ATSAM4SD32C中文资料SAM 32-bit MCU数据手册Microchip规格书

描述 Description

For New Designs, we highly recommend to consider Revision B for Prototypes and Production.Microchip's ARM-based SAM4SD32 microcontroller builds on the high-performance 32-bit Cortex®-M4 core. The SAM4SD32 features: 2MB of flash memory and 160KB of SRAM 2KB of integrated cache memory Maximum operating speed of 120MHz Dual-bank Flash Best-in-class power consumption: 200uA/MHz in active mode, down to 1uA at 1.8V in back-up mode with the RTC running 1.62V to 3.6V power supply Extensive peripheral set for connectivity, system control and analog interfacing Pin-to-pin compatible with Microchip SAM7S, SAM3N and SAM3S MCUs Supported by Atmel Studio, Software Framework(ASF) and the SAM4S-EK2
