Features
z 80C51 Central Processing Unit
z 63KB on-chip program memory
z ISP capability; optional 1KB/2KB/4KB ISP memory shared with application flash memory.
z On-Chip 256 bytes scratch-pad RAM and 1024 bytes auxiliary RAM; Be capable of
addressing up to 64 K bytes external memory
z MOVC-disabling, encrypting, and locking flash memory realize security mechanism.
z Three 16-bits timer/counter, Timer2 is an up/down counter with programmable clock output
on P1.0
z Eight sources, four-level-priority interrupt capability
z Enhanced UART, provides frame-error detection and hardware address-recognition
z Dual DPTR for fast-accessing of data memory
z 15 bits Watch-Dog-Timer with 8-bit pre-scalar, one-time enabled
z Power control: Idle mode and Power-Down mode; Power-Down can be woken-up by
P3.2/P3.3/P4.2/P4.3
