PSoC devices
Cypress Semiconductor has introduced two programmable system-on-chips (PSoCs) with enhanced analogue and digital performance.
The CY8C21x45 and CY8C22xxx PSoC devices are intended to give engineers more design flexibility through greater configurability and the better performance of digital resources for implementing PWMs, timers and communication interfaces such as I2C and SPI.
Leveraging a dedicated dual-channel Capsense capacitive touch-sensing interface, a capability called Capsense Plus allows a single new PSoC device to implement multiple buttons and slider interfaces while managing functions such as motor control, intelligent sensing and light-emitting-diode (LED) control.
The chips target a range of applications across white goods, communications, industrial, automotive, consumer electronics and other markets.
The PSoC architecture integrates programmable analogue and digital blocks with a microcontroller.
The enhanced digital resources on the CY8C21x45 and CY8C22xxx devices offer a hardware real-time clock and PWM deadband and single-/multi-shot support, saving CPU horsepower and engineering development time.
The devices include a faster, dedicated successive-approximation register (SAR) analogue-to-digital converter (ADC) with sample and hold capability, delivering sampling rates up to 150ksps.
They also allow every input/output (I/O) to be analogue or digital with easy accessibility, enabling customers to integrate system peripherals.
The integration offered by the Capsense Plus capability is said to be suitable for white goods and other applications.
