The 8XC196KB is a 16-bit microcontroller available in three different memory varieties ROMless (80C196KB)
8K ROM (83C196KB) and 8K OTP (One Time Programmable 87C196KB) The 8XC196KB is a high perform-
ance member of the MCS
8096BH and has a true superset of the 8096BH instructions Intel’s CHMOS process provides a high perform-
ance processor along with low power consumption To further reduce power requirements the processor can
be placed into Idle or Powerdown Mode
Bit byte word and some 32-bit operations are available on the 80C196KB With a 16 MHz oscillator a 16-bit
addition takes 0 50 s and the instruction times average 0 37 s to 1 1 s in typical applications
Four high-speed capture inputs are provided to record times when events occur Six high-speed outputs are
available for pulse or waveform generation The high-speed output can also generate four software timers or
start an A D conversion Events can be based on the timer or up down counter Also provided on-chip are an
A D converter serial port watchdog timer and a pulse-width-modulated output signal
The 8XC196KB has a maximum guaranteed frequency of 12 MHz The 8XC196KB16 has a maximum guaran-
teed frequency of 16 MHz All references to the 80C196KB also refer to the 80C196KB16 83C196KB Rxxx
87C196KB and 87C196KB16 unless otherwise noted The ROM device does not have a speed indicator at the
end of the device name Instead it has a ROM code number
With the commercial (standard) temperature option operational characteristics are guaranteed over the tem-
perature range of 0 C to
guaranteed over the temperature range of
