Cypress adds M0+ and M4-core MCUs to ARM portfolio

November 23, 2015 // By Graham Prophet
With two additions to its range of ARM Cortex based microcontrollers, Cypress Semiconductor is addressing ultra-low-power internet of things applications with an energy-efficient Cortex-M0+ series: and safety-critical industrial systems and home appliances with its FM4 family

In the efficient FM0+ range of Cortex-M0+ core parts, the FM0+ S6E1B-Series and S6E1C-Series microcontrollers (MCUs) deliver Cortex-M3/M4-class peripherals at 40 µA/MHz active current consumption budget, claiming the best combination of performance, efficiency and integrated peripherals for Cortex-M0+-based MCUs. The S6E1B-Series features the largest memory size for a Cortex-M0+ device and supports reliable and secure machine-to-machine (M2M) communication for the Internet of Things, while the S6E1C-Series is optimised for wearables and a range of ultra-low-power, battery-powered products.

The processing and flash architecture of Cypress FM0+ MCUs is optimised for high-efficiency, enabling the family to achieve 35 µA/CoreMark score (CoreMark, EEMBC). 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 560 kB of flash, 64 kB SRAM and 102 GPIOs for the S6E1B-Series. With their fast wake-up from standby modes, the FM0+ MCUs optimise power savings by remaining in low-power states for longer durations before quickly switching back to active modes. The FM0+ portfolio includes communication interfaces with AES hardware encryption, a rich set of digital and analog peripherals and a high-accuracy internal crystal oscillator to enable crystal-less communication and reduced bills-of-materials cost— in small QFN and QFP packages sampling now, and an even smaller, 6.4 mm² wafer-level chip scale package (WLCSP) available in the first quarter of 2016.

The Cypress FM0+ MCU portfolio offers:

A 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.

Analogue peripherals including an 8-channel, 1 Msps, 12-bit SAR ADC, a 1% high-precision crystal oscillator and an LCD controller with voltage boost.
