    Declaration regarding EMV-Conformity of the PHYTEC microMODUL-8051 PHYTEC Single Board Computers (henceforth products) are designed for installation in electrical appliances or as dedicated Evaluation Boards (i.e.: for use as a test and prototype platform for hardware/software development) in laboratory environments.
  • Page 6 PHYTEC supports all common 8- and 16-bit controllers in two ways: as the basis for Starter Kits in which user-designed hardware can be implemented on a wrap-field around the controller and as insert-ready, fully functional micro- and miniMODULS which can be embedded directly into the user’s peripheral...

  • Page 7: Introduction

    255 nodes in an ARCnet network. Precise specifications for the specific controller fitted on the microMODUL-8051 you have purchased can be found in the enclosed microcontroller manual. The microMODUL-8051 described herein is based on the standard 80C32 architecture. There follows no specific discussion of 80C32-derivative controllers, as the architecture of these derivatives is not relevant to the basic functioning of this module.
  • Page 8 The microMODUL-8051 offers the following features: • SBC in matchbox-size dimensions (51 x 36 mm) achieved through modern SMD technology • improved interference safety through multi-layer technology • controller signals and ports extend to standard-width (2.54 mm.) pins aligning board edges, allowing the board to be plugged into any target application like a “big chip”...

    3.2 Serial Interface J2, J3 With Jumpers J2 and J3 different signal levels and signal qualities can be applied to the serial interface pins of the microMODUL-8051 (Pins 35 and 36). These pins carry either the TTL-signals of the controller’s serial interface, the signals of the on-board RS-232 transceiver or the signals of the on-board RS-485 transceiver.
