CDP1802CD

The Harris Corporation's CDP1802CD is a microprocessor-based integrated circuit (IC) that was widely used in the 1970s and 1980s. It is also known as the COSMAC (Compact Object-Oriented Solid-state Automatic Computer) microprocessor.

Description:

The CDP1802CD is a 16-bit microprocessor that was designed for use in embedded systems and consumer electronics. It is a member of the CDP1802 family of microprocessors, which were developed by Harris Semiconductor. The CDP1802CD is a CMOS (Complementary Metal-Oxide-Semiconductor) version of the CDP1802, which offers improved power efficiency and performance compared to earlier models.

Features:

Some of the key features of the CDP1802CD include:

1. 16-bit data bus and 8-bit address bus, allowing for up to 64KB of memory.
2. A rich instruction set that supports a wide range of operations, including arithmetic, logical, and data transfer operations.
3. A flexible memory addressing scheme that supports direct, indirect, indexed, and extended memory addressing modes.
4. An on-chip clock oscillator and a clock divider, allowing for flexible clocking options.
5. An on-chip power supply regulator, which simplifies the power supply requirements for the microprocessor.
6. A built-in 4-channel programmable interval timer (PIT), which can be used for time-based operations and control.
7. A built-in 8-channel input/output (I/O) port, which can be used for interfacing with external devices.

Applications:

The CDP1802CD was used in a wide range of applications, including:

1. Embedded systems for industrial control and automation.
2. Consumer electronics, such as video game consoles and home computers.
3. Medical equipment, such as patient monitoring systems and diagnostic devices.
