Description:Intel 8051 and 8031 are members of Intel MCS-51
family of 8-bit microcontrollers. In addition to
on-chip clock oscillator, 2 16-bit timers, 4 I/O
ports and a serial port, all 8051 and 80C51 chips
have 128 bytes of RAM and 4 KB masked ROM. If
necessary, 8051 memory can be expanded up to 128
KB by adding up to 64 KB of external program and
data memory.
-----------
8031 - No ROM
8051 - Normal 8051
8751 - Onboard EPROM
8052 - COntrol Oreinted 8051
-------------------------------
This is the In-Circuit Emulator for the 8051.
It has much more capabledebugging then a plain
8051 which is useful in developing a system.
