Atmel SAM9 ARM Microcontrollers Support DDR2, LCD, Touchscreen

Atmel Corporation has added five new members to their Atmel SAM9 ARM926 family of microcontrollers. The new microcontrollers support LCD control with overlays, and DDR2 memory support.

The new Atmel SAM9 part numbers are SAM9G15, SAM9G25, SAM9G35, SAM9X25, and SAM9X35. The new devices are in Atmel's 90nm technology and at 400MHz run at only 110mW

Atmel SAM9X35 Features
Features of the new Atmel SAM9X35 microcontrollers include:

• 400MHz ARM926 core
   Core requires external 1V supply
   16KB I-cache and 16KB D-cache
• External bus interface for DDR2, LP5DR, SDR, LPDDR, and NAND Flash
• Boot ROM
• 32 KB SRAM
• Power-On Reset
• Watchdog
• Real-time clock
• 21-channel DMA (DMA is a Master on the bus matrix)
• Four 16-bit PWM
• Six 32-bit Timers
• 12-channel 10-bit ADC (384k samples/sec, ±2LSB DNL and ±3LSb INL)
• LCD Controller with 2D hardware accelerator and 4 layer overlay support
• I²S
• Resistive touchscreen support
• Soft Modem
• 3 USARTs
• 3 USB Ports (2 can be Host)
• 3 UARTs
• 5 SPI
• 3 TWI
• 2 CAN 2.0
• 2 High Speed SDIO interfaces
• 10/100 Ethernet interface (E-MAC)
• 105 I/O pins (3.3V)

Atmel has teamed up with Conexant to provide soft modem implementation. 24-bit ECC mechanism on SLC and MLC NAND memories allow customers to use latest high-density memories.

Target applications for lead customers include:

• Host processor for access control systems (Atmel SAM9G25)
• High-end thermostats (Atmel SAM9G15/G35)
• Industrial control (Atmel SAM9G25/X25)
• Smart grid (Atmel SAM9G25/SAM9X25)
• EV charging stations (Atmel SAM9G35)
• Fleet management (Atmel SAM9X35)
• Secondary processor for camcorders (Atmel SAM9G25)

The new Atmel SAM9 microcontrollers also include an advanced graphics LCD controller with hardware acceleration support. The enhanced LCD controller hardware supports video overlays, alpha blending, image scaling, rotating and color space conversion. This can significantly lessen the load on the CPU core.

Availability and Pricing
"The SAM9G15, SAM9G25, SAM9G35, SAM9X25, SAM9X35 are available now in a 0.8mm ball pitch 217-ball BGA package. The SAM9G25 also ships in a 0.5mm ball pitch 247-pin BGA package. Pricing starts at $6.01 USD in 1,000-piece quantities."
