DS80C400-FNY简介:Network Microcontroller
GENERAL DESCRIPTION
The DS80C400 network microcontroller offers the highest
integration available in an 8051 device. Peripherals include
a 10/100 Ethernet MAC, three serial ports, a CAN 2.0B
controller, 1-Wire® Master, and 64 I/O pins.
To enable access to the network, a full applicationaccessible
TCP IPv4/6 network stack and OS are provided
in the ROM. The network stack supports up to 32
simultaneous TCP connections and can transfer up to
5Mbps through the Ethernet MAC. Its maximum systemclock
frequency of 75MHz results in a minimum instruction
cycle time of 54ns. Access to large program or data
memory areas is simplified with a 24-bit addressing
scheme that supports up to 16MB of contiguous memory.
To accelerate data transfers between the microcontroller
and memory, the DS80C400 provides four data pointers,
each of which can be configured to automatically increment
or decrement upon execution of certain data pointer-related
instructions. The DS80C400’s hardware math accelerator
further increases the speed of 32-bit and 16-bit multiply
and divide operations as well as high-speed shift,
normalization, and accumulate functions.
The High-Speed Microcontroller User’s Guide and the High-Speed
Microcontroller User’s Guide: Network Microcontroller Supplement
should be used in conjunction with this data sheet.
