Cypress PSoCs claim superior analog, digital performance


6/15/2009 10:03 AM EDT
SAN FRANCISCO—Cypress Semiconductor Corp. introduced two new PSoC programmable system-on-chips with enhanced analog and digital performance.

The CY8C21x45 and CY8C22xxx PSoC devices are intended to provide more design flexibility through greater configurability and better performance of digital resources for implementing PWMs, timers, communication interfaces such as I2C and SPI, and more, according to Cypress (San Jose, Calif.).

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, LED control and more, according to Cypress. The new chips target a range of applications across white goods, communications, industrial, automotive, consumer electronics and other markets, the company said.

The PSoC architecture integrates programmable analog 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, according to Cypress.

The new devices include a dedicated successive-approximation register analog-to-digital converter with sample and hold capability delivering sampling rates up to 150 ksps, Cypress said. The devices also allow every I/O to be analog or digital with easy accessibility, enabling customers to integrate system peripherals, the company said. More information about the new PSoC devices is available on Cypress's website.

Additional features of the new PSoC devices include:

  • 2-channel dedicated peripherals to implement up to 37 CapSense touch-sensing buttons with support for additional functions
  • Shift function register support
  • Variable length Serial Peripheral Interface (SPI) from 8-bit to approximately 16-bit
  • I2C hardware address matching
  • Hardware Real-Time Clock
  • Dual analog bus for SAR ADC

    • Cypress said it offers multiple kits to streamline design with the new PSoC devices.

    The CY8C21x45 and CY8C22xxx PSoC devices are now in production. They are available in multiple configurations, and come in 44-pin TQFP and 28-pin SOIC packages, Cypress said.

    The CY3280-22x45 Universal CapSense Controller Kit is priced at $199, the CY3280-CPM1 CapSense Plus Module is $99, and the CY3250-22x45 Pod kit is available for $299. The kits are all currently available from the Cypress eShop.
