STMicroelectronics STM8L152C8T6TR

Overview

STM8L152C8T6TR 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 two ultra-low-power comparators. 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 STM8L152C8T6TR datasheet, STM8L152C8T6TR pinout, STM8L152C8T6TR application, or STM8L152C8T6TR equivalent, key selection criteria include active-halt mode current (1.4 µA), fast wake-up time (4.7 µs), LCD support (8×40), capacitive touch capability (16 channels), and SWIM-based non-intrusive debugging.

Technical Context

The STM8L152C8T6TR 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 system for fail-safe operation.

Power management includes five low-power modes-Halt (400 nA), Active-halt with full RTC (1.4 µA), Low-power wait (3 µA), Low-power run (5.9 µA), and Wait-with programmable BOR thresholds and PVD. The RTC provides BCD calendar, digital calibration (±0.5 ppm), and anti-tamper detection.

FAQ

What is the maximum operating frequency and core architecture of the STM8L152C8T6TR?

The STM8L152C8T6TR features an 8-bit STM8 core with Harvard architecture and 3-stage pipeline, achieving 16 CISC MIPS at its maximum operating frequency of 16 MHz. It uses a single-cycle instruction set and supports up to 40 external interrupt sources with vectorized priority handling.

Does the STM8L152C8T6TR support capacitive touch sensing, and how many channels are available?

Yes, the STM8L152C8T6TR integrates a hardware-accelerated capacitive sensing controller supporting up to 16 channels. It natively implements touchkey, proximity, linear touch, and rotary touch sensing without external components, using dedicated I/O pins and built-in charge-transfer measurement logic.

What LCD configurations does the STM8L152C8T6TR support, and is an external booster required?

The device supports LCD displays up to 8×40 segments or 4×44 segments. It includes an integrated step-up converter that generates VLCD internally, eliminating the need for an external booster IC. Segment and common drive lines are mapped to dedicated pins (e.g., SEG0–SEG39, COM0–COM7) in LQFP48 package.

What debug interface does the STM8L152C8T6TR use, and is JTAG supported?

The STM8L152C8T6TR uses the SWIM (Single-Wire Interface Module) debug interface-requiring only one pin (SWIM) and NRST for non-intrusive programming and real-time debugging. JTAG is not supported; SWIM enables full flash read/write, breakpoint setting, and register inspection at runtime with minimal pin count.
