Microchip Technology, Inc. Controllers ENC28J60T-I/SS

The ENC28J60T-I/SS is a stand-alone Ethernet controller designed for use with microcontrollers via a Serial Peripheral Interface (SPI). It is compliant with IEEE 802.3 standards and supports 10Base-T networks, featuring an integrated MAC and PHY. The controller operates in both full and half-duplex modes and includes programmable features such as automatic retransmit on collision, padding, and CRC generation. This device has an 8-Kbyte dual-port SRAM buffer for transmit and receive operations, along with hardware-managed circular FIFO and internal DMA for efficient data handling. It supports various packet filtering options, including unicast, multicast, and broadcast, and can wake the host based on specific packet criteria. The ENC28J60T-I/SS operates with a supply voltage of 3.1V to 3.6V and is tolerant to 5V inputs. It is available in a 28-pin SSOP package and is suitable for industrial applications with an operating temperature range of -40¬8C to +85¬8C. The device is equipped with multiple interrupt sources and LED outputs for network status indication, making it a versatile choice for integrating Ethernet connectivity into embedded systems.
