一、MAX32662GTJ+產品描述

1.MAX32662GTJ+ 產品特性

General DescriptionIn the DARWIN family, the MAX32662 is an ultra-lowpower, cost-effective, highly integrated 32-bitmicrocontroller designed for small battery-powereddevices. It combines a flexible peripheral and feature mixwith the powerful Arm? Cortex?-M4 processor withfloating point unit (FPU) in a small form factor.The MAX32662 enables complex edge-based designswithout compromising battery life, and it also offers legacydesigns an easy and cost optimal upgrade path from 8- or16-bit microcontrollers.Integrating 256KB of flash memory and 80KB of SRAM,the MAX32662 easily accommodates sensor code andcomplex algorithms.Peripherals include SPI, UART, I2C, I2S, CAN 2.0B, anda 12-bit ADC.A ROM-based secure bootloader uses 256-bit ellipticcurve digital signature algorithm (ECDSA-256) encryptionto ensure trusted and authenticated updates of customersoftware.The device is available in a 5mm x 5mm, 32-pin TQFNEP.
