triggering, and reduced GPIO count (24 pins). | Cannot support complex motor control or multi-channel sensor aggregation; limited CAPSENSE™ electrode count. | Choose for cost-sensitive, low-complexity touch-only applications where full TCPWM and memory headroom are unnecessary. |
Compared with CY8C4124AZI-S423 and CY8C4024LQI-S412, the CY8C4124LQI-S413 uniquely balances full peripheral set (WCO, 36 GPIO, kill-trigger TCPWM), deep-sleep analog operation, and TQFP manufacturability-making it optimal for production-ready industrial and medical HMI designs requiring field reliability and upgrade path scalability.

FAQ
Does CY8C4124LQI-S413 support USB communication?
No, CY8C4124LQI-S413 does not include a USB PHY or USB controller. Communication is limited to the three SCBs supporting I²C, SPI, and UART protocols. For USB connectivity, external bridge ICs (e.g., CP2102N) or migration to PSoC™ 4000S/4100S+ variants with USBFS are required.
What is the maximum operating temperature for this device?
CY8C4124LQI-S413 is rated for industrial temperature range: −40°C to +85°C ambient. This is confirmed in Section 5.2.1 of the official datasheet (002-00122 Rev. *Q), with validated performance across voltage (1.71–5.5 V) and temperature extremes.
Can the SAR ADC perform simultaneous sampling on multiple channels?
No, the 12-bit SAR ADC uses a single sample-and-hold circuit and sequential channel scanning via hardware sequencer. It does not support true simultaneous sampling. However, channel sequencing with programmable delay and signal averaging provides effective multi-channel acquisition for slow-to-moderate varying signals like temperature or battery voltage.
Is CAPSENSE™ firmware included with the part?
Yes, Infineon provides CAPSENSE™ Tuner and SmartSense auto-tuning components as part of the free PSoC™ Creator IDE and ModusToolbox™ software suite. No additional license or royalty is required-the firmware runs directly on-device and configures itself based on electrode geometry and environment.
