AT89LV52

Features Compatible with MCS-51™ Products 8K Bytes of Reprogrammable Flash Memory – Endurance: 1,000 Write/Erase Cycles 2.7V to 6V Operating Range Fully Static Operation: 0 Hz to 12 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 Description The AT89LV52 is a low-voltage, high-performance CMOS 8-bit microcomputer with 8K bytes of Flash programmable and erasable read only memory. 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 onchip 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 AT89LV52 is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications. The AT89LV52 operates at 2.7 volts up to 6.0 volts.
