Caution: Class 2 ESD Sensitivity, JESD22−A114−B (2000 V)
Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. In some applications, VDDO can be higher than 2.1 V (maximum 3.3 V). In such cases, the user must set the VDDM voltage at a minimum
of 1.1 V
2. Electrical Specification may exceed listed tolerances when out of the temperature range 0 to 50°C
The tests were performed at 20°C with a 1.25 V supply voltage and 4.7 W series resistor to simulate a nominal hearing aid
battery. The system clock (SYS_CLK) was set to 5.12 MHz and an audio input sampling frequency of 16 kHz was used.
Parameters marked as screened are tested on each chip.

3. In order to be able to use a VBAT Min of 1.1 V, the following reduced operating conditions for the RSL10 should be observed:
− Maximum Tx power 0 dBm.
− SYSCLK ≤ 24 MHz.
− Functional temperature range limited to 0 − 50°C
The following trimming parameters should be used:
− VCC = 1.10 V
− VDDC = 0.92 V
− VDDM = 1.05 V, will be limited by VCC at end of battery life
− VDDRF = 1.05 V, will be limited by VCC at end of battery life. VDDPA should be disabled
RSL10 should enter in end−of−battery−life operating mode if VCC falls below 1.03 V. VCC will remain above 1.03 V if VBAT ≥ 1.10 V under
the restricted operating conditions described above.
4. Min VBAT = 1.05 V if RSL10 is disabled
