143 / 185 page  ST72321 143/185 SUPPLY CURRENT CHARACTERISTICS (Cont’d) 12.4.3 RUN and SLOW Modes (ROM devices) 12.4.4 WAIT and SLOW WAIT Modes (ROM devices) Notes: 1. Data based on characterization results, tested in production at VDD max. and fCPU max. 2. Measurements are done in the following conditions: - Progam executed from RAM, CPU running with RAM access. There is no increase in consumption if programs are ex- ecuted in ROM - All I/O pins in input mode with a static value at VDD or VSS (no load) - All peripherals in reset state. - CSS and LVD disabled. - Clock input (OSC1) driven by external square wave. - In SLOW and SLOW WAIT mode, fCPU is based on fOSC divided by 32. To obtain the total current consumption of the device, add the clock source (Section 12.5.3 and Section 12.5.4) and the peripheral power consumption (Section 12.4.7). Symbol Parameter Conditions Typ Max 1) Unit IDD Supply current in RUN mode 2) fOSC=2MHz, fCPU=1MHz fOSC=4MHz, fCPU=2MHz fOSC=8MHz, fCPU=4MHz fOSC=16MHz, fCPU=8MHz 1.3 2.0 3.6 7.1 3.0 5.0 8.0 15.0 mA Supply current in SLOW mode 2) fOSC=2MHz, fCPU=62.5kHz fOSC=4MHz, fCPU=125kHz fOSC=8MHz, fCPU=250kHz fOSC=16MHz, fCPU=500kHz 0.6 0.7 0.8 1.1 2.7 3.0 3.6 4.0 Symbol Parameter Conditions Typ Max 1) Unit IDD Supply current in WAIT mode 2) fOSC=2MHz, fCPU=1MHz fOSC=4MHz, fCPU=2MHz fOSC=8MHz, fCPU=4MHz fOSC=16MHz, fCPU=8MHz 1.0 1.5 2.5 4.5 3.0 4.0 5.0 7.0 mA Supply current in SLOW WAIT mode 2) fOSC=2MHz, fCPU=62.5kHz fOSC=4MHz, fCPU=125kHz fOSC=8MHz, fCPU=250kHz fOSC=16MHz, fCPU=500kHz 0.07 0.1 0.2 0.35 1.2 1.3 1.8 2.0 |
