EZ-USB Series 2100 Family The Anchor Chips EZ-USB™ family (AN21XX/AN23XX) provides significant improvements over other USB architectures including an enhanced 8051 core, 4 or 8 Kbytes of RAM, an intelligent USB core, and high-performance I/O ports. The family includes 16 different products to accommodate the needs of different systems.
EZ-USB Series 2100 High-Speed Peripheral Shared Memory Flash ROM EEPROM EPROM ROM Micro- processor DMS Controller (Optional) USB Protocol Controller Chip USB Port I/O The EZ-USB RAM architecture provides design and software flexibility .
EZ-USB Series 2100 Single-Chip Solution Lower overall system cost Minimum board space with 44 PQFP and 80 PQFP packages Quicker design and faster time to market than other USB solutions Minimal design.
EZ-USB Series 2100 The focus of the EZ-USB family is to provide the peripheral designer a multitude of design configurations and migration paths. The “soft,” programmable nature of the EZ-USB architecture provides flexibility while minimizing risks.
EZ-USB Series 2100 Enumeration and ReNumeration Anchor Chips’ proprietary ReNumeration™ function is the means by which the enhanced 8051 firmware is downloaded. How It W orks Upon power-up or plug-in, the EZ-USB chip automatically enumerates as a default USB device.
EZ-USB Series 2100 USB firmware develop- ment is faster since there is less code to write. This reduction in firmware allows the design team to concentrate more on software development for the peripheral function. Fewer 8051 MIPs are dedicated to USB processing.
EZ-USB Series 2100 This diagram shows how conventional USB contr ollers handle a thr ee-stage USB setup transaction called “Get Descriptor .” The serial data flowing over the USB is shown as thr ee stages: Setup, Data and Status. The number ed ar r ows indicate transfers between the USB, endpoint FIFOs, and micropr ocessor memory .
EZ-USB Series 2100 T urbo Performance T o make full use of the USB bandwidth, the EZ-USB family has large endpoint buffers and a fast method for transferring data into and out of the buffers. W ith the EZ-USB architecture, bulk and isochronous endpoints can be configured as double-buffered with maximum packet sizes.
EZ-USB Series 2100 T o write data to outside logic, the 8051 loads a data pointer with a USB FIFO register addr ess, and then executes a “movx a,@dptr” instruction to move a byte from the FIFO to the 8051 accumulator .
EZ-USB Series 2100 Flexible for Many Applications Loading 8051 Firmware from the Host Options for Loading 8051 Firmware The EZ-USB family provides the peripheral developer with four options for loading its 8051 firmware.
EZ-USB Series 2100 More Endpoint Buffer Memory The EZ-USB chip supports more endpoints and provides more endpoint buffer memory than any other USB-device solution in the market.
EZ-USB Series 2100 EZ-USB Series 2100 Xcelerator Development Kit Development Board The EZ-USB Xcelerator develop- ment board is compact and powerful. It provides an AN2131QC, 64 kilobytes of external RAM, two UARTS, and user-programmable seven segment display , LED indicators, and switches.
EZ-USB Series 2100 Anchor Utilities Anchor Chips provides the best tools to accelerate the developer ’s firmware development. The USB Control Panel allows the developer to send and receive interrupt, bulk, and isochronous packets and standard USB device requests without first developing the host- based driver for the specific application.
