Introduction

The input part of the spreadsheet consists of the following sections: operating performance point, processor core utilization, LVCMOS IO, peripheral, estimated power, and general. Users must modify the input fields with appropriate usage parameters that represent the specific application use case. Cells designed for user input are in blue. Fields that cannot be modified are red. Fields in green are the output calculated power. Configure the blue cells to a value most closely aligned with your intended scenario.

Note: This tool does not have the complete set of IOs possible on the AM62L. Any IO configuration must be confirmed through the AM62L pinmux tool.

Purpose of each of each section:

  • Junction temperature: This section lets the user select the junction temperature (not ambient temperature) in Celsius (°C) up to 125°C.
  • Process corner: Typ or Max (‘Typ’ is the typical power consumption of most devices. ‘Max’ is the worst-case possible due to silicon variation).
  • Processor cores : Allows to configure the A53 frequency of operation and user estimated percentage of computational utilization for each core.
  • LVCMOS IO: Subset of commonly used IO with selectable mode and percent utilization.
  • Peripherals: Other peripherals with selectable mode and percent utilization.
  • Estimated power: Power estimation itemized by supply group. Power supply consolidation/groups rails are aligned with EVM design.
