ST tweaks the portfolio

2014
After the heat of new products and price changes, it looks like MCU manufacturers are taking a well deserved break this month. Well, maybe except for ST who showed 50+ new products.
Atmel
Although Atmel had no new product over the last 30 days, there was a sizable announcement for the maker community on May 15 where the Arduino Zero board was unveiled jointly with Arduino.
It is interesting to see that this new board is the first one to be based on the Cortex-M0+ family and the second Cortex-M based one. All the others are based on the ATMega family. The new board sports a ATSAMD21G18 running at 48 MHz with 256 kB of Flash and 32 kB of RAM.
Freescale has entered a cool off period after the frenzy of the last couple of months (KE02/4/6 announcements).
Only one product appeared, the MK22FN128VLH10 while the MK10DN512ZVMC10R was removed.
NXP
Not much change this month to the NXP portfolio
Same here for Renesas with another flat line following the announcement in March of the RX64.
SLAB continues to work on the portfolio realignment after the acquisition of Energy Micro in June last year.
The portfolio price (EFM and SiM3) is stable this month.
ST Microelectronics
Another interesting month at ST:
- The STM32F050 is slowly being phased out with all but one part in NRND. That one (STM32F050G6) is in evaluation…
- Over 53 products were made public this time, here is a recap:
- F031: higher temperature version of existing parts
- F100R8H: higher temperature version of existing parts
- F301: new family in the analog/metering family
- F302, 303: smaller Flash sizes in existing family: 32 and 64 kB
- F358: new family focused on analog and metering. Sports 4 analog comparators, 4 ADC, 2 DAC, 72 MHz, and 256 kB Flash for now
- F378: similar to 358 with more timers, sigma delta ADC, 256 kB Flash for now
- F429: now offering down to 512 kB Flash, with additional packages
- L051/052: now with 36 pins
Texas Instruments
TI has done a new silicon revision of its Tiva 129 samples, maybe for existing customers?
In the MSP430 family, 14 new products were uncovered in the 6 family (USB+LCD) as well as 2 series and FRAM.
New Freescale KE and Kinetis V2

Atmel
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.
NXP
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.

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