ATMEGA406 - 8-bit Microcontroller

General Description

VFET High voltage supply pin.

This pin is used as supply for the internal voltage regulator, described in ”Voltage Regulator” on page 114.

In addition the voltage level on this pin is monitored by the battery protection circuit, for deep-under-voltage protection.

Key Features

  • High Performance, Low Power AVR® 8-bit Microcontroller.
  • Advanced RISC Architecture.
  • 124 Powerful Instructions - Most Single Clock Cycle Execution.
  • 32 x 8 General Purpose Working Registers.
  • Fully Static Operation.
  • Up to 1 MIPS Throughput at 1 MHz Nonvolatile Program and Data Memories.
  • 40K Bytes of In-System Self-Programmable Flash, Endurance: 10,000 Write/Erase Cycles.
  • Optional Boot Code Section with Independent Lock Bits In.
