Cypress Intros New Programmable System-on-Chip

Cypress Semiconductor has introduced a new PSoC 1 programmable system-on-chip with enhanced analog performance.

 

The programmable analog of the new CY8C28xxx device enables advanced mixed-signal and sensing applications, and also capacitive touch-sensing interfaces. In addition, the devices also deliver the “best digital performance” among the PSoC 1 family, including support for directly driving an LCD and dual hardware I2C interfaces, company officials said.

 

The architecture of CY8C28xxx PSoC 1 integrates up to 16 programmable analog and 12 digital blocks with an 8-bit microcontroller. The device supports up to four simultaneous Delta-Sigma Analog-to-Digital Converters, or “ADCs,” with 6- to 14-bit resolution options. Company officials said that this allows it to sample up to four analog inputs simultaneously at 62 ksps with an aggregate data sample rate of 248 ksps.

 

The new PSoC devices features two parallel CapSense touch-sensing channels, enabling the devices to process twice as much input data at any general purpose I/O pins at the same scanning interval.

 

Also, with the two hardware I2C interfaces in a single CY8C28xxx device, engineers can integrates multiple I2C functions simultaneously, such as I2C bus switching, buffering and hot-swapping.

 

The system resources for the CY8C28xxx PSoC 1 device also include an SPI interface with between 8- to 16-bit variable-length, a hardware real-time clock and an integrated PWM deadband.

 

Additionally, the devices offer multi/single shot support and operation in the extended temperature range of -40C to 85C. And, the CY8C28xxx devices are software and pin compatible with the CY8C27xxx PSoC 1 devices.

 

 “The CY8C28xxx line expands the target applications for the PSoC 1 family by extending the analog performance to a new level,” Gahan Richardson (News - Alert), vice president of PSoC products at Cypress, said.

 

The CY8C28xxx PSoC 1 devices are now in production. Company officials said that the line is available in multiple configurations, and comes in a 48-pin QFN package, a 44-pin TQFP package, and 20- and 28-pin SSOP packages.
