ELECTRICAL SPECIFICATIONS
The majority of these characteristics are based on controlling and conditioning the tests using the TiWiBLE control software application. Other control conditions may require these values to be recharacterized by the customer.

1. Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device and are not
covered by the warranty. These are stress ratings only and functional operation of the device at these or any other
conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolutemaximum-rated conditions for extended periods may affect device reliability.
2. All parameters are measured as follows unless stated otherwise: VDD_IN=1.8V, VDDIO_1.8V=1.8V,
VDD_LDO_CLASS1P5=3.6V
3. Analog pins: XTALP, XTALM, RFIOBT, DRPWRXBM, DRPWRXBP, DRPWTXB, and also FMRFINP, FMRFINM,
FMRFINM, FMAUDLIN, FMAUDRIN, FMAUDLOUT, FMAUDROUT
4. The following signals are from the VBAT group, PMS_VBAT and VDD_LDO_CLASS1P5 (if BT class 1.5 direct VBAT is
used).
5. Maximum allowed depends on accumulated time at that voltage; 4.8V for 7 years lifetime, 5.5V for 6 hours cumulative.
6. The device can be reliably operated for 5,000 active-WLAN cumulative hours at T
of 85oC.

WLAN POWER-UP SEQUENCE
The following sequence describes device power-up from shutdown. Only the WLAN Core is enabled; the
Bluetooth and FM cores are disabled.
Figure 1 TiWi-BLE Power-up Sequence Requirements
1. No signals are allowed on the IO pins if no IO power is supplied, because the IOs are not 'failsafe’.
Exceptions are CLK_REQ_OUT, SLOWCLK, XTALP, and AUD_xxx, which are failsafe and can
tolerate external voltages with no VDDS and DC2DC".
2. VBAT, VIO, and SLOWCLK must be available before WL_EN.
3. T
wakeup = T1 + T2
The duration of T1 is defined as the time from WL_EN=high until Fref is valid for the SoC. T1=~55ms
The duration of T2 depends on:
Operating system
– Host enumeration for the SDIO/WSPI
– PLL configuration
– Firmware download
– Releasing the core from reset
– Firmware initialization
