The AT91R40008-66AU-999 is a member of the AT91 16/32-bit microcontroller family based on the ARM7TDMI processor core. It combines a high-performance 32-bit RISC architecture with a high-density 16-bit Thumb instruction set and low power consumption. The device includes 256K bytes of on-chip SRAM with a 32-bit data bus for single-cycle access.
Operating at a clock frequency of 66MHz (maximum 75MHz at 1.8V, 85°C), the microcontroller features a fully programmable External Bus Interface (EBI) supporting up to 64M bytes of external address space with eight chip selects and software programmable 8/16-bit external data bus. Peripherals include two USARTs with dedicated PDC channels, a three-channel 16-bit timer/counter, a watchdog timer, and an eight-level priority vectored interrupt controller with four external interrupts.
The device supports advanced power-saving features allowing individual deactivation of the CPU and peripherals. It operates over a core supply voltage range of 1.65V to 1.95V and an I/O supply range of 2.7V to 3.6V. The AT91R40008-66AU-999 is available in a 100-lead LQFP green package and is rated for -40°C to +85°C temperature range.
