Table 5: GPIO recommended usage for module identify some GPIO that have recommended usage guidelines to maximize radio performance in an application. Table 5: GPIO recommended usage for module Recommended usage Low drive, low frequency I/O only. Included GPIO P22, P23, P24, P25, P26, P27, P28, P29, P30, P31. 2 NFC antenna pins Two physical pins can be configured either as NFC antenna pins (factory default), or as GPIOs, as shown below. NFC pad name GPIO NFC1 P09 NFC2 P10 When configured as NFC antenna pins, the GPIOs on those pins will automatically be set to DISABLE state and a protection circuit will be enabled preventing the chip from being damaged in the presence of a strong NFC field. The protection circuit will short the two pins together if voltage difference exceeds approximately 2V. For information on how to configure these pins as normal GPIOs, see NFCT — Near field communication tag on page 416 and UICR — User information configuration registers on page 54. Note that the device will not be protected against strong NFC field damage if the pins are configured as GPIO and an NFC antenna is connected to the device. The pins will always be configured as NFC pins during power-on reset until the configuration is set according to the UICR register. These two pins will have some limitations when configured as GPIO. The pin capacitance will be higher on these pins, and there is some current leakage between the two pins if they are driven to different logical values. To avoid leakage between the pins when configured as GPIO, these GPIOs should always be at the same logical value whenever entering one of the device power saving modes.

SAADC - BLE0305C2P Bluetooth Module Data Sheet Successive approximation analog-todigital converter 8.1. Reference The ADC can use two different references, controlled in the REFSEL field of the CH[n].CONFIG register. These are: • Internal reference • VCC as reference The internal reference results in an input range of ±0.6 V on the ADC core. VCC as reference results in an input range of ±VCC/4 on the ADC core. The gain block can be used to change the effective input range of the ADC. Input range = (+/- 0.6 V or +/-VDD/4)/Gain For example, choosing VCC as reference, single ended input (grounded negative input), and a gain of 1/4 the input range will be: Input range = (VCC/4)/(1/4) = VCC With internal reference, single ended input (grounded negative input), and a gain of 1/6 the input range will be: Input range = (0.6 V)/(1/6) = 3.6 V The AIN0-AIN7 inputs cannot exceed VCC, or be lower than GND. 8.2. Acquisition time To sample the input voltage, the ADC connects a capacitor to the input. For illustration, see Figure 103: Simplified ADC sample network on page. The acquisition time indicates how long the capacitor is connected, see TACQ field in CH[n].CONFIG register. The required acquisition time depends on the source (Rsource) resistance. For high source resistance the acquisition time should be increased, see Table 89: Acquisition time on page. Figure 103: Simplified ADC sample network Table 89: Acquisition time TACQ [μs] Maximum source resistance [kOhm] 10 40 10 100 15 200 20 400 40 800 8.3. Limits event monitoring A channel can be event monitored by configuring limit register CH[n].LIMIT. If the conversion result is higher than the defined high limit, or lower than the defined low limit, the appropriate event will get fired. http://www.jinoux.com +86-23-68798999 Page 10 of 18 ChongQing JINOU Science & Technology BLE0305C2P Bluetooth Module Data Sheet Figure 104: Example of limits monitoring on channel 'n' Note that when setting the limits, CH[n].LIMIT.HIGH shall always be higher than or equal to CH[n].LIMIT.LOW . In other words, an event can be fired only when the input signal has been sampled outside of the defined limits. It is not possible to fire an event when the input signal is inside a defined range by swapping high and low limits. The comparison to limits always takes place, there is no need to enable it. If comparison is not required on a channel, the software shall simply ignore the related events. In that situation, the value of the limits registers is irrelevant, so it does not matter if CH[n].LIMIT.LOW is lower than CH[n].LIMIT.HIGH or not. 8.4.

For example, sampling at 4kHz gives a sample period of 250μs. The average current consumption would then be: Figure 106: ADC INL vs Output Code **a Digital output code at zero volt differential input. **33 When tACQ is 10us or longer, and if DC/DC is active, it will be allowed to work in refresh mode if no other resource is requiring a high quality power supply from 1V3. If tACQ is smaller than 10us and DC/DC is active, refresh mode will not be allowed, and it will remain in normal mode from the START task to the STOPPED event. So depending on tACQ and other resources' needs, the appropriate base current needs to be taken into account. **b Does not include temperature drift **34 Maximum gain corresponds to highest capacitance. http://www.jinoux.com +86-23-68798999 Page 12 of 18 ChongQing JINOU Science & Technology BLE0305C2P Bluetooth Module Data Sheet Figure 107: ADC DNL vs Output Code Figure 108: FFT of a 2.8 kHz sine at 200 ksps () http://www.jinoux.com +86-23-68798999 Page 13 of 18 ChongQing JINOU Science & Technology BLE0305C2P Bluetooth Module Data Sheet 9.

Solder Profiles The soldering profile depends on various parameters necessitating a set up for each application. The data here is given only for guidance on solder re-flow. There are four zones: 1.Preheat Zone - This zone raises the temperature at a controlled rate, typically 1-2.5°C/s. 2.Equilibrium Zone - This zone brings the board to a uniform temperature and also activates the flux. The duration in this zone (typically 2-3 minutes) will need to be adjusted to optimise the out gassing of the flux. 3.Reflow Zone - The peak temperature should be high enough to achieve good wetting but not so high as to cause component discoloration or damage. Excessive soldering time can lead to intermetallic growth which can result in a brittle joint. 4.Cooling Zone - The cooling rate should be fast, to keep the solder grains small which will give a longer lasting joint. Typical rates will be 2-5°C/s. 10.1. Solder Re-Flow Profile for Devices with Lead-Free Solder Balls Composition of the solder ball: Sn 95.5%, Ag 4.0%, Cu 0.5% Typical Lead-Free Re-flow Solder Profile Key features of the profile: Initial Ramp = 1-2.5°C/sec to 175°C±25°C equilibrium Equilibrium time = 60 to 180 seconds Ramp to Maximum temperature (250°C) = 3°C/sec max. Time above liquidus temperature (217°C): 45-90 seconds Device absolute maximum reflow temperature: 260°C Devices will withstand the specified profile. Lead-free devices will withstand up to three reflows to a maximum temperature of 260°C.
