Winbond Electronics Corporation W83910F

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. The W83910F provides two UART ports that are fully compatible with 16550A.

GENERAL DESCRIPTION

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 provided to select different memory ranges or I/O port ranges. 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.
