The Power-down mode saves the RAM contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset.Atmel AT89C52 PROGRAMMER Datasheets Context Search Catalog Datasheetġ996 - flash programmer circuit for AT89c2051Ībstract: isp programmer circuit for AT89c2051 In-system Programmer for AT89c51 low cost eeprom programmer circuit diagram atmel AT89C52 PROGRAMMER flash programmer circuit for AT89c55 atmel at89c52 architecture flash programmer circuit for AT89c51 led interface with AT89C51 spi flash programmer schematic The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt system to continue functioning. In addition, the AT89S52 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The AT89S52 provides the following standard features: 8K bytes of Flash, 256 bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator, and clock circuitry. By combining a versatile 8-bit CPU with in-system programmable Flash on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller 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 instruction set and pinout. The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory.
