Cmos 8-bit Microprocessor With On-chip Ram And Counter/timer Corporation

The CDP1805AC and CDP1806AC are functional and per- formance enhancements of the CDP1802 CMOS 8-bit regis- ter-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 enhance- ments 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 capabil- ity, enhanced data transfer manipulation, Counter Timer con- trol, 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.
