Emulator Features
Introduction
EMULATOR FEATURES
Key features of the Z86L9900100ZEM ICEBOX include:
• Supports up to 32K of ROM
• Vary the operating voltage from 3.0-4.0V
• Supports in-circuit emulation on target systems that operate from 3.0-4.0V
• The user can choose to power the ICE chip from either the emulator or target board
• Supports IR devices that operate up to 8MHz
• Emulates 28 and 40-pin DIP and 28-pin SOIC
• OTP programming for 28 pin DIP and 28 pin SOIC, 40 pin DIP packages
• Emulates and supports all the features and functions for a specified Z8 IR
microcontroller
• Multitasking allows the user to use other Windows applications while ZiLOG
Developer Studio (ZDS) is running
EMULATOR LIMITATIONS
The Z86D99 ICE chip’s ROM/ROMLESS pin is used to configure the ICE CHIP for 32K of
internal ROM. This configuration affects the Z86L9900100ZEM ICEBOX in the following
ways:
• Will not support emulation of a ROMLESS operation mode
• 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
To emulate pull-up transistors for their target board, you must manually set the emulator’s
pull-up resistor dip switches. See page 2-12 for the proper settings of the emulator’s dip
switches.
NOTE: Mask option pull-up resistance at 3V is about 200k Ohm +/-50% at room temperature. Lower
voltage may cause an increase in resistance.
