x100y

X100Y is a family of low-power 32-bit microcontrollers designed for embedded systems. Developed by Crescent Electronics, the X100Y line was introduced in the early 2020s to target Internet of Things applications where energy efficiency and security are important. The family uses a 32-bit RISC core, with configurations that typically offer 256 KB to 1 MB of flash memory and 64 KB to 256 KB of RAM, though exact specifications vary by model. Peripherals commonly include UART, SPI, I2C, multiple timers, PWM outputs, and a multi-channel ADC, along with options for capacitive touch sensing.

Security and reliability are central features. Many X100Y variants include a hardware cryptographic engine that supports AES-128/256 and hashing, secure boot, and encrypted communications, making the devices suitable for deployments that require data protection and integrity. The platform also emphasizes robust power management, offering multiple sleep modes and dynamic voltage and frequency scaling to maximize battery life in portable or remotely powered sensors.

Package and environmental ranges vary to meet different use cases. Options span from compact 4x4 mm QFN to 7x7 mm LQFP footprints, with industrial temperature variants available for harsher operating environments. Development support is provided through common toolchains such as GCC, Keil, and IAR, along with official evaluation boards and a lightweight software stack that includes a real-time operating system and middleware for connectivity.

Typical applications encompass wearable devices, home automation sensors, environmental monitoring, and portable medical devices. The X100Y line is recognized for balancing computational performance, low power demand, and built-in security, situating it as a competitive option in the contemporary embedded MCU market.
