Note 2: Rate of voltage change must be less than 0.5V/ms.
Note 3: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 4: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Test conditions: All inputs tied to VCC, L and G0 — G5 configured as
outputs and set high. The D port set to zero.
Note 5: Except pin G7: +100 mA, 25 mA (COP920C only). Sampled and not 100% tested. Pins G6 and RESET are designed with a high voltage input network for
factory testing. These pins allow input voltages greater than VCC and the pins will have sink current to VCC when biased at voltages greater than VCC (the pins do
not have source current when biased at a voltage below VCC). The effective resistance to VCC is 750 (typical). These two pins will not latch up. The voltage at the
pins must be limited to less than 14V.
