The device is manufactured using ATMEL Co.’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set and pin-out. 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 Co.’s AT89C51 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.Features:·Compatible with instruction set of MCS-51 products·4K bytes of in-system reprogrammable Flash memory·Endurance: 1000 write/erase cycles·Fully static operation: 0 Hz to 24 MHz·Three-level program memory lock·128×8-bit internal RAM·32 programmable I/O lines·Two 16-bit Timer/Counters·Six interrupt source·Programmable serial channel·Low-power idle and Power-down modesFunction Characteristic Description:The AT89C51 provides the following standard features: 4K bytes of Flash memory, 128 bytes of RAM, 32 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator and clock circuitry. In addition, the AT89C51 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, tim...
