COP310L Datasheet | National Semiconductor

Description The COP410L and COP411L Single-Chip N-Channel Microcontrollers are members of the COPSTM family fabricated using N-channel silicon gate MOS technology These Controller Oriented Processors are plete microputers containing all system timing internal logic ROM RAM and I O necessary to implement dedicated control functions in a variety of applications Features include single supply operation a variety of output configuration options with an instruction set internal architecture and I O scheme designed to facilitate keyboard input display output and BCD data manipulation The COP411L is identical to the COP410L but with 16 I O lines instead of 19 They are an appropriate choice for use in numerous human interface control environments Standard test procedures and reliable high-density fabrication techniques provide the medium to large volume customers with a customized Controller Oriented Processor at a low end-product cost The COP310L and COP311L are exact functional equivalents but extended temperature versions of COP410L and COP411L respectively The COP401L should be used for exact emulation Features Y Y Y Y Y Y Y Y Y Low cost Powerful instruction set 512 x 8 ROM 32 x 4 RAM 19 I O lines (COP410L) Two-level subroutine stack 16 ms instruction time Single supply operation (4 5V - 6 3V) Low current drain (6 m A max) Internal binary counter register with MICROWIRETM serial I O capability General purpose and TRI-STATE outputs LSTTL CMOS patible in and out Direct drive of LED digit and segment lines Software hardware patible with other members of COP400 family Extended temperature range device COP310L COP311L (b40 C to a 85 C) Block Diagram TL DD 6919 - 1 FIGURE 1 COP410L COPSTM and MICROWIRETM are trademarks of National Semiconductor Corporation TRI-STATE is a registered trademark of National Semiconductor Corporation C1995 National Semiconductor Corporation TL DD 6919 RRD-B30M105 Printed in U S A COP410L COP411L Absolute Maximum Ratings If...
