The 1 MB Flash is organized as 1M x 8 bits, suitable for complex firmware stacks including a real-time OS, communication protocol stacks, and application code. The 192 KB SRAM (192K x 8) provides room for large data buffers, double-buffered display frames, or DSP coefficient tables without external memory. ## Analog and connectivity integration The LCD parallel interface supports direct drive of small TFT panels. These peripherals reduce total component count in applications like industrial PLCs, human-machine interfaces, and embedded gateways.","metaTitle":"STM32F405ZGT6J STM32F4 ARM Cortex-M4 MCU, 168 MHz","metaDescription":"STM32F405ZGT6J 32-bit ARM Cortex-M4 MCU at 168 MHz with 1 MB Flash, 192 KB RAM, 114 I/O, 144-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"168MHz","Series":"STM32F4","Package":"Tray","RAM Size":"192K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, IrDA, LINbus, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"114","Core Processor":"ARM® Cortex®-M4","Package / Case":"144-LQFP","Product Status":"Obsolete","Data Converters":"A/D 24x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F405","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"144-LQFP (20x20)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.9500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ba3a059be9cfe6bdf7cf0dbd3dcfbee9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F405ZGT6J/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STM32F405ZGT6J?","answer":"STMicroelectronics has not published a single direct successor for the STM32F405ZGT6J. Within the STM32F4 family, the STM32F407ZGT6 is a common pin-compatible alternative that adds a hardware FPU and additional peripherals while maintaining the same 144-LQFP footprint, 1 MB Flash, and 192 KB SRAM configuration. Verify the peripheral set matches your application before substituting."},{"question":"Does STM32F405ZGT6J come in a tray?","answer":"The STM32F405ZGT6J is listed with a Tray shipping medium. The device package is a 144-LQFP (20x20 mm), surface-mount. Tray packaging is typical for LQFP devices in engineering samples and low-to-medium volume production."},{"question":"What is the difference between STM32F405ZGT6J and STM32F407ZGT6?","answer":"Both are 168 MHz ARM Cortex-M4 MCUs in the same 144-LQFP package with 1 MB Flash and 192 KB SRAM. The STM32F407ZGT6 adds a hardware cryptographic accelerator, a true random number generator, and an additional 12-bit DAC channel. The STM32F405ZGT6J omits these crypto/TRNG blocks but is otherwise pin-compatible. If your application does not require hardware encryption, the F405 is functionally equivalent."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F405ZGT6J","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F405ZGT6J when reusing this data.
