1. GENERAL DESCRIPTION
management controller is based on the micro-controller 80C32 and enhances the peripheral device in the
micro-controller, that including full function UART 16550A, System Management Bus (SMBus), system
hardware monitor, PWM Control, and GPIO. LPC interface is supported to communicate with system
management software (SMS). There are three physical protocols, which are SMIC (Server Management
Interface Chip), and KCS (Keyboard Controller Style), and BT (Block Transfer), between the management
controller W83910F and the system host.
W83910F is a management controller of Intelligent Platform Management Interface (IPMI). The
signals are including 8-bit Address/Data Bus, one address latch signal ALE, 8-bit high address bus, and
external data memory control signal that can record the System Event Log (SEL) data. Two programming
Chip Selects (CSA#, CSB#) are provided to select different memory ranges or I/O port ranges. The W83910F
provides two UART ports that are fully compatible with 16550A. One UART port supports full MODEM
connection signals which that can use external machine to communicate the management controller.
Another UART port only supports 3-wire connection signals which can communicate with the Intelligent
Chassis Management Bus (ICMB). There are 5-set System Management Buses (SMBus) in the W83910F,
which support 16 bytes Transfer/Receive FIFO and provide master/slave mode. One of SMBus is connected
to Intelligent Management Platform Bus (IPMB) to access/control chassis management controller or Field
Replaceable Unit (FRU) SEEPROM or AUX/Management-card connector. The others can be severed as
private I
2
C to access FRU SEEPROM on the memory or processor board.
Micro-controller 80C32 is built inside the W83910F. The maximum 64K-byte flash memory interface
analog voltage inputs , 3 fan tachometer inputs, 3 temperature sensors or remote temperature sensors.
The remote temperature sensing can be performed by thermistors, or 2N3904 NPN-type transistors, or
directly from Intel
TM
CPU with thermal diode output. The W83910F provides 3 PWM (pulse width
modulation) outputs to support fan speed control .
An 8-bit analog-to-digital converter (ADC) was built inside W83910F. The W83910F can monitor 7
There are three physical interfaces (SMIC, KCS, and BT) in the W83910F to request/response the IPMI
messages. GPIO pins are supported to control/detect the external signal. The grouped interrupt and interrupt
status are supported to give micro-controller as a service pointer when the GPIO input signal has a edge
transition.
The system management software (SMS) can communicate with W83910F through the LPC interface.
the package of 128-pin PQFP.
For the spacing saving consideration of the Baseboard Management Controller system, W83910F is in
