What a RAM feat at Microchip!

What a feat for a microcontroller: 32 MB of DDR2 SDRAM were integrated in to the latest Microchip PIC32MZ DA. With rich UI as a target, we can bet they will collide with lower end application processors. NXP showed some goodness when releasing the MKV with bundled motor control. We also had a few sad news with the disappearance of a few families… Happy 4th of July for our US readers!
Only a few changes at Atmel this month, around tray versions of existing parts.
No change.
Infineon is retiring 31 products, all revision 1 in the XMC4xxx family.
Microchip enriched its PIC32MM portfolio with 47 parts, pushing the flash size up to 128 and 256kB of Flash. The PIC32MZ DA grew too, by 80 parts adding to the existing 1 and 2 MB of Flash. The PIC32MZ DA series integrates a graphics controller (up to SXGA support), a graphic processor to accelerate 2D rendering and surprise, 32MB of DDR2 DRAM, on 28 select parts. Target is clearly user interfaces and will fight against low end application processors. Prices range roughly from $10 to $15 at 5k volume.
29 DSPIC33EP and FJ left our world this month, together with 18 PIC24 and 3 PIC32MX.
The nRF52810 is a smaller memory version of the nRF52832 with only 192kB/24kB of Flash/RAM, no 4 dBm boost and fewer peripherals.
No Change this month apart from the removal of the NUC123ZC2AN1.
7 MKV parts got their P suffixes i.e. the KMS-PMSM and BLDC software stacks. Buddling software with semiconductor has been a growing trend, allowing semi-conductor companies to provide more value to their customers.
No significant changes this month at Renesas RX and RL78.
Well, ain’t no more the summer at SLAB this month with 4 new parts in the Blue Gecko family (EFR32BG13), a 512 kB Flash version with a -30 to 19 dBm output compared to 1,024 kB/-30 to 0 dBm for the EFR32BG12. Same treatment for the Flex Gecko and Mighty Gecko, respectively serving the proprietary and ZigBee protocols. With very similar specs they are likely to be using the same die but different software and factory settings.
No news for the EFM32 and EFM8.
The S6E1B is now completely gone from the portfolio. It was a 40MHz Cortex-M0+ with 24 parts in the FM0 family. RIP.
STMicroelectronics removed the STM32H753 in the higher temperature grade from the site. On the other side, higher temperature parts are appearing for the F302, F412, F746, and L486. STM8 was quiet.
Texas Instruments added 8 FRAM parts while removing entirely the MSP430A.
An eclectic mix

There was an eclectic mix of incremental changes at Microchip/Atmel, Nuvoton, NXP, Renesas, STMicroelectronics and Texas Instruments with new Cortex-M7s and more low power MCUs. Is Microchip starting a slow realignment of its portfolio with DSPIC33 declining in favor of the PIC32? Microchip announced the PIC32MK: another sign that Cortex-M and proprietary architectures are here to stay side by side?
A few parts made it out this month in the AT Tiny family, the ATTiny1614 and 1616 bring new (smaller) package options to the existing ATTiny1617.
The ATMega gave up 10 part numbers mostly tape and reel versions.
On the Cortex-M front, the activity was concentrated on the ATSAME70 and S70, the powerful Cortex-M7 based families. The new parts add LQFP64 and BGA144 packages to the existing portfolio. 38 parts came out in total.
No change.
XMC4400F100F512ABXUMA1 migrated to XMC4400F100F512ABXQMA1.
The parts list for Microchip added 138 new MCUs, and took away only 64. All of the action took place with the PIC32MK and PIC32MX.
In particular, Microchip announced the PIC32MK earlier this month. The PIC32MK family targets precision dual Motor Control applications (PIC32MK MC) and General Purpose (PIC32MK GP) applications. All MC and GP devices feature a 120 MHz 32-bit core that supports DSP instructions. The devices come with up to 1MB Flash, 4 KB of EEPROM and 256kB SRAM.
Microchip also added parts to the existing PIC32MX, the PIC32MX154/174 and PIC32MX254/274, a 72MHz MIPS core packed with 128/256 kB of Flash.
The bleeding happened at the DSPIC33EP256/512 as well as the PIC24EP128/256/512.
No change this month.
10 products saw the light of the day this month. The 72 MHz Cortex-M0 NUC126 sports a crystal-less USB 2.0 FS interface, adjustable VDDIO pins (1.8V to 5.5V). Temperature ranges from -40℃ to 105℃, up to 256/20 kB of Flash/RAM with 48-, 64- or 100-pin packages. Its cousin, the M0564 is similar, but lacks the USB port.
The LPC546xx MCU family got 6 new parts (LPC54606xxx). The 180 MHz Cortex-M4 core is surrounded by USB+PHY, Ethernet and CAN interfaces and packaged in TFBGA or LQFP with 256 or 512 kB of Flash.
Renesas added a few parts to the RX24T, a group focused on dual inverter control with a built-in FPU. It supports 2.7 V to 5.5 V, and is pin-compatible with the RX62T Group.
It’s already the summer at SLAB: no change recorded in the portfolio.
A few parts were added in the PSoC4 family, but we could not find proper documentation. These are Z or ZT-suffix of existing parts.
STMicroelectronics increased its ARM Cortex-based STM32’s by 53 of which, 16 were mere package or temperature variations of existing parts.
The real news is the STM32L451/2 and STM32L462 families that add to the 141-strong STM32L4 series. The STM32L451/2xx devices embeds a Quad SPI, a 12-bit ADC, two comparators, one operational amplifier, one DAC channel. The L451 lacks the USB found on the L452.
Texas Instruments added over 33 new 16-bit low-power MSP430 to their listings.
The bulk of the new comers is found in the MSP430F2131 and MSP430F2132, beefed up versions (8-16 kB Flash) of the existing MSP430F210x/1x.
