Atmel’s SAM7S, SAM7XC, SAM7A3 flash based ARM7 series are real single-chip solutions. By now expanding the SAM7S peripheral-set with a real powerful external bus interface (EBI) , that supports 16/32 bit SDRAM, 8/16 bit Flash, SRAM as well as CompactFlash® and a hardware error code correction (ECC), the new SAM7SE family is born.
SAM7SE is a functional compatible product to SAM7S with additional enhancements like Schmitt-Trigger inputs, Master/Slave Multi-Master I²C (TWI), Memory protection unit (MPU), 8 USP endpoints and up to 88 IO lines.

Available with on-chip Flash memory densities of 32K, 256K and 512K bytes, the AT91SAM7SE microcontrollers also include the same supervisory features found on 8-bit MCUs including a brown-out detector, power-on-reset, real-time clock, crystal oscillator, watchdog timer and three 16-bit timers. Communication interfaces include three U(S)ARTs, USB, TWI, I2S (SSC) and SPI. The device also has four pulse width modulators (PWM), an 8-channel, 10-bit analog-to-digital converter (ADC) and 88 I/O pins.
SAM7SE boots by internal security flash and gives you full protection of your intellectual property.

Like Atmel’s other AT91SAM7 MCUs, the AT91SAM7SE-series has an 11-channel peripheral DMA controller (PDC) that increases on-chip bandwidth to 10 Mbps while maintaining 96% of the CPU’s cycles for application processing. The PDC can store the streaming content directly in the external NAND Flash or SDRAM without CPU intervention making these MCUs ideal for data logging applications such as ambulatory medical monitoring.

Based on SAM7S peripheral set, Atmel introduces full pin and functional compatible SAM7SE family. Packages LQFP128 (20 x 14 mm) and very small BGA144 (10 x 10mm) are available.
With SAM7SE even existing SAM7S applications easily can be ported to more memory- or IO- hungry solutions.
