Yoo FOR CDPIB06AC 92CS,35004
CDP1805AC, CDP1806AC
CMOS a-Bit Microprocessor With
On-Chip RAM" and Counter/Timer
Performance Features:
• Instruction time of 3.2 fJS,
-40 to +85°C
• 123 instructions - upwards software
compatible with CDP1802
• BCD arithmetic instructions
• Low-power IDLE mode
• Pin com{!atible with CDP1802
except for terminal 16
• 64K-byte memory address capability
• 64 bytes of on-chip RAM'"
• 16 x 16 matrix of on-board registers
• On-chip crystal or RC
controlled oscillator
• 8-bit Counter/Timer
",CDP1805AC only
The RCA-CDP1805AC and CDP1806AC are functional and
performance enhancements of the CDP1802 CMOS 8-bit
register-oriented microprocessor series and are designed
for use in general-purpose applications
The CDP180SAC hardware enhancements Include a 64-
byte RAM and an 8-bit presettable down counter. The
Counter/Timer which generates an internal interrupt
request, can be programmed for use in time-base, event-
counting, and pulse-duration measurement applications.
The Counter/Timer underflow output can also be directed
to the 0 output terminal. The CDP1806AC hardware
enhancements are identical to the CDP180SAC, except the
CDP1806AC contains no on-chip RAM.
The CDP180SAC and CDP1806AC are identical to the
CDP1804AC, except for the on-chip memory, and may be
used for CDP1804AC development purposes.
The CDP180SAC and CDP1806AC software enhancements
include 32 more instructions that the CDP1802. The 32 new
software instructions add subroutine call and return
capability, enhanced data transfer manipulation,
Counter/Timer control, improved interrupt handling,
single-instruction loop counting, and BCD arithmetic.
Upwards software and hardware compatibility is maintained
when substituting a CDP180fiAC or CDP1806AC for other
CDP1800-series microprocessors. Pinout is identical except
for the replacement of Vee with ME on the CDP180SAC and
the replacement of Vee with Voo on the CDP1806AC.
The CDP180SAC and CDP1806AC have an operating voltage
range of 4 V to 6.S V and are supplied in a 40-lead hermetic
dual-in-line ceramic package (0 suffix). 40-lead dual-in-
line plastic package (E suffix) and 44-lead plastic chip-
carrier (PCC) package (0 suffix).
