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.
The enhanced 8051 core provides five times the performance of the
standard 8051, while maintaining complete 8051 software compatibil-
ity. With on-chip RAM, firmware code can be downloaded from the
host PC. This allows the peripheral manufacturer to easily modify and
transfer new code to current and new users. This on-chip memory
eliminates the need for external memory.
The EZ-USB family supports high-bandwidth transfers by providing
an efficient mechanism to move data between external memory and
the USB FIFOs. Using this “turbo mode,” the 8051 core can transfer
1024 bytes of data in or out of an isochronous FIFO in 338 microsec-
onds. This leaves a high percentage of the bandwidth for the processor
to service the application. The EZ-USB family also supports an equiva-
lent data transfer rate for bulk packets of over 2 Mbytes per second,
which is more than the USB bandwidth.
The EZ-USB family conforms to the high-speed (12 Mbps) require-
ments of USB Specification version 1.0, including support for remote
wake-up. The internal SRAM replaces Flash memory, EEPROM,
EPROM, or masked ROM that is conventionally used in other USB
solutions.
The EZ-USB family offers two packages, a 44 PQFP and an 80 PQFP.
All EZ-USB devices are pin- and software-compatible. And, all RAM
versions have ROM equivalents to allow easy migration for high-
volume applications.
