8XC196KB TO 8XC196KC DESIGN
CONSIDERATIONS
1 Memory Map The 8XC196KC has 512 bytes of
2 The CDE pin on the KB has become a V
3 EPROM programming The 8XC196KC has a dif-
RAM SFRs
ROM OTPROM The extra 256 bytes of RAM will
reside in locations 100H – 1FFH and the extra 8K
of ROM OTPROM will reside in locations
4000H – 5FFFH These locations are external
memory on the 8XC196KB
the KC to support 16 20 MHz operation
ferent programming algorithm to support 16K of
on-board memory When performing Run-Time
Programming use the section of code in the

1 Missed EXTINT on P0 7
2 HSI MODE divide-by-eight
3 IPD hump
on the 8XC196KC by driving the TXD pin low on
the rising edge of RESET The TXD pin is held
high by a pullup that is specified by I
Pullup must not be overridden or the 8XC196KC
will enter the ONCE mode
weakly holds RD WR ALE BHE and INST in
their inactive states The 8XC196KB only holds
ALE in its inactive state
rather than 4 states as on the 8XC196KB (i e a
watchdog timer overflow) This provides a longer
RESET pulse for other devices in the system
The 80C196KC20 could possibly miss an
EXTINT on P0 7 See techbit MC0893
