A82370-16

The A82370-16 is designed as one kind of MegaCore function implements a programmable DMA controller which controls memory-to-peripheral and memory-tomemory data transfers and provides block memory initialization capability.

Features of the A82370-16 are:(1)optimized for FLEX® architecture;(2)provides four independent channels;(3)offers static read/write or handshaking modes;(4)includes direct bit set/reset capability;(5)uses approximately 1,201 FLEX logic elements (LEs);(6)functionally based on the Intel 8237A and Harris 82C37A devices.

It has four DMA channels, each of the four DMA channels has a base word count register, which is a 16-bit register containing the beginning word count for DMA transfers.If auto-initialization is enabled, the A82370-16 loads the base word count value into the current word count register at the conclusion of a DMA cycle.If you want to know more information such as the electrical characteristics about it, please download the datasheet in www.seekic.com or www.chinaicmart.com .
