Product Summary

The AT80C32X2-SLSUM is a high performance CMOS single chip 8-bit microcontroller. The AT80C32X2-SLSUM retains all features of the 80C51 with extended ROM/EPROM capacity (8 Kbytes), 256 bytes of internal RAM, a 6-source, 4-level interrupt system, an on-chip oscilator and three timer/counters. In addition, the AT80C32X2-SLSUM has a dual data pointer, a more versatile serial channel that facilitates multiprocessor communication (EUART) and an X2 speed improvement mechanism.
