Reported to be the first complete, single-chip, 10/100 Mbps Ethernet device for end-node connectivity, MC9S12NE64 16-bit microcontroller from Freescale Semiconductor replaces more complex, multi-chip devices. NE64 is the first in a series of 16-bit MCUs with embedded Ethernet connectivity, which are designed for affordable industrial control and embedded applications. Based on Freescale's HCS12 central processing unit platform, NE64 contains everything needed for Ethernet connectivity in one package, including a communications stack, flash memory, RAM, media access controller, and a physical-layer transceiver. The microcontroller also features deeply embedded DSP functionality for rapid transceiver operation; 64-KB flash; 10-bit, eight-channel A/D converter; clock-generation module with a phase locked loop; four-channel, 16-bit timer; and two serial communication and one serial peripheral interfaces running at up to 6.25 Mbps. MC9S12NE64 is available in sample quantities, along with a demonstration board and evaluation board.
