AT80C52X2DNW-3CSUM

The AT80C52X2DNW-3CSUM is a microcontroller unit (MCU) manufactured by Atmel, which is now a part of Microchip Technology. This MCU is based on the 8052 microcontroller architecture and is designed for a wide range of embedded applications.

Description:

The AT80C52X2DNW-3CSUM is a high-performance, low-power, 8-bit CMOS microcontroller that features enhanced functionality and flexibility compared to its predecessors. It is housed in a 40-pin dual-in-line package (DIP) and operates over a wide temperature range of -40°C to +85°C.

Features:

1. CPU: 8052-compatible CPU with enhanced instruction set.
2. Memory: 8 KB of on-chip Flash memory for program storage, 256 bytes of on-chip RAM for data storage, and an additional 8 KB of external memory support.
3. I/O: 32 I/O lines, which can be configured as general-purpose I/O or as specialized functions such as timers, counters, and communication interfaces.
4. Timers: Two 16-bit timer/counters with three modes of operation (8-bit auto-reload, 13-bit timer, and 16-bit timer).
5. Serial Communication: One USART (Universal Synchronous/Asynchronous Receiver/Transmitter) for serial communication, supporting SPI, LIN, and I2C protocols.
6. Interrupts: Five software-priority levels and 14 interrupt sources for efficient handling of external and internal events.
7. Power Management: Low-power modes, including idle and power-down modes, to conserve energy in battery-powered applications.
8. Watchdog Timer: An independent watchdog timer for system reliability and reset functionality.
9. Input/Output: Capable of driving up to 16 mA per I/O pin, supporting both sink and source configurations.
10. Security: In-system programmable (ISP) and in-application programmable (IAP) features for secure firmware updates and protection.
