Overview
This section introduces the Atmel SAM4C Evaluation Kit design. It introduces system-level concepts, such as power
distribution, memory, and interface assignments.
The Atmel SAM4C16C and SAM4C8C microcontrollers are system-on-chip solutions for smart energy applications, built
around two high-performance 32-bit ARM Cortex-M4 RISC processors. These devices operate at a maximum speed of
120 MHz and feature up to 1 Mbyte of embedded Flash, 152 Kbytes of SRAM and on-chip cache for each core.
The dual ARM Cortex-M4 architecture allows for integration of application layer, communications layers and security
functions in a single device, with the ability to extend program and data memory via a 16-bit external bus interface. The
peripheral set includes an advanced cryptographic engine, two anti-tamper pins with time-stamping function, floating
point unit (FPU), five USARTs, two UARTs, two TWIs, up to seven SPIs, as well as a PWM timer, two 3-channel general-
purpose 16-bit timers, temperature compensable low-power RTC running on backup area down to 0.5 µA, and a 50 x 6
segmented LCD controller.
The SAM4C series is a scalable platform providing, alongside Atmel's industry leading SAM4 standard microcontrollers,
unprecedented cost structure, performance and flexibility to smart meter designers worldwide.
