In semi-sleep (T1 wakes every half second, >I'm prestuffing the timer) I measure 89uA. Oh, dear, looks like I'll have to look elsewhere to get that 10 year life from a 1AH battery, then! This figure seems a little high - I recently did a product with an Epson LCD chip, with 4:1 mux (presumably more power hungry), which took about 40uA at 5V. ____ ____ _/ L_/ Mike Harrison / White Wing Logic / wwl@netcomuk.co.uk _/ L_/ _/ W_/ Hardware & Software design / PCB Design / Consultancy _/ W_/ /_W_/ Industrial / Computer Peripherals / Hazardous Area /_W_/
