Ultra-low-power programmable system-on-chip devices add integrated USB

September 12, 2013 // By Graham Prophet
Cypress Semiconductor's CCY8C24x93 devices are aimed at development of battery-powered applications: these devices in the PSoC 1 programmable system-on-chip family are the lowest-power and lowest-cost devices in the PSoC 1 family offer 1.1 µA standby mode and 100 nA deep-sleep mode to extend battery life.

The family integrates Full Speed USB 2.0 with a Serial Peripheral Interface (SPI), and come in multiple small-footprint packaging options, including a 3 x 3 mm QFN package. The devices integrate a 10-bit ADC and two comparators, along with 16-bit timers. The combination of the small package sizes and analogue resources suit the family for integrated, space-constrained system solutions that involve basic analogue signal processing, such as data loggers and thermistor hubs. PSoC 1 devices are supported by Cypress’s PSoC Designer Integrated Design Environment (IDE). The IDE features pre-verified, production-ready User Modules - “Virtual Chips” within a PSoC 1 device that replace and integrate multiple chips to create custom solutions. Designers can drop in user modules to implement a wide range of functionality, including a Full Speed USB 2.0 slave, an SPI or I 2C interface, an incremental ADC, or a seven-segment LCD display.

The CY8C24x93 family comes in 8-, 16-, and 32-kB Flash options. The devices also support a wide operating range, allowing full analogue and digital operation from 1.71V to 5.5V, and cost from $0.50 (10,000). unit quantities. Sample and production orders are available today.
