Description
M320C25 is a digital signal processor with separate data
and program memory, both of which may be up to 64k
words. It has a 16-bit shifter, a 16 X 16 bit parallel multi-
plier and a 32-bit ALU/accumulator. Instructions are
pipelined and it can perform single-cycle multiply/accu-
mulate instructions. It contains a 16-bit timer, eight
auxiliary registers, an eight-level hardware stack, sixteen
input and sixteen output channels, and a serial port. It is
fully compatible, including instructions execution times,
with industry standard devices.
The M32C25 contains no RAM or ROM but provides
functional interconnect signals for connecting to memory
blocks. If internal program memory is required, a single
port RAM (or ROM) block of up to 4k X 16 may be con-
nected to the M320C25 (also the 256 X 16 internal data
RAM block 0 may be configured as program memory). If
internal data memory is required 1,2 or 3 blocks of dual-
port RAM may be connected to the M320C25. Block 0
and 1 can be up to 256 X 16 and block 2 up to 32 X 16.
