STM32F373xx Functional overview 3 Functional overview 3.1 ARM® Cortex®-M4 core with embedded Flash and SRAM The ARM Cortex-M4 processor is the latest generation of ARM processors for embedded systems. It was developed to provide a low-cost platform that meets the needs of MCU implementation, with a reduced pin count and low-power consumption, while delivering outstanding computational performance and an advanced response to interrupts.
Functional overview 3.3 STM32F373xx Embedded Flash memory All STM32F373xx devices feature up to 256 Kbytes of embedded Flash memory available for storing programs and data. The Flash memory access time is adjusted to the CPU clock frequency (0 wait state from 0 to 24 MHz, 1 wait state from 24 to 48 MHz and 2 wait states above). 3.
STM32F373xx Functional overview 3.7 Power management 3.7.1 Power supply schemes 3.7.2 • VDD: external power supply for I/Os and the internal regulator. It is provided externally through VDD pins, and can be 2.0 to 3.6 V. • VDDA = 2.0 to 3.6 V: – external analog power supplies for Reset blocks, RCs and PLL – supply voltage for 12-bit ADC, DACs and comparators (minimum voltage to be applied to VDDA is 2.4 V when the 12-bit ADC and DAC are used). • VDDSD12 and VDDSD3 = 2.2 to 3.
Functional overview 3.7.4 STM32F373xx Low-power modes The STM32F373xx supports three low-power modes to achieve the best compromise between low power consumption, short startup time and available wakeup sources: • Sleep mode In Sleep mode, only the CPU is stopped. All peripherals continue to operate and can wake up the CPU when an interrupt/event occurs. • Stop mode Stop mode achieves the lowest power consumption while retaining the content of SRAM and registers. All clocks in the 1.
STM32F373xx Functional overview Do not reconfigure GPIO pins which are not present on 48 and 64 pin packages to the analog mode. Additional current consumption in the range of tens of µA per pin can be observed if VDDA is higher than VDDIO. 3.10 Direct memory access (DMA) The flexible 12-channel, general-purpose DMA is able to manage memory-to-memory, peripheral-to-memory and memory-to-peripheral transfers.
Functional overview 3.12 STM32F373xx 12-bit analog-to-digital converter (ADC) The 12-bit analog-to-digital converter is based on a successive approximation register (SAR) architecture. It has up to 16 external channels (AIN15:0) and 3 internal channels (temperature sensor, voltage reference, VBAT voltage measurement) performing conversions in single-shot or scan modes. In scan mode, automatic conversion is performed on a selected group of analog inputs. The ADC can be served by the DMA controller.
STM32F373xx 3.13 Functional overview 16-bit sigma delta analog-to-digital converters (SDADC) Three 16-bit sigma-delta analog-to-digital converters are embedded in the STM32F373xx. They have up to two separate supply voltages allowing the analog function voltage range to be independent from the STM32F373xx power supply. They share up to 21 input pins which may be configured in any combination of single-ended (up to 21) or differential inputs (up to 11). The conversion speed is up to 16.
Functional overview 3.15 STM32F373xx Fast comparators (COMP) The STM32F373xx embeds 2 comparators with rail-to-rail inputs and high-speed output. The reference voltage can be internal or external (delivered by an I/O). The threshold can be one of the following: • DACs channel outputs • External I/O • Internal reference voltage (VREFINT) or submultiple (1/4 VREFINT, 1/2 VREFINT and 3/4 VREFINT) The comparators can be combined into a window comparator.

Functional overview 3.17 STM32F373xx Timers and watchdogs The STM32F373xx includes two 32-bit and nine 16-bit general-purpose timers, three basic timers, two watchdog timers and a SysTick timer. The table below compares the features of the advanced control, general purpose and basic timers. Table 5.
STM32F373xx 3.17.1 Functional overview General-purpose timers (TIM2 to TIM5, TIM12 to TIM17, TIM19) There are eleven synchronizable general-purpose timers embedded in the STM32F373xx (see Table 5 for differences). Each general-purpose timer can be used to generate PWM outputs, or act as a simple time base.
Functional overview 3.17.3 STM32F373xx Independent watchdog (IWDG) The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is clocked from an independent 40 kHz internal RC and as it operates independently from the main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog to reset the device when a problem occurs, or as a free running timer for application timeout management. It is hardware or software configurable through the option bytes.
STM32F373xx • Functional overview Reference clock detection: a more precise second source clock (50 or 60 Hz) can be used to enhance the calendar precision. The RTC clock sources can be: 3.19 • A 32.768 kHz external crystal • A resonator or oscillator • The internal low-power RC oscillator (typical frequency of 40 kHz) • The high-speed external clock divided by 32 Inter-integrated circuit interface (I2C) Two I2C bus interfaces can operate in multimaster and slave modes.

All USARTs interfaces are able to communicate at speeds of up to 9 Mbit/s.
STM32F373xx 3.21 Functional overview Serial peripheral interface (SPI)/Inter-integrated sound interfaces (I2S) Three SPIs are able to communicate at up to 18 Mbits/s in slave and master modes in fullduplex and half-duplex communication modes. The 3-bit prescaler gives 8 master mode frequencies and the frame is configurable to 8 bits or 16 bits. The hardware CRC generation/verification supports basic SD Card/MMC modes. The SPIs can be served by the DMA controller.
Functional overview 3.24 STM32F373xx Universal serial bus (USB) The STM32F373xx embeds an USB device peripheral compatible with the USB full-speed 12 Mbs. The USB interface implements a full-speed (12 Mbit/s) function interface. It has software-configurable endpoint setting and suspend/resume support. The dedicated 48 MHz clock is generated from the internal main PLL (the clock source must use a HSE crystal oscillator). 3.

STM32F373xx Package information Using the values obtained in Table 81 TJmax is calculated as follows: – For LQFP100, 46°C/W TJmax = 115 °C + (46°C/W × 98.8 mW) = 115 °C + 4.54 °C = 119.5 °C This is within the range of the suffix 7 version parts (–40 < TJ < 125 °C). In this case, parts must be ordered at least with the temperature range suffix 7 (see Section 8: Part numbering). Figure 44. LQFP64 PD max vs.
