Overview
The AT89C51RC2DWD-SLSUM is an 8-bit microcontroller based on the 80C51 architecture, manufactured by Atmel (Microchip). It features 32 Kbytes of in-system programmable Flash memory and 512 bytes of internal RAM. The device supports a maximum clock frequency of 40 MHz and operates within a voltage range of 3.0 V to 5.5 V. It includes a full-duplex UART, three 16-bit timers/counters, and a 10-bit ADC with eight multiplexed inputs. The component is housed in a 44-pin Green VQFP package.
Feature Summary
- Integrates 32 Kbytes of Flash memory for non-volatile program storage with in-system programming capability.
- Includes a 10-bit Analog-to-Digital Converter (ADC) supporting eight multiplexed input channels.
- Features a Programmable Counter Array (PCA) providing five channels for PWM, capture, and compare functions.
- Supports In-System Programming via CAN, UART, or IAP interfaces using on-chip boot programs.
Applications
- Industrial control systems requiring robust communication protocols like CAN.
- Embedded applications utilizing analog signal processing through integrated ADC.
- Motor control designs leveraging PCA-based PWM generation.
- Data acquisition systems needing multiple analog input channels.
Procurement Notes
Verify the specific suffix 'SLSUM' against official Microchip documentation to confirm the package type and temperature grade. Ensure compatibility with existing PCB footprints for the 44-pin VQFP form factor. Confirm that the supply voltage requirements align with the target system's power rails before procurement.
Selection Notes
Select this component when a standard 80C51 core requires enhanced peripheral integration, specifically CAN bus connectivity and high-resolution ADC capabilities. It serves as a suitable upgrade over basic 80C51 variants for applications demanding flexible I/O management and reliable data retention without external memory components.
Part Context
This part belongs to the AT89C51RC series, which extends the classic MCS-51 instruction set with advanced peripherals. The series is designed for cost-effective embedded solutions, combining high-density Flash memory with versatile interface options. It maintains pin and instruction compatibility with industry-standard 80C51 devices while adding significant functional depth.
Replacement Considerations
Direct replacements include other members of the AT89C51RC family, such as the AT89C51RC2, provided pinout and peripheral configurations match the design requirements. Verify that any substitute maintains the same Flash capacity and package dimensions.
