Summary
[edit]
| Description |
Vintage Motorola MC68705 8-bit microcontroller. Confusing the on-chip A/D converter with a flashlight. This light sensitivity is not intended. Many ICs would react to light and thus they are encapsulated in black plastic. The uC even gets stuck by erratic currents caused by the flashlight and needs a reset. It is vintage NMOS technology, it draws 100mA supply current for doing nothing! (power-saving CMOS technology already existed these times, but it could not reach the MHz speed range yet). |
