IA6805E2 Datasheet | InnovASIC

IA6805E2 Microprocessor Unit Features Preliminary Data Sheet - Form, Fit, and Function patible 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. innov ASIC produces replacement ICs using its MILESTM, or Managed IC Lifetime Extension System, cloning technology. This technology produces replacement ICs far more plex than "emulation" while ensuring they are patible 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.
