R65C22P4E

The R65C22P4E versatile interface adapter (VIA) is a very flexible I/O control device.In addition,this device contains a pair of very powerful 16-bit interval timers,a serial-to-parallel-to serial shift register and input data latching on the peripheral ports.

Features of the R65C22P4E are:(1)low power CMOS N-well silicon gate technology;(2)fully compatible with R65C22P4E devices;(3)two 8-bit bidirectional I/O ports;(4)two 16-bit programmable timer/counters;(5)serial bidirectional peripheral I/O;(6)1,2,3 and 4 MHz versions;(7)commercial and industrial temperature range versions;(8)wide variety of packages;(9)single +5Vdc power requirement;(10)TTL compatible peripheral control lines;(11)expanded "handshake" capability allows positive control of data transfers between processor and peripheral devices;(12)latched output and input registers on both I/O ports.

The absolute maximum ratings of the R65C22P4E can be summarized as:(1):the parameter is supply voltage,the symbol is VCC,the rating is -0.3 to +7.0,the unit is V;(2):the parameter is input voltage,the symbol is VIN,the rating is -0.3 to VCC+0.3,the unit is V;(3):the parameter is output voltage,the symbol is VOUT,the rating is -0.3 to VCC+0.3,the unit is V;(4):the parameter is operating temperature range commercial,the symbol is TA,the rating is 0 to +70,the unit is ;(5):the parameter is operating temperature range industrial,the symbol is TA,the rating is -40 to +85,the unit is ;(6):the parameter is storage temperature,the symbol is Tstg,the rating is -55 to +150,the unit is .
