The ultra-low-power STM32L151x6/8/B and STM32L152x6/8/B devices incorporate the connectivity power of the universal serial bus (USB) with the high-performance ARM®Cortex®-M3 32-bit RISC core operating at 32 MHz frequency (33.3 DMIPS), a memory protection unit (MPU), high-speed embedded memories (Flash memory up to 128 Kbytes and RAM up to 16 Kbytes) and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All the devices offer a 12-bit ADC, 2 DACs and 2 ultra-low-power comparators, six general-purpose 16-bit timers and two basic timers, which can be used as time bases. Moreover, the STM32L151x6/8/B and STM32L152x6/8/B devices contain standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs and a USB. The STM32L151x6/8/B and STM32L152x6/8/B devices offer up to 20 capacitive sensing channels to simply add touch sensing functionality to any application. They also include a real-time clock and a set of backup registers that remain powered in Standby mode. Finally, the integrated LCD controller (except STM32L151x6/8/B devices) has a built-in LCD voltage generator that allows to drive up to 8 multiplexed LCDs with contrast independent of the supply voltage. The ultra-low-power STM32L151x6/8/B and STM32L152x6/8/B devices operate from a 1.8 to 3.6 V power supply (down to 1.65 V at power down) with BOR and from a 1.65 to 3.6 V power supply without BOR option. It is available in the -40 to +85 °C temperature range, extended to 105°C in low power dissipation state. A comprehensive set of power-saving modes allows the design of low-power applications. https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2020-07-23 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2021-04-04 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2021-05-21 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2021-12-05 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2023-04-29 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2023-05-24 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2023-08-01 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2023-10-11 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2024-11-19 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2024-12-16 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2025-03-09 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2025-03-27 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2025-04-24 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2025-07-31 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2025-10-19 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2026-03-08 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2026-03-27 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2026-05-13 https://elecena.pl/product/17079321/stm32l151r8t6-ultra-low-power-arm-cortex-m3-mcu-with-64-kbytes-of-flash-memory-32-mhz-cpu-usb 2026-07-09
