AT91SAM9260B-CU 32-bit ARM926EJ-S Embedded Microprocessor IC
The AT91SAM9260B-CU is a high-performance, cost-effective 32-bit embedded microprocessor manufactured by Microchip Technology (formerly Atmel), built around the ARM926EJ-S core operating at up to 180 MHz. Integrating 8KB instruction cache, 8KB data cache, 8KB on-chip SRAM, and 32KB boot ROM, it features a 32-bit external bus interface (EBI) for SDRAM, NAND Flash, and static memory, plus a rich set of communication peripherals. Housed in a compact 217-pin LFBGA package, it operates at 1.8V core and 3.3V I/O voltage, supporting an industrial temperature range of –40°C to +85°C, making it ideal for embedded systems requiring balanced performance, connectivity, and reliability.
This microprocessor combines robust processing power, flexible memory options, and comprehensive connectivity:
● It delivers 180 MHz ARM926EJ-S core performance with Jazelle technology for efficient Java execution and an MMU for Linux-based systems
● 8KB I-cache, 8KB D-cache, 8KB SRAM, and 32KB ROM enable fast boot and single-cycle data access
● 32-bit EBI supports SDRAM, NAND Flash (with 1-bit ECC), and CompactFlash for scalable storage
● On-chip peripherals include 10/100 Ethernet MAC, USB 2.0 Host/Device, 6 USARTs, 2 SPIs, 1 I2C, and a 4-channel 10-bit ADC
● Low-power modes and a PLL-based clock generator optimize energy use, while the 217-pin LFBGA package ensures space-efficient integration
