After the fever of Embedded World, Atmel has flat lined this month with no changes to its portfolio.


Freescale’s after-Embedded-World-fever has not come down a bit with a range of announcements last month.
The first announcement focused on the low end with the Kinetis KE02 now 40 MHz, KE04 48 MHz and KE06 48 MHz clearly targeting 8 and 16 bit incumbents. EMC and ESD protection functionality was increased for robust noise immunity and compliance with industrial-grade reliability and temperature requirements. Here are highlights for the new products:

  • Cortex-M0+ 40/48 MHz
  • 2.7-5.5V -40/+105C
  • Up to 128k Flash / 16k RAM / 256 B EEPROM
  • Prices range from $0.45 to $1.78

The Freescale Freedom dev boards are available at $12.95 for the KE02Z40M,KE04Z and KE06Z.

29 Kinetis E devices were released.

Last but not least, Freescale unveiled the Kinetis V2, a refresh of the original Kinetis K with improved power efficiency.

The refresh includes the new K0 – no part number just yet, but sampling – and the K1x, K2x and K6x MCU families have been expanded.
It is impressive to see $0.79 /10ku for a Cortex M4 based MCU running at 100MHz!

The new members feature

  • Increased RAM size
  • crystal-less USB
  • Better enablement: SDK, mbed-enabled, low-cost dev platform Arduino compatible, and support software.

The V2 parts announced were actually captured last month, except for the MK22FN128VDC10 and MK22FN128VLL10.


For April fool’s day, NXP announced that it has expanded the number of devices rated for 105C. About a dozen products appeared with the J rating e.g. LPC1111JHN33/103. They all belong to the LPC1 Cortex M0 based family. More interesting is the release of the new LPC11E6x targeted for “Extreme Industrial Environments”. It is the second Cortex M0+ based family – after the LPC810M021FN8, albeit much beefed up.
The new LPC11E6x family is available in 3 memory and package variations. Two on-chip SCTimer/PWMs support advanced timing features. A SCTimer/PWM Cookbook provides examples to speed up the learning curve.

  • 50 MHz
  • Up to 4 kB EEPROM, 256 kB Flash, and 36kB RAM
  • 2Msps, 12-channel, 12-bit ADC and temperature sensor
  • 2 SCTimer/PWMs, 4 multi-purpose timers, and RTC
  • 2x I2C, 2x SPI, up to 5 USARTs, up to 80 GPIO pins
  • DMA controller, CRC engine
  • ROM drivers for Power Profiles
  • Software- and tool-compatible with existing LPC11U/Exx and LPC134x parts

The LPC11E6x has now 3 products, available now, with distribution pricing starting at US $2.03/10k. The LPC11U6x LPCXpresso board is available now.
Finally, the LPC1768UK was introduced. It is a WLCSP-100 version of the current LPC1768 already available in BGA or LQFP100.
Full PR


Same here for Renesas with another flat line following last month’s announcement of the RX64

There has been a number of “un”announcements at SLAB recently, most likely given the recent acquisition of Energy Micro.
The portfolio price (EFM and SiM3) is stable this month.

ST Microelectronics

The apparent PR calm at ST last month did nothing for us to notice a few changes in the portfolio.
The STM32F0 added a few parts (STM32F051 and 072) while the new Cortex-M0+ based STM32L052/3 grew a few parts as well.
Finally, the STM32L100 (Cortex M3) saw a revision A come out. A quick comparison of the datasheets reveals adjustments to the power consumption. Here is the summary (original / rev A):

  • 0.30 / 0.28 uA Standby mode (2 wakeup pins)
  • 0.90 / 1.11 uA Standby mode + RTC
  • 0.57 / 0.44 uA Stop mode (16 wakeup lines)
  • 1.20 / 1.38 uA Stop mode + RTC
  • 9.0 / 10.9uA Low-power Run mode
  • 214 / 185 uA/MHz Run mode

Texas Instruments

TI has flatlined on the Tiva this month as we expect it to slowly give up on this product line.
