Microchip Technology 32-Bit SAM 4 Microcontrollers
Microchip Technology 32-Bit SAM 4 Microcontrollers are based on the Arm® Cortex®-M4 core, operate at a maximum CPU speed of 120MHz, and feature up to 2048KB of Flash and up to 128KB of SRAM. The SAM 4 MCU family includes the connectivity-rich SAM 4E MCUs, the low-power SAM 4L MCUs, and the entry-level SAM 4N MCUs.
The Microchip Technology SAM 4E MCUs offer a 10/100 Mbps Ethernet MAC supporting IEEE 1588 and dual CAN. With a single-precision FPU, advanced analog features, and security with 128-bit Advanced Encryption Standard (AES), the SAM 4E MCUs are ideal for industrial automation and building control applications.
The SAM 4L MCUs deliver an ultra-low-power in active mode (down to 90µA/MHz) as well as a sleep mode with full RAM retention (1.5µA) and a short wake-up time (down to 1.5µs). Integrated QTouch® technology enables capacitive touch functionality without any external components.
The SAM 4N MCUs are entry-level Cortex-M4 based devices with has seven UARTs, four SPIs, and three I2Cs. Additional features include 12-bit ADC, 10-bit DAC, integrated voltage reference, multiple timers, and PWM.
The SAM 4S MCUs offer memory densities up to 2MB of Flash, with dual bank capability, and 160KB of SRAM.
