W83910F preliminary publication release date: feb,2001 - 1 - revision 0. 46 1. general descript ion W83910F is a management controller of intelligent platform management interface (ipmi). the 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. micro - controller 80c32 is built inside the W83910F. the maximum 64k - byte flash memory interface 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 pro vided 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 co ntroller. 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 p rovide 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. an 8 - bit analog - to - digital converter (adc) was built inside W83910F. the W83910F can monitor 7 analog voltage inputs , 3 fan tachometer inputs, 3 temperature sensors or remote temperature sens ors. 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 . the system management software (sms) can communicate with W83910F through the lpc interface. 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 s ignal. 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. for the spacing saving consideration of the baseboard management controller system, W83910F i s in the package of 128 - pin pqfp.
