SAM4S Arm® Flash Microcontrollers

Microchip Technology SAM4S Arm® Flash Microcontrollers (MCUs) are based on the high-performance 32-bit Arm Cortex®-M4 RISC processor. The SAM4S MCUs operate at a maximum speed of 120MHz and feature up to 2048KB of Flash, with optional dual-bank implementation and cache memory, and up to 160KB of SRAM. The peripheral set includes a full-speed USB Device port with embedded transceiver, a high-speed MCI for SDIO/SD/MMC, an External Bus Interface featuring a Static Memory Controller to connect to SRAM, PSRAM, NOR Flash, LCD Module and NAND Flash, 2 USARTs, 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 quadrature decoder logic support), an RTC, a 12-bit ADC, a 12-bit DAC, and an analog comparator.
