Product details
Overview
STM8L152C8U6 from STMicroelectronics is an 8-bit ultra-low-power microcontroller featuring 64 KB Flash, 2 KB data EEPROM, RTC, LCD controller (8×40/4×44), dual 12-bit DACs, 12-bit ADC (1 Msps, 28 channels), two USARTs, I²C, SPI, and up to 48 GPIOs - deployed in battery-powered industrial sensors and portable medical devices.
For engineers reviewing the STM8L152C8U6 datasheet, STM8L152C8U6 pinout, STM8L152C8U6 application, or STM8L152C8U6 equivalent, key selection criteria include ultra-low-power operation (400 nA Halt mode), integrated LCD driver with step-up converter, dual DAC output buffering, RTC digital calibration (±0.5 ppm), and capacitive touch sensing support for human-interface designs.
Technical Context
The STM8L152C8U6 implements a Harvard-architecture STM8 core with 3-stage pipeline, delivering 16 CISC MIPS at 16 MHz. It integrates a clock security system, three crystal oscillator options (32 kHz LSE, 1–16 MHz HSE, and factory-trimmed 16 MHz/38 kHz RC), and independent BOR with five programmable thresholds.
Its analog subsystem includes two ultra-low-power comparators (one rail-to-rail, one with fixed threshold), a temperature sensor, internal reference voltage, and dual 12-bit DACs supporting simultaneous buffered outputs on PB4–PB6 - all operating down to 1.65 V supply without BOR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | Harvard, 3-stage pipeline STM8 CPU; enables deterministic interrupt latency and efficient code density for resource-constrained firmware. |
| Max Operating Frequency | 16 MHz; delivers 16 CISC MIPS peak performance while maintaining sub-200 µA/MHz active power consumption. |
| Flash / EEPROM | 64 KB Flash with RWW and ECC; 2 KB data EEPROM with error correction - supports robust field firmware updates and parameter storage. |
| Low-Power Modes | Halt (400 nA), Active-halt with RTC (1.4 µA), Low-power wait (3 µA); enables multi-year battery life in always-on sensing nodes. |
| ADC / DAC | 12-bit ADC, 1 Msps, 28 channels + internal temp sensor/Vref; dual 12-bit DACs with output buffers - suitable for closed-loop analog control and waveform generation. |

FAQ
Does STM8L152C8U6 support in-application programming (IAP) of Flash memory?
Yes. The device supports read-while-write (RWW) Flash operation, enabling firmware updates without halting application execution. IAP is implemented via the built-in bootloader accessed over USART or through user firmware using the Flash programming interface with proper option byte configuration and write-protection disable sequence.
What is the maximum allowed crystal load capacitance for the 32 kHz LSE oscillator?
The LSE oscillator supports external 32.768 kHz crystals with load capacitance of 6 pF to 12.5 pF, as specified in Section 9.3.2 of DS6948 Rev 11. Using a 12.5 pF crystal with matching PCB trace capacitance ensures reliable startup and ±20 ppm frequency stability across -40°C to +85°C.
Can the STM8L152C8U6 drive a 4×44 segment LCD without external components?
Yes. The integrated LCD controller includes a programmable step-up converter that generates the required bias voltage from the main VDD supply (1.65–3.6 V), eliminating need for external charge pumps or voltage doublers - confirmed in Section 3.6 and Table 45 of the datasheet.
Is SWIM debugging supported in all low-power modes?
No. SWIM debugging remains active only in Run, Wait, and Low-power run modes. It is disabled in Low-power wait, Active-halt, and Halt modes to preserve ultra-low current - requiring wake-up via interrupt or reset before resuming debug session, as detailed in Section 3.19 and Table 26.
