Overview
The COP8CBE9HVA9 is an 8-bit microcontroller from National Semiconductor's COP8 8C series. It features a COP8 core processor operating at a speed of 6.67MHz. The device includes 8KB (8K x 8) of FLASH memory and 256 bytes of RAM. Connectivity options include Microwire/Plus (SPI) and UART/USART interfaces. It also integrates a 16x10-bit A/D converter. The component is housed in a 44-PLCC package measuring 16.59x16.59 mm.
Feature Summary
- Integrates a dedicated 16x10-bit analog-to-digital converter for signal processing tasks.
- Supports serial communication via Microwire/Plus and UART/USART protocols.
- Utilizes an 8-bit COP8 core architecture for embedded control applications.
Applications
- Embedded systems requiring analog input monitoring
- Industrial control units with serial communication needs
- Consumer electronics utilizing 8-bit processing
Procurement Notes
Verify the manufacturer status as National Semiconductor has been acquired by Texas Instruments. Confirm that the specific suffix 'V' indicates the correct temperature range and package variant required for your design. Ensure compatibility with existing firmware architectures designed for the COP8 family before procurement.
Selection Notes
Select this component when an 8-bit solution with integrated ADC and serial interfaces is required. The 8KB FLASH allows for moderate code storage, while the 256-byte RAM suits simple control logic. Consider the PLCC package size for PCB layout constraints and verify voltage supply requirements against system specifications.
Part Context
This part belongs to the COP8 8C series, a line of 8-bit microcontrollers known for integrating peripherals like ADCs and timers on-chip. The COP8 architecture was widely used in cost-sensitive embedded applications before transitioning to more modern 8051-compatible or ARM-based solutions within the same product lineage.
Replacement Considerations
Check for direct pin-compatible upgrades within the extended COP8 family. Note that National Semiconductor's microcontroller division is now part of Texas Instruments; consult TI documentation for equivalent modern replacements if the legacy COP8 architecture is no longer suitable for new designs.
