San Jose, Calif. - The CY8C28xxx from Cypress Semiconductor Corp. is a new PSoC 1 programmable system-on-chip family with enhanced analog performance. The superior programmable devices enable more advanced mixed-signal and sensing applications, as well as faster and more robust capacitive touch-sensing interfaces.
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.
The new line targets a wide range of embedded applications that take advantage of the enhanced analog and digital peripherals, including industrial control, communication backplane management, white goods and more. The CY8C28xxx PSoC 1 architecture integrates up to 16 programmable analog and 12 digital blocks with an 8-bit microcontroller, a unique combination that offers designers unmatched flexibility.
The devices support up to 4 simultaneous Delta-Sigma Analog-to-Digital Converters (ADCs) with 6- to 14-bit resolution options, allowing them to sample up to 4 analog inputs simultaneously at 62 ksps with an aggregate data sample rate of 248 ksps.
The easy-to-configure dedicated successive-approximation ADC allows designers to sample up to 192 ksps at 8- or 10-bit resolution. With 2 parallel CapSense touch-sensing channels, the new PSoC devices can process twice as much input data at any general purpose I/O pins at the same scanning interval.
With 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. Additional system resources for the CY8C28xxx PSoC 1 device include an SPI interface with between 8- to 16-bit variable-length, a hardware real-time clock and an integrated PWM deadband.
The devices offer multi/single shot support and operation in the extended temperature range of -40C to 85C. The CY8C28xxx devices are software and pin compatible with the popular CY8C27xxx PSoC 1 devices. The CY8C28xxx PSoC 1 devices are now in production. 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.
PSoC devices employ a highly configurable system-on-chip architecture for embedded control design, offering a flash-based equivalent of a field-programmable ASIC without lead-time or NRE penalties. They integrate configurable analog and digital circuits controlled by an on-chip microcontroller, providing both enhanced design revision capability and component count savings.
A single PSoC device can integrate as many as 100 peripheral functions saving customers design time, board space and power consumption while improving system quality and reducing system cost.
