1 / 31 page IA6805E2 Data Sheet Microprocessor Unit As of Production Version 00 Copyright © 2002 ENG21108140100 www.innovasic.com innovASIC Customer Support: The End of Obsolescence ™ Page 1 of 31 1-888-824-4184 FEATURES • Form, Fit, and Function Compatible with the Harris© CDP6805E2CE and Motorola© MC146805E2 • Internal 8-bit Timer with 7-Bit Programmable Prescaler • On-chip Clock • Memory Mapped I/O • Versatile Interrupt Handling • True Bit Manipulation • Bit Test and Branch Instruction • Vectored Interrupts • Power-saving STOP and WAIT Modes • Fully Static Operation • 112 Bytes of RAM The IA6805E2 is a "plug-and-play" drop-in replacement for the original IC. innovASIC produces replacement ICs using its MILESTM, or Managed IC Lifetime Extension System, cloning technology. This technology produces replacement ICs far more complex than "emulation" while ensuring they are compatible with the original IC. MILESTM captures the design of a clone so it can be produced even as silicon technology advances. MILESTM also verifies the clone against the original IC so that even the "undocumented features" are duplicated. This data sheet documents all necessary engineering information about the IA6805E2 including functional and I/O descriptions, electrical characteristics, and applicable timing.
