STM32L151C8T6A

STM32L151C8T6A is the tray LQFP-48 ordering code for the STMicroelectronics STM32L151 ultra-low-power microcontroller in the -A family step, listed as Active on the maker’s eStore page for this exact code. The code decodes as C for the 48-pin package and 8 for 64 KB of Flash memory. Verified figures for this code: an Arm Cortex-M3 core at 32 MHz, 64 KB of Flash and USB connectivity, on a supply of 1.65 V to 3.6 V, over −40 °C to +85 °C, industrial grade, Ecopack2. One family fact decides whole designs: no STM32L151 device carries the segment LCD controller, in either the standard or the -A step - ST’s own family text reserves that peripheral to the STM32L152 line and excepts the L151 devices from it by name - so a design driving a segment display directly from the MCU belongs on an L152 code, not on any L151. Selection advice: read the family digits, not just the suffix, before approving any STM32L151 substitution; the Flash size, the package and the core can all match a candidate replacement while the peripheral set does not, and a parameter table sorted by memory size will not show you the difference. Parameters verified against the ST eStore listing for this exact code and the STM32L151 family documentation (DS7769).
