MICROCHIP ATSAMA5D27-SOM1

The Microchip SAMA5D27 SOM1 is a small single-sided System-On-Module (SOM) based on the high-performance System-in-Package 32-bit Arm Cortex-A5 processor-based MPU SAMA5D27 and 1Gb DDR2 SDRAM running up to 500 MHz. The SOM also limits design rules of the main application board, reducing overall PCB complexity and cost. The SAMA5D27 SOM1 is delivered with a free Linux distribution and bare metal C examples. The SAMA5D27 SOM1 is a high-performance System-On-Module based on the 32-bit ARM Cortex-A5 RISC SAMA5D2 processor. The SAMA5D27 SOM1 is certified for industrial operating conditions over a -40 to 85℃ temperature range. The system of the SAMA5D27 SOM1 operates at a maximum CPU operating frequency of 500 MHz and a maximum bus speed of 166 MHz. It features up to:

• 1 Gbit of DDR2 SDRAM memory (SAMA5D27C-D1G-CU)
• 1 Kb of EEPROM memory (24AA02E48T-I/OT) with EUI-48
• 64 Mb of QSPI Flash (SST26VF064BT-104I/MF) memory The SAMA5D27 SOM1 is a 176-pin, 0.8 mm pad pitch module, 40 mm × 38 mm in size. The SAMA5D27 SOM1 offers an extensive peripheral set, including High-speed USB Host and Device, HSIC Interface, 10Base-T/100Base-TX Ethernet Interface, system control and up to 103 I/Os featuring:
• Up to 4 UARTs
• Up to 4 Flexcoms
• Up to 6 Capactive Touch lines for up to 9 touch buttons
• Up to 10 ADC Inputs
• Up to 2 CAN
• Up to 7 Tamper Pins
• Serial Interfaces such as SPI, TWI, QSPI, SSC and I²S
• SD/MMC, eMMC, SDIO Interfaces
• Up to 24-bit LCD RGB Interface
• CMOS Camera Interface
• Mono PDMIC and Full-Bridge Class-D Stereo
• Up to 6 Capacitive Touch Lines Each I/O of the SAMA5D27 SOM1 is configurable, as either a general-purpose I/O line only, or as an I/O line multiplexed with up to six peripheral I/Os. As the multiplexing is hardware-defined, the hardware designer and programmer must carefully determine the configuration of the PIO Controllers required by their application.
