Product Overview
The STM8L152M8T6 is the only STM8 MCU that combines ultra-low-power operation with an integrated LCD segment driver — a unique combination that eliminates the need for external LCD controller ICs (e.g., HT1621, PCF8576). The LCD controller can drive up to 192 segments in 8-COM mode — sufficient for a 6-digit 7-segment display with icons, a 4×20 character alphanumeric display, or a custom segmented instrument panel showing battery voltage, current, flight time, GPS coordinates, and status indicators.
For drone applications, this MCU enables battery-powered handheld telemetry displays that consume only 3 µA in display-ON sleep mode (LCD showing static data, CPU in Halt, RTC running). A CR2032 coin cell can power such a display for months of continuous operation. The dual 12-bit DACs can generate analog output signals for legacy equipment, and the triple USARTs support simultaneous GPS, telemetry radio, and debug console connections.
Key Features & Benefits
Integrated LCD Driver (Up to 192 Segments) — No External LCD Controller
The on-chip LCD controller with programmable bias (1/2, 1/3, 1/4), duty cycle (static to 1/8), and contrast adjustment drives segment LCDs directly — no external driver IC or charge pump needed. Supports up to 4 COM × 28 SEG or 8 COM × 24 SEG configurations. LCD waveforms are generated autonomously with zero CPU overhead during display refresh.
Ultra-Low-Power LCD Operation — 3 µA with Live Display
With the LCD controller running (displaying static data), the CPU in Halt, and the RTC keeping time, total current consumption is approximately 3 µA — enabling a CR2450 coin cell to power a continuously-on display for over 2 years. The LCD can be updated from DMA-driven ADC data without waking the CPU.
Dual 12-Bit DACs + 25-Channel ADC — Rich Analog I/O
Two independent 12-bit DAC outputs (unique among STM8L devices — the L151 has only one) enable simultaneous generation of analog reference and control signals. The 25-channel ADC with DMA-driven scanning provides comprehensive analog input capability.
Target Applications
Drone Ground-Station Telemetry Display
A handheld, battery-powered instrument displaying real-time drone telemetry: GPS coordinates, altitude, speed, battery voltage/current, RSSI, and flight mode — all on a direct-drive custom segment LCD. The 3× USARTs connect to GPS module, telemetry radio (915/433 MHz), and USB-serial for configuration. Runs for months on AA batteries.
Drone Smart Battery Display Module
An LCD-equipped battery management module that displays per-cell voltages, pack SOC%, cycle count, and health status directly on the battery — no smartphone app or FC connection needed. The LCD shows critical data even when the drone is powered off, consuming only 3 µA.
Portable Drone Diagnostics and Configuration Tool
A pocket-sized tool for field-configuring ESCs, checking motor health, and displaying sensor data — featuring a large segmented LCD driven by the STM8L152's LCD controller. Communicates via USART with BLHeli_S passthrough, I²C sensors, and SPI memory.
Frequently Asked Questions
What types of LCDs can the STM8L152 drive directly?
The LCD controller drives passive segment (non-matrix) LCDs: 7-segment numeric displays, 14-segment alphanumeric displays, custom icon/symbol panels, and bar-graph displays. It does NOT drive graphical/TFT LCDs (those require a framebuffer and parallel RGB interface, available only on STM32F4+ MCUs). For drone OSD with graphical overlay, use an STM32F429 with LTDC — not the STM8L152.
Does the LCD driver work in all low-power modes?
Yes. The LCD controller has its own clock source (LSI or LSE) and continues refreshing the display independently in Halt, Active-Halt, and Wait modes. The CPU can be completely stopped while the LCD shows static or slowly-updating data — only waking periodically to update displayed values from new sensor readings.
