80 MHz Cortex-M4 with 1 MB Flash — what it means for the BOM
The STMicroelectronics STM32L4A6ZGT6P is a 32-bit ARM Cortex-M4 MCU running at 80 MHz, with 1 MB of Flash program memory and 320 KB of SRAM. It carries 115 I/O lines, a full set of.
115 I/O and peripheral set — integration note
The 115 I/O count in a 144-LQFP package gives you enough pins for a parallel LCD interface, external memory bus (EBI/EMI), and a CANbus transceiver without multiplexing. The QSPI interface supports external Flash or RAM for data logging or display buffers. Brown-out detect and reset are on-chip, so the external supervisor can be a simple RC pair.
Lifecycle and sourcing
This part carries an active lifecycle status. It is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. No second source or successor is listed in the official record, so the BOM should plan for single-sourced supply.
