• Manufacturer: Megawin Technology

Features
Operating Voltage:
2
80C51 Central Processing Unit
8KB on-chip program memory
ISP capability; optional 1KB/2KB/4KB ISP memory shared with data flash memory.
IAP capability; up to 7K bytes programmable data flash available shared with ISP memory.
On-Chip 256 bytes scratch-pad RAM and 256 bytes auxiliary RAM; capable of addressing up to
64 K bytes external memory
MOVC-disabling, encrypting, and locking flash memory realize security mechanism.
Three 16-bit timer/counter, Timer2 is an up/down counter with programmable clock output on
P1.0
Eight sources, four-level-priority interrupt capability
Enhanced UART, provides frame-error detection and hardware address-recognition
Dual DPTR for fast-accessing of data memory
15 bits Watch-Dog-Timer with 8-bit pre-scalar, one-time enabled
Power control: Idle mode and Power-down mode; Power-down can be woken-up by
P3.2/P3.3/P4.2/P4.3
Low EMI: inhibit ALE emission
Four 8-bit bi-directional ports; extra four-bit additional P4 are available for PLCC-44 and
PQPF-44
