ATMEL 8-Bit 8051 Flash MCU, 64KB, 44-Pin LCC, SMD

The ATMEL 8-Bit 8051 Flash MCU is a high-performance CMOS microcontroller offering a robust solution for complex computing needs. It features a 64kB on-chip flash memory block for both code and data, alongside 2048 bytes of EEPROM for non-volatile data storage. The flash memory can be programmed in parallel or serial mode using the ISP capability or via software, with the programming voltage conveniently generated internally from the standard VCC pin.

Retaining all the features of the standard 80C52, this advanced microcontroller integrates a programmable counter array, 1792 bytes of expanded RAM (XRAM), and a hardware watchdog timer. It also includes an SPI interface, a keyboard interrupt interface, and a versatile enhanced UART (EUART) that facilitates multiprocessor communication. The improved X2 mode allows independent speed selection for the CPU and peripherals, optimising overall performance and power consumption.
