AX99100

PCIe to Multi I/O Controller

1 Introduction

General Description

1.1

AX99100, PCI Express to Multi-I/O Controller, is a single chip solution for PCI express-based high performance

Serial, Parallel port, SPI and Local Bus connectivity. It provides rich features and highly configurability for variety

products.

AX99100 is a fully integrated, single-lane PCI express end-point controller and SerDes with rich high

performance peripherals such as four High Speed Serial Ports, one Parallel Port, I

2C Master, one High Speed SPI

and Local Bus interface. AX99100 also provides rich GPIO ports can be controlled by software driver for some

automation control applications.

The High Speed Serial Ports with the throughput up to 25Mbps, it can works with RS-232/RS-422/RS-485

multi-protocol transceivers and allow easy reconfigured Full/Half-duplex, Loopback and Termination resistors by

software. The Parallel Port is compatible with IEEE 1284 and supports SPP, Nibble, Byte and ECP modes. An I

interface is provided to configure AX99100 device options through an external EEPROM after chip reset and also

supports to access other I

2C device. SPI master provides a full-duplex, synchronous serial communication

interface (4 wires) to flexibly work with numerous SPI peripheral devices. Local Bus interface provides

configurable asynchronous or synchronous, 8 or 16 bits data bus width with specified endian type and address/data

multiplexed or separated bus type access mode to support variety slave interface access types. All the GPIO pins

are programmable and can be used as Input or Output. AX99100 supports 8 dedicated GPIO and every serial port

pins can be configured as GPIO by software.

Generally, the clock source of AX99100 is from PCIe slot. AX99100 don’t need any other clock source for the

main operations. But AX99100 still supports a clock input from external oscillator for those special baud rate

generated for UART, SPI and Local Bus used. AX99100 also integrates power-on reset circuit and 3.3V to 1.2V

voltage regulator on-chip to provide simplifies reset and power supply for the core power of the chip. It supports

single power operation and reduces the overall BOM cost.

AX99100 is available in 68-pin QFN RoHS compliant package and supports commercial grade operating

temperature range from 0 to 70°C and Industrial grade operating temperature range from -40 to 85°C.

AX99100 provides cost effective solution to enable simple, easy, and low cost integration capability for PCIe to

rich interface conversion applications. It could also provide highly programmable flexibility and compatibility for

many applications such as serial, parallel and Bridge for home automation and Industrial control.
