- In-system programming by on-chip UART boot program and IAP capability
- Integrated power monitor (POR - PFD) to supervise internal power supply
- 14-sources 4-level Interrupts
- Three 16-bit timers/counters
- Full duplex UART compatible 80C51
- Five ports - 32 + 4 digital I/O lines
- Five-channel 16-bit PCA
- Double data pointer
- 21-bit Watchdog timer (7 Programmable bits)
- 10-bit resolution Analog-to-digital converter (ADC) with 8 multiplexed Inputs
- On-chip Emulation logic (Enhanced hook system)
- Power saving modes - Idle mode, Power-down mode
