Cypress Introduces CY8C28xxx, 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…
