W78E052DDG

The W78E052DDG is an 8-bit microcontroller unit featuring an 8051-based CMOS core that is fully compatible with 8052 instruction sets. It provides 8 kilobytes of Flash program memory and 256 bytes of RAM. This microcontroller supports dual operating modes: 12T mode, which allows for speeds up to 40 MHz at 5V, and 6T Mode for operation up to 20 MHz at 5V.

It is equipped with 32 general-purpose I/O pins, three 16-bit timer/counters, a hardware watchdog timer, and a serial port (UART/USART). The device operates over a wide voltage range of 2.4V to 5.5V, making it suitable for various logic level operations. The W78E052DDG is available in a 40-DIP package and is designed for through-hole mounting.

Key features include its 8-bit architecture, 8KB Flash memory, 256 bytes RAM, and a maximum clock frequency of 40 MHz. It supports external oscillator types and offers peripherals like Power-On Reset (POR) and Watchdog Timer (WDT). The operating temperature range is from -40°C to 85°C (TA).

This microcontroller is well-suited for embedded applications requiring a robust and versatile 8-bit solution. Its compatibility with the widely used 8052 architecture simplifies integration into existing designs.
