A busy summer
In the heat of the summer, new families are being launched, who would have known? ST created the STM32F7x0 and STM32H7x0 with minimal amounts of Flash memory and the result is… a Cortex-M7 part for $1.64@1ku. NXP showed the MKW35/36, a BT5 Cortex-M0+ MCU focused on the automotive market while the new Cypress PSoC 4700 family chases the UI market with advanced sensing coupled with a Cortex-M0+ MCU, what a summer.
There were minor adds to the ATTiny portfolio
On the Cortex-M front, Microchip added a few package variants to the SAML10 with the 24-pin SAML10D.
Microchip added over 80 variants to the dsPIC33CH announced last month. It is a dual-core built for motor control and industrial applications.
Nordic launched the nRF51822, with BT5 and proprietary stacks on a Cortex-M0 dressed in 48-QFN and WLCSP packages.
NXP just launched the KW35/36, a BT5/Generic FSK connectivity for the automotive market. The KW35/36 integrates a Cortex-M0+, up to 512/64 kB Flash/RAM. The Kinetis KW35/36A feature AEC Q100-Grade 2 temperature range qualification.
No significant change.
There were a few EFR32BG parts (Bluetooth) adding a new QFN68 package combination.
Cypress launches the PSoC 4700 Family with advanced sensing. This family includes the PSoC 4700 S-Series with a 48 MHz Cortex-M0+, 32/4 kB Flash/RAM, 1x 10-bit ADC, 2x comparators, 2x 7-bit IDACs, an inductive sensing block that enables sensing of metal objects, a CapSense block with self- and mutual-capacitance sensing, 2x multiplexed I2C, SPI or UART. It comes in WLCSP25, QFN24 or TQFP48.
ST just launched the Cortex-M7 based STM32F7x0 and H7x0 Value Lines and emphasizes low cost, upward compatibility with larger Flash/RAM sized members of the F7/H7 family. It is interesting to note these parts are not flashless but nevertheless hit a similar market than NXP’s i.MXRT.
The 216 MHz STM32F730 keeps cryptographic hardware acceleration, a USB2 HS with PHY, and a CAN interface. On the memory side, 64 kB Flash with 8 kB I/D caches and 256 kB RAM and 16kB+64KB of TCM for the most critical routines and data.
The STM32F750 adds a TFT-LCD and graphics acceleration, 2x CAN, Ethernet, camera interface, and 2x USB2 with FS PHY. There are 64Kbytes of Flash, 4Kbyte instruction and 4Kbyte data caches, 320KB of system RAM, and 16kB+64KB TCM.
Finally, the 400 MHz STM32H750 adds a hardware JPEG coder/decoder a CANFD port, 16-bit ADCs with 128 kB Flash, 16 kB I/D caches, 864 kB RAM and the 64kB+128KB of TCM.
The STM32F730, STM32F750, and STM32H750 Value Line MCUs are in production, with LQFP and BGA package options from 64-pin to 240-pin. Prices start from $1.64 for the STM32F730, $2.39 for the STM32F750 and $2.69 for the STM32H750 for 1ku.
No significant change.
