Device Overview

Summary

The Microchip's ARM®-based SAM9G20 is a 400MHz ARM926-based processor with an extensive range of communication peripherals. It embeds Full Speed USB host and device interfaces, a 10/100 Ethernet MAC and an image sensor interface, as well as standard peripherals such as a multimedia card interface (MCI), I2S, USART, master/slave SPIs, 16-bit timers, TWI and four-channel 10-bit ADC. The external bus interface features controllers for SDRAM and static memories including NAND flash and CompactFlash. The SAM9G20 is pin-to-pin compatible with the SAM9260. The device is available in 217-ball LFBGA and 247-pin TFBGA packages.

AT91SAM-ICE
SAM-ICE ( AT91SAM-ICE )

The SAM-ICE catalog part number (CPN) is now End of Life (EOL) and can no longer be offered.

For MPU and SAM developers, SAM-ICE has been replaced by the J-32 Debug Probe (DV164232)

Alternatively, SAM developers can use either Atmel ICE (

SAM-BA software provides an open set of tools for in-system programming of internal and external memories connected to our 32-MCUs and MPUs. You can program your device through the JTAG, debug UART or USB interfaces. If you use the MPU’s secure boot feature, you should use the Secure SAM-BA edition.

The latest generations of MPUs are supported on SAM-BA v3 available on the
