  • Up to 14 general purpose Input/Output lines.
  • Up to 5 Analogue input channels with 10-bit A/D conversion.
  • 1 PWM output usable as an 8-bit D/A with a simple filter.
  • I2C address 0x40, can be changed to allow up to 8 devices on the same I2C bus.
  • 6 I/O lines have programmable pull-up resistors built into the chip .
  • Individual control of each pin for Input or Output.
  • Simple commands for Bit Set, Bit Clear and Bit Toggle.
  • Easy I2C bus control, similar protocol as popular EEPROM's such as 24C02.
