TMP82C55A

      The TMP82C55A is designed as a CMOS high speed programmable input/output interface with three 8-bit I/O ports.24 I/O ports are divided into two groups (port A and port B) which are programmable independently by control words provided by MPU.The PPI has three operation modes and is copable of versalite interface between MPU and peripheral devices.It is fabricated using Toshibe's CMOS silicon gate technology.
      It has nine features.The first one is that it would have high speed version which means TRD-10ns max: TMP82C55AP-10/AM-10.The second one is that it would have loe power consumpution which means 2ms type. and 10uA max (@5V, stand-by).The third one is that it would have 5V +/- 10% single power supply.The fourth one is that it would have 24 programmable I/O ports.The next one is that it would have three operation modes (mode 0, mode 1, mode 2).The next one is that TMP82C55A would have bit set/reset capability.The next one is that it would have up to 8 output ports of port B and C are capable of driving a darlington teansistor (min. -1.0mA @ Voh=1.5V).The next one is about its extended operating temperature which would be from -40 to +85°C.The next one is that it would have available 40 pin standard DIP and SOP.That are all the features.
      Some TMP82C55A absolute maximum ratings have been concluded into several points as follow.The first one is about its supply voltage which would be from -0.5 to 7.0V.The second one is about its input voltage which would be from -0.5 to Vcc+0.5 V.The third one is about its power dissipation which would be 250mW.The next one is about its soldering temperature which would be 260°C.The next one is about its storage temperature which would be from -65 to +150°C.The next one is about its operating temperature which would be from -40 to +85°C.And so on.For more information please contact us.
