STMicroelectronics STM8L152C8T6

Overview

STM8L152C8T6 from STMicroelectronics is an 8-bit ultra-low-power microcontroller featuring 64 KB Flash, 2 KB data EEPROM, RTC, LCD controller, 12-bit ADC (1 Msps, 28 channels), dual 12-bit DACs, and three USARTs. It operates from 1.65–3.6 V across –40 to +85 °C and targets battery-powered metering, portable medical devices, and smart sensors requiring sub-µA sleep current.

For engineers reviewing the STM8L152C8T6 datasheet, STM8L152C8T6 pinout, STM8L152C8T6 application, or STM8L152C8T6 equivalent, key selection criteria include active-halt mode current (1.4 µA with full RTC), LCD drive capability (8×40/4×44), capacitive touch support (16 channels), and SWIM-based non-intrusive debugging.

Technical Context

The STM8L152C8T6 implements a Harvard-architecture STM8 core with 3-stage pipeline, delivering 16 CISC MIPS at 16 MHz. Its clock system integrates dual crystal oscillators (32 kHz LSE, 1–16 MHz HSE), factory-trimmed 16 MHz RC, and clock security for fail-safe operation.

Power management includes five low-power modes-Halt (400 nA), Active-halt (1.4 µA with RTC), Low-power wait (3 µA), and fast wake-up (4.7 µs)-enabled by programmable BOR thresholds, PVD, and per-pin leakage control (50 nA/I/O).

FAQ

What is the maximum operating frequency and corresponding power consumption of the STM8L152C8T6?

The STM8L152C8T6 runs at up to 16 MHz with a typical active current of 200 µA/MHz plus 330 µA base consumption. At 16 MHz and 3.0 V, total current is approximately 3.53 mA, verified in DS6948 Rev 11 Table 20. This balance enables responsive real-time control while preserving battery life in duty-cycled systems.

Does the STM8L152C8T6 support hardware-accelerated capacitive touch sensing?

Yes-it integrates a dedicated hardware touch sensing controller supporting up to 16 channels with built-in noise filtering, auto-calibration, and low-power acquisition modes. It supports touchkey, proximity, linear slider, and rotary wheel configurations without CPU intervention, as confirmed in Section 3.13 of DS6948 Rev 11.

Can the STM8L152C8T6 drive a segmented LCD directly without external components?

Yes-the device includes a fully integrated LCD controller with internal step-up converter generating VLCD (2.3–4.2 V). It drives up to 8×40 or 4×44 segments directly using internal bias voltages, eliminating need for external charge pumps or resistor networks per DS6948 Rev 11 Section 3.6 and Table 45.

What debug interface does the STM8L152C8T6 use, and is JTAG supported?

The STM8L152C8T6 uses the Single-Wire Interface Module (SWIM) for programming and non-intrusive debugging via a dedicated SWIM pin. JTAG is not supported; SWIM provides full flash read/write, breakpoint, and register access with minimal pin count and zero impact on application I/O resources.
