Microchip expands its portfolio of MPU-based SOMs with SAM9X60D1G-SOM

As the embedded market continues to grow rapidly and evolve, developers are seeking to optimise product development, or they may need to transition from a microcontroller (MCU) to a microprocessor (MPU) to handle increased processing requirements.

To help developers with this transition and reduce design complexities Microchip has announced it has expanded its portfolio of microprocessors system-on-modules (SOMs) with the SAM9X60D1G-SOM ARM926EJ-S-based embedded MPU running up to 600 MHz. Software for the SAM9X60D1G-SOM is available with bare metal or RTOS support through MPLABHarmony3, or complete Linux mainlined distributions.

The SOM, based on the SAM9X60D1G System in Package (SiP), is a small 28mm × 28mm hand-solderable module that includes the MPU and DDR in a single package, along with power supplies, clocks and memory storage. The SAM9X60D1G-SOM is Microchip’s first SOM equipped with 4GB SLC NAND Flash to maximise memory storage of data in application devices, while the on-board DDR reduces the supply and price risks associated with memory chips. The small-form-factor SAM9X60D1G-SOM also includes an MCP16501 power management IC (PMIC), which simplifies the power design effort to a single 5V voltage rail to enable lower-power systems.

To offer the features an Ethernet-connected system might require, the SAM9X60D1G-SOM contains a 10/100 KSZ8081 Ethernet PHY and a 1KB Serial EEPROM with pre-programmed MAC address (EUI-48). Customers can further customise their design based on the level of security protection required such as secure boot with on-chip secure key storage (OTP), hardware encryption engine (TDES, AES and SHA) and True Random Generator (TRNG).

“With the SAM9X60D1G-SOM, designers can take advantage of a mid-level performance microprocessor and significantly reduce design complexities,” said Rod Drake, vice president of Microchip’s 32-bit MPU business unit. “This latest SOM provides customers a small-form-factor solution directly from Microchip and eases the logistics burden of separately procuring each of the six active components and numerous passives on the SOM.”

The SAM9X60D1G-SOM is the newest addition to the existing portfolio of MPU-based SOMs built using a common set of proven Microchip components to reduce design complexity and overall PCB costs. For example, because the complex devices are already routed on the SOM, customers can design their products using a low-cost, four-layer PCB.

The SOM and its components are backed by Microchip’s client-driven obsolescence practice of continuing to supply a product for as long as possible and while demand for the product exists. This is particularly important in today’s semiconductor climate of high demand and supply constraints.

 The SAM9X60D1G-SOM is designed for many MPU32 end applications across a variety of industries such as medical equipment, automotive telematics and infotainment systems, electric vehicles chargers, industrial and automation control and more. It is also particularly well-suited for products designed for providing computing capabilities with multiple communication interfaces that are qualified once and then customized for separate projects.

Development tools

Microchip provides both hardware and software development support for the SAM9X60D1G-SOM including the SAM9X60D1G Curiosity Evaluation Kit (CPN: EV40E67A) featuring three Linux distributions: BuildRoot, Yocto and OpenWRT. The bare-metal or RTOS-based systems are supported by MPLAB Harmony 3 embedded software framework, MPLAB X Integrated Development Environment (IDE) and MPLAB XC32 compiler.

Pricing and availability

The SAM9X60D1G-SOM (PN SAM9X60D1G-I/LZB) is available for $42.96 each in 5,000-unit quantities. To purchase, contact a Microchip sales representative, authorised worldwide distributor or Microchip’s Purchasing and Client Services website.
