The GS-DL020 teaches students the advanced concepts of sequential digital logic design, which is the final element to understanding microprocessor and microcontroller logic. With the GS-DL020, all necessary logic components are included and pre-mounted for fast and easy implementation of sequential circuits and many of the standard sequential components that are used as building blocks in microprocessors. These sequential circuits include the SR latch, D latch, register, memory, finite state machine (FSM), and several real-life controller examples. A detailed lab manual is included with the trainer, which can be used directly in labs to supplement the theory taught in an introductory digital logic course. In addition, all of the combinational logic circuits implemented in our GS-DL010 combinational logic trainer can also be implemented using this trainer.

Some of the sequential logic circuits that can be implemented with this trainer include but are not limited to:

• SR latch
• D latch with and without enable
• D flip-flop with and without enable
• SR flip-flop
• JK flip-flop
• T flip-flop
• 4-bit register
• Serial-to-parallel shift register
• 4-bit up counter
• 4-bit up/down counter
• 2 °— 2 register file
• Finite state machine (FSM)
• Rotating lights controller
• Car security system controller
• Jeopardy® contestant response controller
• Traffic light controller
• other custom controller
