The CY8CTMA884AA-12 is an affordable, ultra-low-power capacitive sensing microcontroller designed for high-performance consumer electronics and industrial applications. This controller from Cypress allows you to quickly and easily design interactive user interfaces with touch sensing, hot keys and sliders. Its powerful 8-bit core with 8-bit flexible peripherals, and very low 3.0 volt operation allow for design scalability while still providing excellent performance and flexibility in a small footprint.

The CY8CTMA884AA-12 features a variety of peripheral functions, including a 10-bit ADC, 128K Flash memory, 6K bytes of RAM, two analog comparators, and an on-chip 5-bit DAC for noise cancellation. The peripherals are connected to the output of the 8-bit core which has been customized to optimize memory and performance for touch sensing applications. The embedded capacitive sensing peripheral of the CY8CTMA884AA-12 is the Integrated Capacitive Sensor (ICS). This integrated peripheral allows for low power consumption and precise touch sensing. The ICS supports up to 16-sensing channels and features innovative noise cancellation, advanced filtering, and digital averaging techniques to ensure accurate, high-performance touch sensing.

The CY8CTMA884AA-12 also features an array of power-saving techniques that help reduce power consumption and extend battery life. This includes Automatic Low Power (ALP), Low Power Idle Sleep Mode (LPIS), and Ultra Low Power Sleep Modes (ULPS). The ALP feature allows the controller to switch between operating modes, depending on the user interface design and power requirements, automatically activating power-saving features like the sleep modes and wake-up timers. The LPIS and ULPS modes allow for even lower power consumption and extended battery life.

The CY8CTMA884AA-12 provides robustness and reliability with its built-in EMI/RFI filters, data protection, and differential voltages which reduce false triggering caused by switching noise. The controller also features programmable touch detection debounce for improved noise margin, temperature compensation for improved sensitivity of up to +10% in low ambient light conditions, and patent pending acceleration mode which can detect large displacements of up to 2mm.

The CY8CTMA884AA-12 also provides improved user experience with its advanced algorithm library and customizable user interface tools such as sliders, proximity sensors, hot keys, and track pad configurations. The on-chip I2C and SPI ports allow for easy connection of external sensors for applications such as HUDs and remote control applications.

The CY8CTMA884AA-12 also features on-chip security features to protect against unauthorized tampering of product settings with Digital Signature Security (DSS) technology. And the controller has an integrated 12-bit motor controller interface with built-in level shifting for direct connection to a motor driver. The overall power consumption is kept low with its highly optimized architecture and programmable power modes, advanced packaging techniques, and flexible supply voltage range.
