CDP1805AC, CDP1806AC
CMOS 8-Bit Microprocessor with On-Chip RAM† and Counter/Timer
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 64byte 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.
