8-bit Embedded EEPROM for User Data Storage AB MCUs
- This page contains information on a product that is not recommended for new designs.
The HC08AB Family is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs) with embedded EEPROM or Flash memory for user data storage. All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.
Product Details
