SAM4C4C
Features for Residential and C&I Smart Meters
Description
The Microchip SAM4C 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 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 for integration of an application layer, munications 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 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 generalpurpose 16-bit timers, calibrated low-power RTC running on the backup domain down to 0.5 µA, and a 50 × 6 segmented LCD controller.
