Upper Saddle River, N.J. Zensys has rolled a ZW0201 controller chip that enables the development of mesh networks in home environments. This controller chip, which is delivered in a 5 x 5-mm QFN package, combines an RF transceiver with an 8051 microcontroller and a 12-bit analog-to-digital converter (ADC). The chip sports several general-purpose I/Os, a power-on reset circuit, a brown-out detector, a Triac controller, a serial peripheral interface, an interrupt controller, and a UART. It also comes equipped with the company's Z-Wave mesh networking protocol software. The ZW0201 is priced below $3 and additional information can be found at: http://www.zen-sys.com/index.php?page=295. Zensys, www.zen-sys.com.
