PRECAUTIONS ON USE * Be sure to ground the pins of AVDD, DVDD, VRT, VRB, VR1, VR2, and VR3 via high-frequency capacitor. Place the high-frequency capacitor as close as possible to the pin. * To avoid generation of undesired current owing to indetermination of internal logic, set CE to "H" at powering on and input more than five clock pulses just after operation (CE: "H" "L"). 3 MB40C328 BLOCK DIAGRAM CKSEL DSEL VINA CLKOA AVDD DVDD VREFT AVDD Mode setting VRT Timing circuit CLKA CLK CLK select VR3 VR2 VR1 B ch CLKB A output buffer DA0 to DA7 B output buffer DB0 to DB7 Output selector FF A ch FF Timing circuit VRB AVDD AVSS RESET 4 CE CLKOB AVSS DVSS OE VREFB MB40C328 ABSOLUTE MAXIMUM RATINGS Parameter Power supply voltage Input/output voltage Storage temperature Symbol Rating Unit Min.
