Microcontroller

The AT89S8253 is a low-power, high-performance CMOS 8-bit microcontroller with12K bytes of In-System Programmable (ISP) blaze program store advance and 2K bytes of EEPROM selective information memory. The twisting is manufactured using Atmels high-density non-volatile memory engineering perception and is compatible with the industry-standard MCS-51 instruction adjust and pinout. The on-chip downloadable flash everyows the program memory to be reprogrammed in- corpse finished an SPI series port or by a conventional nonvolatile memory programmer. By conceive a versatile 8-bit important processing unit with downloadable Flash on a monolithic chip, the Atmel AT89S8253 is a powerful microcontroller which provides a highly-flexible and cost-effective response to some embedded control applications. The AT89S8253 provides the spare-time activity standard features: 12K bytes of In-System Programmable Flash, 2K bytes of EEPROM, 256 bytes of RAM, 32 I/O lines, programmable watchdog timepiece, 2 data pointers, triad 16-bit timer/counters, a six-vector, four-level interrupt architecture, a unspoilt duplex attendant port, on-chip oscillator, and clock circuitry. In addition, the AT89S8253 is knowing with static logical organization for operation down to set frequency and supports two software system selectable power economic system tempers.

The Idle Mode kale the CPU while allowing the RAM, timer/counters, serial port, and interrupt system to pass on functioning. The Power-down mode saves the RAM contents exclusively freezes the oscillator, disabling all different chip functions until the next international interrupt or hardware reset. The on-board Flash/EEPROM is accessible through the SPI serial interface. retention understandapt active forces the SPI bus into a serial programme interface and allows the program memory to be written to or read from, unless one or more than lock bits open been activated. 1.1.3PIN rendering: 1.1.3.1 VCC Supply voltage (all packages suspend 42-PDIP). 1.1.3.2 GND Ground (all packages except 42-PDIP; for 42-PDIP GND connects only the logic core and the embedded...If you requirement to get a full essay, order it on our website: Ordercustompaper.com
