SAM3S8/SD8 Summary
1.
Description
The Atmel SAM3S8/SD8 series is a member of a family of Flash microcontrollers based on the
high performance 32-bit ARM Cortex-M3 RISC processor. It operates at a maximum speed of
64 MHz and features up to 512 Kbytes of Flash (dual plane on SAM3SD8) and up to 64 Kbytes
of SRAM. The peripheral set includes a Full Speed USB Device port with embedded transceiver,
a High Speed MCI for SDIO/SD/MMC, an External Bus Interface featuring a Static Memory Con-
troller providing connection to SRAM, PSRAM, NOR Flash, LCD Module and NAND Flash, 2(3)x
USARTs, (3 on SAM3SD8C) 2x UARTs, 2x TWIs, 3x SPI, an I2S, as well as 1 PWM timer, 6x
general-purpose 16-bit timers (with stepper motor and quadrature decoder logic support), an
RTC, a 12-bit ADC, a 12-bit DAC and an analog comparator.
The SAM3S8/SD8 series is ready for capacitive touch thanks to the QTouch library, offering an
easy way to implement buttons, wheels and sliders.
The SAM3S8/SD8 device is a medium range general purpose microcontroller with the best ratio
in terms of reduced power consumption, processing power and peripheral set. This enables the
SAM3S8/SD8 to sustain a wide range of applications including consumer, industrial control, and
PC peripherals.
It operates from 1.62V to 3.6V and is available in 64- and 100-pin QFP, 64-pin QFN, and 100-pin
BGA packages.
The SAM3S8/SD8 series is the ideal migration path from the SAM7S series for applications that
require more performance. The SAM3S8/SD8 series is pin-to-pin compatible with the SAM7S
series.
