Micro-controller MINI-MAX/51-C2 has an ATMEL AT89C51ED2 micro-controller (U2). Micro-controller ports and power lines are provided on a 20-pin expansion bus for interfacing to peripherals and other external circuits. AT89C51ED2 has 4 ports that are available on the 8051 family of micro-controllers: P0 … P3. - Page 6 PC for In-circuit Programming of the T89C51ED2 through PIC16F818 microcontroller and by T89C51ED2 for data communications. RTS line is used by an external host such as a PC to put MINI-MAX/51-C2 in program or run mode. Therefore, user applications must not use RTS.
- Page 7 A peripheral board can be connected to MINI-MAX/51-C2 either as a piggyback daughter-board using standoffs or can be placed away from the MINI-MAX/51-C2 board using a 20-wire ribbon cable ( Part #: EXPCABLE-6 ). Table 4 shows the pin assignments for the connector.
- Page 8 CAUTION: Depending on the current requirements of the any external circuitry such as peripheral boards that are attached to MINI-MAX/51-C2 and the level of input voltage applied, the power regulator U1 may dissipate enough heat to cause skin injury upon touch. Contact with this regulator should be...
