Atmel 8051 AT89S52 AVR 40 Pin DIP Microcontroller

The Atmel 8051 AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard 89C51 instruction set and pinout.

Features:

• It is a high-performance CMOS microcontroller with Flash Technology
• The unit operates at a wide range of 4 – 5.5 volts, so it is a low-power IC
• The device supports In-system Programming both page and byte mode for the Flash memory
• The operational frequency of CPU is up to 33MHz but can be altered for saving energy
• The module has a quick programming time with 10,000 read/write cycles
• The Random Access memory is organized in 256×8 bits
• The serial communication takes place through a full duplex UART module
• It comes with a reset option, three 16-bit timers and eight interrupts
• AT89S52 has two power modes, i.e., idle mode in which stops the processing unit while other peripherals keep working and power-down mode that halts oscillator and other functions and saves RAM contents

Specifications:

• Compatible with MCS-51® Products
• Original 8K Bytes of In-System Programmable (ISP) Flash Memory
• Endurance: 1000 Write/Erase Cycles
• 4.0V to 5.5V Operating Range
• Fully Static Operation: 0 Hz to 33 MHz
• Three-level Program Memory Lock
• 256 x 8-bit Internal RAM
• 32 Programmable I/O Lines
• Three 16-bit Timer/Counters
• Eight Interrupt Sources
• Full Duplex UART Serial Channel
• Low-power Idle and Power-down Modes
• Interrupt Recovery from Power-down Mode
• Watchdog Timer
• Dual Data Pointer
• Power-off Flag
