# ResistorArray

## Init Args

<ParamField path="resistor_count" type="int" />

## Parameters

<ParamField path="rated_power" type="watt" />

<ParamField path="rated_voltage" type="volt" />

<ParamField path="resistance" type="ohm" />

## Global Attributes

These attributes are available to all modules and interfaces in a design.

<ParamField path="lcsc_id" type="str">
  Assign the LCSC ID of the module.

  If set, this will tell the picker to select that part from LCSC for this block.
</ParamField>

<ParamField path="manufacturer" type="str">
  This module's manufacturer name, as a string.

  Only exact matches on the manufacturer's name will be found by the picker.
  It's recommended to fill this information based on what `ato create component`
  provides.
</ParamField>

<ParamField path="mpn" type="str">
  This module's manufacturer part number, as a string.

  For the picker to select the correct part from the manufacturer,
  this must be set.
</ParamField>

<ParamField path="package" type="str">
  The package of the module.

  This drives which components can be selected, and what footprint is used.

  Must exactly match a known package name.
</ParamField>

<ParamField path="exclude_from_bom" type="bool" />

<ParamField path="override_net_name" type="str">
  When set on an interface, this will override the net name of the interface.

  This is useful for renaming nets which are automatically generated.
</ParamField>

<ParamField path="required" type="bool">
  Only for ModuleInterfaces.
  If set to `True`, require that interface is connected to something outside
  of the module it's defined in.
</ParamField>

  ```ato Basic Usage theme={null}
  import ResistorArray, ElectricPower, ElectricLogic

  # Create 8-resistor array for pull-ups
  pullup_array = new ResistorArray(resistor_count=8)
  pullup_array.resistance = 10kohm +/- 5%
  pullup_array.rated_power = 125mW
  pullup_array.rated_voltage = 50V
  pullup_array.package = "4816"  # 8-pin SIP package

  # Connect power supply
  power_3v3 = new ElectricPower
  assert power_3v3.voltage within 3.3V +/- 5%

  # Use for GPIO pull-ups
  gpio_signals = new ElectricLogic[8]
  for i in range(8):
      gpio_signals[i].reference ~ power_3v3
      gpio_signals[i].line ~> pullup_array.resistors[i] ~> power_3v3.hv
      microcontroller.gpio[i] ~ gpio_signals[i].line

  # Alternative: 4-resistor array for I2C/SPI bus termination
  termination_array = new ResistorArray(resistor_count=4)
  termination_array.resistance = 33ohm +/- 1%
  termination_array.package = "4806"  # 4-pin array

  # Common applications: pull-up/pull-down networks, bus termination,
  # voltage dividers, current limiting, LED drivers
