CY8C9560A-24AXI

CY8C9560A-24AXI is a Cypress (now Infineon) PSoC-based capacitive-sensing microcontroller (CapSense MCU). It combines an MCU core with multiple CapSense sensing channels and programmable analog/digital resources, designed to implement touch interfaces (buttons, sliders, proximity) inside a single chip. It typically includes a USB full‑speed device interface (for HID or custom protocol) and general-purpose I/O, timers, ADCs, comparators, and DMA, all configurable via PSoC Creator or CapSense middleware. The -24AXI suffix indicates a 24-pin package variant. Applications include consumer electronics touch controls, appliances, keyboards, and remote controls.

CY8C9560A-24AXI is a Cypress PSoC-based capacitive sensing MCU with an on‑chip CapSense controller. Key features:
- CapSense: up to ~60 touch channels; self- and mutual-capacitance sensing with configurable sensitivity and debounce.
- Programmable analog/digital blocks: ADCs, DACs, op-amps, comparators, and other analog/digital resources.
- MCU core with flexible digital peripherals; clocking suitable for moderate MHz operation.
- Communications: I2C, SPI, and UART.
- Timers, PWM, counters, and other standard peripherals for sensing and control.
- Memory: on-chip Flash and RAM (sizes vary by variant).
- Low-power modes with wake-up options suitable for touch-activated control.
- 24-pin AXI package (QFN/related footprint).
- Operating range: typical 1.8–3.3 V; temperature range suitable for consumer/industrial use (per datasheet).

Pin count: 24 pins (the “-24A”/“AXI” suffix denotes the 24-pin package).
Function: CY8C9560A is a Cypress mixed-signal PSoC family device designed primarily as a capacitive-touch (CapSense) controller and general-purpose programmable system-on-chip. It integrates analog blocks, digital UDBs, GPIOs and standard host interfaces (I2C/SPI/UART) to implement touch-sensing, sensor conditioning, and control/communication functions in embedded applications.

Manufacturer: Cypress Semiconductor Corporation (product line now part of Infineon Technologies following Cypress’s 2020 acquisition).
Type of company: A semiconductor manufacturer that designs and supplies microcontrollers and programmable system-on-chip (PSoC) devices, mixed-signal and analog ICs, memory and wireless/touch-sensing solutions for embedded, industrial, automotive and consumer applications.
