The ThinkPad Embedded Controller

This page contains information about Embedded Controller (also known as slave controller) chips found in ThinkPads.

Apparently H8S microcontrollers have been used on all ThinkPads since the A30, T23, R40, X20.
  • T500: Renesas H8S/2116V
  • Unknown chips with field-upgradeable firmware
Used on older ThinkPads, including the model 570, and maybe even earlier models. IBM called them Slave Controllers.
  • Unknown chips with non-field-upgradeable firmware
Used on ancient ThinkPads.
