The AT80C51RD2-RLTUM is a high-performance 8-bit microcontroller from Microchip Technology (formerly Atmel) based on the industry-standard 80C51 core. It operates at clock speeds up to 40MHz and supports a supply voltage range of 2.7V to 5.5V, making it suitable for a wide variety of embedded applications. This ROMless variant requires external program memory, providing flexibility for custom firmware execution.
The device includes 256 bytes of internal scratch pad RAM and an additional 1024 bytes of on-chip XRAM, totaling 1280 bytes of RAM. It features 32 I/O lines, a full-duplex enhanced UART with dedicated baud rate generator, three 16-bit timer/counters, a 5-channel programmable counter array (PCA), and a hardware watchdog timer. Integrated peripherals include power-on reset, PWM, and multiple power control modes (Idle and Power-down).
The AT80C51RD2-RLTUM is housed in a 44-pin VQFP package with a gull wing termination, suitable for surface mount assembly. It is specified for the industrial temperature range of -40°C to +85°C. The microcontroller is designed for embedded control applications requiring moderate computational power, serial communication, and flexible I/O.
The operating voltage range is 2.7V to 5.5V.
The device operates from -40°C to +85°C (industrial grade).
It is packaged in a 44-VQFP (10x10 mm) surface mount package.
The part is marked as RoHS3 Compliant.
The maximum clock speed is 40 MHz.
The device has 32 I/O lines.
No, it is a ROMless variant requiring external program memory.
