San Jose, Calif. Cypress Semiconductor Corp.’s new enCoRe III (enhanced component reduction) microcontrollers extend the company’s enCoRe family to full-speed applications (12Mbps signaling rate), while the low-speed enCoRe II devices (1.5Mbps signaling rate ) have added flash memory and reduce overall system costs while increasing performance. The enCoRe family serves a broad range of human interface devices such as mice, keyboards, wireless dongles, and gaming controllers as well as Voice-over-Internet Protocol (VoIP) handsets.
The enCoRe III device has 16 Kbytes of flash memory. It provides users with 16-channel/10 bit analog-to-digital converters for demanding, full-speed USB applications such as gaming controllers. In addition, the enCoRe III provides a Pulse Width Modulator for force feedback gaming capability. The enCoRe III can be used in virtually any full speed application ranging from USB-Serial applications to VoIP Handsets to USB gamepads.
The new enCoRe II microcontrollers are targeted at low-cost USB mice, including trackball, optical, and laser models. The enCoRe II architecture provides many performance and cost options to build the right mouse for multiple markets. Users can choose from 3K to 8K of flash memory to find the appropriate performance and cost combination. In addition, the enCoRe II provides a 3.3V regulator that can power external devices such as an optical sensor.
The enCoRe USB technology features a crystal-less oscillator. By integrating the oscillator on-chip, an external crystal or resonator is no longer needed. Cypress has also integrated other external components commonly found in low-speed USB applications, including pull-up resistors, wake-up circuitry, and a 3.3V regulator. This integration results in shorter development cycles and lower system costs. In addition, the enCoRe family offers a flash-based design that enables storage of wireless binding parameters as well as in-system reprogrammability and EEPROM emulation.
All of the new enCoRe products are available today. The full-speed enCoRe III (CY7C64215) is available in 56-pin QFN and 28-pin SSOP packages and pricing starts under $1.30 in high volumes. The low-speed enCoRe II suite of devices is available in multiple configurations and packages and pricing starts under $0.96 in high volumes. The low-speed enCoRe II suite of devices is available in multiple configurations and packages and pricing starts under 96 cents in high volumes. The 63803 for example goes for 90 cents each in quantities of 100,000 units. With 8 Kbytes of flash, the 63803 is housed in a 16-pin, SOIC.
