The Atmel®|SMART SAM4S series is a member of a family of Flashmicrocontrollers based on the high-performance 32-bit ARM® Cortex®-M4 RISCprocessor. It operates at a maximum speed of 120 MHz and features up to2048 Kbytes of Flash, with optional dual-bank implementation and cachememory, and up to 160 Kbytes of SRAM. The peripheral set includes a full-speedUSB Device port with embedded transceiver, a high-speed MCI forSDIO/SD/MMC, an External Bus Interface featuring a Static Memory Controller toconnect to SRAM, PSRAM, NOR Flash, LCD Module and NAND Flash, 2USARTs, 2 UARTs, 2 TWIs, 3 SPIs, an I2S, as well as a PWM timer, two 3-channel general-purpose 16-bit timers (with stepper motor and quadraturedecoder logic support), an RTC, a 12-bit ADC, a 12-bit DAC and an analogcomparator.
