MOS Technology 6532
 |
The 6532 RAM-I/O-Timer (RIOT) was an integrated circuit made by
8-bit digital input/output ports, and a Programmable interval timer. This high degree of integration made it quite popular in the late 1970s and early 1980s, as it could take the place of several different integrated circuits
(ICs).
Perhaps its best-known application was the
Atari 400 and 800 computers an RS-232
interface, used two 6532 chips. The CPU board for Pizza Time Theatre’s Cyberamics control system also used two 6532 chips.
6532 ICs were available in 1
(ceramic or plastic).External links
