Cypress Introduces the Industry’s Most Energy-Efficient ARM Cortex-M0+ MCUs for Ultra-Low-Power Internet of Things Applications

New FM0+ Series Delivers Best Combination of Performance and Power Consumption with High Peripheral Integration in Small Form-Factor Packages

SAN JOSE, Calif., November 18, 2015 – Cypress Semiconductor Corp. (Nasdaq: CY), a global leader in embedded systems solutions, today introduced two series in its highly efficient FM0+ portfolio of Flexible Microcontrollers based on the ARM® Cortex®-M0+ core. The new FM0+ S6E1B-Series and S6E1C-Series microcontrollers (MCUs) deliver Cortex-M3/M4-class peripherals at a low, 40µA/MHz active current consumption budget—providing the industry’s best combination of performance, efficiency and integrated peripherals for Cortex-M0+-based MCUs. The S6E1B-Series features the industry’s largest memory size for a Cortex-M0+ device and supports highly reliable and secure machine-to-machine (M2M) communication for the Internet of Things, while the S6E1C-Series is optimized for wearables and a wide range of ultra-low-power, battery-powered products. More information on the FM0+ portfolio is available at

The processing and flash architecture of Cypress FM0+ MCUs is optimized for high-efficiency, enabling the family to achieve an industry-best 35µA/CoreMark® score. CoreMark, which was developed by the Embedded Microprocessor Benchmark Consortium (EEMBC®), benchmarks the performance of a processor core and its memory subsystem and enables quick comparisons between processors. The FM0+ MCUs offer a memory and I/O footprint typically featured only in higher-end MCUs with Cortex-M3 or Cortex-M4 cores, with up to 560KB of flash, 64KB SRAM and 102 GPIOs for the S6E1B-Series. With their fast wake-up from standby modes, the FM0+ MCUs optimize power savings by remaining in low-power states for longer durations before quickly switching back to active modes. The FM0+ portfolio features industry-leading peripheral integration that includes communication interfaces with AES hardware encryption, a rich set of digital and analog peripherals and a high-accuracy internal CR oscillator to enable crystal-less communication and reduced bills-of-materials cost—all in small QFN and QFP packages sampling today, and an even smaller, 6.4mm2 wafer-level chip scale package (WLCSP) available in the first quarter of 2016.

"Smart, sensor-based Internet of Things applications, wearables and healthcare equipment require secure and reliable M2M communication, increasing demand for solutions with ultra-low power consumption and high peripheral integration," said John Weil, vice president of marketing for the MCU business unit at Cypress. "Our new FM0+ MCUs are designed to meet this challenge with a unique combination of integrated peripherals and an ultra-low-power ARM Cortex-M0+ core."

Key Features and Benefits of the Cypress FM0+ MCU Portfolio

The Cypress FM0+ MCU portfolio delivers leading performance with:

  • A unique, 64-channel descriptor-based direct memory access (DMA) controller to efficiently move data between peripherals and RAM without any CPU intervention
  • Up to 6-channel multi-function serial interfaces (UART/I2C/SPI), a 1-channel USB Host or Device, AES encryption, a 2-channel HDMI-CEC, a 2-channel Smart Card interface and I2S for digital audio.
  • Analog peripherals including an 8-channel, 1Msps, 12-bit SAR ADC, a 1% high-precision CR oscillator and an LCD controller with voltage boost.

The Cypress FM0+ S6E1B-Series and S6E1C-Series MCUs are now sampling, with production expected in the fourth quarter of 2015.

Cypress’s MCU Portfolio
The Cypress-Spansion merger created a $2 billion global leader in MCUs and specialized memories for embedded systems with a significant focus on automotive, industrial and home appliance applications. The merger significantly expanded Cypress’s portfolio of embedded processors, leveraging a broad range of strong, complementary, ARM®-based MCUs and PSoC programmable system-on-chip solutions. The breadth of Cypress’s portfolio enables one-stop MCU selection and design plus fast, easy migration from the most cost-effective solutions to those with industry-leading performance.
