The MC6840CP is a programmable timer module manufactured by Motorola, Inc. Motorola was a major American multinational company known for its pioneering work in electronics and telecommunications. Founded in 1928, Motorola initially focused on the production of radios and later expanded into semiconductors, telecommunications equipment, and consumer electronics. The company played a significant role in the development of technologies such as mobile communications and microprocessors.
Over the years, Motorola underwent various restructures and changes, eventually splitting into two independent companies in 2011: Motorola Solutions and Motorola Mobility. Motorola Solutions focuses on communications products and services for enterprise and government customers, whereas Motorola Mobility, which was acquired by Google in 2012 and later by Lenovo in 2014, specializes in mobile devices.
The semiconductor division of Motorola, which produced the MC6840CP, became part of Freescale Semiconductor in 2004. Freescale was later acquired by NXP Semiconductors in 2015. Therefore, the heritage of the MC6840CP can be traced through Motorola to Freescale and subsequently to NXP Semiconductors, a global leader in the semiconductor industry.

The MC6840CP is a programmable timer module commonly used in embedded systems and microcontroller applications. It is suitable for applications requiring precise timing and control, such as industrial automation, motor control, and digital signal processing. The chip can generate accurate time delays, create pulse-width modulation (PWM) signals, and manage event counting. It is often employed in systems that require multitasking, where it helps coordinate tasks by generating interrupts at predefined intervals. Additionally, the MC6840CP is used in communication systems for baud rate generation and in various consumer electronics for timing-related functions. Its flexibility and programmability make it a versatile component for a wide range of timing applications.

The MC6840CP is typically found in a 40-pin dual in-line package (DIP). This type of package is designed for through-hole mounting on printed circuit boards and is common for integrated circuits from that era.
