DESCRIPTION
The IA8044/IA8344 is a form, fit and function compatible part to the Intel
8X44 SDLC
communications controller. The IA8044/IA8344 is a Fast Single-Chip 8-Bit Microcontroller with an
integrated SDLC/HDLC serial interface controller. The IA8044/IA8344 is a fully functional 8-Bit
Embedded Controller that executes all ASM51 instructions and has the same instruction set as the
Intel 80C51. The IA8044/IA8344 can access the instructions from two types of program memory,
serves software and hardware interrupts, provides an interface for serial communications and a timer
system. The IA8044/IA8344 is fully compatible with the Intel
8X44 series
.
