The latest announcement of Polar Ocean Semiconductor is based on 32-bit ARM ®  Cortex ®- Industrial-grade standard APM32S103 series MCU with M3 core. This series of new products, as APM32F103 series iterative products, increase production line resources and improve the supply chain; Compared with the APM32F103 series, the APM32S103 series expands the internal integrated SRAM storage capacity to 36KB, increases the internal data storage space during the user program operation to improve the data exchange ability, and the QSPI communication peripheral can support a maximum rate of 4 * 18MHz.

The new APM32S103 product adheres to the design concepts and product production standards of APM32 MCU with high performance, high stability and high reliability, and has enhanced peripheral functions, which can meet the requirements of industrial product performance standards. Users can conduct product development and design in a variety of automatic control system applications, such as automatic control, electric equipment, security system, automotive electronics and other application fields.

APM32S103 enhances the standard performance of the chip, and can cover the APM32F103 series of products on the hardware pins and software. The main operating frequency can reach 96MHz, the operating voltage range is 2.0V~3.6V, and the operating temperature range can cover - 40 ℃~+105 ℃, meeting the standard requirements of commercial and industrial environmental temperature.

Rich on-chip resources bring more adaptive options for user application scenarios with standard functions and high reliability; At the same time, an FPU coprocessing unit dedicated to floating-point operations is built in and hung on the AHB bus, which can quickly process more complex floating-point operations, such as the decoding algorithm of the scanning gun, PID algorithm, fast Fourier transform, etc., to speed up the system processing capacity.

1. High integration

Integrate on-chip resources such as high-precision timers, analog peripherals and communication interfaces to help improve the product's diversified control and extensive connectivity functions, and meet more development and application needs of users.

2. Rich on-chip resources

Built-in 2 sets of CAN buses, supporting the simultaneous independent operation of CAN and USB; The configuration of the "dual CAN" module ensures the communication reliability and helps to improve the communication efficiency; Built-in 2 12-bit ADC, with a maximum of 16 external channels and 2 internal channels to realize dynamic high-precision real-time sampling; A temperature sensor is built in. The voltage generated by the sensor changes linearly with the temperature. The voltage value can be converted into temperature through ADC.

3. Reliable safety performance

Built-in power-on reset and power-off reset functions; It is equipped with a configurable voltage detection template to monitor the working voltage of the system in real time; Various timers are integrated internally to effectively reduce system risk; It has 96 unique device IDs to help customers customize regional product sales strategies.

4. Low power consumption

It supports three low power consumption modes: sleep, shutdown and standby. Users can configure different power consumption modes according to actual application requirements to minimize energy consumption and improve efficiency.

APM32S103 series MCU can be widely used in commercial or industrial control applications such as industrial instruments, building control, security systems, printing equipment, intelligent light control, automotive instruments, etc. It provides four packages, QFN36 and LQFP48/64/100, to meet the design requirements of users in different scenarios and improve system integration.
