Product Description

Atmel’s SmartConnect-WINC1500 is an IEEE 802.11 b/g/n IOT network controller SoC. It is the ideal add-on to existing MCU solutions, bringing WiFi and Network capabilities through the UART or SPI-to-WiFi interface.

Atmel SMART SAM4C microcontrollers are system-on-chip solutions built around two high-performance 32-bit ARM Cortex-M4 RISC processors for smart energy applications.

These MCUs operate up to 120 MHz and feature up to 2 Mbytes of embedded Flash, up to 304 Kbytes of SRAM and on-chip cache for each core.

The dual ARM Cortex-M4 architecture allows f an application layer, communications layers and security functions to be integrated into a single device. A 16-bit external bus interface also makes it possible to to extend program and data memory.

The peripheral set includes advanced cryptographic engine, anti-tamper, floating point unit (FPU), USB Full-speed Host/Device port, five USARTs, two UARTs, two TWIs, up to seven SPIs, as well as a PWM timer, two 3-channel general-purpose 16-bit timers, calibrated low-power RTC running on the backup domain down to 0.5 μA, and a 50 × 6 segmented LCD controller.

The SAM4C series is a scalable platform that enables unprecedented cost structure, performance and flexibility to smart meter designers worldwide.
