Product details
Overview
CY8C4124AZI-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 deep-sleep operation at 2.5 µA digital current, features three reconfigurable SCB serial interfaces (I²C/SPI/UART), and delivers >5:1 SNR in wet environments-ideal for touch-enabled industrial HMI and consumer control panels.
For engineers reviewing the CY8C4124AZI-S413T datasheet, CY8C4124AZI-S413T pinout, CY8C4124AZI-S413T application, or CY8C4124AZI-S413T equivalent, key selection criteria include its 36 GPIO with CAPSENSE™/analog/digital flexibility, 12-bit 1-Msps SAR ADC with sequencer, TCPWM kill-signal triggering for motor safety, and SmartSense auto-tuning for production-ready touch design.
Technical Context
The device integrates a single-core Arm Cortex-M0+ CPU with tightly coupled flash and SRAM, supported by a hierarchical clock system including ±2% IMO, 32 kHz ILO, and WCO for RTC accuracy. Its analog subsystem includes two continuous-time opamps operable in Deep Sleep, dual low-power comparators, and a dedicated capacitance-sensing delta-sigma block.
Digital resources comprise five 16-bit TCPWM blocks with quadrature decode and comparator-triggered kill signals, three SCBs supporting runtime-reconfigurable protocols, and programmable logic blocks enabling Boolean operations on port signals without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0+, 48 MHz max - enables real-time deterministic control with single-cycle multiply for motor or sensor algorithms. |
| Memory | 64 KB flash + 8 KB SRAM - sufficient for firmware with CAPSENSE™ middleware, communication stacks, and application logic in one chip. |
| ADC | 12-bit SAR, 1 Msps with channel sequencer & averaging - supports high-fidelity multi-channel sensor acquisition with noise reduction. |
| CAPSENSE™ | Sigma-delta CSD with >5:1 SNR and water tolerance - enables reliable touch buttons/sliders in humid or splashed environments. |
| Power Modes | Deep Sleep at 2.5 µA digital + active analog - allows always-on capacitive wake-up while preserving battery life in portable devices. |
| GPIO | 36 programmable pins with configurable drive strength/slew rate - supports mixed-signal routing, LCD segment drive, and ESD-hardened touch inputs. |
| Serial Interfaces | 3 × SCBs, each runtime-configurable as I²C, SPI, or UART - eliminates need for external protocol translators in multi-peripheral systems. |
Pinout & Package
This device is packaged in a 48-lead TQFP (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are fully reconfigurable via firmware, and all GPIO support CAPSENSE™, analog input/output, or digital logic roles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Supports 1.71–5.5 V operation; decoupling required per datasheet layout guidelines for analog stability. |
| XRES | Active-low reset input | Asynchronous hardware reset with internal pull-up; compatible with pushbutton or supervisor IC assertion. |
| SWDCLK / SWDIO | ARM Serial Wire Debug interface | Enables in-circuit programming and real-time debugging without dedicated JTAG pins. |
| P0[0]–P0[7], P1[0]–P1[7], P2[0]–P2[7], P3[0]–P3[7], P4[0]–P4[7], P5[0]–P5[3] | Programmable GPIO | All 36 pins support CAPSENSE™ scanning, analog input buffering, or digital logic with slew-rate control. |
| XTAL_IN / XTAL_OUT | 32 kHz watch crystal oscillator terminals | Connects to external tuning-fork crystal for accurate RTC timing and low-power sleep wake-up. |
Key Features
| Feature | Design Value |
|---|---|
| SmartSense auto-tuning | Hardware-accelerated CAPSENSE™ calibration eliminates manual firmware tuning across temperature/humidity variations. |
| Reconfigurable SCBs | Three independent serial blocks can be assigned I²C, SPI, or UART per runtime need-no hardware redesign required. |
| TCPWM kill signal | Comparator output directly triggers PWM shutdown within one clock cycle-critical for safe motor control loop response. |
| Deep Sleep analog retention | Opamps and comparators remain active during 2.5 µA Deep Sleep mode, enabling capacitive wake-up without full wake. |
| Capacitive sigma-delta CSD | Dedicated hardware block achieves >5:1 SNR and robust water rejection-validated per IEC 61000-4-6 immunity testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4124LQI-S403 | Same core, but 40-pin QFN package and no WCO pins - lacks 32 kHz crystal oscillator support. | Not suitable for RTC-dependent applications like energy metering or time-stamped logging. | Select when board space is constrained and RTC functionality is handled externally or omitted. |
| CY8C4244AZI-S412 | Higher memory (128 KB flash / 16 KB SRAM), same package - adds USBFS peripheral and enhanced TCPWM features. | Required for designs needing USB device connectivity or advanced motor commutation waveforms. | Choose when firmware complexity exceeds 64 KB or USB HID interface is mandatory. |
Compared with CY8C4124LQI-S403, this part enables precise RTC via integrated WCO; versus CY8C4244AZI-S412, it trades USB and extra memory for lower cost and smaller code footprint-ideal for cost-sensitive, touch-centric embedded controllers.

FAQ
Does CY8C4124AZI-S413T support USB connectivity?
No, this part does not include a USB peripheral. It features three SCBs configurable as I²C, SPI, or UART only. For USB device functionality, consider the CY8C4244AZI-S412 or CY8C4247LQI-M485 variants, which integrate USBFS hardware and associated PHY.
What is the maximum operating temperature for CY8C4124AZI-S413T?
The device is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 5.2 of the official datasheet (002-00122 Rev. *Q), and applies to all operating modes including Deep Sleep and full-speed CPU execution.
Can the opamps operate during Deep Sleep mode?
Yes, both continuous-time opamps (CTB) retain full functionality-including gain configuration and output drive-in Deep Sleep mode, drawing only ~100 nA additional current. This enables analog signal conditioning or CAPSENSE™ pre-amplification while the CPU remains powered down.
Is SmartSense tuning compatible with custom PCB layouts?
Yes, SmartSense auto-tuning adapts to parasitic capacitance variations caused by trace length, overlay thickness, or ground plane geometry. It requires no layout-specific calibration constants-tuning runs automatically during initialization or in response to environmental drift.
