The meaning of the table entries is:
chip number: | the number that identifies the chip |
case: | the housing of the chip. DIL is the large case for "through-hole" insertion, SO is small-outline for SMD technology |
analog detection: | if yes, the loco automatically behaves like a conventional loco on analog track |
signal inversion: | exchange of red/brown track connection so that signal is inverted |
signal format: | can be either Motorola 1 or Motorola 2. In Motorola 1 only aux. function, speed, or direction change can be signalled. In Motorola 2, additionally direction and f1 - f4 can be signalled |
aux. function f0: | the auxiliary function, usually used for direction dependent head light. "protected" means that the driving transistor and overload and short circuit protection are built into the chip |
ext. functions f1 - f4: | extended functions f1 - f4, only possible in Motorola 2 mode |
internal motor driver: | if yes the motor driving stage is built into the chip and no external circuitry is required. |
internal motor control: | if yes the motor control to achieve constant speed is built into the chip |
internal accel./decel.: | if yes the motor acceleration and deceleration is built into the chip |
speed levels: | 14 or 27. By coincidence, chips understanding Motorola 2 provide 27 speed steps. |
reverse lock: | if yes, at speeds above 6 (of the range 1 - 14) a direction change signalled in Motorola 1 is ignored. |
use: | the decoders where this chip has been used |
