PC87309

- March 1998 Highlights PRELIMINARY April 1998 PC87309 SuperI/O Plug and Play Compatible Chip in Compact 100-Pin VLJ Packaging Highlights General Description The PC87309 is a single-chip solution to the most commonly used ISA, EISA and MicroChannel® peripherals in a compact, 100-pin VLJ packaging. This fully Plug and Play (PnP) and PC97 compatible chip conforms to the Plug and Play ISA Specification Version 1.0a, May 5, 1994, and meets specifications defined in the PC97 Hardware Design Guide. The PC87309 incorporates: a Floppy Disk Controller (FDC), a Mouse and Keyboard Controller (KBC), two enhanced UARTs, one of which is with Infrared (IR) support, a full IEEE 1284 parallel port and support for Power Management (PM). The chip also provides a separate configuration register set for each module. The Infrared (IR) interface complies with the HP-SIR and SHARP-IR standards, and supports all four basic protocols for Consumer Remote Control circuitry (RC-5, RC-6, NEC, RCA and RECS 80). For flexible UART and IR support, the PC87309 offers two operation modes: q Mode 1: Full-IR Mode UART1 works as UART; UART2 works as fully IRcompliant device Mode 2: Two-UART Mode Either both UARTs work as UARTs, or UART1 works as UART and UART2 works as partially IR-compliant device, providing only IRRX and IRTX support q Outstanding Features q Full SuperI/O functionality in compact, cost-effective 100-pin VLJ packaging PC97 compliant q PC87309 Block Diagram DMA IRQ Channels Floppy Drive I...
