Power Supply Diagram JACK SCHOTTKY LM317T 100NF 10MF-CT-16V GND POWER 10K-RV 2.2.2 Reset Circuit A reset circuit located on the motherboard (R1, D1 and C2) is used to guarantee that the reset pin is pulled LOW until the voltage supply is stabilized at the correct level. A push-button switch (SW2) is provided to manually reset the device (MCU or emulator) being evaluated. -
Page 7: Connector Layout
EVALUATION BOARD GETTING STARTED 2.2.3 Connector Layout Most of the MCU pins can be monitored or controlled by using the connectors located on the motherboard. Connectors are directly linked to parallel I/O ports P0, P1, P4, P5, P6 and P7, as well as to 3 other ports connected to PA, PB and PC. -
Page 8: Memories
512-Kbyte single-supply FLASH memory. The datasheets for these devices are available on the on ST web site, www.st.com. Ports P0, P1 and PC are used for addressing the various memories. The microcontroller addresses the devices using the 6 most significant bits (PC) of the 22 addresses which may be set automatically or manually via the I/O port. -
Page 9: I²C Interface
EVALUATION BOARD GETTING STARTED – EPROM: segments 0x00 and 0x01. – Flash: segments 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E and 0x0F. – RAM: segments, 0x24 and 0x25. For segment definitions, refer to any ST9 datasheet. The comparator (74HC688) is used to select the memories. When the ST92F150-TQFP64 daughter board is used, the 5 Most Significant Address Bits A[15:11] must be connected di- rectly on the board to a High or a Low level by hardware as port P1 is limited to P1[2:0]. -
