Overview
The COP8CCR9LVA8 is an 8-bit CMOS Flash microcontroller from the COP8 family, featuring 32 kbytes of Flash program memory and 1 kbyte of volatile RAM. It integrates a 10-bit Analog-to-Digital Converter with up to 16 channels, two USARTs, and three timers. The device supports dual clock operation with a clock doubler for speeds up to 20 MHz. It includes Virtual EEPROM functionality using Flash memory and features a Brownout Reset circuit operating between 4.17V and 4.5V. The component is available in 44-pin WQFN, 44/68-pin PLCC, and 48/56-pin TSSOP packages.
Feature Summary
- Virtual EEPROM capability allows emulation of non-volatile storage by copying data blocks between RAM and Flash memory.
- Dual clock system enables switching between high-speed (up to 10 MHz) and low-speed (32.768 kHz) oscillators for power management.
- Integrated EMI reduction technology utilizes gradual turn-on output drivers and internal smoothing filters to minimize radiated emissions.
- True in-system emulation support allows software debugging on final production boards via standard connectors.
Applications
- Embedded control systems requiring large program memory and low electromagnetic interference.
- Applications needing analog signal processing with integrated multi-channel ADC.
- Systems utilizing serial communication protocols supported by dual USART peripherals.
- Battery-powered devices benefiting from multiple low-power sleep modes and dual-clock architecture.
Procurement Notes
Verify the specific suffix 'LVA8' against the official Texas Instruments datasheet SNOS535I to confirm package type and temperature range compatibility. Ensure that the required voltage levels align with the COP8CCR9 series specifications, specifically the 4.17V to 4.5V Brownout reset threshold. Confirm availability status as this product line may be subject to discontinuation notices.
Selection Notes
Select this component when a modified Harvard architecture is required for efficient data table access from program memory. Consider the COP8CCR9 variant if a Brownout Reset feature is necessary for voltage monitoring within the 4.17V to 4.5V range. Evaluate the pin count requirements against the available 44, 48, 56, and 68-pin package options to ensure sufficient I/O allocation.
Part Context
This microcontroller belongs to the COP8CBR9/COP8CCR9/COP8CDR9 family, which shares core architectural features including 32k Flash memory and advanced peripherals. The COP8CCR9 variant is distinguished by its specific Brownout Reset voltage range compared to the COP8CBR9 and the absence of BOR in the COP8CDR9. All variants support in-system programming and emulation capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers are not provided in the source documentation. Verify cross-compatibility with other COP8 family members based on pinout and peripheral configuration.
