CDP1805AC General Description
The 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 CDP1805AC 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 timebase, event-counting, and pulse-duration measurement applications. The Counter/Timer underflow output can also be directed to the Q output terminal. The CDP1806AC hardware enhancements are identical to the CDP1805AC, except the CDP1806AC contains no on-chip RAM.
The CDP1805AC and CDP1806AC software enhancements include 32 more instructions than 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 CDP1805AC or CDP1806AC for other CDP1800-series microprocessors. Pinout is identical except for the replacement of VCC with ME on the CDP1805AC and the replacement of VCC with VDD on the CDP1806AC.
