At89c52 programmer2/28/2023 ![]() By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C52 is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. 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. Circuit description The circuit of temperature indicator is designed around microcontroller AT89C52 where DS1621 is used as temperature sensor. The following on-chip peripherals are simulated by the Keil Software Vision Debugger. ![]() ![]() The AT89C52 is a low-power, high-performance CMOS 8-bit microcomputer with 8K bytes of Flash programmable and erasable read only memory (PEROM). As we know that programming language C is less complicated with well-defined syntax in compare to Assembly language so we write program for microcontroller in C. The Atmel AT89C52 is an 8051-based Fullly Static 24MHz CMOS controller with 32 I/O Lines, 3 Timers/Counters, 8 Interrupts/2 Priority Levels, UART, Three-Level Program Memory Lock, 8K Bytes Flash Memory, 128 Bytes On-chip RAM. ![]()
