GENERAL DESCRIPTION
The DS80C310 is a fast 80C31/80C32-compatible
microcontroller. It features a redesigned processor
core without wasted clock and memory cycles. As a
result, it executes every 8051 instruction between 1.5x
and 3x faster than the original architecture for the
same crystal speed. Typical applications have a speed
improvement of 2.5x using the same code and the
same crystal. The DS80C310 offers a 25MHz
maximum
crystal
speed,
resulting
in
apparent
execution speeds of 62.5MHz (approximately 2.5x).
The DS80C310 is pin compatible with the standard
80C32 and includes standard resources such as three
timer/counters, 256 bytes of RAM, and a serial port. It
also provides dual data pointers (DPTRs) to speed
block data memory moves. It also can adjust the speed
of MOVX data memory access between two and nine
machine cycles for flexibility in selecting external
memory and peripherals. The DS80C310 offers
upward compatibility with the DS80C320.
