【NUCLEO-L496ZG评测】开箱上电+特性介绍

何昌昕

首先非常感谢社区举办的这个福利活动 也是第一次参加，非常幸运能够以9.9拿到这么精致的板子。板子前两天就收到了，这两天事情比较多，今天得空出来简单评测一下。废话不多说，开箱上照， 包装简单精致，白色的板卡高端大气，自带ST-LINK调试器，免去了外接下载器，一根数据线搞定，黑色母座兼容arudino接口，背部引出的针脚方便外接杜邦线，非常实用，三个用户指示灯，一个用户按键，简单实用，整体设计非常喜欢。直接上电 就算原价购买性价比也是很高，STM32整个系列的板子做得都很棒，非常适合用来学习。
引脚分布：比丝印上更清楚 直接明了

摘抄了一段芯片特性：
            STM32L496ZGT6                                                                                            
                        The STM32L496xx devices are the ultra-low-power microcontrollers based on the high-performance ARM® Cortex®-M4 32-bit RISC core operating at a frequency of up to 80 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all ARM single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.
The STM32L496xx devices embed high-speed memories (up to 1 Mbyte of Flash memory, 320 Kbyte of SRAM), a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), a Quad SPI flash memories interface (available on all packages) and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.
The STM32L496xx devices embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, proprietary code readout protection and Firewall.
The devices offer up to three fast 12-bit ADCs (5 Msps), two comparators, two operational amplifiers, two DAC channels, an internal voltage reference buffer, a low-power RTC, two general-purpose 32-bit timer, two 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and two 16-bit low-power timers. The devices support four digital filters for external sigma delta modulators (DFSDM).
In addition, up to 24 capacitive sensing channels are available. The devices also embed an integrated LCD driver 8x40 or 4x44, with internal step-up converter.
They also feature standard and advanced communication interfaces.
