UPD8257C-2 Description

Short technical summary and product information.

The NEC D8257C-2 is a programmable Direct Memory Access (DMA) controller integrated circuit designed for efficient data transfer. It operates with a single 5.0V power supply, with a nominal voltage of 5V and a tolerance of +/-10%, allowing for operation between 4.5V and 5.5V. The device has a maximum power dissipation of 1W and an I/O capacitance of 20pF.

 

This IC is designed for through-hole mounting and comes in a Dip package. It operates within a temperature range of 0°C to 70°C. The part number is D8257C-2, manufactured by NEC Electronics.

 

Additional features mentioned include priority DMA request logic, channel inhibit logic, terminal count and modulo 128 outputs, automatic load mode, and a single TTL clock. The maximum power supply voltage is rated at 7.0V, with a minimum of -0.5V.

 

This component is listed as obsolete. It is suitable for applications requiring direct memory access control where a 5V supply is utilized.
