enCoRe MCUs

Cypress Semiconductor Corp. has expanded its line of enhanced component reduction enCoRe products with two new microcontrollers. The enCoRe V full-speed USB peripheral MCUs and enCoRe V LV (low voltage) wireless MCUs offer up to 32Kbyte of flash memory, three 16bit timers and up to 36 GPIOs to accommodate enhanced multimedia features in human interface devices (HIDs). Cypress also introduced the CY3660 enCoRe V/LV development kit, which shortens design time for laser mice, keyboards and game controllers, wireless dongles, remote controls, mobile handset accessories and point-of-sales devices.

The in-system reprogrammable enCoRe V and enCoRe V LV MCUs provide design flexibility with a 10bit ADC, flash memory with EEPROM emulation and small form-factor packages. The enCoRe V devices also include eight USB endpoints. The enCoRe V LV family operates in the full range of 1.7V to 3.6V, with low power consumption for prolonged battery life in wireless applications, especially when paired with Cypress's low-power WirelessUSB LP 2.4GHz radio. All enCoRe MCUs include Cypress's patented crystal-less oscillator and integrated pull-up resistor to reduce component count and BOM cost.

"The enCoRe V and enCoRe V LV families address the growing trend in PC peripheral systems to include enhanced features that require more memory, more I/Os and full-speed USB," said Carl Brasek, director of HID solutions in the USB business unit at Cypress. "Cypress has shipped over one billion USB controllers, and we're committed to maintaining our leadership position by introducing innovative products with unparalleled support."

The CY3660 enCoRe V/LV development kit includes an in-circuit emulator that works in conjunction with actual silicon to provide an accurate and efficient development system. License-free PSoC Designer software included with the kit consists of a graphical user interface, assembler, C compiler, and a linker and debugger for a highly integrated code development environment. Pre-configured code to implement standard-compliant Full-Speed USB and other peripherals simplifies design and shortens development time.

The CY3660 development kit includes: two DVK boards (enCoRe V and enCoRe V LV development boards); two wirelessUSB LP radio modules ; two 12V power supplies and a USB type A to Mini-B cable; PSoC MiniProg for programming the onboard on-chip-debugger chips; LCD module for data display and prototyping; PSoC designer software development tool with complete set of user modules; four firmware examples with complete source code.

Cypress's enCoRe (enhanced component reduction) USB technology features a crystal-less oscillator, ending the need for an external crystal or resonator. Cypress has also integrated other external components commonly found in 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.

The enCoRe V and enCoRe V LV MCUs are currently sampling with production expected in Q3 09. The CY7C643XX enCoRe V devices and the CY7C604XX enCoRe V LV devices are available in 16-, 32-, and 48-pin QFN packages. The CY3660 enCoRe V/LV development kit is available from the Cypress eShop.
