46 / 52 page  Philips Semiconductors Preliminary specification XA-S3 XA 16-bit microcontroller 32 K/1 K OTP/ROM/ROMless, 8-channel 8-bit A/D, low voltage (2.7 V–5.5 V), I2C, 2 UARTs, 16 MB address range 2000 Dec 01 46 VDD–0.5 0.45V 0.7VDD 0.2VDD–0.1 tCHCL tC tCLCH tCLCX tCHCX SU00842 Figure 32. External Clock Drive VDD–0.5 0.45V 0.2VDD+0.9 0.2VDD–0.1 NOTE: AC inputs during testing are driven at VDD –0.5 for a logic ‘1’ and 0.45V for a logic ‘0’. Timing measurements are made at the 50% point of transitions. SU00703A Figure 33. AC Testing Input/Output VLOAD VLOAD+0.1V VLOAD–0.1V VOH–0.1V VOL+0.1V NOTE: TIMING REFERENCE POINTS For timing purposes, a port is no longer floating when a 100mV change from load voltage occurs, and begins to float when a 100mV change from the loaded VOH/VOL level occurs. IOH/IOL ≥ ±20mA. SU00011 Figure 34. Float Waveform VDD EA RST XTAL1 XTAL2 VSS VDD (NC) CLOCK SIGNAL SU00591B Figure 35. IDD Test Condition, Active Mode All other pins are disconnected VDD EA RST XTAL1 XTAL2 VSS VDD (NC) CLOCK SIGNAL SU00590B VDD Figure 36. IDD Test Condition, Idle Mode All other pins are disconnected |
