STMicroelectronics Expands STM32 Options with Lower Flash-Density Devices

Hi all,

STMicroelectronics has further extended options for users of its STM32 MCUs, by introducing new devices with 16 Kbyte Flash density as well as a complete new 48MHz series of microcontrollers optimized for USB applications. There are now 60 STM32 MCUs available, combining 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 now added to the 36MHz Access Line and 72MHz Performance Line MCUs are ideal 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 new USB Access Line MCUs, in densities from 16 Kbytes to 128 Kbytes, integrate 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. Development support for all STM32 devices, including the new configurations, comprises evaluation boards and free software libraries from ST, as well as third-party tool chains from vendors including Keil, Hitex, IAR and Raisonance.

Good news on expanding the line. There is one thing I can't determine from the datasheet. I know the AHB clock max is 48MHz, but it's not clear if PLLCLK and SYSCLK max is 48MHz or remaining at 72MHz as in the '103 parts.

This info is important since I generate other clocks for other chips and need to keep other integer multiples for cheap PLL chips. Thanks!

Certainly hope that the new - 16KB parts have a ''normal/customary'' price reduction when compared to middle-density. We will buy immediately should this be the case... Are you looking for something different then what is quoted in the press release? ''STM32 prices now start at $1.68 for 16-Kbyte QFN36 Access Line devices, also in quantities of 10,000 pieces.''

STOne-32-

Mark5's question is a good one. I'm business owner/engineer and it would be immensely helpful if you could use your high office to ''speed'' price info for these new STM's to the field. We have hi-volume products still built with 8 bit uCs - would love to switch to ST - but need price-down from ''middle density.'' Lastly - (know this is ''not'' your doing) clients/I were bitterly disappointed when ''mid density'' 36 pin pricing was announced. The roll-off in pricing did ''not'' follow classic ''pin-starved'' price reductions! As a result ALL of my clients would ''not even consider'' our use of your 36 pin parts. Certainly hope that the new - 16KB parts have a ''normal/customary'' price reduction when compared to middle-density. We will buy immediately should this be the case...

@obtronix-

Thank you. Press release prices can't always be entered on a P.O. Further - the QFN36 singular mention causes concern. (see my post)
