Cypress Semiconductor announced the CY8C28xxx PSoC 1 programmable system-on-chip with enhanced analog performance. The programmable analog of the CY8C28xxx device enables more advanced mixed-signal and sensing applications, as well as faster and more robust capacitive touch-sensing interfaces. 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.
The CY8C28xxx PSoC 1 devices offer 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.
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.
