Product Description

        APM32F103x4x6x8xB/APM32E103xB series chip is based on ARM ® architecture ®- M3 kernel 32 bit microprocessor, Max working frequency 96 MHz. The built-in AHB high-performance bus, combined with high-speed memory and DMA, enables rapid data processing and storage. It is equipped with an advanced APB peripheral bus, which expands a rich range of peripherals and enhanced I/O, ensuring rapid connection and flexible control. The chip is equipped with a powerful FPU floating-point operation processing unit inside, supporting single-precision data processing instructions and data types.

       Equipped with up to 128K bytes of flash memory and 20K bytes of SRAM memory, all models include 2 12-bit ADCs, 3 general-purpose 16-bit timers, 1 advanced control timer and 1 temperature sensor. It also includes standard and advanced communication interfaces : 2 I²C interfaces, 2 SPI interfaces, 1 QSPI interface, 3 USART interfaces, 1 USB2.0FS interface and 1 CAN2.0B interface. USB and CAN CAN work independently simultaneously.

       The working voltage is 2.0V to 3.6V, and there are two types of operating temperature ranges to choose from: -40°C to +85°C and -40°C to +105 °C. LQFP100 / LQFP64 LQFP48 / QFN36 four different forms of packaging, different packaging of peripherals and I/O configuration is different.

Absolute max rating value

       If the absolute max rated value given in the max rated voltage characteristic and the max rated current characteristic is applied to the device, it may cause permanent damage to the device. Here, only the maximum load that can be endured is provided, and it does not mean that the functional operation of the device is normal under this condition. Long-term operation of the device under max conditions will affect its reliability.
