STM32H723ZGT6 LQFP-144 microcontroller ST original stock

describe

The STM32H723xE/G device is based on high-performance Arm ® Cortex ®- The m7 32-bit RISC core operates at a frequency of up to 550 MHz. Cortex ®- The M7 core has floating-point units (FPUs) and supports Arm ® Double precision (IEEE 754 compatible) and single precision data processing instructions and data types. The Cortex-M7 core includes a 32k byte instruction cache and a 32k byte data cache. The STM32H723xE/G device supports a complete set of DSP instructions and a memory protection unit (MPU) to enhance application security.

The STM32H723xE/G device includes high-speed embedded memory and 1m bytes of flash memory, up to 564 kilobytes of memory (including 192 kilobytes, plus 64 kilobytes of ITCM, plus 128 kilobytes of AXI, 128 kilobytes of DTCM, 48 kilobytes of 48 bytes of AHB, and 4 kilobytes of backup memory), as well as extensive enhanced I/O and peripheral connections to the APB bus, AHB bus, 2x32 bit multi AHB bus matrix, and support for internal multi-layer AXI interconnection and external memory access. In order to improve the robustness of the application, all memory has error code correction (one correction, two error detections).

These devices are embedded with peripherals that allow for mathematical/arithmetic function acceleration (CORDIC coprocessors for trigonometric functions, filter functions for FMAC units). All devices provide 3 ADCs, 2 DaCs, 2 operational amplifiers, 2 ultra-low power comparators, 1 low-power RTC, 4 general-purpose 32-bit timers, 12 general-purpose 16 bit timers, including two PWM timers for motor control, 5 low-power timers, and a true random number generator (RNG). This device supports an external signal modulator (DFSDM) with four digital filters. They also have standard and advanced communication interfaces.

The STM32H723xE/G device operates in an ambient temperature range of -40 to+85 ° C, with a power supply temperature range of 1.62 to 3.6 V. By using an external power supply main (see section 3.7.2: Power Supply Main) and connecting the PDR-ON pin to VSS, the power supply voltage can be reduced to 1.62 V. Otherwise, after enabling the embedded power supply voltage detector, the power supply voltage must remain above 1.71 V.

USB dedicated power input to allow for larger power options. A comprehensive energy-saving mode allows for the design of low-power applications.

The STM32H723xE/G device has 100 to 144 needles/balls. The set of peripheral devices included varies with the selected device.
