80C51 Microcontroller - 12T

Part No.	W78L516A
Datasheet	W78LE516_W78L516A.pdf
Description	The W78L516 is an 8-bit microcontroller which has an in-system programmable Flash EPROM for firmware updating. The instruction set of the W78L516 is fully compatible with the standard 8052. The W78L516 contains a 64K bytes of main ROM and a 4K bytes of auxiliary Flash EPROM which allows the contents of the 64KB main EPROM to be updated by the loader program located at the 4KB auxiliary EPROM; 512 bytes of on-chip RAM; four 8-bit bi-directional and bit-addressable I/O ports; an additional 4-bit port P4; three 16-bit timer/counters; a serial port. These peripherals are supported by a eight sources two-level interrupt capability.
Features	Fully static design 8-bit CMOS microcontroller Wide supply voltage of 2.4V to 5.5V 64K bytes of in-system programmable Flash EPROM for Application Program (AP Flash EPROM) 4K bytes of auxiliary ROM for Loader Program (LDROM) 512 bytes of on-chip RAM. (including 256 bytes of AUX-RAM, software selectable) 64K bytes program memory address space and 64K bytes data memory address space Four 8-bit bi-directional ports One 4-bit multipurpose programmable port Three 16-bit timer/counters One full duplex serial port Eight-sources, two-level interrupt capability Built-in power management Code protection
