90 / 134 page  www.ti.com 6.4 Current Consumption TMS320F2809, TMS320F2808, TMS320F2806 TMS320F2802, TMS320F2801, UCD9501 TMS320C2802, TMS320C2801 Digital Signal Processors SPRS230G – OCTOBER 2003 – REVISED FEBRUARY 2006 Table 6-1. TMS320F2808 Current Consumption by Power-Supply Pins at 100-MHz SYSCLKOUT IDD IDDIO(1) IDD3VFL IDDA18(2) IDDA33(3) MODE TEST CONDITIONS TYP(4) MAX TYP(4) MAX TYP MAX TYP(4) MAX TYP(4) MAX The following peripheral clocks are enabled: • ePWM1/2/3/4/5/6 • eCAP1/2/3/4 • eQEP1/2 • eCAN-A • SCI-A/B • SPI-A • ADC • I2C Operational 195 mA 230 mA 15 mA 27 mA 35 mA 40 mA 30 mA 38 mA 1.5 mA 2 mA All PWM pins are toggled (Flash) at 100 kHz. All I/O pins are left unconnected. Data is continuously transmitted out of the SCI-A, SCI-B, and eCAN-A ports. The hardware multiplier is exercised. Code is running out of flash with 3 wait states. XCLKOUT is turned off. Flash is powered down. XCLKOUT is turned off. The following peripheral clocks are enabled: IDLE 75 mA 90 mA 500 µA 2 mA 2 µA 10 µA 5 µA 50 µA 15 µA 30 µA • eCAN-A • SCI-A • SPI-A • I2C Flash is powered down. STANDBY 6 mA 12 mA 100 µA 500 µA 2 µA 10 µA 5 µA 50 µA 15 µA 30 µA Peripheral clocks are off. Flash is powered down. HALT Peripheral clocks are off. 70 µA 60 µA 120 µA 2 µA 10 µA 5 µA 50 µA 15 µA 30 µA Input clock is disabled. (1) IDDIO current is dependent on the electrical loading on the I/O pins. (2) IDDA18 includes current into VDD1A18 and VDD2A18 pins. In order to realize the IDDA18 currents shown for IDLE, STANDBY, and HALT, clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register. (3) IDDA33 includes current into VDDA2 and VDDAIO pins. (4) The TYP numbers are applicable over room temperature and nominal voltage. CAUTION The peripheral - I/O multiplexing implemented in the 280x devices prevents all available peripherals from being used at the same time. This is because more than one peripheral function may share an I/O pin. It is, however, possible to turn on the clocks to all the peripherals at the same time, although such a configuration is not useful. If this is done, the current drawn by the device will be more than the numbers specified in the current consumption tables. Electrical Specifications 90 |
