AT89C52 3D Model
The AT89C52 is an 8-bit microcontroller and belongs to Atmel's 8051 families.
The AT89C52 is a low-power, high-performance CMOS 8-bit microcomputer with 8K bytes of Flash programmable and erasable read-only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 and 80C52 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C52 is a powerful microcomputer that provides a highly-flexible and cost-effective solution to many embedded control applications.
• Compatible with MCS-51™ Products
• 8K Bytes of In-System Reprogrammable Flash Memory
• Endurance: 1,000 Write/Erase Cycles
• Fully Static Operation: 0 Hz to 24 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
• Programmable Serial Channel
• Low-power Idle and Power-down Modes
The Atmel microcontroller can be programmed using a variety of software available on the market. The most popular platforms are Arduino and Keil uVision, to mention a few. Keil is recommended if you want to do serious programming and expand with community help.
To program the Atmel microcontroller, we'll need an IDE (Integrated Development Environment), which acts as a programming environment. A compiler converts our software into HEX files, which can be read by MCUs. Our hex file is dumped into our MCUs using an IPE (Integrated Programming Environment).
Keil uVision IDE is an integrated development environment.

USBASP is a programmer.
A programmer is required to dump or upload our code into an Atmel IC; the most often used programmer is the USBASP, which must be purchased separately. Simulating your program in software before attempting it on hardware will also save you time. As a result, you can simulate your applications using software such as Labcenter's ISIS proteus.

Every code byte in the Flash array can be written, and the entire array can be erased, by using the appropriate combination of control signals. The write operation cycle is self-timed and once initiated, will automatically time itself to completion. All major programming vendors offer worldwide support for the Atmel microcontroller series. Please contact your local programming vendor for the appropriate software revision.
