General Description\nThe KBC1122 is an integrated Keyboard/System Management Controller which incorporates a high\nperformance 8051 Micro-Controller, an LPC Bus Interface which provides a Firmware Hub Interface\nand integrated Super I/O/LPC Resources. The KBC1122 is powered by two separate supply planes\n(VCC1, VCC0) to provide “instanton” and sophisticated system power management functions. The\nKBC1122 power control circuitry supports multiple low power-down modes.\nThe KBC1122 incorporates a Direct Battery Management (DBM) with SMSC SentinelAlert! accessible by the 8051. Together with external remote temperature sensor(s) can provide complete Analog Monitoring & Control System. The KBC1122 DBM includes an 8 channel ADC, a 3 channel DAC with SMSC SentinelAlert! and up to 2 SMSC SentinelAlert! GPIO's, two channel one-pin Temperature Sensor Communication Links, and a hardware protect output that requires no programming or 8051 intervention to operate.\nThe KBC1122 incorporates a Standby Power Reset Generator (RESGEN) which monitors the VCC1\npower input and generates the internal VCC1 power on reset for the KBC1122. The KBC1122 also\noutputs VCC1RST# which can be used to reset the Flash memory on the Shared Flash Interface (SFI).PRODUCT FEATURES\n3.3V Operation with 5V Tolerant Buffers\nACPI 1.0b/2.0 and PC99a/PC2001 Compliant\nLPC Interface with Clock Run Support\n— Serial IRQ Interface Compatible with Serialized IRQ Support for PCI Systems\n— 15 Direct IRQs\n— Three 8-Bit DMA Channels\n— ACPI SCI Interface\n—nSMI\n— Shadowed write only registers\nLPC/Firmware Hub Host Flash Interface\n— Single Byte FWH Memory Read and FWH Memory Write Support\n— FWH ID Support\n— 16MB FWH Flash and Register Addressing, 128K Legacy BIOS Addressing\n— Single Byte LPC Memory Read and LPC Memory Write Support\nSerial Peripheral Interface (SPI)\n— 3-pin Full Duplex serial communication interface.\n— Dual Ported Controller with Keeper Circuit 8 MByte Shared FlashROM Interface (SFI)\n— 8051/Host CPU HardwareArbitrated Interface\n— 0.5 - 8MB - Host System BIOS & 8051 Keyboard\n— 8051 64KB Code Space Accessible as Separate 32KB Pages in Flash\n— Low-Power Flash Access Modes\n— 8051-Programmable Flash Access Protection\n– Read/Write/No-Access Protection\n– Variable Bank Sizes\nHost Flash Address Redirection for Recovery\nSerial Flash Programming Interface\nTwo Power Planes\n— Low Standby Current in Sleep Mode\n— Intelligent Auto Power Management for Super I/O\n— Main powered blocks power supplied by standby\npower plane and controlled by power\nmanagement signals\n3-Port ACPI Embedded Controller Interface\nConfiguration Register Set\n— Compatible with ISA Plug-and-Play Standard(Version 1.0a)\n— Four Pin Selectable Addressing Options\n— 8051-Programmable Base Address
