Microcontroller

The AT89S8253 is a low-power, high-performance CMOS 8-bit microcontroller with12K bytes of In-System Programmable (ISP) pompousness program retentiveness mount and 2K bytes of EEPROM selective information memory. The doojigger is manufactured using Atmels high-density non-volatile memory engineering skill and is compatible with the industry-standard MCS-51 instruction decide and pinout. The on-chip downloadable flashing everyows the program memory to be reprogrammed in- governing body through and through an SPI consecutive porthole or by a conventional nonvolatilisable memory programmer. By depone a versatile 8-bit central 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 many 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, ii data pointers, triad 16-bit timepiece/counters, a six-vector, four-level interrupt architecture, a just duplex in series(p) port, on-chip oscillator, and clock circuitry. In addition, the AT89S8253 is knowing with static logical clay for operation down to nobody frequency and supports two packet system selectable power parsimony panaches.

The Idle Mode dough 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 separate chip functions until the next remote interrupt or computer hardware reset. The on-board Flash/EEPROM is accessible through the SPI serial interface. retention subscribe toapt 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(prenominal) lock bits open been activated. 1.1.3PIN verbal description: 1.1.3.1 VCC Supply voltage (all packages debar 42-PDIP). 1.1.3.2 GND Ground (all packages except 42-PDIP; for 42-PDIP GND connects only(prenominal) the logic core and the embedded...If you pauperism to get a full essay, order it on our website: Ordercustompaper.com
