COP8-PGMA-DS NSC [National Semiconductor], COP8-PGMA-DS Datasheet - Page 5

• Manufacturer Part Number: COP8-PGMA-DS
• Description: 8-Bit One-Time Programmable (OTP) Microcontroller with UART and Three Multi-Function Timers
• Manufacturer: NSC [National Semiconductor]

AC Electrical Characteristics COP888KG
Note 1 Maximum rate of voltage change must be less than 0 5 V 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 Measurement of IDD HALT is done with device neither sourcing or
sinking current with L C and G0–G5 programmed as low outputs and not driving a load all outputs programmed low and not driving a load all inputs tied to V
clock monitor and comparators disabled Parameter refers to HALT mode entered via setting bit 7 of the G Port data register Part will pull up CKI during HALT in
crystal clock mode
Note 4 Pins G6 and RESET are designed with a high voltage input network These pins allow input voltages greater than V
V
(typical) These two pins will not latch up The voltage at the pins must be limited to less than 14V WARNING Voltages in excess of 14V will cause damage to
the pins This warning excludes ESD transients
