STM32F207ZGT7 Description

The high-performance Arm? Cortex?-M3 32-bit RISC core, which operates at a frequency of up to 120 MHz, is the foundation of the STM32F207ZGT7 series. The family has a wide range of upgraded I/Os and peripherals connected to two APB buses, three AHB buses, and a 32-bit multi-AHB bus matrix, along with high-speed embedded memories (Flash memory up to 1 Mbyte, up to 128 Kbytes of system SRAM, up to 4 Kbytes of backup SRAM).

The devices additionally include an adaptive real-time memory accelerator (ART Accelerator?), which enables program execution from Flash memory with performance similar to zero wait states at CPU frequencies up to 120 MHz. The CoreMark? benchmark has been used to certify this performance.

Three 12-bit ADCs, two DACs, a low-power RTC, 12 general-purpose 16-bit timers, including two PWM timers for motor control, and two general-purpose 32-bit timers are all provided by the devices. a genuine number generator (RNG). Standard and cutting-edge communication interfaces are also included. An SDIO, an improved Flexible Static Memory Control (FSMC) interface, and a camera interface for CMOS sensors are examples of new, advanced peripherals. These devices are available in packages with at least 100 pins. The gadgets also include common peripherals.
