Microchips ARM®-based SAM3U4E is a member of the SAM3U family of flash microcontrollers based on the high-performance 32-bit ARM Cortex®-M3 RISC processor. It operates at a maximum speed of 96MHz and features two 128KB of dual-bank flash memory and 52KB of SRAM. The peripheral set includes a High Speed USB device and PHY at 480Mbps, high-speed multimedia card interface for SDIO/SD/MMC, a 16-bit external bus interface supporting NAND flash, three USARTs, two TWIs (I2C), four SPIs, I2S, four PWM timers, three 16-bit timers, RTC, and eight 12-bit and eight 10-bit ADCs. The architecture sustains high-speed data transfers, with multi-layer bus matrix, multiple SRAM banks, PDC, and DMA support parallel tasks to maximize data throughput. The SAM3U4C operates from 1.62V to 3.6V and is available in 144-pin LQFP and BGA packages.Microcontroller Features Core ARM7TDMI® ARM® Thumb® Processor 32-bit RISC Architecture High-density 16-bit Instruction Set EmbeddedICE™ In-circuit Emulation More information: ![](/p.gif) | ![](/p.gif) | Family Name: | ATSAM | Package Type: | LQFP | Mounting Type: | Surface Mount | Pin Count: | 144 | Device Core: | ARM Cortex M3 | Data Bus Width: | 32bit | Program Memory Size: | 256 kB | Maximum Frequency: | 96MHz | RAM Size: | 52 kB | USB Channels: | 1 | Number of PWM Units: | 1 x 16 bit | Number of SPI Channels: | 5 | Number of CAN Channels: | 0 | Number of I2C Channels: | 2 | Number of UART Channels: | 1 |
