The T-11, also known as DC310, is a microprocessor that implements the PDP-11 instruction set architecture (ISA) developed by Digital Equipment Corporation. The T-11 was code-named "Tiny". It was developed for embedded systems and was the first single-chip microprocessor developed by DEC. It was sold openly and was used by DEC in disk controllers, auxiliary processors and in the Atari System 2 arcade game system. It operated at 2.5 MHz, used a 5 V power supply and dissipated less than 1.2 W. It contains 13,000 transistors, uses NMOS logic, and was fabricated in a NMOS process.
