I/O Controller 0.09A 160-Pin PQFP

The FDC37C93xAPM incorporates a keyboard interface, real-time clock, SMSC"s true CMOS 765B floppy disk controller, advanced digital data separator, 16 byte data FIFO, two 16C550 compatible UARTs, one Multi-Mode parallel port which includes ChiProtect circuitry plus EPP and ECP support, IDE interface, on-chip 24 mA AT bus drivers, game port chip select and two floppy direct drive support, as well as ACCESS.bus, soft power management and SMI support. The true CMOS 765B core provides 100% compatibility with IBM PC/XT and PC/AT architectures in addition to providing data overflow and underflow protection. The SMSC advanced digital data separator incorporates SMSC"s patented data separator technology, allowing for ease of testing and use. Both onchip UARTs are compatible with the NS16C550. The parallel port, the IDE interface, and the game port select logic are compatible with IBM PC/AT architecture, as well as EPP and ECP. The FDC37C93xAPM incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power down modes. The FDC37C93xAPM provides features for compliance with the “Advanced Configuration and Power Interface Specification” (ACPI). These features include support of both legacy and ACPI power management models through the selection of SMI or SCI. It implements a 24- bit power management timer, power button override event (4 second button hold to turn off the system) and either edge triggered interrupts. The FDC37C93xAPM provides support for the ISA Plug-and-Play Standard (Version 1.0a) and provides for the recommended functionality to support Windows "95. Through internal configuration registers, each of the FDC37C93xAPM"s logical device"s I/O address, DMA channel and IRQ channel may be programmed. There are 480 I/O address location options, 13 IRQ options, and three DMA channel options for each logical device. The FDC37C93xAPM does not require any external filter components and is, therefore, easy to use and offers lower system cost and reduced board area. The FDC37C93xAPM is software and register compatible with SMSC"s proprietary 82077AA core. 5 Volt Operation ISA Plug-and-Play Standard (Version 1.0a) Compatible Register Set Soft Power Management, SMI Support ACPI/Legacy Support SCI/SMI Support Power Management Timer Power Button Override Event Either Edge Triggered Interrupts ACCESS.bus Support 8042 Keyboard Controller 2K Program ROM 256 Bytes Data RAM Asynchronous Access to Two Data Registers and One Status Register Supports Interrupt and Polling Access 8 Bit Timer/Counter Port 92 Support Fast Gate A20 and Hardware Keyboard Reset Real Time Clock MC146818 and DS1287 Compatible 256 Bytes of Battery Backed CMOS in Two Banks of 128 Bytes 128 Bytes of CMOS RAM Lockable in 4x32 Byte Blocks 12 and 24 Hour Time Format Binary and BCD Format 1 mA Standby Current (typ) Intelligent Auto Power Management 2.88MB Super I/O Floppy Disk Controller Licensed CMOS 765B Floppy Disk Controller Core Enhanced Digital Data Separator Serial Ports IDE Interface 16 Bit Address Qualification 160 Pin QFP Package
