EZ-USB AT2LP implements a bridge function between a USB port and one or two ATA- or ATAPI-based mass storage device ports.
EZ-USB FX2LP is low-power, highly integrated USB 2.0 microcontroller.
EZ-USB NX2LP-Flex is a fixed-function, low-power programmable USB to NAND controller.
Feature
EZ-USB FX2™
• Single-chip integrated USB 2.0 Transceiver, SIE, and Enhanced 8051 Microprocessor
• Software: 8051 code runs from:
— Internal RAM, which is downloaded via USB
— Internal RAM, which is loaded from EEPROM
— External memory device (128 pin package
• Four programmable BULK/INTERRUPT/ISOCHRONOUS endpoints
— Buffering options: double, triple and quad
• 8- or 16-bit external data interface
• GPIF
— Allows direct connection to most parallel interface
— Programmable waveform descriptors and configuration registers to define waveforms
— Supports multiple Ready (RDY) inputs and Control (CTL) outputs
• Integrated, industry standard enhanced 8051:
— Up to 48-MHz clock rate
— Four clocks per instruction cycle
— Two USARTS
— Three counter/timers
— Expanded interrupt system
— Two data pointers
• Supports bus-powered applications by using renumeration
• 3.3V operation
• Smart Serial Interface Engine
• Vectored USB interrupts
• Separate data buffers for the SETUP and DATA portions of a CONTROL transfer
• Integrated I2C-compatible controller, runs at 100 or 400 kHz
• 48-MHz, 24-MHz, or 12-MHz 8051 operation
• Four integrated FIFOs
— Brings glue and FIFOs inside for lower system cost
— Automatic conversion to and from 16-bit buses
— Master or slave operation
— FIFOs can use externally supplied clock or asyn chronous strobes
— Easy interface to ASIC and DSP ICs
• Special autovectors for FIFO and GPIF interrupts
• Up to 40 general-purpose I/Os
• Four package options—128-pin TQFP, 100-pin TQFP, 56-pin QFN and 56-pin SSOP
• Four packages are defined for the family: 56 SSOP, 56 QFN, 100 TQFP, and 128 TQFP
