# SPIFlash

## Parameters

<ParamField path="memory_size" type="byte" />

## Interfaces

<ParamField path="power" type="ElectricPower" />

<ParamField path="qspi" type="MultiSPI" />

## 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>

<RequestExample>
  ```ato Basic Usage theme={null}
  import SPIFlash, ElectricPower, ElectricLogic

  spi_flash = new SPIFlash
  spi_flash.memory_size = 16MB  # Common sizes: 1MB, 2MB, 4MB, 8MB, 16MB, 32MB

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

  # Connect SPI/QSPI interface
  microcontroller.qspi ~ spi_flash.qspi

  # For standard SPI (using only 2 data lines)
  microcontroller.spi.sclk ~ spi_flash.qspi.sclk
  microcontroller.spi.mosi ~ spi_flash.qspi.ios[0]  # DI/IO0
  microcontroller.spi.miso ~ spi_flash.qspi.ios[1]  # DO/IO1

  # Chip select
  chip_select = new ElectricLogic
  chip_select.reference ~ power_3v3
  microcontroller.gpio_cs ~ chip_select.line
  spi_flash.qspi.cs ~ chip_select

  # For Quad SPI (4x faster)
  # microcontroller.qspi.ios[2] ~ spi_flash.qspi.ios[2]  # WP/IO2
  # microcontroller.qspi.ios[3] ~ spi_flash.qspi.ios[3]  # HOLD/IO3

  # Common applications: firmware storage, data logging, file systems
  ```
