Product Summary
The HD6340P is a CMOS direct memory access controller. It is upwardly compatible with the NMOS DMAC HD68450. The HD6340P performs one of several blocks of data transfer between memory and peripheral device at high speed. The number of operands in a block is determined by a transfer count.
Parametrics
HD6340P absolute maximum ratings: (1)Supply Voltage: -0.3V to 7.0V; (2)Input voltage: -0.3V to VCC+0.3V; (3)Operating temperature range: 0℃ to 70℃; (4)Storage temperature: -55℃ to 150℃.
Features
HD6340P features: (1)HD68000 Bus compatible; (2)4 independent DMA channels with programmable priority; (3)Memory-to-memory, memory-to-device, device-to-memory transfers; (4)Programmable 8-bit or 16-bit I/O Device Types; (5)Auto-Request and External-request Transfer Modes; (6)Interface Lines for Requesting, Acknowledge, and incidental control of the peripheral devices; (7)CMOS +5 Volts operation; (8)Fast transfer rates: up to 6.25 Mbytes/sec. at 12.5MHz.
