8-bit MCU Series (80C51-based)

Part No.	W78L054C
Datasheet	W78LE52C_W78L052C.pdf
Description	The W78L054C is an 8-bit microcontroller which can accommodate a wide supply voltage range with low power consumption. The instruction set for the W78L051C is fully compatible with the standard 8051. The W78L054C contains an 16K bytes Flash EPROM; a 128 bytes RAM; four 8-bit bi-directional and bit-addressable I/O ports; an additional 4-bit I/O port P4; two 16-bit timer/counters; a hardware watchdog timer and a serial port. These peripherals are supported by seven sources two-level interrupt capability.
Features	Fully static design 8-bit CMOS microcontroller Wide supply voltage of 2.4V to 5.5V 256 bytes of on-chip scratchpad RAM 16 KB electrically erasable/programmable Flash EPROM 64 KB program memory address space 64 KB data memory address space Four 8-bit bi-directional ports One extra 4-bit bit-addressable I/O port, additional INT2 / INT3 (available on 44-pin PLCC/QFP package) Two 16-bit timer/counters One full duplex serial port (UART) Watchdog Timer seven sources, two-level interrupt capability EMI reduction mode Built-in power management Code protection mechanism
