Product details
Overview
CY8C4125AZI-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 digital current, features three reconfigurable serial communication blocks (I²C/SPI/UART), and delivers 12-bit 1-Msps SAR ADC performance for embedded human-interface and sensor-fusion applications.
For engineers reviewing the CY8C4125AZI-S413 datasheet, CY8C4125AZI-S413 pinout, CY8C4125AZI-S413 application, or CY8C4125AZI-S413 equivalent, key selection criteria include its 36 GPIO with CAPSENSE™/analog/digital flexibility, TCPWM-based motor control capability, SmartSense™ auto-tuning for water-tolerant touch, and ModusToolbox™/PSoC™ Creator toolchain support.
Technical Context
The CY8C4125AZI-S413 implements a tightly coupled subsystem where the Arm® Cortex®-M0+ core executes firmware while programmable analog blocks (two opamps, 12-bit SAR ADC, two low-power comparators) and digital logic (five TCPWM blocks, three SCBs) operate concurrently under shared clock domains. Its clock system integrates ±2% IMO, 32 kHz ILO, and WCO for precision timing across sleep/wake transitions.
Capacitive sensing uses sigma-delta modulation with >5:1 SNR and hardware-accelerated SmartSense™ tuning-enabling robust touch detection on any GPIO without external components. The device's Smart I/O block allows state-machine-driven signal conditioning independent of CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0+ @ 48 MHz with single-cycle multiply - enables real-time control loops and deterministic interrupt latency. |
| Memory | 64 KB flash (with read accelerator) + 8 KB SRAM - supports complex firmware with fast code execution and data buffering. |
| ADC | 12-bit SAR ADC @ 1 Msps with differential/single-ended modes and channel sequencer - captures high-fidelity sensor signals with hardware averaging. |
| Capacitive Sensing | Sigma-delta CAPSENSE™ with >5:1 SNR and water tolerance - delivers reliable touch detection in humid or wet environments. |
| Power Consumption | 2.5 µA in Deep Sleep mode with operational analog - extends battery life in always-on UI or sensor nodes. |

| Serial Interfaces | Three reconfigurable SCBs supporting I²C, SPI, or UART simultaneously - simplifies multi-peripheral connectivity without pin conflicts. |
| PWM/Timing | Five 16-bit TCPWM blocks with center-aligned, edge-aligned, and quadrature decode modes - supports motor control, LED dimming, and encoder interfacing. |
Pinout & Package
This device is housed in a 48-lead TQFP package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. All pins support multiple functions via programmable routing, including analog inputs, digital I/O, SCB signals, TCPWM outputs, and CAPSENSE™ electrodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Supports 1.71–5.5 V operation; dual VDD/VSS pairs ensure stable power delivery to analog/digital domains. |

| Reconfigurable SCBs | Three independent serial blocks each configurable at runtime as I²C master/slave, SPI master/slave, or UART - reduces BOM count and PCB complexity. |
| Deep Sleep analog retention | Opamps, comparators, and SAR ADC remain active during Deep Sleep at 2.5 µA - enables continuous sensor monitoring with ultra-low power. |
| Programmable CTB opamps | Two continuous-time opamps supporting high-drive external mode (25 mA) and high-bandwidth internal mode (10 MHz GBW) - usable for signal conditioning or driving LCD segments. |
| TCPWM kill-input triggering | Comparator outputs directly trigger TCPWM shutdown for motor fault protection - eliminates software latency in safety-critical timing paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4126AZI-S433 | Same architecture but with 128 KB flash, 16 KB SRAM, and additional SCB - no change in package or pinout. | Required for larger firmware images or multi-protocol stacks needing extra memory headroom. | Select when firmware size exceeds 64 KB or dual-SCB concurrency (e.g., I²C + UART + SPI simultaneously) is needed. |
| CY8C4025LQI-S402 | Lower-cost variant with 32 KB flash, 4 KB SRAM, no WCO, and reduced GPIO count (28 pins); same 48LD TQFP footprint. | Suitable for cost-sensitive, lower-complexity touch applications without RTC or high-channel-count sensing. | Choose for simplified designs where CAPSENSE™ and basic serial comms suffice, and memory budget is constrained. |
Compared with CY8C4125AZI-S413, the CY8C4126AZI-S433 offers scalable memory for future firmware growth without redesign, while the CY8C4025LQI-S402 trades resources for cost reduction-making it viable only when full 64 KB flash and WCO-based RTC are unnecessary.

FAQ
Does CY8C4125AZI-S413 support USB connectivity?
No, CY8C4125AZI-S413 does not include a USB PHY or controller. It relies on its three reconfigurable SCBs for I²C, SPI, or UART interfaces. For USB host/device functionality, external bridge ICs (e.g., CP210x) or migration to PSoC™ 4 BLE/6 series is required.
What is the maximum operating temperature for this device?
CY8C4125AZI-S413 is rated for industrial temperature range: –40 °C to +85 °C. This specification is validated per Infineon's datasheet Rev. *Q (2024-02-27) and applies to all 48LD TQFP variants including the -S413 speed grade.
Can the SAR ADC perform simultaneous sampling on multiple channels?
No, the 12-bit SAR ADC has a single sample-and-hold circuit and sequences channels sequentially using its hardware channel sequencer. True simultaneous sampling requires external parallel ADCs or devices with multiple independent SAR cores.
Is the WCO (watch crystal oscillator) mandatory for real-time clock functionality?
Yes-the WCO is the only supported clock source for precision RTC operation. While the internal ILO provides 32 kHz timing, its ±50% accuracy makes it unsuitable for timekeeping; the WCO achieves ±20 ppm stability with an external 32.768 kHz crystal.
