Precision32 Microcontroller Family by Silicon Labs

Semiconductor Vendor with ARM Processor RTL license from ARM

Product Description

Silicon Labs' Precision32™ 32-bit microcontroller family is engineered to make the developer's job easier. The Precision32 MCUs provide a highly integrated and flexible architecture, a rich peripheral set and low power consumption. To ease development, Silicon Labs offers an Eclipse-based development suite including a full compiler, debugger and AppBuilder rapid prototyping utility at no charge. Based on the ARM® Cortex™-M3 core, the new Precision32 SiM3U1xx and SiM3C1xx MCUs include USB and non-USB devices with 32–256 kB Flash, 8–32 kB RAM and 40–92 pin packages.

The Precision32 family’s analog peripherals are specified and tested to operate over temperature and voltage (down to 1.8 V). In fact, these high-performance analog peripherals are so reliable they can replace standalone analog components. Moreover, the Precision32 analog peripherals are highly configurable, enabling developers to simplify their designs and optimize performance for a wide variety of embedded applications.

Silicon Labs engineered the Precision32 family to achieve industry-leading power efficiency in both active and sleep modes. The MCUs leverage Silicon Labs’ state-of-the-art, patented low-power design technologies to achieve power reductions within every block of the MCU design, resulting in up to 33 percent lower active current (22 mA at 80 MHz or 275 µA/MHz) and 100 times lower sleep current (0.35 µA with RTC enabled and 4 kB of RAM retention) than competing 32-bit solutions. Numerous power modes and clocking options enable developers to optimize their embedded designs for the lowest power at a given performance level.

Production quantities of Silicon Labs’ Precision32 MCUs are available now with flash sizes scaling from 32 to 256 kB and in five leaded and leadless package types, ranging from a 6 mm x 6 mm QFN-40 for space-sensitive applications up to an LGA-92 for maximum I/O configurations.
