80C51 Microcontroller - 12T

Part No.	W78C052D
Datasheet	W78C52D_W78C052D.pdf
Description	The W78C052D microcontroller supplies a wider frequency and supply voltage range than most 8-bit microcontrollers on the market. It is compatible with the industry standard 80C51 microcontroller series.The W78C052D contains four 8-bit bidirectional parallel ports、one extra 4-bit bit-addressable I/O port (Port 4) and two additional external interrupts (INT2 ,INT3)、two 16-bit timer/counters、one watchdog timer and a serial port. These peripherals are supported by a seven-source、two-level interrupt capability. There are 128 bytes of RAM and an 8K byte mask ROM for application programs.
Features	Fully static design Supply voltage of 4.5V to 5.5V DC-40 MHz operation 256 bytes of on-chip scratchpad RAM 8K bytes of on-chip mask ROM 64K bytes program memory address space 64K bytes data memory address space Four 8-bit bidirectional ports Two 16-bit timer/counters One full duplex serial port Seven-source、two-level interrupt capability One extra 4-bit bit-addressable I/O port Two additional external interrupts INT2 ,INT3 Watchdog timer EMI reduction mode Built-in power management Code protection
