The device offers one fast 14-bit ADC (2.5 Msps), one 12-bit ADC (2.5 Msps), two comparators, two operational
amplifiers, two DAC channels, an internal voltage reference buf
fer, a low-power RTC, four 32-bit general-purpose
timers, two 16-bit PWM timers dedicated to motor control, three 16-bit general-purpose timers, two 16-bit basic
timers, and four 16-bit low-power timers. The device supports a multifunction digital filter (MDF) with six filters
dedicated to the connection of external sigma-delta modulators. Another low-power digital filter dedicated to audio
signals is embedded (ADF), with one filter supporting sound-activity detection.
The device embeds a Chrom-ART accelerator dedicated to graphic applications, and mathematical accelerators
(a trigonometric functions accelerator plus a filter mathematical accelerator). In addition, up to 24 capacitive
sensing channels are available.
The device also features standard and advanced communication interfaces such as: four I
2
Cs, three SPIs,
three USARTs, two UARTs, one low-power UART, two SAIs, one digital camera interface (DCMI), two SDMMCs,
one FDCAN, one USB OTG full-speed, one USB Type-C /USB Power Delivery controller, and one generic
synchronous 8-/16-bit PSSI (parallel data input/output slave interface). The device operates in the -40 to +85°C
(+105°C junction) and -40 to +125°C (+130°C junction) temperature ranges from a 1.71 to 3.6 V power supply.
A comprehensive set of power-saving modes allows the design of low-power applications. Many peripherals
(including communication, analog, timers, and audio peripherals) can be functional and autonomous down to stop
mode with direct memory access, thanks to low-power background autonomous mode (LPBAM).
Some independent power supplies are supported like an analog independent supply input for ADC, DACs,
OPAMPs and comparators, a 3.3 V dedicated supply input for USB and up to 14 I/Os, that can be supplied
independently down to 1.08 V. A VBAT input is available for connecting a backup battery in order to preserve the
RTC functionality and to back up 3232-bit registers and 2-Kbyte SRAM. The devices offer eight packages from 48
to 169 pins.
1.6.2.2 BlueNRG-M2
The BlueNRG-M2 is a Bluetooth
®
Low Energy system-on-chip application processor certified module, compliant
with BT specifications v5.2 and BQE qualified.
The module supports multiple roles simultaneously and can act at the same time as a Bluetooth
®
Low Energy
master and a slave device.
It is based on the BlueNRG-2
system-on-chip and embeds the entire Bluetooth
®
Low Energy stack and protocols.
The BlueNRG-2 module provides a complete RF platform in a tiny form factor. The integrated radio, the
embedded antenna, and the high frequency oscillators offer a certified solution to optimize the time-to-market
of the final applications.
• Operating band: 2402 MHz to 2480 MHz
• Channel spacing: 2 MHz
• RF power: +5 dBm

1.6.2.3 MXCHIP EMW3080
The MXCHIP EMW3080 module is an embedded device for Internet wireless connectivity. The module uses the
SPI2 interface of the STM32U585AI to communicate with the MCU.
This Wi-Fi module requires no operating system and has a completely integrated TCP/IP stack that requires only
A
T commands to establish the connection.
