Figure 4 illustrates the functional signal groups and Table 1 lists the signals and their
function.
The VCC and GND pins are separated into four groups to provide individual power sup-
ply connections for the address bus buffers, data bus buffers, and all other output
buffers and internal logic.

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%
