The AT80C32X2-RLTUM is an 8-bit microcontroller from Atmel, built around the 80C51 core. It is ROMless, requiring external program memory for operation. This device is well-suited for cost-sensitive embedded applications where the 8051 instruction set and external memory are needed.
Key specifications include a clock speed of 40/20MHz, 256 bytes of RAM, 32 general-purpose I/O pins, and integrated peripherals such as a Power-On Reset (POR) and an internal oscillator. Connectivity is provided via UART/USART for serial communication.
The microcontroller is available in a 44-LQFP package with a 44-VQFP (10x10mm) supplier device package, supporting surface mount assembly. It operates over an industrial temperature range of -40°C to 85°C and requires a supply voltage of 4.5V to 5.5V. Compliance statuses include RoHS3 Compliant, MSL 1 Unlimited, and REACH Unaffected (unverified).
Typical applications include embedded control systems, data acquisition, and industrial automation where external ROM, EPROM, or Flash memory is used to store program code.
