80C51 Microcontroller - 12T

Part No.	W78L812A
Datasheet	W78LE812_W78L812A.pdf
Description	The W78L812 is an 8-bit microcontroller which can accommodate a wide range of supply voltages with low power consumption. The instruction set for the W78L812 is fully compatible with the standard 8051. The W78LE812 contains an 8K bytes Flash EPROM; a 256 bytes RAM; four 8-bit bi-directional and bit-addressable I/O ports; an additional 5-bit I/O port P4; three 16-bit timer/counters; a hardware watchdog timer and a serial port. These peripherals are supported by a fourteen sources two-level interrupt capability.
