Page 6: System Description
MAX-M10M is cost and power optimized for designs where a SAW ﬁlter and an LNA are integrated in the external active antenna. It works in a wide main supply voltage range of 1.8 - 5 V with an extremely low power consumption of less than 10 mW in a 1 Hz cyclic tracking power save mode.

Page 9: Receiver Functionality
This section summarizes the basic receiver conﬁguration most commonly used. 2.1.1.1 Basic hardware conﬁguration The MAX-M10M receiver is conﬁgured with the default setting during the module production. The receiver starts up and is fully operational as soon as proper power supply, communication interfaces and antenna signal from the host application device are connected.
Page 10 10 receivers support three modes for the internal low-noise ampliﬁer (LNA): normal gain, low gain, and bypass mode. The MAX-M10M default is the normal-gain mode. With a high-gain external active antenna, the low-gain or the bypass mode can be used.
Page 11 CFG-UART1-*, CFG-UART1INPROT-*, CFG-UART1OUTPROT-* CFG-I2C-*, CFG-I2CINPROT-*, CFG-I2COUTPROT-*, CFG-TXREADY-* Table 3: Interface conﬁguration The UART baudrate in MAX-M10M is conﬁgured to 9600 baud which is diﬀerent to the ﬁrmware default. This ensures backwards compatibility with previous generations of u-blox MAX modules. 2.1.1.5 Message output conﬁguration The receiver supports two protocols for output messages: industry-standard NMEA and u-blox UBX.
Page 12 MAX-M10M - Integration manual Some messages, such as UBX-MON-VER, are non-periodic and will only be output as an answer to a poll request. The UBX-INF-* and NMEA-Standard-TXT information messages are non-periodic output messages that do not have a message rate conﬁguration. Instead they can be enabled for each communication interface via the CFG-INFMSG-* conﬁguration group.

If the velocity cannot be calculated with suﬃcient accuracy (for example, with bad signals) or if the absolute speed value is very low (under 0.1 m/s) then the course over ground value becomes...
Page 18: Augmentation Systems
SBAS signals can also be used for navigation, however they have low weighting and therefore only a minor impact on the navigation solution. For receiving correction data, the MAX-M10M automatically chooses the best SBAS satellite as its primary source. It will select only one since the information received from other SBAS satellites is redundant and could be inconsistent.
Page 19: Qzss Slas
Multiple QZSS SLAS signals can be received simultaneously. When receiving QZSS SLAS correction data, MAX-M10M will autonomously select the best QZSS satellite. The selection strategy is determined by the quality of the QZSS L1S signals, the receiver conﬁguration (test mode allowed or not), and the location of the receiver with respect to the QZSS SLAS coverage area.

CPU. Each protocol can be enabled on several interfaces at the same time with individual settings for, for example, baud rate, message rates, and so on. In MAX-M10M, several protocols can be enabled on a single interface at the same time.
Page 21: I2C
2.3.2 I2C The I2C protocol and electrical interface in MAX-M10M are fully compatible with Fast-mode of the I2C industry standard. The interface allows communication with an external host CPU or u-blox cellular modules with a maximum transfer rate of 400 kb/s.
Page 22 MAX-M10M - Integration manual Figure 6: I2C register layout 2.3.2.2 Read access types The host can choose one of the following two modes: • Random read access: the master ﬁrst reads the number of available bytes at the 0xFD and 0xFE before accessing the data at 0xFF.
Page 23 However, it can be extended by setting the CFG-I2C-EXTENDEDTIMEOUT conﬁguration item to true (see the MAX-M10M interface description [3]). By disabling the timeout, the receiver will only interrupt the data stream when the buﬀer is full. The buﬀer can store up to 4 kB and the time for an overﬂow event depends on the number of messages enabled.
Page 24: Pios
I2C pins are used for antenna supervisor functions. 2.3.3.1 RESET_N MAX-M10M provides a RESET_N pin to reset the receiver. The RESET_N pin is input-only with an internal pull-up resistor to V_IO and should be left open for normal operation. Driving RESET_N low for at least 1 ms will trigger a reset of the receiver.
Page 25 The LNA_EN signal can also be used as a part of antenna supervisor circuit to control an external LNA or antenna power supply. 2.3.3.5 EXTINT MAX-M10M supports external interrupts at the EXTINT pin. The EXTINT pin has a ﬁxed input voltage threshold with respect to V_IO. It can be used for functions such as accurate external Frequency...

An active antenna supervisor circuit uses the ANT_DETECT, ANT_OFF_N, and ANT_SHORT_N signals. The ANT_OFF_N signal is already enabled and assigned to the LNA_EN pin in MAX-M10M. The ANT_DETECT and ANT_SHORT_N signals can be assigned to any unused PIOs, which may require disabling the previous function of the PIOs.

The ANT_OFF_N signal is already enabled and assigned to the LNA_EN pin in MAX-M10M and the ANT_SHORT_N signal can be assigned to any unused PIO, which may require disabling the previous function of the PIO. To enable the reduced antenna supervisor, the ANT_SHORT_N signal must be enabled in the receiver conﬁguration.
Page 29 V_ANT is the same voltage level as V_IO. 2.4.1.3 Antenna voltage control - ANT_OFF_N The antenna voltage control is enabled by default in MAX-M10M with the conﬁguration item CFG- HW-ANT_CFG_VOLTCTRL set to true (1). The antenna status (as reported in UBX-MON-RF and UBX-INF-NOTICE messages) is not reported unless the antenna voltage control has been enabled.
Page 30 MAX-M10M - Integration manual If CFG-HW-ANT_CFG_PWRDOWN has been enabled previously (set to true), the polarity of the ANT_OFF_N signal will change to power down (disable) the antenna supply when a short is detected. After a detected antenna short, the reported antenna status will continue to be reported as a SHORT.

There are functions to monitor/detect certain security threats and report it to the host system.
Page 34: Power Save Mode
MAX-M10M - Integration manual downloads all the almanac data and acquires new signals as they become available during navigation. The tracking engine consumes less power than the acquisition engine. The current consumption is lower when a valid position is obtained quickly after the start of the receiver navigation, the entire almanac has been downloaded, and the ephemeris for each satellite in view is valid.
Page 35 MAX-M10M - Integration manual Figure 12: State machine 2.7.2.2 Acquisition timeout The receiver has internal, external, and user-conﬁgurable mechanisms that determine the time to be spent in acquisition state. This logic is put in place to ensure good performance and low power consumption in diﬀerent environments and scenarios. This collective logic is referred to as acquisition timeout.
Page 36 MAX-M10M - Integration manual 2.7.2.3 Cyclic tracking Power save mode cyclic tracking (PSMCT) operation is described in Figure PSMCT supports 1 Hz and 2 Hz navigation update rates. In addition, longer update periods from 2 s to 10 s are supported at 1 s steps.

Otherwise it enters the "Inactive for search" state and restarts after the conﬁgured search period (minus a startup margin). • Once the ONTIME is over, the "Inactive for update" state is entered and the receiver restarts according to the conﬁgured update grid deﬁned by GRIDOFFSET.

The receiver maintains time information and navigation data to speed up the receiver restart after backup or standby mode.

MAX-M10M - Integration manual When the receiver ﬁrst starts, it has no information about how these clock ticks relate to other time systems; it can only count time in 1 millisecond steps. However, as the receiver derives information from the satellites it is tracking or from aiding messages, it estimates the time that each 1-kHz clock tick takes in the time base of the chosen GNSS system.
