PublishTime： 2023-04-15 Article Source：Geehy Semiconductor News

Geehy Semiconductor announced the new high-performance, high-security APM32F405/415（APM32F415） industrial-grade MCUs based on the Arm^® Cortex^®-M4 core, featuring high capacity, wide temperature range, high stability, high reliability, and high integration. The two new products came with rich peripherals and can be widely used in industrial control, instrument & apparatus, medical equipment, power electronics, etc.

Geehy focuses on and continues to deepen cooperation with all relevant manufacturers in terms of product requirements, definition, iteration and upgrade, and application. Currently, APM32 series industrial-grade MCUs have been recognized by industry TOP customers in the field of industrial automation. APM32F405/415 series will continue to focus on industrial control and new energy markets, bringing customers a more cost-effective option.

APM32F405/415 Series MCUs Core Advantages:

1. Larger Capacity & Faster Storage

Based on Arm^® Cortex^®-M4 core, high-performance CPU computing, operates at a frequency of 168MHz, supports single-precision FPU and enhanced DSP instructions; built-in 1024KB Flash, 192+4KB SRAM, while supporting a variety of external memory such as PSRAM, NORFlash, NANDFlash, etc.

2. High Stability

With the advantage of high-end signal chain design, the new series meets the ADC accuracy requirements within the full industrial-grade temperature range of -40℃~+105℃, achieving dynamic high-precision real-time sampling, high efficiency, and low latency, and ensuring stable operation under complex temperature scenarios.

3. High Security

APM32F405/415 series has adopted a built-in true random number generator and HASH algorithm. The APM32F415 series supports AES, DES, and TDES encryption standards, as well as RNG, SHA-224, SHA-256, MD5, and other secure hash algorithms to effectively ensure product information security. The power supply voltage ranges from 1.8V to 3.6V. Power-on reset (POR), power-down reset (PDR), and programmable voltage detector (PVD) are equipped to enhance chip power management reliability.

4. Rich On-Board Resources

Built-in 12-bit precision ADC with a sampling rate of 2.4 MSPS, supporting up to 24 external channels; with two 12-bit DAC output channels, each with multiple triggers to trigger conversion. On top of supporting full-speed and high-speed USB, a new on-chip integrated PHY high-speed OTG HS2 is added to help users save hardware design costs. A built-in RTC supports a calendar clock and two programmable alarm interrupts for an automatic wake-up in low-power mode; up to 114 I/Os, all of which can be mapped to external interrupt vectors.

5. Low Power Consumption

Three low-power modes of sleep, stop, and standby minimizes energy consumption and improves efficiency, users can choose according to the actual application requirements to meet the needs of low-power scenarios to the greatest extent.
