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.

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.

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-
