ICH - 82801AA. The first version of the ICH was released in June 1999 along with the Intel 810 northbridge.While its predecessor, the PIIX, was connected to the northbridge through an internal PCI bus with a bandwidth of 133 MB/s, the ICH used a proprietary interface (called by Intel Hub Interface) that linked it to the northbridge through an 8-bit wide, 266 MB/s bus.
Option ROMs are necessary to enable non-Plug and Play peripheral devices to boot and to extend the BIOS to provide support for any non-Plug and Play peripheral device in the same way that standard and motherboard-integrated peripherals are supported. Option ROMs are also used to extend the BIOS or to add other firmware services to the BIOS.
The device comes in a variety of generations featuring the usual peripherals: Internal oscillator, Timer including pulse-width modulation (PWM), Watchdog timer, USART, Serial Peripheral Interface (SPI) bus, Inter-Integrated Circuit , Analog-to-digital converter (ADC) options: 10/12/14-bit successive-approximation ADC; 16/24-bit delta sigma ADC
[1] [2] The term "plug and play" has since been expanded to a wide variety of applications to which the same lack of user setup applies. [ 3 ] [ 4 ] Expansion devices are controlled and exchange data with the host system through defined memory or I/O space port addresses, direct memory access channels, interrupt request lines and other ...
Award BIOS setup utility on a standard PC. A modern BIOS setup utility has a text user interface (TUI) or graphical user interface (GUI) accessed by pressing a certain key on the keyboard when the PC starts. Usually, the key is advertised for short time during the early startup, for example "Press DEL to enter Setup".
It is widely used for attaching lower-speed peripheral integrated circuits (ICs) to processors and microcontrollers in short-distance, intra-board communication. Several competitors, such as Siemens , NEC , Texas Instruments , STMicroelectronics , Motorola , [ 1 ] Nordic Semiconductor and Intersil , have introduced compatible I 2 C products to ...
8255 Programmable Peripheral Interface (PPI) DRAM/SRAM controller; XT Keyboard controller; IBM PC compatibility is provided by C&T's 82C206 Integrated Peripheral Controller (IPC), introduced by C&T in 1986. This chip, like its predecessor the 82C100, provides equivalent functionality to the TTL chips on the PC/AT's mainboard, namely: [1]
