GENERAL DESCRIPTION

IC89E54, IC89E58, IC89E64 are members of ICSI embedded microcontroller family. The IC89E54/58/64 uses the same powerful instruction set, has the same architecture, and is pin-to-pin compatible with standard 80C51 controller devices. They have IC89E54/58/64 all functions and some enhanced function is included. These enhanced functions include 512 bytes auxiliary memory, 36 I/O pins (44 pin package only), 8 interrupts (44 pin package only) with two level priority, Power off flag, Low EMI mode, power down mode is waken up from interrupt level trigger mode.
