fabricated using double-metal silicon gate
microCMOS technology This low cost microcontroller is a
complete microcomputer containing all system timing inter-
rupt logic ROM RAM and I O necessary to implement
dedicated control functions in a variety of applications Fea-
tures include an 8-bit memory mapped architecture MI-

DC Electrical Characteristics
(Continued)
Note 1
Rate of voltage change must be less than 0 5V ms
Note 2
Supply current is measured after running 2000 cycles with a square wave CKI input CKO open inputs at rails and outputs open
Note 3
The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations Test conditions All inputs tied to V
CC
L C and G ports TRI-STATE
and tied to ground all outputs low and tied to ground
Note 4
Pins G6 and RESET are designed with a high voltage input network for factory testing These pins allow input voltages greater than V
CC
and the pins will
have sink current to V
CC
when biased at voltages greater than V
CC
(the pins do not have source current when biased at a voltage below V
CC
) The effective
resistance to V
CC
is 750X (typ) These two pins will not latch up The voltage at the pins must be limited to less than 14V
Note 5
To maintain RAM integrity the voltage must not be dropped or raised instantaneously
