Power Considerations
Power Supplies
AT91SAM9261 types power supply pins: VDDCORE pins: Power core, including processor, memories peripherals; voltage ranges from 1.08V 1.32V, 1.2V nominal. VDDIOM pins: Power External Interface lines; voltage ranges from 1.65V 1.95V 3.0V 3.6V, 1.8V 3.3V nominal. VDDIOP pins: Power Peripheral lines transceivers; voltage ranges from 2.7V 3.6V, 3.3V nominal. VDDBU pin: Powers Slow Clock oscillator part System Controller; voltage ranges from 1.08V 1.32V, 1.2V nominal. VDDPLL pin: Powers cells; voltage ranges from 3.0V 3.6V, 3.3V nominal. VDDOSC pin: Powers Main Oscillator cells; voltage ranges from 3.0V 3.6V, 3.3V nominal. double power supplies VDDIOM VDDIOP identified Table page These supplies enable user power device differently interfacing with memories interfacing with peripherals. Ground pins common VDDCORE, VDDIOM VDDIOP pins power supplies. Separated ground pins provided VDDBU, VDDOSC VDDPLL. ground pins GNDBU, GNDOSC GNDPLL, respectively.
Power Consumption
AT91SAM9261 consumes about static current VDDCORE 25°C. This static current rises temperature increases 85°C. VDDBU, current does exceed @25°C, rise @85°C. dynamic power consumption, AT91SAM9261 consumes maximum VDDCORE maximum speed typical conditions (1.2V, 25°C), processor running full-performance algorithm.
Line Considerations
JTAG Port Pins
TMS, Schmitt trigger inputs have pull-up resistors. RTCK outputs, driven VDDIOP, have pull-up resistor. JTAGSEL used select JTAG boundary scan when asserted high level (tied VDDBU). integrates permanent pull-down resistor about GNDBU, that left unconnected normal operations. NTRST used initialize embedded Controller when asserted level. integrates permanent pull-up resistor about VDDIOP, that left unconnected normal operations.
6062GS-ATARM-05-Dec-06
Test
used manufacturing test purposes when asserted high. integrates permanent pull-down resistor about GNDBU, that left unconnected normal operations. Driving this line high level leads unpredictable results.
Reset
NRST open-drain output integrating non-programmable pull-up resistor. driven with voltage VDDIOP. product integrates power-on reset cells, NRST left unconnected case reset from system needs applied product. NRST integrates permanent pull-up resistor minimum VDDIOP. NRST signal inserted Boundary Scan.
Controller Lines
lines PA31, PB31, PC31 integrate programmable pull-up resistor Programming this pull-up resistor performed independently each line through Controllers. After reset, lines default inputs with pull-up resistors enabled, except those which multiplexed with External Interface signals that require enabled Peripherals reset. This explicitly indicated column "Reset State" Controller multiplexing tables.
Shutdown Logic Pins
SHDN output only, driven Shutdown Controller. WKUP input only. accept voltages only between VDDBU.

first level address decoding performed Matrix, i.e., implementation Advanced High performance (AHB) Master Slave interfaces with additional features. Decoding breaks Gbytes address space into areas Mbytes. areas directed that associates these areas external chip selects NCS0 NCS7. area reserved addressing internal memories, second level decoding provides Mbyte internal memory area. area reserved peripherals provides access Advanced Peripheral (APB). Other areas unused performing access within them provides abort master requesting such access. Matrix manages five Masters five Slaves.

Peripheral Multiplexing Lines
AT91SAM9261 features three controllers, PIOA, PIOB PIOC, that multiplex lines peripheral set. Each Controller controls thirty-two lines. Each line assigned peripheral functions, Table 10-2 page Table 10-3 page Table 10-4 page define lines peripherals multiplexed Controllers. columns "Function" "Comments" have been inserted user's comments; they used track pins defined application. Note that some output only peripheral functions might duplicated within tables.

column "Reset State" indicates whether line resets mode peripheral mode. mentioned, line resets input with pull-up enabled, that device maintained static state soon reset released. result, corresponding line register PIO_PSR (Peripheral Status Register) resets low. signal name mentioned "Reset State" column, line assigned this function corresponding PIO_PSR resets high. This case pins controlling memories, particular address lines, which require driven soon reset released. Note that pull-up resistor also enabled this case. 10.3.1 10.3.1.1 Resource Multiplexing Controller Controller interface with several panels. supports bit-per-pixel without limitation.
