13 1768ms?atarm?09-jul-09 AT91RM9200 5. power considerations 5.1 power supplies the AT91RM9200 has five types of power supply pins: ? vddcore pins. they power the core, including processor, memories and peripherals; voltage ranges from 1.65v to 1.95v, 1.8v nominal. ? vddiom pins. they power the external bus interface i/o lines; voltage ranges from 3.0v to 3.6v, 3v or 3.3v nominal. ? vddiop pins. they power the peripheral i/o lines and the usb transceivers; voltage ranges from 3.0v to 3.6v, 3v or 3.3v nominal. ? vddpll pins. they power the pll cells; voltage ranges from 1.65v to 1.95v, 1.8v nominal. ? vddosc pin. they power both oscillators; vo ltage ranges from 1.65v to 1.95v, 1.8v nominal. the double power supplies vddiom and vddiop are identified in table 4-1 on page 9 and table 4-2 on page 11 . these supplies enable the user to power the device differently for inter- facing with memories and for interfacing with peripherals. ground pins are common to all power supplies, except vddpll and vddosc pins. for these pins, gndpll and gndosc are provided, respectively. 5.2 power consumption the AT91RM9200 consumes about 500 a of static current on vddcore at 25 ? c. for dynamic power consumption, the AT91RM9200 consumes a maximum of 25 ma on vddcore at maximum speed in typical conditions (1.8v, 25 ? c), processor running full-performance algorithm. 6. i/o considerations 6.1 jtag port pins tms and tdi are schmitt trigger inputs and integrate internal pull-up resistors of 15 kohm typi- cal. tck is a schmitt trigger inpu t without internal pull-up resistor. tdo is a tri-state output. the jtagsel pin is used to select the jtag boundary scan when asserted at a high level. the ntrst pin is used to initialize the embeddedice ? tap controller. 6.2 test pin the tst0 and tst1 pins are used for manufacturing test purposes when asserted high. as they do not integrate a pull-down resistor, they must be tied low during normal operations. driving this line at a high level leads to unpredictable results. 6.3 reset pin nrst is a schmitt trigger without pull-up resist or. the nrst signal is inserted in the boundary scan.
14 1768ms?atarm?09-jul-09 AT91RM9200 6.4 pio controller a, b, c and d lines all the i/o lines pa0 to pa31, pb0 to pb29, pc0 to pc31 and pd0 to pd27 integrate a program- mable pull-up resistor of 15 kohm typical. programming of this pull-up resistor is performed independently for each i/o line through the pio controllers. after reset, all the i/o lines default as inputs wi th pull-up resistors enabled, except those which are multiplexed with the external bus interface signals that must be enabled as peripherals at reset. this is explicitly indicated in the column "reset state" of the pio controller multiplexing tables. 7. processor and architecture 7.1 arm920t processor ? arm9tdmi ? -based on arm architecture v4t ? two instruction sets ? arm high-performance 32-bit instruction set ? thumb high code density 16-bit instruction set ? 5-stage pipeline architecture: ? instruction fetch (f) ? instruction decode (d) ? execute (e) ? data memory (m) ? register write (w) ? 16-kbyte data cache, 16- kbyte instruction cache ? virtually-addressed 64-way associative cache ? 8 words per line ? write-though and write-back operation ? pseudo-random or round-robin replacement ? low-power cam ram implementation ? write buffer ? 16-word data buffer ? 4-address address buffer ? software control drain ? standard armv4 memory management unit (mmu) ? access permission for sections ? access permission for large pages and small pages can be specified separately for each quarter of the pages ? 16 embedded domains ? 64 entry instruction tlb and 64 entry data tlb 8-, 16-, 32-bit data bus for instructions and data 7.2 debug and test ? integrated embeddedice

18 1768ms?atarm?09-jul-09 AT91RM9200 a first level of address decoding is performed by the memory controller, i.e., by the implementa- tion of the advanced sy stem bus (asb) with ad ditional features. decoding splits the 4g bytes of address space into 16 areas of 256m bytes. the areas 1 to 8 are directed to the ebi that associates these areas to the external chip selects nc0 to ncs7. the area 0 is reserved for the addressing of the internal memories, and a second level of decoding provides 1m bytes of internal memory area. the area 15 is reserved for the peripherals and pro- vides access to the advanced peripheral bus (apb). other areas are unused and performing an access within them provides an abort to the master requesting such an access. 8.1 embedded memories 8.1.1 internal memory mapping 8.1.1.1 internal ram the AT91RM9200 integrates a high-speed, 16-kbyte internal sram. after reset and until the remap command is performed, the sram is only accessible at address 0x20 0000. after remap, the sram is also available at address 0x0. 8.1.1.2 internal rom the AT91RM9200 integrates a 128-kbyte internal rom. at any time, the rom is mapped at address 0x10 0000. it is also accessible at address 0x0 after reset and before the remap com- mand if the bms is tied high during reset. 8.1.1.3 usb host port the AT91RM9200 integrates a usb host port open host controller interface (ohci). the reg- isters of this interface are directly acce ssible on the asb bus and are mapped like a standard internal memory at address 0x30 0000.
