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 V_CC, 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 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 750Ω (typical). These two pins will not latch up. The voltage at the
pins must be limited to less than 14V.
