Introduction
The Innovasic Semiconductor IA8044 and IA8344 are ―plug-and-play‖ drop-in replacements and are form, fit, and function compatible parts to the Intel 8044 and 8344 (see Chapter 4, Innovasic/Intel Part Number Cross-Reference Tables). These devices are produced using Innovasic’s Managed IC Lifetime Extension System (MILES™). This cloning technology, which produces replacement ICs beyond simple emulations, ensures complete compatibility with the original device, including any ―undocumented features.‖ Additionally, the MILES™ process captures the clone design in such a way that production of the clone can continue even as silicon technology advances. The IA8044 and IA8344 replace the obsolete Intel 8044 and 8344, allowing users to retain existing board designs, software compilers/assemblers, and emulation tools—thus avoiding expensive redesign efforts.
The IA8044 and IA8344 are Fast Single-Chip 8-Bit Microcontrollers with an integrated SDLC/HDLC serial interface controller. They are fully functional 8-Bit Embedded Controllers that execute all ASM51 instructions and have the same instruction set as the Intel 80C51. The IA8044 and IA8344 can access the instructions from two types of program memory, serve software and hardware interrupts, and provide interface for serial communications and a timer system. The IA8044 and IA8344 are fully compatible with the Intel 8X44 series.
