Product details

16 MHz 8-bit core with EnergyLite lean

The STM8L052C6T6 runs the STM8 core at 16 MHz — the ceiling is set by flash wait-states, not the core itself, so tight loops that fit in cache execute at full speed while random flash access adds a cycle. 32 KB of program flash and 2 KB of RAM (2K x 8) give enough room for a single-task control loop or a small scheduler, but the RAM budget is tight for a full RTOS heap.

Analog front-end and peripheral fit

25-channel 12-bit ADC (A/D 25x12b) covers multi-sensor inputs — temperature, pressure, current sense — without an external multiplexer. The peripheral set includes LCD drive, DMA, IrDA, and a watchdog timer (Brown-out Detect/Reset, DMA, IR, LCD, POR, PWM, WDT), which targets battery-powered metering, handheld instruments, and human-interface devices. I²C, SPI, and UART/USART connectivity handles sensor buses and serial displays.

Supply and temperature envelope

Industrial temperature grade (-40°C to +85°C) means it lives in factory-floor enclosures, outdoor metering cabinets, or engine-bay-adjacent electronics where ambient hits 70°C with self-heating margin.

STMicroelectronics lists the STM8L052C6T6 as active. No last-time-buy window, no NRND flag — it is a current-production part available through standard distribution. ROHS3 compliant.

Frequently asked questions

How does the STM8L052C6T6 compare to the STM32L151CBU6A?

The STM32L151CBU6A is a 32-bit ARM Cortex-M3 device running at 32 MHz with 32 KB flash, while the STM8L052C6T6 is an 8-bit STM8 core at 16 MHz. Both come in 48-pin LQFP packages, but the pinouts differ — they are not drop-in replacements. The STM32L151CBU6A adds USB, a second DAC channel, and capacitive sensing, but draws higher active current. Choose the STM8L for simpler, lower-power 8-bit applications; the STM32L for 32-bit throughput and USB connectivity.

What is the STM8L052C6T6's listed speed?

The core runs at 16 MHz. This is the maximum clock from the internal oscillator — no external crystal is required for the core clock, though an external source can be used via the oscillator I/O pins.

What compliance documentation does STMicroelectronics provide for the STM8L052C6T6?

The device is ROHS3 compliant. Standard STMicroelectronics documentation includes the datasheet, reference manual, and application notes. No UL or IEC certification is listed for this part — those are typically system-level, not component-level.
