AT91SAM9G45C-CU Description

Short technical summary and product information.

The AT91SAM9G45C-CU is an ARM926EJ-S based embedded microprocessor from Microchip Technology, operating at 400 MHz. It integrates a 32 KB data cache and a 32 KB instruction cache with a Memory Management Unit (MMU). The device includes 64 KB of internal SRAM accessible via a Tightly Coupled Memory (TCM) interface and 64 KB of internal ROM for bootstrap routines.

 

This microprocessor supports a wide range of memory interfaces including LPDDR, LPSDR, DDR2, SDR, and SRAM via its RAM controllers. It provides three USB 2.0 ports, a 10/100 Mbps Ethernet MAC, and controllers for LCD and resistive touchscreen displays. The internal 133 MHz multi-layer AHB bus matrix with 37 DMA channels sustains high data throughput.

 

The AT91SAM9G45C-CU is supplied in a 324-ball TFBGA package with a 0.8 mm ball pitch and is designed for surface mount assembly. The I/O supply voltage is configurable for 1.8V or 3.3V operation. It is rated for an operating temperature range of -40°C to 85°C.
