New Programmable System-on-Chip Integrates Higher Performance Analog-to-Digital Converters and Enhanced CapSense® Touch-Sensing
Cypress Semiconductor Corp. (NYSE:CY) today introduced a new PSoC® 1 programmable system-on-chip with enhanced analog performance. The superior programmable analog of the new CY8C28xxx device enables 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 PSoC 1 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 device supports up to 4 simultaneous Delta-Sigma Analog-to-Digital Converters (ADCs) with 6- to 14-bit resolution options, allowing it to sample up to 4 analog inputs simultaneously at 62 ksps with an aggregate data sample rate of 248 ksps. The device’s 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. 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. More information on the CY8C28xxx PSoC devices is available at www.cypress.com/go/CY8C28xxx.
“The PSoC programmable system-on-chip has experienced tremendous growth with its trademark programmable analog, design flexibility and integration capabilities,” said Gahan Richardson, vice president of Cypress’s PSoC products. “The CY8C28xxx line expands the target applications for the PSoC 1 family by extending the analog performance to a new level.”
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.
Availability
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. For a high-resolution photo of a CY8C28xxx PSoC device, visit www.cypress.com/go/pr/CY8C28xxxPSoCphoto.
PSoC -- Because Change Happens
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. PSoC devices 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.
The new PSoC 3 and PSoC 5 architectures include high-precision programmable analog capability (up to 20-bit resolution for an Analog to Digital Converter) and expanded programmable digital resources integrated with powerful, industry-standard MCU cores and ample memory and communications peripherals. PSoC 3 devices are based on a high-performance 8-bit 8051 processor, while PSoC 5 devices include a powerful 32-bit ARM Cortex-M3 processor. The products provide designers with a seamless, programmable design platform, enabling easy migration from 8 to 32 bits. The robust features of these new solutions dramatically expand the applications and markets that PSoC can address, including automotive, portable medical, industrial and many more. The PSoC 1 family is based on a cost-optimized 8-bit M8C core. More information about PSoC products is available at www.cypress.com/psoc and free online training is at www.cypress.com/psoctraining.
