The additions has increased the number of STM32 MCUs to 60, which all combine the advanced ARM Cortex-M3 core with pin and software compatibility across all variants for efficient product development and shorter design cycles.
The 16 Kbyte memory densities in the access and performance lines are intended for cost-sensitive applications with high code density. QFN36, LQFP48 and LQFP64 packages are all supported at 16 Kbytes. With this latest expansion, both families now deliver flash densities from 16 Kbytes to 512 Kbytes, with up to 48 Kbytes of SRAM in the access line and 64 Kbytes of SRAM in the performance line.
To support miniaturization and cost saving, this broad spectrum of memory densities combines with high integration of advanced peripherals, including embedded USART operating at up to 4.5 Mbit/s, 18MHz SPI master and slave interfaces, PWM timer with 72MHz input, up to 48MHz SDIO, and an I²S module supporting sampling up to 48kHz.
The 48-MHz USB access line of MCUs, in densities from 16 Kbytes to 128 Kbytes, integrates a USB Full-Speed Device peripheral in a competitively priced, low-power family. With LQFP64 and LQFP48 package configurations, there are eight devices available. To accelerate design and development, the supporting STM32 USB developer kit provides a complete, USB-certified firmware package including support for control-transfer, interrupt-transfer, bulk-transfer and isochronous-transfer modes as well as device firmware updates and virtual COM operation.
Pricing: For orders of 10,000 pieces, the USB access line MCUs are priced at $1.86 in the 16-Kbyte LQFP48 configuration and $2.97 for 128 Kbyte devices in LQFP64. STM32 prices now start at $1.68 for 16-Kbyte QFN36 access line devices, also in quantities of 10,000 pieces.
