Product details
Overview
CY8C4124AZI-443 from Infineon Technologies (formerly Cypress Semiconductor) is a 32-bit Arm Cortex-M0 programmable system-on-chip (PSoC® 4100 family) integrating MCU, reconfigurable analog/digital blocks, 12-bit 806 ksps SAR ADC, two opamps with comparator mode, and two SCBs supporting I²C/SPI/UART. It operates from 1.71 V to 5.5 V and supports Deep Sleep mode with 20-nA current draw, targeting capacitive touch HMI in industrial control panels.
For engineers reviewing the CY8C4124AZI-443 datasheet, CY8C4124AZI-443 pinout, CY8C4124AZI-443 application, or CY8C4124AZI-443 equivalent, key selection criteria include its 32 kB flash / 4 kB SRAM memory footprint, CapSense Sigma-Delta (CSD) support with >5:1 SNR, 48-pin TQFP package with 36 GPIOs, and integrated TCPWM blocks for motor control timing.
Technical Context
The device implements a single-layer AHB-Lite interconnect between CPU, memory, and peripherals, with dedicated clock domains managed by IMO (24 MHz internal main oscillator) and ILO (32.768 kHz low-power oscillator). Power management includes five modes-Active, Sleep, Deep Sleep, Hibernate, and Stop-with hardware-controlled transitions and wake-up sources including GPIO, comparators, and RTC.
Analog subsystem integration includes a configurable CTBm block hosting two opamps (with high-drive external/high-bandwidth internal output), two low-power comparators active in Deep Sleep, and SAR ADC with differential input, channel sequencer, and signal averaging-enabling simultaneous sensor acquisition and real-time threshold detection without CPU intervention.
Key Specifications

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-S412 | Same PSoC 4100 architecture but 16 kB flash / 2 kB SRAM; no CapSense CSD block; 32-pin QFN package. | Limited to simpler HMI or sensor node applications without multi-button touch or LCD drive. | Select when cost sensitivity outweighs CapSense and memory requirements; verify GPIO count sufficiency for target interface. |
| STM32F072CBT6 | Arm Cortex-M0+ core @ 48 MHz; 128 kB flash / 16 kB SRAM; no integrated CapSense or programmable analog; external touch controller needed. | Requires additional ICs for capacitive sensing and analog signal conditioning; higher BOM cost and layout complexity. | Choose if higher clock speed, larger memory, or USB 2.0 device support are mandatory; accept added component count and firmware integration effort. |
Compared with CY8C4124AZI-443, CY8C4024LQI-S412 reduces memory and removes CapSense-suitable for basic control only-while STM32F072CBT6 offers more memory and speed but lacks hardware touch acceleration and reconfigurable analog, increasing system-level design effort and bill-of-materials cost.

FAQ
What debug interfaces does CY8C4124AZI-443 support?
CY8C4124AZI-443 supports Arm Serial Wire Debug (SWD) via P1[0] (SWDIO) and P1[1] (SWCLK) pins. It includes four hardware breakpoints and two watchpoints. Debug is enabled by default and can be disabled in firmware; re-enabling requires full flash erase and reprogramming due to security lock mechanisms.
Does CY8C4124AZI-443 support external crystal oscillators?
Yes, CY8C4124AZI-443 supports external crystals from 4 MHz to 25 MHz connected to XTAL_IN and XTAL_OUT pins. The internal IMO provides 24 MHz clocking without external components, while the ILO delivers 32.768 kHz for low-power timing; crystal use improves frequency accuracy and jitter performance for timing-critical applications.
Can the opamps in CY8C4124AZI-443 drive external loads directly?
Yes, the two integrated opamps support high-drive external mode capable of sourcing/sinking up to ±25 mA into resistive loads, enabling direct driving of LEDs, small solenoids, or analog sensor excitation circuits without external buffer stages-subject to thermal limits and voltage compliance within the 1.71–5.5 V supply range.
Is CapSense functionality available in low-power modes?
Yes, CapSense CSD operation is supported in Deep Sleep mode using the ILO clock source. The hardware sequencer performs touch scans autonomously while CPU remains halted, achieving typical current consumption of 1.3 µA during active sensing-enabling battery-powered devices to maintain responsive touch interfaces without waking the core.
