Product details

32 MHz Cortex-M3 with 64 KB flash — sensor-node sweet spot

The STM32L152C8T6A: A dedicated 4 KB EEPROM block holds calibration coefficients or configuration parameters that survive a full chip erase, so field firmware updates don't wipe the production trim data.

Analog front-end and peripheral set for battery-powered acquisition

An integrated LCD driver (up to 8×40 segments) and capacitive sensing controller mean a single-chip UI for a battery-powered panel — the MCU drives the display segments and reads touch inputs directly, saving a separate touch controller and display driver IC. Serial connectivity includes USB (device), I2C, SPI, UART/USART, IrDA, and LINbus — enough for a sensor hub aggregating data from multiple digital peripherals over a shared I2C bus or logging to an SD card over SPI.

48-LQFP (7×7 mm) — hand-solderable, no hidden thermal pad

Surface-mount mounting with 37 general-purpose I/O pins gives enough GPIO for a parallel LCD data bus, a keypad matrix, and several sensor interrupts without multiplexing.

Active lifecycle — no last-time-buy pressure

RoHS3 compliant — no lead, mercury, cadmium, or phthalates above the threshold; the part ships in a tray suitable for pick-and-place or manual assembly.

Frequently asked questions

What is the closest functional second-source to STM32L152C8T6A?

The STM32L151CBU6A is a pin-compatible peer within the same STM32L1 series — same ARM Cortex-M3 core at 32 MHz, same 64 KB flash, same 37 I/O, same analog peripherals (16×12-bit ADC, 2×12-bit DAC). The key difference is the package: the L152C8T6A comes in a 48-LQFP (7×7 mm), while the L151CBU6A is in a 48-UFBGA (5×5 mm) ball-grid array. The LQFP is hand-solderable; the UFBGA requires a reflow oven and X-ray inspection. The L152 variant adds the LCD driver and capacitive sensing controller — if your design uses those peripherals, the L151 will not drop in without firmware changes.
