Features:
- Core
- • Enhanced 8051 Core with single clock per machine cycle (1T)
- • Fully compatible instruction set with traditional 8051
- • 14 interrupt sources and 4 interrupt priority levels
- • Online debugging is supported
- Operating voltage
- • 2.0 to 5.5V
- • Built-in LDO
- Operating temperature
- • -40°C~85°C
- Flash memory
- • Up to 11Kbytes of Flash memory to be used to store user code
- • Configurable EEPROM size, 512bytes single page erased, can be repeatedly erased more than
100 thousand times.
