COP8CDR9KMT8

Overview

The COP8CDR9KMT8 is an 8-bit microcontroller based on the COP8 core, manufactured by National Semiconductor. It features 32KB of FLASH program memory and 1KB of RAM. The device includes a 16-channel, 10-bit Analog-to-Digital Converter (ADC). It supports communication via Microwire/Plus (SPI) and UART/USART interfaces. The maximum clock frequency is specified as up to 20 MHz in some sources, while other documentation indicates a line speed of 2 MHz. It operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates a 16-channel, 10-bit Analog-to-Digital Converter for precision voltage supervision and signal acquisition.
• Provides robust connectivity options including Microwire/Plus (SPI) and UART/USART serial interfaces.
• Features 32KB of non-volatile FLASH program memory for code storage.

Applications

• Precision voltage supervisor systems requiring reset output functionality.
• Embedded control applications utilizing analog signal processing via the integrated ADC.
• Serial communication devices requiring SPI or USART interface support.

Procurement Notes

Verify the specific package type and pin count against your design requirements, as datasheets may list variations such as TSSOP or LLP packages. Confirm the exact maximum clock frequency specification with the manufacturer, as conflicting values exist between different documentation sources. Ensure compatibility with the COP8 architecture before integration into existing systems.

Selection Notes

Select this component when an 8-bit COP8 core is required alongside significant analog input capabilities. The presence of a 16-channel 10-bit ADC makes it suitable for applications needing multiple sensor inputs without external converters. Consider the available memory size and serial interface options relative to system complexity.
