Микроконтроллеры ARM ATSAM4S16BA-MU

Микроконтроллер ARM , SAM32 Family SAM 4S Series Microcontrollers, ARM Cortex-M4, 32бита, 120 МГц

The ATSAM4S16BA-MU is a SMART SAM4S series 32-bit Flash Microcontroller based on the high-performance ARM Cortex-M4 RISC processor. It operates at a maximum speed of 120MHz and features 1MB of flash memory and 128kB of SRAM. 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. The device operate from 1.62V to 3.6V. It is ready for capacitive touch, offering native support for the Atmel QTouch® library for easy implementation of buttons, wheels and sliders. The real-time event management allows peripherals to receive, react to and send events in active and sleep modes.
