Z8L382

Stresses greater than those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; operation of the device at any condition above those indicated in the operational sections of these specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The Z80382 (Z382) is designed to address high-end data communication applications such as digital modems (ISDN, GSM, Mobitex & Modacom), xDSL and analog modems (V.34 and beyond). The Z382 provides a performance upgrade to existing Z80- and Z18x-based designs by utilizing the increased bandwidth of the 380C processor. 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 processor with fast and efficient throughput and increased memory 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 enhancements include added instructions, expanded16 MB address space and flexible bus interface timing.

In the 380C, the basic addressing modes of the Z80 microprocessor have been augmented to include Stack Pointer elative loads and stores, 16-bit and 24-bit indexed offsets, and more flexible Indirect Register addressing. Internally, all of the addressing modes allow up to 32-bit linear addressing; however, because the Z382 has only 24 address pins, it can only address 16 MB of memory.
