C511 / C513

Semiconductor Group

AC Characteristics (applies to all C511/513 Family Microcontrollers)

CC = 5 V + 10 %, – 15 %; VSS = 0 V

A = 0 ˚C to + 70 ˚C

(

L for port 0, ALE and PSEN outputs = 100 pF; CL for all other outputs = 80 pF)

Program Memory Characteristics

*) Interfacing the C511/513 microcontrollers to devices with float times up to 75 ns is permissible. This limited

bus contention will not cause any damage to port 0 drivers.
