Pin Functions

PIN I/O TYPE DESCRIPTION
NO. NAME
1 INT_IN Input Digital Interrupt input pin. An active low input that extends the INT_IN signal to the INT output of the AMC80.
2 SDA I/O Digital Serial bus data line for SMBus, open-drain; requires pull-up resistor.
3 SCL I/O Digital Serial bus clock line for SMBus, open-drain; requires pull-up resistor.
4 FAN1 Input Digital Fan tachometer input pin
5 FAN2 Input Digital Fan tachometer input pin
6 BTI Input Digital Board temperature interrupt pin. BTI is driven by the over-temperature shutdown (OS) outputs of the additional temperature sensors. This pin has an internal 10-kΩ pull-up resistor.
7 GPI(CI) Input Digital General-purpose input pin (chassis interrupt). An active high interrupt input pin to latch a chassis interrupt event.
8 DGND Power Analog Digital ground.
9 V+ Power Analog Positive supply voltage (3V to 5.5V).
10 INT Output Digital Non-maskable interrupt (active high, PMOS, push-pull) or interrupt request (active low, NMOS, push-pull) pin. The INT pin becomes active when INT_IN, BTI, or GPI interrupts. This pin does not require a pullup resistor to V+.
11 GPO Output Digital General-purpose output pin. GPO is an active low, NMOS, open-drain output. This pin is intended to drive an external power PMOS for software power control or to control power to a cooling fan.
12 NTEST_IN/RESET_IN Input Digital This pin is an active-low input that enables NAND tree board-level connectivity testing. The AMC80 resets to its power-on state when NAND tree connectivity is enabled.
13 RST_OUT/OS Output Digital This pin is an NMOS open-drain output. RST_OUT provides a master reset to devices connected to this line. OS is dedicated to the temperature reading alarm.
14 AGND Power Analog Analog ground. This pin must be tied to a low-noise analog ground plane for optimum performance.
15 CH6 Input Analog Analog input channel 6
16 CH5 Input Analog Analog input channel 5
17 CH4 Input Analog Analog input channel 4
18 CH3 Input Analog Analog input channel 3
19 CH2 Input Analog Analog input channel 2
20 CH1 Input Analog Analog input channel 1
21 CH0 Input Analog Analog input channel 0
22 A0/NTEST_OUT I/O Digital The lowest order bit of the serial bus address. During a NAND tree test for ATE board-level connectivity, this pin functions as an output.
23 A1 Input Digital Address pin 1
24 A2 Input Digital Address pin 2
