AT89LP51ED2-20PU  

Microcontrollers

The AT89LP51ED2-20PU is a low-power, high-performance CMOS 8-bit microcontroller unit (MCU) manufactured by Microchip Technology. It is based on the enhanced 8051 microarchitecture and is designed for a wide range of embedded control applications.

Description:

The AT89LP51ED2-20PU is a 28-pin package MCU with 8 kB of in-system programmable flash memory, 256 bytes of RAM, and 512 bytes of EEPROM. It operates with a single 2.7V to 6V power supply and features a wide operating temperature range of -40°C to +85°C. The device is available in a PDIP (Plastic Dual In-Line Package) package.

Features:

1. Enhanced 8051 CPU core with 128-byte on-chip RAM and 64-byte on-chip register file.
2. 8 kB in-system programmable flash memory with read-while-write capability.
3. 256 bytes of on-chip SRAM and 512 bytes of EEPROM for data storage.
4. 19 general-purpose I/O pins with 5V tolerant inputs.
5. Two 16-bit timer/counters with watchdog timer and two 8-bit timer/counters.
6. One full-duplex serial communication channel (UART).
7. One SPI serial port and one I2C serial port.
8. Low-power consumption with idle, power-down, and power-save modes.
9. Programmable clock frequency divider and internal RC oscillator.
10. On-chip debug features with background debug mode and debug interface.

Applications:

The AT89LP51ED2-20PU is suitable for a wide range of embedded applications, including but not limited to:

1. Industrial control systems
2. Home automation and smart home devices
3. Medical equipment and monitoring systems
4. Automotive control modules
5. Portable electronic devices
6. Consumer electronics
7. Telecommunication equipment
8. Battery-powered devices
9. Security systems
10. Sensor networks and IoT devices
