At this frequency the Flash requires zero wait states for most accesses, so interrupt latency stays deterministic — important for real-time sensor polling or PWM update loops. If your application needs to toggle I/O or service a UART at higher rates, the internal oscillator and PLL let you scale the clock down to a few hundred kHz to save dynamic current; the 32 MHz figure is the headroom you have when you need it, not the operating point you must run at. ## 192 KB Flash + 20 KB RAM + 6 KB EEPROM — memory fit for a single-chip node The 20 KB RAM supports a few large buffers or a modest heap. The 6 KB EEPROM stores calibration data without an external chip. With 51 I/Os in the 64-LQFP package, the STM32L071RZT6TR can drive a small TFT display parallel bus, read a dozen digital sensors, and still leave pins for a UART debug port. DMA offloads the CPU for data transfers between peripherals and memory, and the PWM timers can generate motor drive or LED dimming signals directly. The brown-out detect and POR eliminate external supervisor ICs for low-cost designs. For a procurement decision, this removes the supply-chain risk of an imminent obsolescence-driven redesign. This listing sources the STM32L071RZT6TR through independent distribution channels. Availability and current market pricing are confirmed at the time of RFQ — the part is not on allocation or restricted to authorized-distributor-only channels, so we can quote it against a BOM line for both prototype quantities and production volumes.","metaTitle":"STM32L071RZT6TR ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STMicroelectronics STM32L071RZT6TR 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 192 KB Flash, 20 KB RAM, 6 KB EEPROM.
