SAM3U Series

SAM3U Description
Atmel's SAM3U series is a member of a family of Flash microcontrollers based on the high per-
formance 32-bit ARM Cortex-M3 RISC processor. It operates at a maximum speed of 96 MHz
and features up to 256 Kbytes of Flash and up to 52 Kbytes of SRAM. The peripheral set
includes a High Speed USB Device port with embedded transceiver, a High Speed MCI for
SDIO/SD/MMC, an External Bus Interface with NAND Flash controller, up to 4xUSARTs
(SAM3U1C/2C/4C have 3), up to 2xTWIs (SAM3U1C/2C/4C have 1), up to 5xSPIs
SAM3U1C/2C/4C have 4), as well as 4xPWM timers, 3xgeneral purpose 16-bit timers, an RTC,
a 12-bit ADC and a 10-bit ADC.
The SAM3U architecture is specifically designed to sustain high speed data transfers. It includes
a multi-layer bus matrix as well as multiple SRAM banks, PDC and DMA channels that enable it
to run tasks in parallel and maximize data throughput.
It can operate from 1.62V to 3.6V and comes in 100-pin and 144-pin LQFP and BGA packages.
The SAM3U device is particularly well suited for USB applications: data loggers, PC peripherals
and any high speed bridge (USB to SDIO, USB to SPI, USB to External Bus Interface).
1.1
Configuration Summary
The SAM3U series differ in memory sizes, package and features list. Table 1-1 summarizes the
configurations of the six devices.
Note:
1. The SRAM size takes into account the 4-Kbyte RAM buffer of the NAND Flash Controller (NFC) which can be used by the
core if not used by the NFC.
