Atmel samples 32-bit ARM Cortex -M3-based
MCUs with 1MB Flash and 128KB SRAM
Atmel Corporation is sampling its 32-bit ARM Cortex -M3-based
microcontrollers (MCUs) with 1MB embedded Flash and 128KB
SRAM. The new Atmel SAM3S16 Cortex-M3 MCU offers high performance,
low power and large memory density for applications demanding
modern user interfaces including capacitive touch, increased
data processing and connectivity. Target applications include
medical equipment, building and home control, industrial
automation, Machine-to-Machine (M2M), test and measurement,
smart grid, and data input/output peripherals for consumer
and computing devices.
The Atmel SAM3S16 Cortex-M3 MCU is pin-to-pin compatible
with existing Atmel SAM3N and SAM3S Cortex-M3 MCUs, and
also supports In System Programming and development tools
from Atmel and third party ecosystem partners. The device
operates at a maximum speed of 100MHz with 1024KB Flash
and 128KB SRAM and includes a full peripheral set, featuring
full-speed USB, high-speed MCI for SDIO/SD/MMC, 4 UART,
TWIs, SPI, I2S and an external bus interface supporting
PSRAM, NOR Flash, LCD Modules and NAND Flash.
"The SAM3S16 is further evidence that Atmel is a leader
in microcontrollers and brings innovative and easy-to-use
ARM-based products to market, addressing the need for higher
performance, additional memory density and lower power,"
said Jacko Wilbrink, director of ARM marketing, Atmel Corporation.
"Using 90nm embedded Flash technology enables Atmel
to integrate 1MB of Flash, 128KB of SRAM and extensive peripheral
set on a monolithic Cortex-M3 microcontroller running up
to 100MHz."
Atmel supports capacitive touch buttons, slider and wheel
(BSW) capability on the Atmel SAM3S16 Cortex-M3 MCUs through
the Atmel QTouch library. The SAM3S16 operates from 1.62V
to 3.6V and can achieve 200 uA/Mhz in dynamic mode at a
low operating frequency; 30mA at 100MHz; and 3uA at 1.8
V in back-up mode with the RTC (real-time clock) running.
Availability: Early sampling of the Atmel ATSAM3S16CA-AU
Cortex-M3 MCU is available now in a 100-pin QFP package
for alpha customers. Production quantities will be available
in Q1 2012.
