Preparation for
Delivery
Certificate of Compliance Atmel offers a certificate of compliance with each shipment of parts, affirming the prod-
ucts are in compliance with MIL-STD-883 and guaranteeing the parameters are tested
at extreme temperatures for the entire temperature range.
Handling
MOS devices must be handled with certain precautions to avoid damage due to accu-
mulation of static charge. Input protection devices have been designed in the chip to
minimize the effect of this static buildup. However, the following handling practices are
recommended:
a) Device should be handled on benches with conductive and grounded surface.
b) Ground test equipment, tools and operator
c) Do not handle devices by the leads.
d) Store devices in conductive foam or carriers.
e) Avoid use of plastic, rubber, or silk in MOS areas.
f) Maintain relative humidity above 50%, if practical.

Description
The TS68020 is the first full 32-bit implementation of the TS68000 family of microprocessors. Using HCMOS technology, the TS68020 is implemented with 32-bit registers and data paths, 32-bit addresses, a rich instruction set, and versatile addressing modes.

Features
• Object Code Compatible with Earlier TS68000 Microprocessors
• Addressing Mode Extensions for Enhanced Support of High Level Languages
• New Bit Field Data Type Accelerates Bit-oriented Application, i.e. Video Graphics
• Fast on-chip Instruction Cache Speed Instructions and Improves Bus Bandwidth
• Co-processor Interface to Companion 32-bit Peripherals: TS68881 and TS68882 Floating Point Co-processors
• Pipelined Architecture with High Degree of Internal Parallelism Allowing Multiple Instructions to be Executed Concurrently
• High Performance Asynchronous Bus in Non-multiplexed and Full 32 Bits
• Dynamic Bus Sizing Efficiently Supports 8-, 16-, 32-bit Memories and Peripherals
• Full Support of Virtual Memory and Virtual Machine
• Sixteen 32-bit General-purpose Data and Address Registers
• Two 32-bit Supervisor Stack Pointers and 5 Special Purpose Control Registers
• 18 Addressing Modes and 7 Data Types
• 4-Gbyte Direct Addressing Range
• Processor Speed: 16.67 MHz - 20 MHz - 25 MHz
• Power Supply: 5.0 VDC ± 10%
