Z86L98 ZEM
Z8 In-Circuit Emulator

General Description
ZiLOG's in-circuit emulators are interactive, Windows-oriented development tools,
providing a real-time environment for emulation and debugging.
The Z86L98 emulator (Z86L9800ZEM) is a member of ZiLOG's ICEBOXª
product family of in-circuit emulators. The emulator provides essential timing and
I/O circuitry to simplify user emulation of prototype hardware and software
products.
The Z86L98 emulator provides users with a hardware platform to develop and
debug software in a real-time environment. In contrast, software simulators area
significantly slower making them less practical for code development.
The Z86L98 emulator can be connected to any serial port (COM1, COM2, COM3,
and COM4) on the host computer. ZiLOG Developer Studio (ZDS) software
initiates the interaction between the host computer and the emulator.
Notes/Limitations
The ROM/ROMLESS pin is used to configure the Z86D93ICE chip for either 32K
or 64K internal ROM. This configuration affects the Z86L9800ZEM in the following
ways:
• Does not support emulation of a ROMLESS operation
• If the host software specifies that a device has between 4K to 32K of ROM,
the emulator operates as if it is emulating a device with 32K of ROM.
• If the host software specifies that a device has more than 32K of ROM, the
emulator operates as if it is emulating a device with 64K of ROM.
Mask option pull-up resistance at 3V is approximately 200kΩ ±
50% at room temperature. Lower voltage can cause increased
resistance.
