Mobile KBC with SFI, ADC and DAC with SMSC SentinelAlert!TM
General Description
The KBC1100L is an integrated Keyboard/System Management Controller which incorporates a highperformance 8051 Micro-Controller, an LPC Bus/Firmware Hub Host Interface and a Super I/O. The KBC1100L is powered by two separate supply planes (VCC1, VCC0) to provide "instant on" and sophisticated system power management functions. The KBC1100L power control circuitry supports multiple low power-down modes. The KBC1100L 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 KBC1100L 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. The KBC1100L incorporates a Standby Power Reset Generator (RESGEN) which monitors the VCC1 power input and generates the internal VCC1 power on reset for the KBC1100L. The KBC1100L also outputs VCC1RST# which can be used to reset the Flash memory on the Shared Flash Interface (SFI). A block diagram of the KBC1100L including the distribution of the supply planes is shown in Figure 1 on page 5.
