Notes: 1. All testing to be performed using worst-case test conditions unless otherwise specified.
2. Maximum operating junction temperature (TJ) = +125°. Minimum case operating temperature (TC) = -55°. This device is not
tested at TC = +125°. Testing is performed by setting the junction temperature TJ = +125°and allowing the case and ambient
temperatures to rise and fall as necessary so as not to exceed the maximum junction temperature.
3. Capacitance is periodically sampled rather than 100% tested.
4. Power dissipation may vary in between limits depending on the application.

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
