Microchip Technology, Inc. Controllers TMC2084-HT

The TMC2084-HT is a low power CMOS controller designed for use in network applications, operating at a 3.3 Volt power supply with 5 Volt tolerant I/O. It supports a maximum of 15 nodes per network and utilizes an enhanced token passing protocol from ARCNET, featuring a token retry mechanism and packet sizes of 64 or 128 bytes. The device includes a memory mirror for shared memory within the network and offers network standard time synchronization with automatic time stamping. This controller operates in standalone I/O mode without the need for a microcontroller, supporting up to 14 intelligent remote I/O ports with programmable configurations for inputs and outputs. It allows for selectable output types, including push-pull or open-drain, and features an anti-chatter circuit with adjustable sampling frequencies. The TMC2084-HT also provides a flexible transceiver interface, compatible with RS-485 and fiber optics. Housed in a 48-pin TQFP lead-free RoHS compliant package, the device has a compact size of 7 vó 7 mm and operates within a temperature range of 0 to 70 degrees Celsius. This product is suitable for engineers looking for a versatile controller for networked applications requiring low power consumption and robust communication capabilities.
