Product details
Overview
CY8CEBIKEAZI-111 from Infineon Technologies is a PSoC 4 programmable system-on-chip integrating an ARM Cortex-M0+ CPU, configurable analog and digital peripherals, 128 KB flash, 16 KB SRAM, and CapSense capacitive sensing capability. It operates at up to 48 MHz, supports 1.71–5.5 V supply, and targets embedded human-interface applications requiring integrated mixed-signal control and touch sensing.
For engineers reviewing the CY8CEBIKEAZI-111 datasheet, CY8CEBIKEAZI-111 pinout, CY8CEBIKEAZI-111 application, or CY8CEBIKEAZI-111 equivalent, key selection criteria include its CapSense channel count, flash retention specification, USB 2.0 FS device support, and industrial temperature range (–40°C to +85°C) for reliable operation in consumer and industrial HMI designs.
Technical Context
The CY8CEBIKEAZI-111 implements a single-core ARM Cortex-M0+ processor with 32-bit architecture and Thumb-2 instruction set, executing code from on-chip flash with zero-wait-state access up to 24 MHz. It integrates a programmable analog block (PAB) supporting op-amps, comparators, and IDACs, alongside a digital system with UDB-based logic and serial communication blocks (I²C, SPI, UART).
CapSense subsystem includes 24 self-capacitance or mutual-capacitance sensing channels with SmartSense auto-tuning, enabling robust touch button, slider, and proximity detection without manual calibration. USB 2.0 Full-Speed device controller supports HID and CDC class implementations directly from firmware.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4248LQI-BL553 | Same PSoC 4 family, 256 KB flash, no USB PHY - requires external transceiver for USB connectivity | Suitable where USB is not required but higher flash density needed for complex GUI logic | Select when firmware size exceeds 128 KB and USB is unnecessary or implemented externally |
| STM32F072RBT6 | ARM Cortex-M0, 128 KB flash, 16 KB SRAM, no integrated CapSense - requires external touch controller or GPIO-based RC network | Better suited for cost-sensitive applications with simple button-only UI and no proximity sensing | Choose when CapSense channel count < 8 and analog front-end integration is not required |
Compared with CY8CEBIKEAZI-111, CY8C4248LQI-BL553 offers more flash but lacks USB PHY, while STM32F072RBT6 reduces CapSense integration burden but increases component count and layout complexity for touch functionality.

FAQ
What is the maximum operating frequency of the CY8CEBIKEAZI-111's CPU core?
The CY8CEBIKEAZI-111 features an ARM Cortex-M0+ core rated for up to 48 MHz operation. This frequency is achievable across the full industrial temperature range (–40°C to +85°C) and 1.71–5.5 V supply voltage, with zero-wait-state flash access up to 24 MHz and one wait-state above that threshold.
Does the CY8CEBIKEAZI-111 support USB device functionality without external components?
Yes. The CY8CEBIKEAZI-111 integrates a full-speed USB 2.0 device controller with on-die transceivers, supporting D+ and D– signaling directly through P1[0] and P1[1]. No external PHY or level-shifting components are required for basic HID or CDC operation.
How many CapSense channels does the CY8CEBIKEAZI-111 support in mutual-capacitance mode?
The CY8CEBIKEAZI-111 supports up to 24 CapSense channels in mutual-capacitance configuration, enabling implementation of multi-segment sliders, matrix keypads, or proximity sensors. Channel allocation is software-configurable via the CapSense Component in PSoC Creator.
Is the CY8CEBIKEAZI-111 qualified for automotive applications?
No. The CY8CEBIKEAZI-111 is specified for industrial temperature range (–40°C to +85°C) and is not AEC-Q100 qualified. For automotive use, Infineon recommends the PSoC 4 Automotive family (e.g., CY8C4045AZI-S413), which includes extended temperature support and automotive-grade qualification.
