ARM Cortex-M3 32-bit microcontroller ICs with new 512KB flash

STMicroelectronics has extended its STM32 L1 series of ultra-low-power ARM Cortex-M3 32-bit microcontrollers with new 512KB flash devices. ST says its L1 series now includes more than 70 part numbers in three lines that offer the market-unique combination of ultra-low power consumption and memory size up to 512KB of Flash and 80KB of RAM. ST employs its proprietary ultra-low-leakage 110nm CMOS process and optimized architecture to design and fabricate these new MCUs targeting cost-efficient embedded designs in connected and battery-operated applications in fitness, healthcare, wearable, and industrial/metering domains.. Key features of the L1 series as per ST include: High-performance ARM Cortex-M3 32-bit core: up to 33 DMIPS operating at 32MHz; Pin-to-pin and software compatibility with all previous STM32 L1 devices; Run-mode dynamic power consumption 257µA/MHz at 32MHz down to 177µA/MHz @ 4MHz Two ultra-low-power modes: down to 435nA with SRAM retention; True embedded EEPROM; Dual-bank flash allowing fast and fail-safe firmware updates and rollback, thanks to the RWW (Read-While-Write) capabilities. ST says the new devices benefit from the STM32 L1 DNA including voltage scaling, flexible clock tree with low-power multi-speed internal (MSI) oscillator, and an operating temperature range of -40 to +85°C or up to 105°C in low-power modes, while ST’s new 110nm pro...
