power supply circuit: TMS320-P28016 board can take power from power connector (4.5-6vac or 6-9vdc), from vin pin near to prototype area(5-9vdc), from motor connector pin 4 (5-9vdc) and from usb connector. the board power consumption is around 180 ma with all peripherals and mcu running at full speed. reset circuit: reset circuit is made with rc group r11 ? 1,5k and c25 ? 22nf. although on the schematic is made provision for external reset as mcp130t(sot23 package). manual reset is possible by the rst button. clock circuit: quartz crystal 20mhz is connected to tms320f28016. internal pll circuit can multiply this frequency up to 100mhz. jumper description: the jumpers gpio18, gpio29 and gpio34 selects boot mode source. the table bellow shows boot mode variants. default state. boot to m0 saram gpio34 10 gpio29 01 10 page 10

i2c: the inter-integrated circuit (i2c) module provides an interface between a dsp and other devices compliant with philips semiconductors inter-ic bus (i2c-bus) specification version 2.1 and connected by way of an i2c-bus. external components attached to this 2-wire serial bus can transmit/receive up to 8-bit data to/from the dsp through the i2c module. on the 280x, the i2c contains a 16-level receive and transmit fifo for reducing interrupt servicing overhead. can: this is the enhanced version of the can peripheral. it supports 32 mailboxes, time stamping of messages, and is can 2.0b-compliant. pin # signal name 1gnd 2canl 3canh jtag: ti standard 2x7 pin jtag connector pin # signal name pin # signal name 1 tms 2 #trst 3tdi 4gnd 5 5v/3.3v 6 nc 7tdo 810k to 3.3v 9tck 10gnd 11 tck 12 gnd 13 emu0 14 emu1 page 13
