Mechanical Data” on page 43.) and into MIL-STD-1835.
Electrical Characteristics
Absolute Maximum Ratings
Stresses above the absolute maximum rating may cause permanent damage to the
device. Extended operation at the maximum levels may degrade performance and affect
reliability.

1. This device is not tested at TC = +125°C. Testing is performed by setting the junction temperature Tj = +125°C and allowing
the case and ambient temperatures to rise and fall as necessary so as not to exceed the maximum junction temperature.

Description
The TS68040 is Atmel’s third generation of 68000-compatible, high-performance, 32-bit microprocessors. The TS68040 is a virtual memory microprocessor employing multiple, concurrent execution units and a highly integrated architecture to provide very high performance in a monolithic HCMOS device.

Features
• 26-42 MIPS Integer Performance
• 3.5-5.6 MFLOPS Floating-Point-Performance
• IEEE 754-Compatible FPU
• Independent Instruction and Data MMUs
• 4K bytes Physical Instruction Cache and 4K bytes Physical Data Cache Accessed Simultaneously
• 32-bit, Nonmultiplexed External Address and Data Buses with Synchronous Interface
• User-Object-Code Compatibility with All Earlier TS68000 Microprocessors
• Multimaster/Multiprocessor Support via Bus Snooping
• Concurrent Integer Unit, FPU, MMU, Bus Controller, and Bus Snooper Maximize Throughput
• 4G bytes Direct Addressing Range
• Software Support Including Optimizing C Compiler and UNIX® System V Port
• IEEE P 1149-1 Test Mode (JTAG)
• f = 25 MHz, 33 MHz; VCC = 5V ± 5%; PD = 7W
• The Use of the TS88915T Clock Driver is Suggested
