Status: In Production
The TMC2084 is CircLink's standalone mode controller acting as an intelligent remote I/O controller that uses the enhanced token passing protocol. TMC2084 I/O nodes are controlled by the Host node (TMC2074/72) via the network. Thus, TMC2084 enables a single-processor with multi-remote I/O controllers environment at reasonable cost.
The TMC2084 has thirty-two I/O port lines featuring programmable direction, with 8-bit basis (output: 16 to 32 bit; input: 0 to 16 bit). The maximum number of nodes per network is fifteen, including the host node. This configuration enables a processor to control a total of 448 (14 × 32) remote I/O lines. The Output Port type is selectable from either open-drain or push-pull, while one part of the I/O ports is definable as either output pins for network status monitoring, strobe output pins to handshake with AD or DA converter, or input pins for external trigger.
TMC2084 also has additional functions including the function to notify the host of its status, the states of its Output Ports and settings, the function to send packets with timestamp, and the function to synchronize the on-chip timer to the host.
This rich feature set is contained in a single 48-pin TQFP package.
