Overview
The COP8TAC9HLQ8 is an 8-bit CMOS Flash microcontroller from the COP8TAx9 family, featuring 4k bytes of program memory and 128 bytes of RAM. It operates within a voltage range of 2.25V to 2.75V and supports temperatures from -40°C to +85°C. The device utilizes a 44-pin LLP package and includes a 16-bit timer, MICROWIRE/PLUS interface, and ACCESS.Bus compatibility.
Feature Summary
- Features 4k bytes of in-system reprogrammable Flash memory with security features and high endurance.
- Includes a 16-bit timer supporting PWM, external event counting, and input capture modes.
- Supports MICROWIRE/PLUS and ACCESS.Bus synchronous serial interfaces for communication.
- Incorporates EMI reduction technology with low radiated emissions and power save modes.
Applications
- Low electromagnetic interference embedded control systems
- Applications requiring in-system programming via serial interfaces
- Battery-powered devices utilizing low voltage operation
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to confirm pin count and package type. Ensure code does not call Boot ROM functions if targeting masked ROM production equivalents. Confirm temperature range and voltage specifications match application requirements before procurement.
Selection Notes
Select this component for designs requiring moderate memory capacity with in-system programmability. Consider the 44-pin LLP package for space-constrained layouts. Evaluate the need for ACCESS.Bus or MICROWIRE/PLUS interfaces when choosing between similar COP8 variants.
Part Context
This part belongs to the COP8TAx9 series, which provides identical features to the COP8TAB9 except for doubled program memory. The series is designed for applications needing full-featured controllers with low EMI characteristics and development flexibility using standard software tools.
Replacement Considerations
COP8TAB9HLQ8 offers equivalent functionality with 2k bytes of Flash memory instead of 4k bytes. Verify that the reduced memory size meets application code requirements before substitution.
