AM79C940AKC

The AM79C940AKC is one member of the AM79C940 family which designed as one kind of media access controller for Ethernet.It is specifically designed to address applications where multiple I/O peripherals are present, and a centralized or system specific DMA is required.Also it provides a complete Ethernet node solution with an integrated 10BASE-T transceiver, and supports up to 25-MHz system clocks.

Features of the AM79C940AKC are:(1)integrated controller with 10BASE-T transceiver and AUI port;(2)supports IEEE 802.3/ANSI 8802-3 and Ethernet standards;(3)84-pin PLCC and 100-pin PQFP packages;(4)arbitrary byte alignment and little/big endian memory interface supported;(5)internal/external loopback capabilities;(6)integrated manchester encoder/decoder;(7)1 MHz-25 MHz system clock speed;(8)sleep mode allows reduced power consumption for critical battery powered applications;(9)direct FIFO read/write access for simple interface to DMA controllers or l/O processors.

The absolute maximum ratings of the AM79C940AKC can be summarized as:(1)storage temperature:-65°C to +150°C;(2)ambient temperature under bias:0°C to +70°C;(3)supply voltage to AVSS or DVss (AVDD, DVDD):-0.3 V to +6.0 V.If you want to know more information such as the electrical character-istics about the AM79C940AKC,please download the datasheet in www.seekic.com or www.chinaicmart.com .
