The ARM Cortex-M4 core with FPU operates at up to 80 MHz with 100 DMIPS performance. The device integrates the full STM32L476 peripheral set including three 12-bit ADCs at 5 Msps, two 12-bit DACs, two operational amplifiers with PGA, two ultra-low-power comparators, USB OTG Full-Speed, LCD controller, DFSDM, and 18 communication interfaces. The FlexPowerControl architecture enables ultra-low-power modes down to 30 nA in Shutdown. The 1 MB Flash supports large application code bases with over-the-air firmware update capability enabled by the dual-bank read-while-write architecture.","working_principle":"The STM32L476JGY6TR shares the same core architecture as the STM32L476RET6, with the ARM Cortex-M4 core with FPU and ART Accelerator for zero-wait-state Flash execution at 80 MHz. The 1 MB Flash is organized as two 512 KB banks supporting concurrent read from one bank while erasing or programming the other bank, enabling firmware updates without interrupting application execution. The UFBGA-72 package provides 72 pins in a 4.5 x 4.5 mm footprint with 0.5 mm ball pitch, offering maximum I\/O density for space-constrained designs. The ball map provides access to GPIO ports A through E with full alternate function mapping for all peripherals.","pin_description":"<table><tr><th>Pin Group<\/th><th>Count<\/th><th>Function<\/th><\/tr><tr><td>VDD\/VDDA\/VBAT\/VSS<\/td><td>12<\/td><td>Power supply and ground (digital, analog, backup)<\/td><\/tr><tr><td>PORTA- PORTE<\/td><td>51<\/td><td>GPIO with alternate functions (ADC, DAC, TIM, USART, SPI, I2C, USB, CAN, LCD, SAI, DFSDM, OPAMP, COMP)<\/td><\/tr><tr><td>NRST<\/td><td>1<\/td><td>Reset input<\/td><\/tr><tr><td>BOOT0<\/td><td>1<\/td><td>Boot mode selection<\/td><\/tr><tr><td>OSC<\/td><td>4<\/td><td>HSE and LSE oscillator connections<\/td><\/tr><tr><td>Other<\/td><td>3<\/td><td>Ball configuration and reserved<\/td><\/tr><\/table>","application_scenarios":"<ul><li><strong>Wearable Health Devices<\/strong>: Multi-sensor health monitors with large firmware for BLE stack, DSP algorithms, and over-the-air updates<\/li><li><strong>Smart Metering<\/strong>: Multi-protocol utility meters requiring 1 MB Flash for protocol stacks, data logging, and encryption<\/li><li><strong>Portable Medical<\/strong>: Battery-powered diagnostic devices with LCD interface and USB data transfer<\/li><li><strong>Industrial IoT Gateway<\/strong>: Wireless sensor hub with Sub-GHz or BLE radio, DFSDM precision measurement, and CAN bus<\/li><li><strong>Consumer Wearables<\/strong>: Smartwatch and fitness tracker with LCD, touch sensing, and multi-sensor fusion<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Flash<\/th><th>RAM<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>STM32L476RET6<\/td><td>ST<\/td><td>512 KB<\/td><td>128 KB<\/td><td>LQFP-64<\/td><td>Half Flash, larger package<\/td><\/tr><tr><td>STM32L486JGY6TR<\/td><td>ST<\/td><td>1 MB<\/td><td>128 KB<\/td><td>UFBGA-72<\/td><td>AES-256 hardware crypto<\/td><\/tr><tr><td>STM32L4R9ZIJ6<\/td><td>ST<\/td><td>2 MB<\/td><td>640 KB<\/td><td>BGA-144<\/td><td>STM32L4+, much more Flash\/RAM<\/td><\/tr><tr><td>nRF52840<\/td><td>Nordic<\/td><td>1 MB<\/td><td>256 KB<\/td><td>QFN-73<\/td><td>BLE SoC with integrated radio<\/td><\/tr><tr><td>SAMR34J18B<\/td><td>Microchip<\/td><td>256 KB<\/td><td>40 KB<\/td><td>QFN-48<\/td><td>Sub-GHz LoRa + Cortex-M0+<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/8384","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=8384"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/8384\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=8384"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=8384"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=8384"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=8384"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
