The ThinkPad Embedded Controller

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

  • Renesas H8
  • T20: H8/3437 ; 64F3437TF16 JAPAN (sticker label 08K3766 REV 11)
  • Renesas H8S
Apparently H8S microcontrollers have been used on all ThinkPads since the A30, T23, R40, X20.
  • Microchip MEC1633
The Microchip MEC1633-series Embedded Controllers can be found in newer ThinkPads, including the following:
  • 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.
