Varies with operation frequency. Measurement Conditions: • VCC=3.0 to 3.6V • Input high and low voltage: VIH=1.5V, VIL=0.5V • Output high and low voltage: VOH=1.5V, VOL=1.5V Memory Expansion Mode and Microprocessor Mode (with no wait state) NOTES: 1. Values guaranteed only when the microcomputer is used independently. A maximum of 35ns is guaranteed for td(BCLK-AD)+tsu(DB-BCLK). 2. Varies with operation frequency: tac2(RD-DB)=(tcyc/2-35)ns.max tac2(AD-DB)=(tcyc-35)ns.max 18ns.max tw(WR)(1) 18ns.max |
