GENERAL DESCRIPTION
The Z80382 (Z382) is designed to address high-end data
communication applications such as digital modems (IS-
DN, GSM, Mobitex & Modacom), xDSL and analog mo-
dems (V.34 and beyond). The Z382 provides a perfor-
mance upgrade to existing Z80- and Z18x-based designs
by utilizing the increased bandwidth of the 380C proces-
sor. The Z8L382 is a low voltage version of the device.
Note:
In this document the notation Ò380CÓ denotes the
Z380-compatible CPU core which is embedded in the
Z382.
The 380C microprocessor is a high-performance proces-
sor with fast and efficient throughput and increased mem-
ory addressing capabilities. The 380C offers a continuing
growth path for present Z80- or Z18x-based designs, while
maintaining Z80 and Z180 object code compatibility. Its en-
hancements include added instructions, expanded16 MB
address space and flexible bus interface timing.
In the 380C, the basic addressing modes of the Z80 micro-
processor have been augmented to include Stack Pointer
Relative loads and stores, 16-bit and 24-bit indexed off-
sets, and more flexible Indirect Register addressing. Inter-
nally, all of the addressing modes allow up to 32-bit linear
addressing; however, because the Z382 has only 24 ad-
dress pins, it can only address 16 MB of memory.
