Engicam Launches Compact STM32 Based SOM for Secure IoT Applications

MicroGEA is an STM32-based compact System-on-Module (SoM) from Engicam. It is designed with the latest STM32MP135 microprocessors with Arm Cortex-A7 compute core. It also features a dedicated LCD-TFT display interface, a 16-bit parallel camera interface, and dual Ethernet ports. MicroGEA boards are designed for various applications like industrial automation, IoT, wearables, and embedded computing.

The STM32MP135 is a 1GHz 32-bit Arm Cortex-A7 processor with 32Kb L1 and 128Kb L2 cache. Referencing the STM32MP135 datasheet, it has two ADCs, ten 16-bit timers, two 32-bit timers, two PWM timers, a random number generator, a low-power RTC, and a secured cryptographic cell. Additionally, it supports security features such as TrustZone peripherals and tamper pins.

Besides that, this micro has an LCD-TFT controller with 4-bit color depth and a WXGA resolution of 1366 × 768 at 60 FPS. The STM32MP135 microcontroller also has a watchdog timer, a cryptographic engine, and a random number generation. Additionally, it supports CoreSight trace and debug capabilities. Coupled with 3072-bit fuses, including a unique ID, it forms a comprehensive solution for wearables and low-power applications.

Talking about supported protocols, this controller includes 2x SPI, 4x UART, 2x USART, 2x CAN, 2x I2C, 2x Analog, 2x SD/MMC, and multiple GPIOs.
