1 Features 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 ModesDescriptionThe AT89C52 is a low-power, high-performance CMOS 8-bit microcomputer with 8 Kbytes of flash Programmable and erasable read only memory (PEROM). The deviceis manufactured using Atmel s high-density nonvolatile memory technology and iscompatible with the industry-standard 80C51 and 80C52 instruction set and on-chip flash allows the program memory to be reprogrammed in-system or by aconventional nonvolatile memory programmer. By combining a versatile 8-bit CPUwith flash on a monolithic chip, the Atmel AT89C52 is a powerful microcomputerwhich provides a highly-flexible and cost-effective solution to many embedded Microcontroller with 8K Bytes FlashAT 8 9 C 5 2 Not Recommended for New Designs.
