18 / 135 page  8.5.2 TMS320F2802x Current Consumption at 50-MHz SYSCLKOUT MODE TEST CONDITIONS VREG ENABLED VREG DISABLED IDDIO (1) IDDA (2) IDD IDDIO (1) IDDA (2) TYP(3) MAX TYP(3) MAX TYP(3) MAX TYP(3) MAX TYP(3) MAX Operational (Flash) The following peripheral clocks are enabled: • ePWM1/2/3/4 • eCAP1 • SCI-A • SPI-A • ADC • I2C • COMP1/2 • CPU Timer0/1/2 All PWM pins are toggled at 40 kHz. All I/O pins are left unconnected.(4) Code is running out of flash with 1 wait- state. XCLKOUT is turned off. 80 mA 90 mA 13 mA 18 mA 71 mA 80 mA 15 mA 18 mA 13 mA 18 mA IDLE Flash is powered down. XCLKOUT is turned off. All peripheral clocks are off. 16 mA 19 mA 64 μA 69 μA 17 mA 20 mA 120 μA 400 μA 64 μA 69 μA STANDBY Flash is powered down. Peripheral clocks are off. 4 mA 7 mA 10 μA 15 μA 4 mA 7 mA 120 μA 400 μA 10 μA 15 μA HALT Flash is powered down. Peripheral clocks are off. Input clock is disabled.(5) 50 μA 10 μA 15 μA 15 μA 25 μA 10 μA 15 μA (1) IDDIO current is dependent on the electrical loading on the I/O pins. (2) To realize the IDDA currents shown for IDLE, STANDBY, and HALT, clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register. (3) The TYP numbers are applicable over room temperature and nominal voltage. (4) The following is done in a loop: • Data is continuously transmitted out of SPI-A and SCI-A ports. • The hardware multiplier is exercised. • Watchdog is reset. • ADC is performing continuous conversion. • COMP1/2 are continuously switching voltages. • GPIO17 is toggled. (5) If a quartz crystal or ceramic resonator is used as the clock source, the HALT mode shuts down the on-chip crystal oscillator. 8.5.3 TMS320F2802x Current Consumption at 60-MHz SYSCLKOUT MODE TEST CONDITIONS VREG ENABLED VREG DISABLED IDDIO (1) IDDA (2) IDD IDDIO (1) IDDA (2) TYP(3) MAX TYP(3) MAX TYP(3) MAX TYP(3) MAX TYP(3) MAX Operational (Flash) The following peripheral clocks are enabled: • ePWM1/2/3/4 • eCAP1 • SCI-A • SPI-A • ADC • I2C • COMP1/2 • CPU-TIMER0/1/2 All PWM pins are toggled at 60 kHz. All I/O pins are left unconnected.(4) Code is running out of flash with 2 wait states. XCLKOUT is turned off. 90 mA 100 mA 13 mA 18 mA 80 mA 90 mA 15 mA 18 mA 13 mA 18 mA TMS320F28027, TMS320F28027-Q1, TMS320F28027F, TMS320F28027F-Q1, TMS320F28026 TMS320F28026-Q1, TMS320F28026F, TMS320F28026F-Q1, TMS320F28023 TMS320F28023-Q1, TMS320F28022, TMS320F28021, TMS320F28020, TMS320F280200 SPRS523P – NOVEMBER 2008 – REVISED FEBRUARY 2021 www.ti.com 18 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: TMS320F28027 TMS320F28027-Q1 TMS320F28027F TMS320F28027F-Q1 TMS320F28026 TMS320F28026-Q1 TMS320F28026F TMS320F28026F-Q1 TMS320F28023 TMS320F28023- Q1 TMS320F28022 TMS320F28021 TMS320F28020 TMS320F280200 |
