The 1 MB Flash is organized as 1M x 8 bits, and the 320 KB SRAM as 320K x 8 bits. This memory configuration supports dual-bank OTA updates or large display buffers when driving the integrated LCD controller. ## Connectivity and peripheral set — USB OTG, CAN, and multiple serial buses The EBI/EMI bus allows glueless connection to external parallel memory or FPGAs. For analog sensing, there are 16 channels of 12-bit ADC and two 12-bit DAC channels. The USB OTG peripheral supports host and device modes, making this part a candidate for USB-based data loggers or industrial HMI panels that connect to a keyboard or thumb drive. ## Package and footprint — 48-LQFP (7x7 mm) Housed in a 48-LQFP package with a 7x7 mm body, the STM32L4Q5CGT6 is a surface-mount device. The 48-pin LQFP footprint is common across the STM32L4 value-line, easing layout reuse if migrating between density options.","metaTitle":"STM32L4Q5CGT6 ARM Cortex-M4 MCU, 120 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32L4Q5CGT6 32-bit ARM Cortex-M4 MCU at 120 MHz with 1 MB Flash and 320 KB SRAM in 48-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"120MHz","Series":"STM32L4","Package":"Tray","RAM Size":"320K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, IrDA, LINbus, MMC/SD, SAI, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L4Q5","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.4600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/91f0a99a5f640d070677a4605b457dc4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32L4Q5CGT6?","answer":"The core processor runs at 120 MHz."},{"question":"What is the closest pin-compatible alternative to STM32L4Q5CGT6?","answer":"Pin-compatible alternatives exist within the STM32L4 series in the 48-LQFP package, such as the STM32L4R5 variant.
